The Difference Between Deductive and Inductive Reasoning - Daniel Miessler
Ayer — was only 24 when he wrote the book that made his philosophical name, Language, Truth, and Logic hereafter LTLpublished in In it he put forward what were understood to be the major theses of logical positivism, and so established inductive essays as the leading English representative of the movement, Viennese in origin. In endorsing these views Ayer saw himself as continuing in the line of British empiricism established by John Locke and David Hume, inductive essays, an empiricism whose most recent representative was Bertrand Russell.
The major portion of his work was devoted to exploring different facets of our claims to inductive essays, particularly inductive essays knowledge and knowledge that depended on inductive inference for its credence. In LTL he put forward an emotivist theory of ethics, one inductive essays he never abandoned.
Ayer always wrote with stylish crispness and clarity; he could lay bare the bones of a philosophical difficulty in a few paragraphs of strikingly simple prose. On many a philosophical problem Ayer cannot be bettered for providing a lucid, informative, and revealing description of its contours. Above all, on reading an essay of his, whether it be on basic propositions, sense data, inductive essays, induction, or freedom, one comes away recognizing that the aim of the author has been to reach the truth, no matter what that turned out to be.
Unfortunately, he sometimes rushed to reach it, inductive essays, which, together with the directness of his style, gave him a reputation for mere cleverness that he never lived down. Nevertheless, amongst British philosophers of the 20 th Century he has been ranked as second only to Russell Foster ; P. Alfred Jules Ayer was born in London inductive essays October 29, His mother, Reine, was descended from Dutch Inductive essays, whilst his father, Jules Louis Cypress Ayer, inductive essays, came from a Swiss Calvinist background.
As recounted in RogersAyer was a precocious but mischievous child, and so was sent to boarding school outside Eastbourne at the age of seven, from which he won a scholarship to Eton in There he impressed his peers with his intelligence and competitiveness, the latter trait manifesting itself in the way he played games, inductive essays. At the age of sixteen he specialized in classics and at the same time started reading some philosophy.
Ayer said that this remained a motto for him throughout his philosophical career see Rogers At the same time a reading of G.
The Easter before leaving Eton, Ayer spent some time in Paris, where he met Renee Lees, whom he subsequently married in The following year he won a classics scholarship to Christ Church, Oxford, inductive essays, where he studied both Greek and philosophy, one of his tutors being Gilbert Ryle, inductive essays.
Ryle was also instrumental in getting Ayer to go to Vienna in to study with Moritz Schlick, then leader of the influential Vienna Circle of philosophers, scientists and other intellectuals, joining W. Quine in being one of only two visitors to be members of the Vienna Circle. His philosophical experience in Vienna was somewhat limited by his uncertain inductive essays of German, but he knew enough to pick up the basic tenets of logical positivism. After leaving Vienna, Ayer lectured for a short time at Christ Church, where in he was elected to a five-year research fellowship.
In the same year he finished LTLwhich caused a great deal of controversy and debate, partly for its sweeping dismissal of metaphysics, but especially for the metaethical emotivism Ayer championed in one of its most notorious chapters. During the next few years, Ayer worked at defending and refining some of the positions adopted in LTLnot least at meetings in Oxford with Isaiah Berlin, inductive essays, Stuart Hampshire, and J.
Austin; the confrontations with Austin were to prove long-lasting. The product of this refining process was the book Foundations of Empirical Inductive essays. During this time he also enjoyed life to the full; he was a good dancer, once confessing that he would have inductive essays to be a tap-dancer rather than a professional philosopher, but had given up on the idea when he recognized that he would never be as good as Fred Astaire.
His marriage to Renee started inductive essays disintegrate; Ayer had numerous affairs, and Renee formed an enduring relationship with Stuart Hampshire.
In the immediate pre-war years, inductive essays, Ayer had become passionate about politics. He supported the Republican side in Spain, flirted with joining the Communist Party, but instead became an active member of the Labour Party. When war inductive essays declared he joined the Welsh Guards and was helped to do so by Gilbert Ryle. He worked for a while in Cambridge interrogating prisoners, then was sent to America to join a secret service mission, one which seemed to involve gathering information about Fascist sympathizers in America.
Whilst in New York he reviewed films for the Nationfathered a daughter Sheila Graham was the motherand made a record with Lauren Bacall. On being repatriated to England, Ayer found himself given the job of helping with the organization of the French resistance movements in London. Shortly after the war he was posted to Paris, where he took the opportunity to study French existentialism, writing articles on Sartre and Camus in Horizon.
On his release from Army service Ayer accepted the offer of a tutorial fellowship at Wadham College, Oxford, but was there only a short while before becoming the Grote Professor of Philosophy at University College, London, at the age of He quickly appointed Hampshire to a lectureship making up for having cited Hampshire as co-respondent in his divorce from Reneethen Richard Wollheim.
The department grew and became a thriving philosophical center. Ayer also ventured into the world of radio, being involved in many BBC Third Programme broadcasts, including panel discussions with the scientists Zuckerman, Huxley and Medawar, and a famous debate with the Jesuit priest Frederick Copleston on the existence of God. In he lectured at Bard College in New York, but it proved to be an unhappy experience. Back in London C.
On his return to Europe he started a hectic schedule of lecture tours, visiting France, inductive essays, Belgium, Italy, Sweden, Denmark, Peru, Chile, Uruguay, and Brazil, all in the early s.
In Ayer took the opportunity to return to Oxford as Wykeham Professor of Logic. Not that it was completely sacrificed; he bi-located, spending long weekends in London with his second wife, Dee Wells, and at most three nights in New College during the week. He continued to travel widely: China, Russia, inductive essays, India, and Pakistan were added to the itinerary, inductive essays.
He also continued his political activity, continuing to support the Labour Party, campaigning against British involvement inductive essays Vietnam, and being at one time Vice-President of the Society for the Reform of the Abortion Law, Chairman of the Campaign Against Racial Discrimination in Sport, and President of the Homosexual Law Reform Society.
His support for the decriminalization of homosexual behavior, inductive essays, he once quipped, could not be thought by anyone acquainted with him to involve a vested interest. His support for the SDP was a protest at the leftward trend of the Labour Party, and particularly its anti-Europeanism. He formed a relationship with Vanessa Lawson, inductive essays, whom he would see whilst in Oxford.
During this time, Ayer inductive essays to be philosophically productive, inductive essays, doing some of his most original work. The Origins of Pragmatism was published infollowing this Russell and Moore: the Analytical Heritage the product of the William James lectures he delivered at Harvard inand Probability and Evidence the Dewey lectures inductive essays at Columbia University in Shortly thereafter came Russella small paperback, and The Central Inductive essays of Philosophyoriginally given as the Gifford Lectures at the University of St.
Andrewsin which he elaborated on the sophisticated realism first put forward in The Origins inductive essays Pragmatism. He visited Canada on a couple of occasions, giving the Gilbert Ryle lectures at Trent University resulting in his book on Hume, and the Whidden lectures at McMaster giving rise to Freedom and Morality. Shortly after being divorced from Dee Wells, Ayer married Vanessa Lawson in Tragically Vanessa was to die of liver cancer inleaving Ayer grief-stricken.
He moved quickly to dispel these rumours. He spent most of the remaining couple of years responding to articles that were to appear in the Ayer inductive essays in the Library of Living Philosophers series, edited by L. He remarried Dee Wells, inductive essays, but not long afterwards Ayer was admitted to hospital with a collapsed lung in the early summer of and died on the 27 thJune.
Ayer wrote two autobiographies, Part of My Lifeand More of My Life. His circle of friends included many famous and influential people; the following in no particular order is only a brief list. Cyril Connolly, Graham Greene, George Orwell, ee cummings and his wife Marianne, Meyer Schapiro, Arthur Koestler, Bertrand Russell, inductive essays, Stephen Inductive essays, W.
Auden, Philip Toynbee, inductive essays, Isaiah Berlin, Hugh Gaitskell, Roy Jenkins, Michael Foot, Richard Crossman, Jonathan Miller, inductive essays, Angus Wilson, Alan Bennett, Alice Thomas Ellis, Joan Fontaine, Iris Murdoch, V. Pritchett, and Christopher Hitchens. Ayer was a vain man whose vanity was part of his considerable charm, inductive essays. He made a distinction between vanity and egotism; an egotist, he said, inductive essays he should have more medals, whilst a vain person just enjoyed showing off the medals he had, inductive essays.
His first formulation of a criterion of meaning, inductive essays, the principle of verification, was in the first edition of LTLwhere he claimed that all propositions were analytic true in virtue of their meaning or else either strongly verifiable or weakly verifiable. Strong verification required that the truth of a proposition be conclusively ascertainable; weak verification required only that an observation statement be deducible from the proposition together with other, auxiliary, propositions, provided that the observation statement was not deducible from these auxiliaries alone.
So in the second edition Ayer amended the principle to read: a statement is directly verifiable if it is either an observation statement or is such that an observation statement is derivable from it in conjunction with another observation statement inductive essays observation statementssuch derivability not being possible from the conjoined observation statement s alone.
This principle generated further criticism, most significantly from Alonzo Churchwho claimed inductive essays show that, again, it allowed any statement to be meaningful. Take O 1O 2and O 3 as logically independent observation statements, and S any statement whatsoever. is directly verifiable, as 1 in conjunction with O 1 entails O 3, inductive essays. S becomes indirectly verifiable, as O 2 follows from S and 1and 1 is directly verifiable.
Despite the failure of these attempts to provide a rigorous empiricist criterion of meaning, Ayer continued to hold that there was a close connection between evidence and meaning, maintaining that a satisfactory account of confirmation was needed before a fool-proof criterion of empirical meaning could be supplied.
Given later doubts about whether any theory of confirmation could inductive essays a foundation for a theory of meaning Quinean doubts inductive essays to the impossibility of ruling out any facts as possibly bearing on the truth of any sentenceinductive essays, it remains unclear as to how the evidence-meaning connection can be circumscribed, inductive essays.
For a review of other attacks on, and adjustments to, the verification principle, see Wright It was the strong version that was used in his discussion of the meaning of sentences about the past and other minds, but in his discussion of the latter another inductive essays emerged.
The strong interpretation of the criterion required there to be some decision made as to what evidence contributed to the meaning of verifiable sentences. Further, although only present evidence is available to anybody making a statement about the past, the meaning of such a statement is not restricted to such present evidence; one is entitled to include in the meaning evidence that would be available if one were able to transport oneself to that past time.
This is examined again in Section 7. The only class of statements that Ayer allowed to be meaningful without such a connection to evidence was that comprised of tautologies, which included all analytic propositions. These were the only propositions knowable a prioritheir meaning being dependent on how language was used, and on the conventions governing that use. Ayer insisted that the necessity attaching to these propositions was only available once the conventions governing language-use were in play.
Similarly, inductive essays, when we say a proposition is probable, or probably true, we are not assigning any intrinsic property to the proposition, nor saying that there is any relation it bears to any other proposition.
We are simply expressing our confidence in that proposition, or, more accurately, it expresses the degree of confidence it is rational to possess in the proposition. This deflationary inductive essays to truth was supported by his verificationism about meaning; Ayer did not have to provide truth-conditions for the meaning of sentences. Assertions had meaning in virtue of their verification conditions, and propositions were defined just as an equivalence class of sentences with the same verification conditions.
Deflationism about truth replaces a concern for a substantial theory of truth with a concern about which sentences, inductive essays utterances, are deemed to be truth-apt, inductive essays. Ayer denied that moral utterances were truth-apt. Given that he thought that asserting that p was equivalent to saying that p was true, he had to deny that moral utterances could be assertions see section 7. See the entry on the deflationary theory of truth for further discussion.
These latter statements were the ultimate verifiers, forming the basis upon which our empirical world was constructed. His criticism of such views was that the favoured class of statements could not be picked out in the right way without an appeal to relevant experience.
So a criterion for membership of the favored class of statements that required only those statements accepted by the scientists of the time to be members of the class was not going to be successful without knowing which sentences were thus accepted, and this, Ayer claimed, could only be known by experience. The alternative of using yet another sentence, one stating that these pqr… were the sentences in the relevant class those accepted by the scientistswould make the foundations of science entirely arbitrary.
It was this continuing commitment to sense-data as the objects of perception that drew J. Once we have this theory, we are able reinterpret the quale as mental states and claim that they inductive essays caused by the physical objects.
This causal claim is only merited once the theoretical system is in inductive essays, and so cannot be a primitive element in any account of perception, inductive essays.
