Bertrand Russell

Biography

Early life and background

Bertrand Arthur William Russell was born at Ravenscroft, a country house in Trellech, Monmouthshire, on 18 May 1872, into an influential and liberal family of the British aristocracy. His parents were Viscount and Viscountess Amberley. Both were early advocates of birth control at a time when this was considered scandalous. Lord Amberley consented to his wife's relationship with their children's tutor, the biologist Douglas Spalding. Lord Amberley, a deist, asked the philosopher John Stuart Mill to act as Russell's secular godfather. Mill died the year after Russell's birth, but his writings later influenced Russell's life.

Russell's paternal grandfather, Lord John Russell, later 1st Earl Russell, had twice been Prime Minister of the United Kingdom in the 1840s and 1860s. A member of Parliament since the early 1810s, he met Napoleon in Elba. The Russells had been prominent in England for several centuries before this, coming to power and the peerage with the rise of the Tudor dynasty (see: Duke of Bedford). They established themselves as one of the leading Whig families and participated in political events from the dissolution of the monasteries in 1536–1540 to the Glorious Revolution in 1688–1689 and the Great Reform Act in 1832.

Lady Amberley was the daughter of Lord and Lady Stanley of Alderley. Russell often feared the ridicule of his maternal grandmother, one of the campaigners for education of women.

Childhood and adolescence

Russell had two siblings: brother Frank (seven years older), and sister Rachel (four years older). In June 1874 Russell's mother died of diphtheria, followed shortly by Rachel's death. In January 1876, his father died of bronchitis after a long period of depression. Frank and Bertrand were placed in the care of paternal grandparents, who lived at Pembroke Lodge in Richmond Park. His grandfather, former Prime Minister Earl Russell, died in 1878, and was remembered by Russell as a kind old man in a wheelchair. His grandmother, the Countess Russell (née Lady Frances Elliot), was the central family figure for the rest of Russell's childhood and youth. The Countess was from a Scottish Presbyterian family and petitioned the Court of Chancery to set aside a provision in Amberley's will requiring the children to be raised as agnostics. Despite her religious conservatism, she held progressive views in other areas (accepting Darwinism and supporting Irish Home Rule), and her influence on Bertrand Russell's outlook on social justice and standing up for principle remained with him throughout his life.

Russell's adolescence was lonely and he contemplated suicide. He remarked in his autobiography that his interests in "nature and books and (later) mathematics saved me from complete despondency;" only his wish to know more mathematics kept him from suicide. He was educated at home by a series of tutors. When Russell was eleven, his brother Frank introduced him to the work of Euclid, which he described in his autobiography as "one of the great events of my life, as dazzling as first love".

During these formative years, he also discovered the works of Percy Bysshe Shelley. Russell wrote: "I spent all my spare time reading him, and learning him by heart, knowing no one to whom I could speak of what I thought or felt, I used to reflect how wonderful it would have been to know Shelley, and to wonder whether I should meet any live human being with whom I should feel so much sympathy." Russell said that beginning at age 15, he spent considerable time thinking about the validity of Christian religious dogma, which he found unconvincing. At this age, he came to the conclusion that there is no free will and, two years later, that there is no life after death. Finally, at the age of 18, after reading Mill's Autobiography, he abandoned the "First Cause" argument and became an atheist.

He travelled to the continent in 1890 with an American friend, Edward FitzGerald, and with FitzGerald's family he visited the Paris Exhibition of 1889 and climbed the Eiffel Tower soon after it was completed.

Education

Russell won a scholarship to read for the Mathematical Tripos at Trinity College, Cambridge, and began his studies there in 1890, taking as coach Robert Rumsey Webb. He became acquainted with the younger George Edward Moore and came under the influence of Alfred North Whitehead, who recommended him to the Cambridge Apostles. He distinguished himself in mathematics and philosophy, graduating as seventh Wrangler in the former in 1893 and becoming a Fellow in the latter in 1895. During his time at Cambridge, Russell increasingly turned from mathematics toward philosophy, influenced by contemporary debates about idealism and the foundations of geometry. Although initially sympathetic to British Idealism, he later rejected it, developing the realist approach that would become central to analytic philosophy. His early academic work focused on the logical foundations of mathematics, culminating in his first major publication, An Essay on the Foundations of Geometry (1897).

Russell's election to a Fellowship at Trinity College in 1895 provided him with financial independence and the freedom to pursue research. During these formative years, he began the investigations into logic and set theory that would eventually lead to his work on logicism and his collaboration with Alfred North Whitehead on Principia Mathematica.

Early career

Russell began his published work in 1896 with German Social Democracy, a study in politics that was an early indication of his interest in political and social theory. In 1896 he taught German social democracy at the London School of Economics. He was a member of the Coefficients dining club of social reformers set up in 1902 by the Fabian campaigners Sidney and Beatrice Webb.

He now started a study of the foundations of mathematics at Trinity. In 1897, he wrote An Essay on the Foundations of Geometry (submitted at the Fellowship Examination of Trinity College) which discussed the Cayley–Klein metrics used for non-Euclidean geometry. He attended the first International Congress of Philosophy in Paris in 1900 where he met Giuseppe Peano and Alessandro Padoa. The Italians had responded to Georg Cantor, making a science of set theory; they gave Russell their literature including the Formulario mathematico. Russell was impressed by the precision of Peano's arguments at the Congress, read the literature upon returning to England, and came upon Russell's paradox. In 1903 he published The Principles of Mathematics, a work on the foundations of mathematics. It advanced a thesis of logicism, that mathematics and logic are one and the same.

In February 1901, at the age of 29, Russell underwent what he called a "sort of mystic illumination", after witnessing Whitehead's wife's suffering in an angina attack. "I found myself filled with semi-mystical feelings about beauty and with a desire almost as profound as that of the Buddha to find some philosophy which should make human life endurable", Russell would later recall. "At the end of those five minutes, I had become a completely different person."

In 1905, he wrote the essay "On Denoting", which was published in the philosophical journal Mind. Russell was elected a Fellow of the Royal Society (FRS) in 1908. The three-volume Principia Mathematica, written with Whitehead, was published between 1910 and 1913. This, along with the earlier The Principles of Mathematics, soon made Russell world-famous in his field. Russell's first political activity was as the Independent Liberal candidate in the 1907 by-election for the Wimbledon constituency, where he was not elected.

In 1910, he became a lecturer at the University of Cambridge, Trinity College, where he had studied. He was considered for a fellowship, which would give him a vote in the college government and protect him from being fired for his opinions, but was passed over because he was "anti-clerical", because he was agnostic. He was approached by the Austrian engineering student Ludwig Wittgenstein, who started undergraduate study with him. Russell viewed Wittgenstein as a successor who would continue his work on logic. He spent hours dealing with Wittgenstein's various phobias and his bouts of despair. This was a drain on Russell's energy, but Russell continued to be fascinated by him and encouraged his academic development, including the publication of Wittgenstein's Tractatus Logico-Philosophicus in 1922. Russell delivered his lectures on logical atomism, his version of these ideas, in 1918, before the end of World War I.

First World War

During World War I, Russell was one of the few people to engage in active pacifist activities. In 1916, due to his absence of allegiance to the war effort, he was dismissed from Trinity College following his conviction under the Defence of the Realm Act 1914. He later described this, in Free Thought and Official Propaganda, as an illegitimate means the state used to violate freedom of expression. Russell championed the case of Eric Chappelow, a poet jailed and abused as a conscientious objector. Russell played a part in the Leeds Convention in June 1917, a historic event which saw well over a thousand "anti-war socialists" gather; many being delegates from the Independent Labour Party and the British Socialist Party, united in their pacifist beliefs and advocating a peace settlement. The international press reported that Russell appeared with a number of Labour Members of Parliament (MPs), including Ramsay MacDonald and Philip Snowden, as well as former Liberal MP and anti-conscription campaigner, Professor Arnold Lupton. After the event, Russell told Lady Ottoline Morrell that, "to my surprise, when I got up to speak, I was given the greatest ovation that was possible to give anybody".

His conviction in 1916 resulted in Russell being fined £100 (equivalent to £6,000 in 2025), which he refused to pay in the hope that he would be sent to prison, but his books were sold at auction to raise the money. The books were bought by friends; he later treasured his copy of the King James Bible that was stamped "Confiscated by Cambridge Police".

A later conviction for publicly lecturing against inviting the United States to enter the war on the United Kingdom's side resulted in six months' imprisonment in Brixton Prison (see Bertrand Russell's political views) in 1918 (he was prosecuted under the Defence of the Realm Act). He later said of his imprisonment:

I found prison in many ways quite agreeable. I had no engagements, no difficult decisions to make, no fear of callers, no interruptions to my work. I read enormously; I wrote a book, "Introduction to Mathematical Philosophy"... and began the work for "The Analysis of Mind". I was rather interested in my fellow-prisoners, who seemed to me in no way morally inferior to the rest of the population, though they were on the whole slightly below the usual level of intelligence as was shown by their having been caught.

While he was reading Strachey's Eminent Victorians chapter about Gordon he laughed out loud in his cell prompting the warder to intervene and reminding him that "prison was a place of punishment".

G. H. Hardy on the Trinity controversy

In 1941, G. H. Hardy wrote a 61-page pamphlet titled Bertrand Russell and Trinity (published later as a book by Cambridge University Press with a foreword by C. D. Broad) in which he gave an authoritative account of Russell's 1916 dismissal from Trinity College, explaining that a reconciliation between the college and Russell had later taken place and gave details about Russell's personal life. Hardy writes that Russell's dismissal had created a scandal since the vast majority of the Fellows of the College opposed the decision. The ensuing pressure from the Fellows induced the Council to reinstate Russell. In January 1920, it was announced that Russell had accepted the reinstatement offer from Trinity and would begin lecturing in October. In July 1920, Russell applied for a one-year leave of absence; this was approved. He spent the year giving lectures in China and Japan. In January 1921, it was announced by Trinity that Russell had resigned and his resignation had been accepted. This resignation, Hardy explains, was voluntary and was not the result of another altercation.

The reason for the resignation, according to Hardy, was that Russell was going through a tumultuous time in his personal life with a divorce and subsequent remarriage. Russell contemplated asking Trinity for another one-year leave of absence but decided against it since this would have been an "unusual application" and the situation had the potential to snowball into another controversy. Although Russell did the right thing, in Hardy's opinion, the reputation of the College suffered with Russell's resignation since the 'world of learning' knew about Russell's altercation with Trinity but not that the rift had healed. In 1925, Russell was asked by the Council of Trinity College to give the Tarner Lectures on the Philosophy of the Sciences; these would later be the basis for one of Russell's best-received books according to Hardy: The Analysis of Matter, published in 1927. In the preface to the Trinity pamphlet, Hardy wrote:

I wish to make it plain that Russell himself is not responsible, directly or indirectly, for the writing of the pamphlet.... I wrote it without his knowledge and, when I sent him the typescript and asked for his permission to print it, I suggested that, unless it contained misstatement of fact, he should make no comment on it. He agreed to this... no word has been changed as the result of any suggestion from him.

Between the wars

In August 1920, Russell travelled to Soviet Russia as part of an official delegation sent by the British government to investigate the effects of the Russian Revolution. He wrote a four-part series of articles, titled "Soviet Russia—1920", for the magazine The Nation. He met Vladimir Lenin and had an hour-long conversation with him. In his autobiography, he mentions that he found Lenin disappointing, sensing an "impish cruelty" in him and comparing him to "an opinionated professor". He cruised down the Volga on a steamship. His experiences destroyed his previous tentative support for the revolution. He subsequently wrote a book, The Practice and Theory of Bolshevism, about his experiences on this trip,The Russian authorities only admitted me on the express condition that I should travel with the British Labour Delegation ... I, not being a member of the Delegation, felt less obligation than my companions did to attend at propaganda meetings where one knew the speeches by heart beforehand. In this way, I was able, by the help of neutral interpreters, mostly English or American, to have many conversations with casual people whom I met in the streets or on village greens, and to find out how the whole system appears to the ordinary non-political man and woman.

Russell's lover Dora Black, a British author, feminist and socialist campaigner, visited Soviet Russia independently at the same time; in contrast to his reaction, she was enthusiastic about the Bolshevik revolution.

The following year, Russell, accompanied by Dora, visited Peking (Beijing) to lecture on philosophy for a year. He went with optimism and hope, seeing China as then being on a new path. Other scholars present in China at the time included John Dewey and Rabindranath Tagore, the Indian Nobel-laureate poet. Before leaving China, Russell became gravely ill with pneumonia, and incorrect reports of his death were published in the Japanese press. When the couple visited Japan on their return journey, Dora took on the role of spurning the local press by handing out notices reading "Mr. Bertrand Russell, having died according to the Japanese press, is unable to give interviews to Japanese journalists". Apparently they found this harsh and reacted resentfully. Russell supported his family during this time by writing popular books explaining matters of physics, ethics, and education to the layman.

From 1922 to 1927, the Russells divided their time between London and Cornwall, spending summers in Porthcurno. In the 1922 and 1923 general elections Russell stood as a Labour Party candidate in the Chelsea constituency, but only on the basis that he knew he was unlikely to be elected in such a safe Conservative seat, and he was unsuccessful on both occasions.

Second World War

Russell's political views changed over time, mostly about war. He opposed rearmament against Nazi Germany. In 1937, he wrote in a personal letter: "If the Germans succeed in sending an invading army to England we should do best to treat them as visitors, give them quarters and invite the commander and chief to dine with the prime minister." In 1940, he changed his appeasement view that avoiding a full-scale world war was more important than defeating Hitler. He concluded that Adolf Hitler taking over all of Europe would be a permanent threat to democracy. In 1943, he adopted a stance toward large-scale warfare called "relative political pacifism": "War was always a great evil, but in some particularly extreme circumstances, it may be the lesser of two evils."

Before World War II, Russell taught at the University of Chicago, later moving on to Los Angeles to lecture at the UCLA Department of Philosophy. He was appointed professor at the City College of New York (CCNY) in 1940, but after a public outcry the appointment was annulled by a court judgment that pronounced him "morally unfit" to teach at the college because of his opinions, especially those relating to sexual morality, detailed in Marriage and Morals (1929). The matter was taken to the New York Supreme Court by Jean Kay who was afraid that her daughter would be harmed by the appointment, though her daughter was not a student at CCNY. Many intellectuals, led by John Dewey, protested at his treatment. Albert Einstein's oft-quoted aphorism that "great spirits have always encountered violent opposition from mediocre minds" originated in his open letter, dated 19 March 1940, to Morris Raphael Cohen, a professor emeritus at CCNY, supporting Russell's appointment. Dewey and Horace M. Kallen edited a collection of articles on the CCNY affair in The Bertrand Russell Case. Russell soon joined the Barnes Foundation, lecturing to a varied audience on the history of philosophy; these lectures formed the basis of A History of Western Philosophy. His relationship with the eccentric Albert C. Barnes soon soured, and he returned to the UK in 1944 to rejoin the faculty of Trinity College.

Later life

Russell participated in many broadcasts over the BBC, particularly The Brains Trust and for the Third Programme, on various topical and philosophical subjects. By this time Russell was known outside academic circles, frequently the subject or author of magazine and newspaper articles, and was called upon to offer opinions on a variety of subjects, even mundane ones. En route to one of his lectures in Trondheim, Russell was one of 24 survivors (out of 43 passengers) of an aeroplane crash in Hommelvik in October 1948. He said he owed his life to smoking since the people who drowned were in the non-smoking part of the plane. A History of Western Philosophy (1945) became a best-seller and provided Russell with a steady income for the remainder of his life.

In 1942, Russell argued in favour of a moderate socialism, capable of overcoming its metaphysical principles. In an inquiry on dialectical materialism, launched by the Austrian artist and philosopher Wolfgang Paalen in his journal DYN, Russell said: "I think the metaphysics of both Hegel and Marx plain nonsense—Marx's claim to be 'science' is no more justified than Mary Baker Eddy's. This does not mean that I am opposed to socialism."

In 1943, Russell expressed support for Zionism: "I have come gradually to see that, in a dangerous and largely hostile world, it is essential to Jews to have some country which is theirs, some region where they are not suspected aliens, some state which embodies what is distinctive in their culture".

In a speech in 1948, Russell said that if the USSR's aggression continued, it would be morally worse to go to war after the USSR possessed an atomic bomb than before it possessed one, because if the USSR had no bomb the West's victory would come more swiftly and with fewer casualties than if there were atomic bombs on both sides. At that time, only the United States possessed an atomic bomb, and the USSR was pursuing an aggressive policy towards the countries in Eastern Europe which were being absorbed into the Soviet Union's sphere of influence. Many understood Russell's comments to mean that Russell approved of a first strike in a war with the USSR, including Nigel Lawson, who was present when Russell spoke of such matters. Others, including Griffin, who obtained a transcript of the speech, have argued that he was explaining the usefulness of America's atomic arsenal in deterring the USSR from continuing its domination of Eastern Europe.

Final years and death

In June 1955, Russell had leased Plas Penrhyn in Penrhyndeudraeth, Merionethshire, Wales and on 5 July of the following year it became his and Edith's principal residence.

Russell published his three-volume autobiography in 1967, 1968, and 1969. He made a cameo appearance playing himself in the anti-war Hindi film Aman, by Mohan Kumar, which was released in India in 1967. This was Russell's only appearance in a feature film.

On 23 November 1969, he wrote to The Times newspaper saying that the preparation for show trials in Czechoslovakia was "highly alarming". The same month, he appealed to Secretary General U Thant of the United Nations to support an international war crimes commission to investigate alleged torture and genocide by the United States in South Vietnam during the Vietnam War. The following month, he protested to Alexei Kosygin over the expulsion of Aleksandr Solzhenitsyn from the Soviet Union of Writers.

On 31 January 1970, Russell issued a statement condemning "Israel's aggression in the Middle East", and in particular, Israeli bombing raids being carried out deep in Egyptian territory as part of the War of Attrition, which he compared to German bombing raids in the Battle of Britain and the US bombing of Vietnam. He called for an Israeli withdrawal to the pre-Six-Day War borders, stating "The aggression committed by Israel must be condemned, not only because no state has the right to annexe foreign territory, but because every expansion is an experiment to discover how much more aggression the world will tolerate." This was Russell's final political statement or act. It was read out at the International Conference of Parliamentarians in Cairo on 3 February 1970, the day after his death.

Russell died of influenza, just after 8 pm on 2 February 1970 at his home in Penrhyndeudraeth, aged 97. His body was cremated in Colwyn Bay on 5 February 1970 with five people present. In accordance with his will, there was no religious ceremony but one minute's silence; his ashes were later scattered over the Welsh mountains. Although he was born in Monmouthshire, and died in Penrhyndeudraeth in Wales, Russell identified as English. Later in 1970, on 23 October, his will was published showing he had left an estate valued at £69,423 (equivalent to £1 million in 2025).

Philosophy

Russell is credited with being one of the founders of analytic philosophy. He was impressed by Gottfried Leibniz (1646–1716), and wrote on major areas of philosophy except aesthetics. He was prolific in the fields of metaphysics, logic and the philosophy of mathematics, the philosophy of language, ethics and epistemology. When Brand Blanshard asked Russell why he did not write on aesthetics, Russell replied that he did not know anything about it, though he hastened to add "but that is not a very good excuse, for my friends tell me it has not deterred me from writing on other subjects".

Analytic philosophy

Bertrand Russell helped to develop what is now called "Analytic Philosophy." Alongside G. E. Moore, Russell was shown to be partly responsible for the British revolt against idealism, a philosophy greatly influenced by G. W. F. Hegel and his British apostle, F. H. Bradley. This revolt was echoed 30 years later in Vienna by the logical positivists' "revolt against metaphysics." Russell was particularly critical of a doctrine he ascribed to idealism and coherentism, which he dubbed the doctrine of internal relations; this, Russell suggested, held that to know any particular thing, we must know all of its relations. Russell argued that this would make space, time, science and the concept of number not fully intelligible. Russell's logical work with Whitehead continued this project.

Russell and Moore were devoted to clarity in arguments by breaking down philosophical positions into their simplest components. Russell, in particular, saw formal logic and science as the principal tools of the philosopher. Russell did not think we should have separate methods for philosophy. Russell thought philosophers should strive to answer the most general of propositions about the world and this would help eliminate confusions. In particular, he wanted to end what he saw as the excesses of metaphysics. Russell adopted William of Ockham's principle against multiplying unnecessary entities, Occam's razor, as a central part of the method of analysis.

Logic and philosophy of mathematics

Russell had great influence on modern mathematical logic. The American philosopher and logician Willard Van Orman Quine said Russell's work represented the greatest influence on his own work.

Russell's first mathematical book, An Essay on the Foundations of Geometry, was published in 1897. This work was heavily influenced by Immanuel Kant. The book was highly praised but according to the author "far more in fact than it deserved". Russell later realised that the conception it laid out would make Albert Einstein's schema of space-time impossible. Thenceforth, he rejected the entire Kantian program as it related to mathematics and geometry, and rejected his own earliest work on the subject.

Interested in the definition of number, Russell studied the work of George Boole, Georg Cantor, and Augustus De Morgan. Materials in the Bertrand Russell Archives at McMaster University include notes of his reading in algebraic logic by Charles Sanders Peirce and Ernst Schröder. In 1900 he attended the first International Congress of Philosophy in Paris, where he became familiar with the work of the Italian mathematician, Giuseppe Peano. He mastered Peano's new symbolism and his set of axioms for arithmetic. Peano defined logically all of the terms of these axioms with the exception of 0, number, successor, and the singular term, the, which were the primitives of his system. Russell took it upon himself to find logical definitions for each of these. Between 1897 and 1903 he published several articles applying Peano's notation to the classical Boole-Schröder algebra of relations, among them On the Notion of Order, Sur la logique des relations avec les applications à la théorie des séries, and On Cardinal Numbers. He became convinced that the foundations of mathematics could be derived within what has since come to be called higher-order logic which in turn he believed to include some form of unrestricted comprehension axiom.

Russell then discovered that Gottlob Frege had independently arrived at equivalent definitions for 0, successor, and number, and the definition of number is now usually referred to as the Frege-Russell definition. Russell drew attention to Frege's priority in 1903, when he published The Principles of Mathematics (see below). The appendix to this work, however, described a paradox arising from Frege's application of second- and higher-order functions which took first-order functions as their arguments, and Russell offered his first effort to resolve what would henceforth come to be known as the Russell Paradox. Before writing Principles, Russell became aware of Cantor's proof that there was no greatest cardinal number, which Russell believed was mistaken. Cantor's paradox in turn was shown (for example by Crossley) to be a special case of the Russell Paradox. This caused Russell to analyse classes, for it was known that given any number of elements, the number of classes they result in is greater than their number. Russell's paradox involves the class of all classes, divided into two kinds: those classes that contain themselves, and those that do not. This class demonstrates a fatal flaw in the so-called principle of comprehension, which had been taken for granted by logicians of the time: it results in a contradiction, whereby Y is a member of Y if and only if Y is not a member of Y. Russell outlined a resolution of this paradox in an appendix to Principles, which he later developed into the theory of types. Aside from exposing a major inconsistency in naive set theory, Russell's work led directly to the creation of modern axiomatic set theory. It also crippled Frege's project of reducing arithmetic to logic. The Theory of Types and much of Russell's subsequent work have also found practical applications in computer science and information technology.

Philosophy of language

Russell made language, or more specifically, how we use language, a central part of philosophy, and this influenced Ludwig Wittgenstein, Gilbert Ryle, J. L. Austin, and P. F. Strawson, among others, who used many of the techniques that Russell originally developed. Russell, and G. E. Moore, argued that clarity of expression is a virtue.

A significant contribution to philosophy of language is Russell's theory of descriptions, set out in On Denoting (Mind, 1905). Frank Ramsey described this paper as "a paradigm of philosophy." The theory considers the sentence "The present King of France is bald" and whether the proposition is false or meaningless. Frege had argued, employing his distinction between sense and reference, that such sentences were meaningful but neither true nor false. Russell argues that the grammatical form of the sentence disguises its underlying logical form. Russell's Theory of Definite Descriptions enables the sentence to be construed as meaningful but false, without commitment to the existence of any present King of France. This addresses a paradox of great antiquity (e.g. "That which is not must in some sense be. Otherwise, how could we say of it that it is not?" etc.), going back at least as far as Parmenides. In Russell's own time, Meinong held the view of that-which-is-not being in some sense real; and Russell held this view prior to On Denoting.

The problem is general to what are called "definite descriptions." Normally this includes all terms beginning with "the," and sometimes includes names, like "Walter Scott." (This point is quite contentious: Russell sometimes thought that the latter terms shouldn't be called names at all, but only "disguised definite descriptions," but much subsequent work has treated them as altogether different things.) What is the "logical form" of definite descriptions: how, in Frege's terms, could we paraphrase them to show how the truth of the whole depends on the truths of the parts? Definite descriptions appear to be like names that by their very nature denote exactly one thing, neither more nor less. What, then, are we to say about the proposition as a whole if one of its parts apparently isn't functioning correctly?

Russell's solution was, first of all, to analyse not the term alone but the entire proposition that contained a definite description. "The present king of France is bald," he then suggested, can be reworded to "There is an x such that x is a present king of France, nothing other than x is a present king of France, and x is bald." Russell claimed that each definite description in fact contains a claim of existence and a claim of uniqueness which give this appearance, but these can be broken apart and treated separately from the predication that is the obvious content of the proposition. The proposition as a whole then says three things about some object: the definite description contains two of them, and the rest of the sentence contains the other. If the object does not exist, or if it is not unique, then the whole sentence turns out to be false, not meaningless.

Logical atomism

Russell explained his philosophy of logical atomism in a set of lectures, "The Philosophy of Logical Atomism", which he gave in 1918. In these lectures, Russell sets forth his concept of an ideal, isomorphic language, one that would mirror the world, whereby our knowledge can be reduced to terms of atomic propositions and their truth-functional compounds. Logical atomism is a form of radical empiricism, for Russell believed the most important requirement for such an ideal language is that every meaningful proposition must consist of terms referring directly to the objects with which we are acquainted, or that they are defined by other terms referring to objects with which we are acquainted. Russell excluded some formal, logical terms such as all, the, is, and so forth, from his isomorphic requirement, but he was never entirely satisfied with our understanding of such terms. One of the central themes of Russell's atomism is that the world consists of logically independent facts, a plurality of facts, and that our knowledge depends on the data of our direct experience of them. In his later life, Russell came to doubt aspects of logical atomism, especially his principle of isomorphism, though he continued to believe that the process of philosophy ought to consist of breaking things down into their simplest components, even though we might not ever fully arrive at an ultimate atomic fact.

Epistemology

Russell's epistemology went through many phases. Once he shed neo-Hegelianism in his early years, Russell remained a philosophical realist for the remainder of his life, believing that our direct experiences have primacy in the acquisition of knowledge. While some of his views have lost favour, his influence remains strong in the distinction between two ways in which we can be familiar with objects: "knowledge by acquaintance" and "knowledge by description". For a time, Russell thought that we could only be acquainted with our own sense data—momentary perceptions of colours, sounds, and the like—and that everything else, including the physical objects that these were sense data of, could only be inferred, or reasoned to—i.e. known by description—and not known directly. This distinction has gained much wider application, though Russell eventually rejected the idea of an intermediate sense datum.

In his later philosophy, Russell subscribed to a kind of neutral monism, maintaining that the distinctions between the material and mental worlds, in the final analysis, were arbitrary, and that both can be reduced to a neutral property—a view similar to one held by the American philosopher/psychologist, William James, and one that was first formulated by Baruch Spinoza, whom Russell greatly admired. Instead of James' "pure experience," however, Russell characterised the stuff of our initial states of perception as "events," a stance which is curiously akin to his old teacher Whitehead's process philosophy.

Philosophy of science

Russell claimed that he was more convinced of his method of doing philosophy than of his philosophical conclusions. Science was one of the principal components of analysis. Russell was a believer in the scientific method, that science reaches only tentative answers, that scientific progress is piecemeal, and attempts to find organic unities were largely futile. He believed the same was true of philosophy. Russell held that the ultimate objective of both science and philosophy was to understand reality, not simply to make predictions.

Russell's work contributed to philosophy of science's development into a separate branch of philosophy. Much of Russell's thinking about science is expressed in his 1914 book, Our Knowledge of the External World as a Field for Scientific Method in Philosophy, which influenced the logical positivists.

Russell held that of the physical world we know only its abstract structure except for the intrinsic character of our own brain with which we have direct acquaintance (Russell, 1948). Russell said that he had always assumed copunctuality between percepts and non-percepts, and percepts were also part of the physical world, a part of which we knew its intrinsic character directly, knowledge which goes beyond structure. His views on science have become integrated into the contemporary debate in the philosophy of science as a form of Structural Realism, people such as Elie Zahar and Ioannis Votsis have discussed the implications of his work for our understanding of science. The seminal article "The Concept of Structure in The Analysis of Matter" by William Demopoulos and Michael Friedman was crucial in reintegrating Russell's views to the contemporary scene.

Russell wrote several science books, including The ABC of Atoms (1923) and The ABC of Relativity (1925).

Ethics

While Russell wrote a great deal on ethical subject matters, he did not believe that the subject belonged to philosophy or that when he wrote on ethics that he did so in his capacity as a philosopher.

Russell wrote that he was a utilitarian in his youth, yet he later distanced himself from this view. In his earlier years, Russell was greatly influenced by G.E. Moore's Principia Ethica. Along with Moore, he then believed that moral facts were objective, but known only through intuition; that they were simple properties of objects, not equivalent (e.g., pleasure is good) to the natural objects to which they are often ascribed (see Naturalistic fallacy); and that these simple, undefinable moral properties cannot be analysed using the non-moral properties with which they are associated. In time, however, he came to agree with his philosophical hero, David Hume, who believed that ethical terms dealt with subjective values that cannot be verified in the same way as matters of fact.

Coupled with Russell's other doctrines, this influenced the logical positivists, who formulated the theory of emotivism or non-cognitivism, which states that ethical propositions (along with those of metaphysics) were essentially meaningless and nonsensical or, at best, little more than expressions of attitudes and preferences. Notwithstanding his influence on them, Russell himself did not construe ethical propositions as narrowly as the positivists, for he believed that ethical considerations are not only meaningful, but that they are a vital subject matter for civil discourse. Indeed, though Russell was often characterised as the patron saint of rationality, he agreed with Hume, who said that reason ought to be subordinate to ethical considerations.

Religion

For most of his adult life Russell maintained that religion is little more than superstition and, despite any positive effects that religion might have, it is largely harmful to people. He believed religion and the religious outlook (he considered communism and other systematic ideologies to be forms of religion) serve to impede knowledge, foster fear and dependency, and are responsible for much of the war, oppression, and misery that have beset the world. He was a member of the advisory council of the British Humanist Association and the president of Cardiff Humanists until his death.

Russell described himself in 1947 as an agnostic or an atheist: he found it difficult to determine which term to adopt, saying:

Therefore, in regard to the Olympic gods, speaking to a purely philosophical audience, I would say that I am an Agnostic. But speaking popularly, I think that all of us would say in regard to those gods that we were Atheists. In regard to the Christian God, I should, I think, take exactly the same line.

In his 1949 speech, "Am I an Atheist or an Agnostic?", Russell expressed his difficulty over whether to call himself an atheist or an agnostic:

As a philosopher, if I were speaking to a purely philosophic audience I should say that I ought to describe myself as an Agnostic, because I do not think that there is a conclusive argument by which one can prove that there is not a God. On the other hand, if I am to convey the right impression to the ordinary man in the street I think that I ought to say that I am an Atheist, because, when I say that I cannot prove that there is not a God, I ought to add equally that I cannot prove that there are not the Homeric gods.

In the 1948 BBC Radio Debate between Bertrand Russell and Frederick Copleston, Russell chose to assume the position of the agnostic. It seems to have been because he admitted to not being able to prove the non-existence of God:

Copleston: Well, my position is the affirmative position that such a being actually exists, and that His existence can be proved philosophically. Perhaps you would tell me if your position is that of agnosticism or of atheism. I mean, would you say that the non-existence of God can be proved?

Political philosophy

For the advancement of science and protection of liberty of expression, Russell advocated Alfred Henry Lloyd's concept of The Will to Doubt, the recognition, expressed in his book of the same name, that all human knowledge is at most a best guess. He writes that that one should always remember:

None of our beliefs are quite true; all have at least a penumbra of vagueness and error. The methods of increasing the degree of truth in our beliefs are well known; they consist in hearing all sides, trying to ascertain all the relevant facts, controlling our own bias by discussion with people who have the opposite bias, and cultivating a readiness to discard any hypothesis which has proved inadequate. These methods are practised in science, and have built up the body of scientific knowledge.

Every man of science whose outlook is truly scientific is ready to admit that what passes for scientific knowledge at the moment is sure to require correction with the progress of discovery; nevertheless, it is near enough to the truth to serve for most practical purposes, though not for all. In science, where alone something approximating to genuine knowledge is to be found, men's attitude is tentative and full of doubt.

Russell supported freedom of opinion and was an opponent of both censorship and indoctrination. In 1928, he wrote: The fundamental argument for freedom of opinion is the doubtfulness of all our belief... when the State intervenes to ensure the indoctrination of some doctrine, it does so because there is no conclusive evidence in favour of that doctrine ... It is clear that thought is not free if the profession of certain opinions make it impossible to make a living. In 1957, he wrote: "'Free thought' means thinking freely ... to be worthy of the name freethinker he must be free of two things: the force of tradition and the tyranny of his own passions."

Russell has presented ideas on the possible means of control of education in case of scientific dictatorship governments, of the kind of this excerpt taken from Chapter II "General Effects of Scientific Technique" of "The Impact of Science on society":

This subject will make great strides when it is taken up by scientists under a scientific dictatorship. Anaxagoras maintained that snow is black, but no one believed him. The social psychologists of the future will have a number of classes of school children on whom they will try different methods of producing an unshakable conviction that snow is black. Various results will soon be arrived at. First, that the influence of home is obstructive. Second, that not much can be done unless indoctrination begins before the age of ten. Third, that verses set to music and repeatedly intoned are very effective. Fourth, that the opinion that snow is white must be held to show a morbid taste for eccentricity. But I anticipate. It is for future scientists to make these maxims precise and discover exactly how much it costs per head to make children believe that snow is black, and how much less it would cost to make them believe it is dark grey. Although this science will be diligently studied, it will be rigidly confined to the governing class. The populace will not be allowed to know how its convictions were generated. When the technique has been perfected, every government that has been in charge of education for a generation will be able to control its subjects securely without the need of armies or policemen. As yet there is only one country which has succeeded in creating this politician's paradise. The social effects of scientific technique have already been many and important, and are likely to be even more noteworthy in the future. Some of these effects depend upon the political and economic character of the country concerned; others are inevitable, whatever this character may be.

Political positions

Political and social activism occupied much of Russell's time for most of his long life, which makes his prodigious and seminal writing on a wide range of technical and non-technical subjects all the more remarkable.

Russell remained politically active to the end of his life, writing to and exhorting world leaders and lending his name to various causes. Some maintain that during his last few years he gave his youthful followers too much license and that they used his name for some outlandish purposes of which a more attentive Russell would not have approved. There is evidence to show that he became aware of this when he fired his private secretary, Ralph Schoenman, then a young firebrand of the radical left.

Russell often characterised his moral and political writings as lying outside the scope of philosophy, but Russell's admirers and detractors are often more acquainted with his pronouncements on social and political matters, or what some (e.g., biographer Ray Monk) have called his "journalism", than they are with his technical, philosophical work. There is a marked tendency to conflate these matters, and to judge Russell the philosopher on what he himself would certainly consider to be his non-philosophical opinions. Russell often cautioned people to make this distinction. Beginning in the 1920s, Russell wrote frequently for The Nation on changing morals, nuclear disarmament and literature. In 1965, he wrote that the magazine "...has been one of the few voices which has been heard on behalf of individual liberty and social justice consistently throughout its existence."

Paul McCartney, a member of The Beatles, said that after he met with Russell at his house and discussed the Vietnam war with him, McCartney inspired John Lennon and the band to take an anti-war stance.

Pacifism, war, and nuclear weapons

Russell was originally a Liberal Imperialist but in 1901 converted to anti-imperialism, pacifism and a Pro-Boer standpoint with regards to the Second Boer War. He was later involved in the Union of Democratic Control.

He resisted specific wars on the grounds that they were contrary to the interests of civilisation, and thus immoral. On the other hand, his 1915 article on "The Ethics of War", he defended wars of colonisation on the same utilitarian grounds: he felt conquest was justified if the side with the more advanced civilisation could put the land to better use.

Russell's activism against British participation in World War I led to fines, a loss of freedom of travel within Britain, and the non-renewal of his fellowship at Trinity College, Cambridge, and he was eventually sentenced to prison in 1918 on the tenuous grounds that he had interfered in British foreign policy – he had argued that British workers should be wary of the United States Army, for it had experience in strike-breaking. He was released after serving six months, but was still closely supervised until the end of the war. Russell contended that "the abolition of private ownership of land and capital is a necessary step toward any world in which the nations are to live at peace with one another".

In 1943 Russell called his stance towards warfare "relative political pacifism" – he held that war was always a great evil, but in some particularly extreme circumstances (such as when Adolf Hitler threatened to take over Europe) it might be a lesser of multiple evils. In the years leading to World War II, he supported the policy of appeasement; but by 1940 he acknowledged that to preserve democracy, Hitler had to be defeated. This same reluctant value compromise was shared by his acquaintance A.A. Milne.

Russell consistently opposed the continued existence of nuclear weapons ever since their first use. However, on 20 November 1948, in a public speech at Westminster School, addressing a gathering arranged by the New Commonwealth, Russell shocked some observers with comments that seemed to suggest a preemptive nuclear strike on the Soviet Union might be justified. Russell apparently argued that the threat of war between the United States and the Soviet Union would enable the United States to force the Soviet Union to accept the Baruch Plan for international atomic energy control. (Earlier in the year he had written in the same vein to Walter W. Marseille.) Russell felt this plan "had very great merits and showed considerable generosity, when it is remembered that America still had an unbroken nuclear monopoly." (Has Man a Future?, 1961).

Communism, anarchism and socialism

Russell was, prior to being a socialist, a Georgist.

In 1914 he wrote to Lady Ottoline Morrell saying "It is clear the Socialists are the hope of the world". Russell expressed support for guild socialism. He was also an admirer of Franklin Delano Roosevelt and Eduard Bernstein.

Russell expressed great hope in "the Communist experiment". However, when he visited the Soviet Union and met Vladimir Lenin in 1920, he was unimpressed with the system in place. On his return he wrote a critical tract, The Practice and Theory of Bolshevism. In later years he said of Lenin that he was "less impressed by Lenin than I expected to be" but also that he was a "great man". He considered him to be similar to a religious zealot as he said that Lenin believed "anything could be proved by quoting a text in Marx and he was quite incapable of supposing that there could be anything in Marx which wasn't right".

While in the Soviet Union he was "infinitely unhappy in this atmosphere – stifled by its utilitarianism, its indifference to love and beauty and the life of impulse." He was critical of Soviet Russia but still believed "that Communism is necessary to the world". Despite his criticism he nevertheless praised the Russian Revolution as "heroism" which had "fired men’s hopes in a way which was essential to the realization of Communism in the future" and that therefore "Bolshevism deserves the gratitude and admiration of all the progressive part of mankind"

Later in his life, Russell completely denounced Marxism and communism, stating that:

The theoretical doctrines of Communism are for the most part derived from Marx. My objections to Marx are of two sorts: one, that he was muddle-headed; and the other, that his thinking was almost entirely inspired by hatred. [...] I have always disagreed with Marx. My first hostile criticism of him was published in 1896. But my objections to modern Communism go deeper than my objections to Marx. It is the abandonment of democracy that I find particularly disastrous. [...] Communism is a doctrine bred of poverty, hatred and strife. Its spread can only be arrested by diminishing the area of poverty and hatred.

Women's suffrage

As a young man, Russell was a member of the Liberal Party and wrote in favour of women's suffrage. In his 1910 pamphlet, Anti-Suffragist Anxieties, Russell wrote that some men opposed suffrage because they "fear that their liberty to act in ways that are injurious to women will be curtailed." In May 1907, Russell stood for Parliament as a woman's suffrage candidate in Wimbledon, but was not elected.

Sexuality

Russell wrote against Victorian notions of morality. Marriage and Morals (1929) expressed his opinion that sex between a man and woman who are not married to each other is not necessarily immoral if they truly love one another, and advocated "trial marriages" or "companionate marriage", formalised relationships whereby young people could legitimately have sexual intercourse without being expected to remain married in the long term or to have children (an idea first proposed by Judge Ben Lindsey). This was enough to raise vigorous protests and denunciations against him during his visit to the United States shortly after the book's publication. Russell was also one of the first intellectuals to advocate open sex education and widespread access to contraception. He also advocated easy divorce, but only if the marriage had produced no children – Russell's view was that parents should remain married but tolerant of each other's sexual infidelity, if they had children. This reflected his life at the time – his second wife Dora was openly having an affair, and would soon become pregnant by another man, but Russell was keen for their children John and Kate to have a "normal" family life.

Russell was also an active supporter of the Homosexual Law Reform Society, being one of the signatories of A.E. Dyson's 1958 letter to The Times calling for a change in the law regarding male homosexual practices, which were partly legalised in 1967, when Russell was still alive.

Race

As with his views on religion, which developed considerably throughout his long life, Russell's views on the matter of race did not remain fixed. By 1951, Russell was a vocal advocate of racial equality and intermarriage; he penned a chapter on "Racial Antagonism" in New Hopes for a Changing World (1951), which read:

It is sometimes maintained that racial mixture is biologically undesirable. There is no evidence whatever for this view. Nor is there, apparently, any reason to think that Negroes are congenitally less intelligent than white people, but as to that it will be difficult to judge until they have equal scope and equally good social conditions.

Passages in some of his early writings support birth control. On 16 November 1922, for instance, he gave a lecture to the General Meeting of Dr. Marie Stopes's Society for Constructive Birth Control and Racial Progress on "Birth Control and International Relations", in which he described the importance of extending Western birth control worldwide; his remarks anticipated the population control movement of the 1960s and the role of the United Nations.

This policy may last some time, but in the end under it we shall have to give way—we are only putting off the evil day; the one real remedy is birth control, that is getting the people of the world to limit themselves to those numbers which they can keep upon their own soil... I do not see how we can hope permanently to be strong enough to keep the coloured races out; sooner or later they are bound to overflow, so the best we can do is to hope that those nations will see the wisdom of Birth Control.... We need a strong international authority.

Another passage from early editions of his book Marriage and Morals (1929), which Russell later claimed to be referring only to environmental conditioning, and which he significantly modified in later editions, reads:

In extreme cases, there can be little doubt of the superiority of one race to another [...] It seems on the whole fair to regard Negroes as on the average inferior to white men, although for work in the tropics they are indispensable, so that their extermination (apart from the question of humanity) would be highly undesirable.

JFK Assassination

Russell criticised the official account of the assassination of John F. Kennedy in "16 Questions on the Assassination", 1964. He was thanked in the acknowledgements section of Mark Lane's book Rush to Judgment for being "kind enough to read the manuscript and make suggestions", and after Simon & Schuster had declined to publish the book, Russell attempted to convince them otherwise. He also served as President of the British Who Killed Kennedy? Committee, in Russell's words the organisation was set up "for the purpose of making known the material [Lane] has uncovered and his further findings".

He is also thanked in Jim Garrison's On the Trail of the Assassins for "his early encouragement of my efforts".

Russell condemned the Warren Report as a "sorrily incompetent document" and said "it is clear that much is still being hidden". He argued that there were a number of "disturbing anomalies" regarding the assassination and that the Warren Commission had failed to deal with these doubts, that it instead "evades the facts". He believed that medical evidence had been altered and that "three contradictory official versions" had been put out.

China

In 1922 Russell visited China and remarked that "China, by her resources and her population, is capable of being the greatest power in the world after the United States".

Israel

Before the creation of the state of Israel, Russell expressed his support for Zionism. However, after its establishment, Russell would criticise the state of Israel on several occasions. On 31 January 1970, Russell issued a statement condemning "Israel's aggression in the Middle East", and in particular, Israeli bombing raids being carried out deep in Egyptian territory as part of the War of Attrition, which he compared to German bombing raids in the Battle of Britain and the US bombing of Vietnam. He called for an Israeli withdrawal to the pre-Six-Day War borders. This was Russell's final political statement or act. It was read out at the International Conference of Parliamentarians in Cairo on 3 February 1970, the day after his death.

He called for a "world campaign" to "help bring justice to the long-suffering people of the Middle East". He added that "No people anywhere in the world would accept being expelled en masse from their own country; how can anyone require the people of Palestine to accept a punishment that nobody else would tolerate?".

Eugenics

Russell discussed eugenics heavily in his 1929 book Marriage and Morals. He expressed agreement with the basic idea, while criticizing specific views and positions eugenicists held (particularly a strong class bias). Russell accepted a forced sterilization policy for negative eugenics, but only that of "mental defectives", condemning some laws for being overly broad. He also cautioned that eugenics policies had to account for scientific evidence, such as not making claims that all criminal behavior had genetic causes when psychology indicated otherwise. In terms of positive eugenics, he felt that free education should be provided for only to the professional classes, based not on the merits of the children, but of the parents, so that children do not suffer from cramming for scholarship examinations, which causes physical and mental damage. Russell also acknowledge the difficulty of deciding what desirable traits are, and that tradeoffs can exist (e.g. to breed for strength might diminish intelligence). He also acknowledged that to practice eugenics would entail a radical disruption of the family, feeling that a select group from the population might be set apart solely to breed in the future. While finding this idea repugnant, he thought it might nonetheless be effective. Discussing "race" eugenics, he felt the prevalent racist views were largely an excuse for chauvinism, and dismissed concerns about white people being outbred by East Asians. He considered some peoples inferior due to "environmental conditioning". He felt that in the future people might well select sexual partners for procreation voluntarily due to eugenic considerations. Russell felt certain eugenics views would win out in the future and become law. He conceded that it was repugnant to people and a "scientific tyranny" could arise, but felt this would be better than religious tyranny.

However, Russell also frequently stated his deep concern that eugenics would be used for political ends, rather than to improve humanity, stating, for instance, in a 1963 letter to eugenics proponent Julian Huxley, "Exceptional merit is, and always has been, disliked by Authority; and obviously Authority would control the sperm-bank. [...] I am entirely with you as to what eugenics could achieve, but I disagree as to what it would achieve.". This attitude also led to him supporting sterilisation of the "feebleminded", as he felt it, compared to the alternative of committal to an institution, preserved the ability of the sterilised to participate in society, and thus guarded against the possibility that a government would label its political opponents as "feebleminded" to silence them. He also expressed scepticism about the claims contemporary eugenicists made about the influence of heredity, such as in his 1932 book Education and the Social Order where he stated that the "practical inferences" drawn by eugenicists were unscientific due to the lack of knowledge about which traits were hereditary.

Personal life

In 1889, Russell, aged 17, met the family of Alys Pearsall Smith, an American Quaker five years his senior and a graduate of Bryn Mawr College near Philadelphia. He became a friend of the Pearsall Smith family. They knew him as "Lord John's grandson" and enjoyed showing him off.

He fell in love with Alys, and contrary to his grandmother's wishes, married her on 13 December 1894. Their marriage began to fall apart in 1901 when it occurred to Russell, while cycling, that he no longer loved her. She asked him if he loved her, and he factually replied that he did not. Russell also disliked Alys's mother, finding her controlling and cruel. A lengthy period of separation began in 1911 with Russell's affair with Lady Ottoline Morrell, and he and Alys finally divorced in 1921 to enable Russell to remarry. During his years of separation from Alys, Russell had affairs (often simultaneous) with a number of women, including Morrell and the actress Lady Constance Malleson. Some have suggested that at this point he had an affair with Vivienne Haigh-Wood, the English governess and writer, and first wife of T. S. Eliot.

In 1921, his second marriage was to Dora Winifred Black (died 1986), daughter of Sir Frederick Black. Dora was six months pregnant when the couple returned to England. The marriage was dissolved in 1935, having produced two children:

John Conrad Russell, 4th Earl Russell (1921–1987)

Lady Katharine Jane Russell (1923–2021), who married Rev. Charles Tait in 1948 and had issue

Additionally, Russell was temporarily registered as the birth father of Dora Russell's daughter, Harriett Ruth Barry (1930-2024), but this was reversed at some point and Harriett's father was correctly registered as American journalist Griffin Barry. Dora Russell also gave birth to a son by Griffin Barry in 1932, Roderick Barry (1932-1983). Though the Russell marriage was an open one, the Barry children's births led to a dissolution of the marriage and Russell divorced Dora. Russell did continue to be involved in both Barry children's lives, though not closely.

Russell's third marriage was to his student Patricia Helen Spence (d. 2004) in 1936, with the marriage producing one child:

Legacy

In 1980, a memorial to Russell was commissioned by a committee including the philosopher A. J. Ayer. It consists of a bust of Russell in Red Lion Square in London sculpted by Marcelle Quinton.

Lady Katharine Jane Tait, Russell's daughter, founded the Bertrand Russell Society in 1974 to preserve and understand his work. It publishes the Bertrand Russell Society Bulletin, holds meetings and awards prizes for scholarship, including the Bertrand Russell Society Award. She also authored several essays about her father; as well as a book, My Father, Bertrand Russell, which was published in 1975. All members receive Russell: The Journal of Bertrand Russell Studies.

For the sesquicentennial of his birth, in May 2022, McMaster University's Bertrand Russell Archive, the university's largest and most heavily used research collection, organised both a physical and virtual exhibition on Russell's anti-nuclear stance in the post-war era, Scientists for Peace: the Russell-Einstein Manifesto and the Pugwash Conference, which included the earliest version of the Russell–Einstein Manifesto. The Bertrand Russell Peace Foundation held a commemoration at Conway Hall in Red Lion Square, London, on 18 May, the anniversary of his birth.

Bangladesh's first leader, Mujibur Rahman, named his youngest son Sheikh Russel in honour of Bertrand Russell.

Awards and honors

Upon his brother's death in 1931, Russell became the 3rd Earl Russell of Kingston Russell, and the subsidiary title of Viscount Amberley of Amberley and of Ardsalla. He held both titles, and the accompanying seat in the House of Lords, until his death in 1970.
