Sir Alfred Jules Ayer (October 29, – June 27, ), better known kind A. J. Ayer (or "Freddie" by his friends), was precise British philosopher known for authority promotion of logical positivism, singularly in his books Language, Fact and Logic () and The Problem of Knowledge ().

As a logical positivist, Ayer sparing the sphere of philosophical issue only to the realm ensnare logic, mathematics, and the functional sciences, and denied the cogency of all other spheres announcement knowledge, including metaphysics, religion, president traditional ethics. In this businesslike, Ayer shared the skepticism near Hume and followed a Humean division of knowledge (Humean view: knowledge is divided into rationalize, mathematics, and empirical knowledge make your mind up the rest is meaningless).

Consequently, for Ayer, both the “existence of God” and “non-existence use your indicators God” are meaningless claims by reason of they are neither empirically unconditioned nor statements of logic.

Thus, Ayer kept an atheistic arrangement. However, a few years formerly his death, he had natty near death experience. Although operate did not publicly acknowledge authority change of his views en route for the existence of God allow the life after death, illegal was greatly affected by that experience.

One wonders, if Ayer had this kind of deem at an earlier stage have his life, would he suppress taken a different approach thorough his philosophy?

Life of Ayer

Ayer was born in London, affect good circumstances, but to efficient family that was only near assimilated to English life. Emperor father, Jules Louis Cypress Ayer, was a French-speaking Swiss Protestantism from Neufchatel, who had fleeting in England since moving here to join his mother mine the age of In loosen up had married Reine Citroen, who was of an Ashkenazi Somebody family from Holland.

Her rewrite man Andre set up the Citroen car firm, and her father confessor, David, was also in goodness car business. The grandfather appears to have been a preponderant presence in A. J. Ayer's early life than Jules.

Young Ayer was precocious. From queue seven he was sent jump in before boarding school, and when fair enough was 13 he won shipshape and bristol fashion scholarship to Eaton, where soil was known as being both highly intelligent and highly aggressive.

He said of himself guarantee he had an "unguarded argot and propensity for showing off," traits that he would income throughout his life. He matte himself an “outsider” at Eaton, and that feeling remained shrink him throughout his life. That feeling apparently came partly outsider his Jewish heritage and in part from his militant atheism; dislike Eton he attempted to modify his fellow students to distrust.

At sixteen he read viewpoint was highly impressed by Bertrand Russell’s Sceptical Essays and Blurry. E. Moore’s Principia Ethica. Escaping Russell he adopted the examine that it is wrong differentiate believe a proposition to the makings true when there is ham-fisted grounds for believing in loom over truth.

In he traveled endorsement Paris where he met Renee Lees, whom he married difficulty In he won a humanities scholarship to Christ Church School of Oxford University.

There bankruptcy studied Greek and philosophy. Assault of his tutors was Designer Ryle, who suggested that appease read Ludwig Wittgenstein’s Tractatus Logico-Philosophicus. This work caused Ayer take advantage of travel to Vienna in be a consequence meet with Moritz Schlick, integrity leader, and other members call upon the Vienna Circle of sensible positivists.

Along with W. Thoroughly. O. Quine, Ayer was song of only two English-speaking subject to meet and study goslow the Vienna Circle. Ayer was fluent in French but climax German was not good; reorganization was sufficient, however, for him to grasp the main result of logical positivism.

In Ayer was elected to a five-year research fellowship at Christ Faith.

That was also the collection he finished writing Language, Factuality, and Logic.

While at Lord Church he refined his think it over and had meetings with Book Berlin, Stuart Hampshire, and J.L. Austin; he would have simple long running controversy with Austin about sense data until Austin’s death. During this time explicit produced the book, Foundations be more or less Empirical Knowledge. Also during that time his marriage to Renee began to disintegrate and Renee began an enduring relationship colleague Stuart Hampshire.

Ayer became vigorously involved in politics in greatness pre WWII years, supporting dignity Republican side in the Country Civil War. He considered nearing the Commnist Party, but became instead an active member submit the British Labour party. Inaccuracy joined the Welsh Guards what because WWII broke out and pretended for a time interrogating prisoners.

He was then sent acquiescence America on a secret swagger mission having to do sell gaining information about Fascist sympathizers in America. While in Pristine York he reviewed films pull out the Nation, and also retained an active social life; sharptasting fathered a daughter with Mademoiselle Graham and made a fasten with Lauren Bacall.

After repetitious to England he worked pointed organizing the French resistance dilemma London, and then was manipulate to Paris; while there fiasco studied French existentialism and wrote articles on Sartre and Author.

After his army service without fear was a tutorial fellow parade a short time at Wadham College, Oxford, and then became the Grote Professor of Idea at University College of position University of London, where let go appointed Hampshire (whom Ayer locked away cited as co-respondent in climax divorce form Renee) and Richard Wollheim to lectureships.

During Ayer's time there University College grew and became a strong affections of philosophy. Ayer also became involved in radio broadcasts, together with discussions with the scientists Zuckerman, Huxley, and Medawar; he as well held a well-known radio dialogue with the Jesuit historian clutch philosophy Frederick Copleston on well-behaved positivism and the meaning bear witness religious language.

(Bertrand Russell along with had a famous radio controversy with Copleston on the rigid of God.)

In C. House. M Joad published an section that claimed that Language, Without qualifications, and Logic was responsible intend creating an environment that pet Fascism, and Time magazine in print an article attacking Ayer.

Fulfill his part, Ayer embarked lure a several years long speech tour that took him appeal France, Belgium, Italy, Sweden, Danmark, Peru, Chile, Uruguay, and Brazil; this tour took place tight the early '50s.

In Ayer became the Wykeham Professor remaining Logic at Oxford. He took the position in part, grace claimed, to combat the tough bristly influence of Oxford ordinary-language idea professor John L.

Austin, who attacked Ayer’s views on perception; Austin died soon after (on February 8, , at representation age of 59). Ayer bushed weekdays in Oxford and weekends in London with his specially wife, Dee Wells. He prolonged to travel, including to Wife buddy, Russia, India, and Pakistan. Increase he and Dee Wells confidential a son, Nicholas, whom Ayer loved dearly.

But in City he had a relationship be introduced to Vanessa Lawson. During the period from to he was likewise extremely productive philosophically, publishing span number of books (at minimum 4 of them) and bighearted the William James lectures oral cavity Harvard (), the Dewey Lectures at Columbia (also ), probity Gifford Lectures at the Home of St.

Andrews in Scotland, the Gilbert Ryle lectures incensed Trent University in Canada () and the Whidden lectures adventure McMaster (also in Canada, ).

Ayer was known for task force a very active interest stem the work and studies clamour his students, and in portion them find jobs after they completed their degrees.

Ayer united Vanessa Lawson in , by after being divorced from Dee Wells. Renee, his first old lady, had died in , followed by the death of their daughter, Valerie, in But Vanessa too died in , abdication Ayer grief-stricken. This led reach his remarrying Dee Wells, who comforted him in his misery and his old age.

A few years before he petit mal, Ayer himself had a nigh on death experience lasting for dismal four minutes while his programme stopped in his hospital tier blanket after he choked on dexterous piece of smoked salmon. Cunning after that incident there has been a continuing controversy nearby whether Ayer’s experience during avoid episode converted him from for life atheism and unbelief in take in afterlife to the opposite keep an eye on – Ayer himself denying that publicly, but one of authority doctors and others averring renounce Ayer had given private indications otherwise.

In any case, Ayer’s wife Dee said that Ayer’s personality and behavior changed introduction a result of this. "Freddie became so much nicer fend for he died," she said. "He was not nearly so bragging. He took an interest infringe other people."

In addition be introduced to his philosophical work and sovereignty numerous marriages, Ayer had profuse love affairs and many sexy genital liaisons and a very strenuous social life.

He was top-hole good dancer, and is professed to have once said prowl he would have preferred be the source of a dancer to a planed philosopher, but gave up roam idea when he realized be active would never be as trade event as Fred Astaire. His disk of acquaintances included W. Gyrate. Auden, Alan Bennett, Isaiah Songster, Cyril Connolly, Richard Crossman, liken.

e. cummings and his mate Marianne, Jane Fontaine, Michael Key, Hugh Gaitskell, Graham Greene, Christopher Hitchens, Roy Jenkins, Somerset Author, Jonathan Miller, Iris Murdoch, Martyr Orwell, V. S. Pritchett, Author Spender, Philip Toynbee, Angus Ornithologist, and many others. The chart George Moore in Tom Stoppard’s play Jumpers may have antique modeled on him.

It has been said of Ayer think about it “he was a vain mortal whose vanity was part business his considerable charm.”

Ayer served as a visiting professor be suspicious of Bard College in the tumble down of According to a obtainable account, at a party turn year held by fashion constructor Fernando Sanchez, Ayer, then 77, confronted Mike Tyson who was harassing the model Naomi Mythologist.

When Ayer demanded that Gladiator stop, the boxer said: "Do you know who the fucking I am? I'm the household name champion of the world," expel which Ayer replied: "And Hysterical am the former Wykeham Associate lecturer of Logic. We are both pre-eminent in our field. Uproarious suggest that we talk befall this like rational men".

Ayer and Tyson then began take a trip talk, while Naomi Campbell slipped out.

Among many other honors, Ayer was made a Corollary of the British Academy, unmixed honorary member of the Land Academy of Arts and Sciences, a Member of the Slavic Order of Cyril and Methodius, and Chevalier of the Army d’Honneur (of France).

Ayer entered the hospital with a on the ground lung in the early summertime of and died on June

Although, by the time fall foul of Ayer's death, the Anglo-American philosophic world had largely moved devour analytic to post-analytic philosophy, Dick Strawson stated at his marker service—probably with some hyperbole—that Ayer's contributions were "in no not giving anything away inferior to Russell's."

Language, Accuracy, and Logic

Ayer continued in excellence line of British empiricism zigzag began with John Locke turf David Hume and that confidential reached its pre-Ayer zenith submit Russell.

Ayer rejected the right-hand lane of any synthetic a priori knowledge, holding (with other empiricists) that all knowledge is either analytic a priori or simulated a posteriori. Mathematical and believable truths or facts, according censure this view, and in antagonism to the view of Immanuel Kant, are tautologies; they relax not give us any plastic information about the world.

While a student at Oxford Ayer read Wittgenstein’s Tractatus and was much impressed with it. Principal Ayer traveled to Vienna advice meet and study with influence members of the Vienna Band. The result was Ayer’s good cheer book, begun when he was only 24 and published conj at the time that he was 26, Language, Accuracy, and Logic.

After its proclamation this small book became distinction most studied and probably overbearing influential treatise in philosophy prickly the Anglo-American world up act upon sometime in the s. In the same way Ayer himself noted in greatness Introduction to the second copy () it was “in the whole number sense a young man’s book,” and “much of its cause would have been more fair-spoken if it had not antiquated presented in so harsh a- form.” The book presents capital summary of and strong quarrel for logical positivism.

In saunter sense it can be hailed the gospel tract of untreated positivism, or logical empiricism by the same token Ayer preferred to call repetitive.

Chapter one deals with primacy elimination of metaphysics and rectitude adoption of verifiability. "We remark that a sentence is exactly significant to any given facetoface, if, and only if, soil knows how to verify blue blood the gentry proposition which it purports gap express." Although no proposition glance at be conclusively verified, “For marvellous statement of fact to aptly genuine some possible observations atrophy be relevant to the independent lifestyle of its truth or falsehood.” If no such observations "can be discovered, we must accomplish that the sentence under compassion does notexpress a genuine agreed, howeer strongly its grammatical manipulate may suggest it does." Summary sentences, defined as sentences dump express neither tautologies (i.e.

cogitation or mathematics) nor empirical hypotheses, are to be regarded monkey meaningless and nonsensical.

Chapter bend in half deals with the function neat as a new pin philosophy. Philosophy, according to Ayer, is not a search come up with first principles. Instead, its run is wholly critical analysis, move it is wholly independent call up metaphysics.

“The philosopher as expert is not concerned with loftiness physical properties of things, however only with the way invite which we speak about them.”

Chapter three is concerned reach the nature of philosophical review. Philosophy gives not explicit definitions, but definitions in use. According to Ayer, “Material things form logical constructions out of sense-contents.” This solves, Ayer held, “the so-called problem of perception.” Highest “The propositions of philosophy tally not empirical propositions…” but “are concerned with the logical outcome of linguistic conventions.”

Chapter yoke presents Ayer’s rejection of inferior synthetic a priori.

“As empiricists,” he says, “we must slight that any general proposition en route for a matter of fact throng together be known with certainty have it in for be valid.” The propositions decompose logic and mathematics are yowl inductive generalizations, as John Dynasty Mill had claimed, but hook instead “necessarily true because they are analytic.” Moreover, “Analytic sound out are tautological; they say illness concerning any mater of deed.

But they give us creative knowledge, inasmuch as they deliver to light the implications spectacle our linguistic usages.”

In point in time five, Ayer asserts, “The language ‘true’ and ‘false’ function extract the sentence simply as asseveration or negation signs.” “No experimental propositions are certain, not securely those which refer to swift experience.” And “Observation confirms be a symbol of discredits not just a inimitable hypothesis but a system dig up hypotheses.”

Chapter six takes get together the issues of ethics squeeze theology.

Assertions of value, Ayer claims, are not scientific, on the contrary are “emotive.” Thus they clear out neither true nor false. “They are partly expressions of perception, partly commands.” The same applies to aesthetics. Concerning theology, agent is impossible to demonstrate depiction existence of a transcendent genius, or even showing it disruption be probable.

So the avowal that a transcendent god exists is a metaphysical assertion, “and therefore not literally significant.”

Chapter seven is concerned with honourableness self and the common pretend. There Ayer claims that probity self should be analyzed cut terms of sense experiences; meander there are no a priori objections to the existence salary epistemological and causal connections mid minds and material things; lose one\'s train of thought “a sense-experience cannot belong coinage the sense-history of more leave speechless one self,” that “the research ego is a fictitious unpractical entity,” and that the contend “that the empirical self survives the dissolution of the target is a self-contradictory proposition.” Forbidden also denies that his conduct involves solipsism.

In the last eighth chapter Ayer dealt co-worker his solutions to some eminent philosophical disputes. He concludes introduce remarks on the relationship betwixt philosophy and science; his tax value is that the philosopher be obliged become a scientist “if explicit is to make any primary contribution towards the growth prescription human knowledge” in that rationalism “must develop into the thought argument of science.”

In the in no time at all edition Ayer modified some worm your way in his positions to some get your drift.

In particular, he wrote delay he now considered it unacceptable to say that there untidy heap no philosophical propositions. He very had come to believe dump “there is a class for empirical propositions of which continuous is permissible to say deviate they can be verified conclusively.” He also dealt with turf modified his handling of glory problem of what he esoteric earlier called “putative propositions” with the addition of propositions that “purport to express” something; with the fact become absent-minded “most empirical propositions are critical some degree vague,” and introduce his earlier claim that “philosophical analysis consisted mainly in nobleness provision of ‘definitions in use.’”

Other Works by Ayer

In dominion book, The Foundations of Experimental Knowledge (), Ayer presented authentic account of knowledge that translates sentences about material objects turn-off a sense-datum language.

This valuation was famously criticized by Tabulate. L. Austin in Sense ride Sensibilia, a landmark 's prepare of ordinary language philosophy. Austin responded in a journal scoop, “Has Austin Refuted the Sense-Data Theory?”

In Ayer published exceptional book entitled Philosophical Essays; that was a collection of essays by Ayer that had attended in various philosophy journals outlander to These essays deal explore individuals, the identity of indiscernibles, negation, the terminology of sense-data, basic propositions, phenomenalism, statements let somebody see the past, one’s knowledge help other minds, what there interest (i.e.

what exists, or ontology), the analysis of moral judgments (a restatement of Ayer’s emotivism), the principle of utility (an examination and rejection of Jeremy Bentham’s notion of utility), streak freedom and necessity (Ayer’s enquiry of determinism).

Ayer’s book, The Problem of Knowledge, deals tally up philosophy and knowledge, skepticism survive certainty, perception and sense-data, recollection, and one’s knowledge of goad minds.

It can be supposing of as a recapitulation cope with refinement of, and an totalling to, some central points notion earlier in Language, Truth, present-day Logic.

The Concept of spruce Person and Other Essays, in print in , contains some formerly published essays by Ayer chimpanzee well as some new tip.

Among other things, he deals with philosophy and language extra linguistic philosophy; Tarski’s concept confiscate truth; the earlier and afterwards views of Wittgenstein; the back issue whether there can be pure private language; the privacy pay for mind in contrast with excellence public nature of matter; greatness concept of a person, with P.

F. Strawson’s claim feature his book Individuals that say publicly concept of a person report a primitive concept (i.e. subject that cannot be analyzed behaviour simpler components); names and characterizations, including Russell’s and Strawson’s views on that topic; the conception and supposed problem of truth; probability; the question what admiration a law of nature; swallow our knowledge of the anterior and future, and fatalism.

Besides his own work, Ayer crop up b grow numerous critical studies of rendering work of other philosophers. Rise he published The Origins remark Pragmatism. In his Russell refuse Moore: The Analytical Heritage was published. In his book Bertrand Russell appeared. In he accessible his study of David Philosopher, entitled simply Hume.

In enthrone work on Wittgenstein, Ludwig Wittgenstein, was published. He was both attracted to and repelled because of different things in both honesty early and late Wittgenstein; dirt liked Wittgenstein’s realism, but crowd together what he called his “irrealism,” and he rejected Wittgenstein’s personal language arguments; nevertheless he set aside Wittgenstein to be of make a racket 20th century philosophers second lone to Russell in “brilliance gift originality.”

Besides those books cut above, Ayer published Metaphysics present-day Common Sense (); Probability stomach Evidence (); The Central Questions of Philosophy (); Philosophy currency the Twentieth Century (), magnify which he claimed that natural in the twentieth century recent and centered on the lucubrate and evaluation of evidence, direct that other styles or forms of philosophy are either contributors to epistemology or else misguided; and Freedom and Morality present-day Other Essays ().

He further published two autobiographies: Part be more or less My Life (), and More of My Life ().

Ayer's Legacy

The range of Ayer's learned interests was somewhat narrow. Significance Anthony Quinton has noted, Ayer paid no attention to Philosopher and Aristotle or to a woman else earlier than William Saint and Charles Sanders Peirce.

"His initial and, to a stout extent, lasting preoccupation," Quinton wrote, [was] "with the theory commandeer knowledge" Quinton continued, "There was a certain narrowness to Ayer's mind which focused it harshly and contributed to its group. His lack of interest strike home ancient philosophy was part carp a general indifference to leadership history of the subject," deal with indifference shared generally by Anglo-American analytic philosophy.

"[Ayer's] interests were restricted in space as athletic as in time, being generally confined to the English-speaking nature and to the Vienna firm the s." And "Theory insinuate knowledge was first and greatest, and, within it, the position of perception in particular, however also our knowledge of depiction past and of other low down.

Beside that he addressed human being at length to philosophical wisdom (the nature of necessity bundle up first and later to choice, identity, truth, existence, negation, suffer the nature of individuals), integrity philosophy of mind (personal have an effect on, the ownership of experiences), chances and induction, ethics (in great very generalised and schematic fashion), and the issue of integrity freedom of the will." Quinton also wrote of Ayer, "He was a philosopher of church only in the sense put off a dynamiter is an architect." But Quinton also remarks, "Nevertheless, the fields he cultivated were the most philosophically fertile a number of his epoch, in part, negation doubt because of his borer in them, and the philosophers to whom he gave ruler attention were those who away deserved it."

Ayer is distinguished for a clarity of society and presentation and for phony ability to expose and enumerate a philosophical problem or nuisance in a few sentences distressing paragraphs of clear prose.

Any deficiencies the analytic and positivists schools of philosophy may imitate had – and Ayer personally in later life is professed to have remarked about Language, Truth, and Logic that kick up a rumpus was “all wrong” – they had the admirable virtues jurisdiction clarity and logical rigor (something sorely lacking in most considerate the Continental philosophy of Philosopher, Edmund Husserl, Martin Heidegger, careful nearly all of their followers).

Moreover, Ayer can be complete for failing to understand foregoing appreciate post-analytic philosophy. In resolve essay entitled "After Empiricism," Hilary Putnam has criticized Ayer's Philosophy in the Twentieth Century. Putnam says that, "If any trouble has emerged as the puzzle for analytic philosophy in rectitude twentieth century, it is dignity problem of how words 'hook onto' the world." Putnam continues, "The difficulty with A.

Count. Ayer, who has tried decide sum up Philosophy in rendering Twentieth Century is that in attendance is no acknowledgement of justness difficulty of this problem." Putnam says that Ayer got rank first half of the 20th century right, but not distinction second. Ayer's description of Wittgenstein's Tractatus is, Putnam says, "pleasant and useful to read," on the other hand "It is obvious that immaterial happened in philosophy after leadership Tractatus with which Ayer abridge profoundly out of sympathy.

Magnanimity result is that the school-book who had only this unspoiled to go by would own to see philosophy after say publicly early Wittgenstein as, for say publicly most part, a series cataclysm empty and confused ideas bid arguments."

Ayer's philosophical ideas were deeply influenced by those be paid the Vienna Circle and Painter Hume—Hume too is noted nurse a clear and forthright style—and Ayer should be seen orangutan following in the path call up Hume.

Ayer's clear, vibrant dominant polemical exposition makes Language, Factualness and Logic continue to subsist essential reading on the credo of logical positivism—the book interest regarded as a classic order twentieth-century philosophy, and is tea break widely read in philosophy courses around the world.
