A. J. Ayer

This paper reflects on an article that appeared after the death of A.J. Ayer, which complains about what British philosophers focus on. I propose that the content of the philosophy curriculum can be predicted from a rational actor model.

The aim of this paper is double. In the fi rst part I argue against the traditional interpretation of Ayer’s emotivism. According to this interpretation, in Language, Truth and Logic Ayer based emotivism on his “radical empiricist” view. I argue that this is not so. Then, in the second part I develop a new interpretation of emotivism according to which Ayer’s analysis of moral vocabulary does not depend on positivism. The purpose of the article is to contribute to the history (...) of metaethics by presenting a correct account of Ayer’s analysis. (shrink)

El cosmopolitismo es uno de los elementos fundamentales de la concepción de la justicia defendida por M.C. Nussbaum. Esta sería una de las tesis esenciales del presente ensayo. El enfoque de las capacidades (EC) defendido por ella pretende ser una alternativa a las modernas teorías del contrato. Para Nussbaum, dignidad, capacidades humanas y recursos materiales son indesligables. Del mismo modo, la perspectiva cosmopolita es una exigencia inexcusable en la teoría de la justicia de Nussbaum. En este artículo tratamos de rastrear (...) los distintos ingredientes de esta, sus raíces en el cosmopolitismo estoico, y también su discusión con él para afrontar los desafíos que plantea la justicia global en el presente, con una perspectiva de futuro.

A.J Ayer occupies an unusual and unique position in the history of twentieth century philosophy. He remains both famous and infamous. In England particularly, few philosophers are as well known outside academia; perhaps only Russell and Wittgenstein are more familiar to the general public than Ayer. And yet within philosophy, his work and legacy attract nothing like the respect or reverence of those peers. Ayer is well known amongst philosophers, but not so well thought of. Language, Truth and Logic, the (...) book that made his name and defines his legacy, is extraordinarily well known, easily available, and still features on many undergraduate syllabi, but is remembered primarily as a thrillingly brash failure. And as controversial as the content of LTL is its frequent use as the English language bible of Logical Empiricism (at least to scholars of the Vienna Circle). (shrink)

Ayer’s Language, Truth and Logic (1936) was immediately regarded as a clear and faithful presentation of the views of the Vienna Circle to English-speaking readers. Since Ayer wrote this book after his visit to Vienna, where he participated in the meetings of the Circle, one may often hear to this day that he brought logical positivism to England. However, while Ayer’s conception was a form of logical positivism, it significantly differed from its Viennese counterpart(s). The key discrepancies are related to (...) verificationism: this article aims to analyse these discrepancies. It will be claimed that upon his return from Vienna Ayer assumed positions that were no longer, or had never been, held in the Circle: regarding the verification principle, test-statements, phenomenalist reductionism and analyticity.

Here is a brief introduction to Ayer's radical criticism of religious belief. According to Ayer, a sentence like ‘God exists’ doesn't assert something false; rather, it fails to assert anything at all.

This is an updated version of an essay originally written for a special issue of Philosophical Topics on the links between Kant and analytic philosophy. It explores these links by focusing on: Wittgenstein’s Tractatus; the logical positivism endorsed by Ayer; and the (very different) variation on that theme endorsed by Quine. The claim defended is that in all three cases we see analytic philosophers trying to attain and express a general philosophical understanding of why the bounds of sense should be (...) drawn where they should—but thereby confronting the aporia, which Kant too confronted, that it is impossible to do this without transgressing those very bounds. The paper closes by suggesting that the problem is in trying to attain and express such an understanding; in other words, that such an understanding is attainable, but not expressible. (shrink)

Jacques Derrida resignificó el concepto de escritura, que pasó de describir la transliteración de la voz, a ser un fenómeno de inscripción de sentido previo a cualquier signo. Esta extensión conceptual es la base de la deconstrucción. En este artículo se analizan los planteamientos centrales del proyecto filosófico de Derrida y se plantea una reflexión sobre el desenlace de la filosofía de la (archi)escritura en el contexto actual de la renovación de los nuevos materialismos y, en particular, el proyecto de (...)

In this essay I discuss the evolution of A. J. Ayer’s account of the mind-body relation through his career, with an emphasis on his early ideas. The reconstruction of Ayer’s ideas on this particular topic, beyond being interesting in itself, may also be illuminating inasmuch as it provides further details on the path Ayer carved out for himself within the large-scale development of analytic philosophy, progressing from the radical anti-metaphysicalism of the logical positivists in the 1930s towards the (re)birth of (...) analytic metaphysics in the 1960s. Ayer’s philosophical development may be divided into two major periods characterized by a comprehensive phenomenalist and a “sophisticated realist” approach. In the phenomenalist period, Ayer regarded the question of whether sense-data are mental or physical nonsensical, and he did not address the nature of the psychophysical relation either. After the realist turn, however, he did find these questions meaningful, and discussed them in detail. In LTL and other prominent works from the phenomenalist period, issues concerning the nature of mind, body and their relation were expounded primarily through linguistic analysis, i.e. by investigating the meaning of sentences reporting mental states of one’s own and of others as well as of perceptual reports. These investigations were framed by Ayer’s views on the privacy or publicity of sense-data and phenomenalistic language, which changed significantly several times. In laying out Ayer’s phenomenalism I also discuss his views on privacy in some detail. Furthermore, I briefly touch upon Ayer’s account of the psychophysical relation in the late realist period, which may be characterized by his trenchant “anti-physicalism”, and his wavering between a mere correlation view and a version of Russellian monism. These later views were laid out in the “sophisticated realist” framework and may be considered metaphysical, in contrast with Ayer’s earlier purely linguistic approach. -/- . (shrink)

The title is meant to indicate that consciousness is being examined largely within the history of philosophy, and within the period of time from Descartes to Ayer. Investigators aiming to understand consciousness and minds usually try to take account of all individual human minds, so as to have the most data for the most encompassing induction. The problem with that approach is that because of the vastness of the data, its results tend to be vague, lacking the specificity of studies (...) of individuals. On the other hand, the problem with studies of individuals is that they cannot guarantee generality, as the opposing method can. This book's distinctive approach aims at a middle way, getting the best of the two opposing methods by drawing its data from the history of philosophy, especially the history of the great philosophers.

A. J. Ayer’s empiricist criterion of meaning was supposed to have sorted all statements into nonsense on the one hand, and tautologies or genuinely factual statements on the other. Unfortunately for Ayer, it follows from classical logic that his criterion is trivial—it classifies all statements as either tautologies or genuinely factual, but none as nonsense. However, in this paper, I argue that Ayer’s criterion of meaning can be defended from classical proofs of its triviality by the adoption of a relevant (...) logic—an idea which is motivated because, according to Ayer, the genuinely factual statements are those which observation is relevant to.

The age-old question “What is truth?” is not an unambiguous one. There are at least two different meanings. In one sense, it is a semantic question about the meaning of the word “truth” and/or a metaphysical question about the nature of the property of truth, that is, how truth can be defined in terms of other notions, if it is definable at all. In another sense, it is an epistemological question about the criterion or test of truth, that is, how (...) we can recognize or accept (empirical) propositions as true. Ayer, in Language, Truth and Logic (LTL) and some other articles, tried to convince us that when we attempt to elucidate a theory of truth, we are only engaging in the epistemological project of finding the criterion of truth. This anti-semantical and anti-metaphysical view is based on Ayer’s (radical) deflationism about truth. In this chapter, I will argue that since Ayer did not accept that the criterion of truth is intimately related to the concept of truth, he can be seen as a deflationist about the nature of truth and as an advocate of a certain (Schlickian) kind of correspondence conception about the criterion of truth. His position would not be tenable if he had maintained what some of his contemporaries accepted, namely that there is a close connection between the two truth-theoretical tasks: the definitional and the criterial one.

The ‘between Wars’ period in England in the early twentieth century was extraordinary, philosophically. It was marked by a profusion of new, controversial, and revolutionary ideas. Developments in formal logic, the rise of the method of ‘analysis’, and logical atomism were already changing the face of philosophy in England. From this mix emerged two distinctive views about language and its connection to philosophical methodology: one championing the concept of an ideal language; and one rejecting this and favoring appeal to ordinary (...) language. The origin of both views is to be found in the (earlier and later) work of Ludwig Wittgenstein. In this paper, I will examine the emergence of these views in relation to one another: an ideal language conception represented by A.J. Ayer in his Language, Truth and Logic, and the reaction against this conception in the early phases of ordinary language philosophy, in particular in the work of John Wisdom. (shrink)

This essay takes the position, consistent with Ayer’s own retrospective judgments, that the philosophical significance of Language, Truth and Logic (LTL) was minimal at best, and that its real significance was socio-historical. LTL stands as one of the most influential expressions of an overzealous and simplistic scientism that swept through Western culture in the first half of the twentieth century. This scientism played a crucial role in problematizing the West’s relationship to truth in ways that contributed to the eventual emergence (...) of “post-truth” culture, with its “post-truth politics.” This in turn made possible the disastrous results of recent votes and elections in Britain and, above all, in the United States. In short, LTL’s real significance resides in the role it played as a sophisticated and successful bit of propaganda for an ideology that played a crucial role in loosing Western culture from its moral and epistemic moorings.

A. J. Ayer’s Language, Truth, and Logic had been responsible for introducing the Vienna Circle’s ideas, developed within a Germanophone framework, to an Anglophone readership. Inevitably, this migration from one context to another resulted in the alteration of some of the concepts being transmitted. Such alterations have served to facilitate a number of false impressions of Logical Empiricism from which recent scholarship still tries to recover. In this paper, I will attempt to point to the ways in which LTL has (...) helped to foster the various mistaken stereotypes about Logical Empiricism which were combined into the received view. I will begin by examining Ayer’s all too brief presentation of an Anglocentric lineage for his ideas. This lineage, as we shall see, simply omits the major 19th century Germanophone influences on the rise of analytic philosophy. The Germanophone ideas he presents are selectively introduced into an Anglophone context, and directed towards various concerns that arose within that context. I will focus on the differences between Carnap’s version of the overcoming of metaphysics, and Ayer’s reconfiguration into what he calls the elimination of metaphysics. Having discussed the above, I will very briefly outline the consequences that Ayer’s radicalisation of the Vienna Circle’s doctrines had on the subsequent Anglophone reception of Logical Empiricism.

The history of the relationship between science and metaphysics is riddled with controversy. Aristotle and his followers see metaphysics as providing the foundations on which science and other human intellectual endeavors build. In opposition to the thoughts of Aristotle, Plato and his followers separate metaphysics from science as independent and unrelated sciences. With the Logical positivists, the debate is a reject of metaphysics in favour of science. Metaphysics then is seen as a pseudo-science. Rudolf Carnap's the "Elimination of Metaphysics through (...) the Logical Analysis of Language" and Alfred Jules Ayer's elimination of metaphysics from the domain of knowledge are examined, while Heidegger is brought in to salvage the situation given that he holds on to the superiority of metaphysics over science. (shrink)

Ayer’s critique of Metaphysics is much indebted to Hume and Kant’s pioneering appraisals of metaphysics. Its uniqueness lies mainly in the attempt to ground the rejection of metaphysics on a linguistic basis rather than epistemic premise as Hume and Kant before him. Yet it remains to be seen whether Ayer’s initiative fares better than its predecessors in discrediting metaphysics.

The waning popularity of logical empiricism and the supposed discovery of insurmountable technical difficulties led most philosophers to abandon the project to formulate a formal criterion of empirical significance. Such a criterion would delineate claims that observation can confirm or disconfirm from those it cannot. Although early criteria were clearly inadequate, criticisms made of later, more sophisticated criteria were often indefensible or easily answered. Most importantly, Carnap’s last criterion was seriously misinterpreted and an amended version of it remains tenable.

Most analytic philosophers are atheists, but is there a deep connection between analytic philosophy and atheism? The paper argues a) that the founding fathers of analytic philosophy were mostly teenage atheists before they became philosophers; b) that analytic philosophy was invented partly because it was realized that the God-substitute provided by the previously fashionable philosophy - Absolute Idealism – could not cut the spiritual mustard; c) that analytic philosophy developed an unhealthy obsession with meaninglessness which led to a new kind (...) of atheism that dismissed talk of God as factually meaningless (neither true nor false) rather than meaningful but false; but d) that this new-fangled atheism (unlike the old-fashioned atheism of the founders) is false, since it relies on theories of meaning – verificationism and falsificationism – which are themselves false. The primary focus is on Bertrand Russell, though other analytic philosophers such as Ayer, Neurath and Flew are also extensively discussed. (shrink)

Twentieth-century philosophy has often been pictured as divided into two camps, analytic and continental. This study challenges this depiction by examining encounters between some of the leading representatives of either side. Starting with Husserl and Frege's fin-de-siècle turn against psychologism, it turns to Carnap's 1931 attack on Heidegger's metaphysics (together with its background in the Cassirer-Heidegger dispute of 1929), moving on to Ayer's 1951 meeting with Bataille and Merleau-Ponty at a Parisian bar, followed by the 'dialogue of the deaf' between (...) Oxford linguistic philosophers and phenomenologists at the 1951 Royaumont colloquium, leading up to the Derrida-Searle controversy. Careful study shows that it is implausible to assume the existence of a century-old 'gulf' between two sides of philosophy. Vrahimis argues that miscommunication and ignorance over the exact content of the above encounters must to a large extent be held accountable for any perceived gap. (shrink)

In his recent article, titled ‘Royaumont Revisited’, Overgaard challenges Dummett's view that one needs to go as far back as the late nineteenth century in order to discover examples of genuine dialogue between ‘analytic’ and ‘continental’ philosophy. Instead, Overgaard argues that in the 1958 Royaumont colloquium, generally judged as a failed attempt at communication between the two camps, one can find some elements which may be utilized towards re-establishing a dialogue between these two sides. Yet, emphasising this image of Royaumont (...) as a kind of battleground between ‘analytic’ and ‘continental’ philosophy obscures the plurality of philosophical approaches involved. Royaumont was the meeting point of more than two philosophical traditions, as can be shown by the divergent interests of its participants. Thus, though the potential for rapprochement between Oxford ‘linguistic philosophy’ and a certain strand of phenomenological thought may indeed be found among the discussions that took place during the colloquium, one should keep in mind that such rapprochement took place in the context of a meeting between, among others: continental ‘analytics’, Anglophone non-‘analytics’, French historians of philosophy, ‘analytic’ opponents of Oxford philosophy, Franciscan phenomenologists, and Oxonians who called their work ‘phenomenology’.

In contrast to many of his contemporaries, A. J. Ayer was an analytic philosopher who had sustained throughout his career some interest in developments in the work of his ‘continental’ peers. Ayer, who spoke French, held friendships with some important Parisian intellectuals, such as Camus, Bataille, Wahl and Merleau-Ponty. This paper examines the circumstances of a meeting between Ayer, Merleau-Ponty, Wahl, Ambrosino and Bataille, which took place in 1951 at some Parisian bar. The question under discussion during this meeting was (...) whether the sun existed before humans did, over which the various philosophers disagreed. This disagreement is tangled with a variety of issues, such as Ayer’s critique of Heidegger and Sartre, Ayer’s response to Merleau-Ponty’s critique of empiricism, and Bataille’s response to Sartre’s critique of his notion of ‘unknowing’, which uncannily resembles Ayer’s critique of Sartre. Amidst this tangle one finds Bataille’s statement that an ‘abyss’ separates English from French and German philosophy, the first recorded announcement of the analytic-continental divide in the twentieth century.

_Philosophical Delusion and its Therapy_ provides new foundations and methods for the revolutionary project of philosophical therapy pioneered by Ludwig Wittgenstein. The book vindicates this currently much-discussed project by reconstructing the genesis of important philosophical problems: With the help of concepts adapted from cognitive linguistics and cognitive psychology, the book analyses how philosophical reflection is shaped by pictures and metaphors we are not aware of employing and are prone to misapply. Through innovative case-studies on the genesis of classical problems about (...) the mind and perception, and on thinkers including Locke, Berkeley and Ayer, the book demonstrates how such autonomous habits of thought systematically generate unsound intuitions and philosophical delusions, whose clash with reality, or among each other, gives rise to ill-motivated but maddening problems. The book re-examines models of therapeutic philosophy, due to Wittgenstein and J. L. Austin, and develops an approach that may let us overcome philosophical delusions and the problems they engender. In this way, the book explains where and why therapy in called for in philosophy, and develops techniques to carry it out. (shrink)

Alfred Jules Ayer was born in London and educated at Eton and Christ Church, Oxford. He attended sessions of the logical positivist ‘Vienna Circle’ in 1932, and taught at Oxford from 1933 until joining the Army in 1940. His Language, Truth and Logic was published in 1936, and The Foundations of Empirical Knowledge in 1940. After war service he returned to Oxford in 1945, and became Grote Professor of the Philosophy of Mind and Logic at University College, London, the following (...) year. The Problem of Knowledge was published in 1956. In 1959 he returned to Oxord as Wykeham Professor of Logic, a post he held until his retirement in 1977. He had been made a Fellow of the British Academy in 1952, and was knighted in 1970. Among his publications after he returned to Oxford are The Concept of a Person , Philosophical Essays , The Origins of Pragmatism , Metaphysics and Common Sense , Russell and Moore: the Analytical Heritage , Probability and Evidence , The Central Questions of Philosophy , and Philosophy in the Twentieth Century.

El objetivo de este trabajo es presentar y examinar la teoría emotivista de los enunciados morales, según la versión de Alfred Ayer. En primer lugar, se estudian los antecedentes de esta teoría y se describe el ambiente positivista en el que surge. La teoría se expone prestando particular atención a los aspectos metaéticos y sus principales consecuencias. Finalmente, se propone que la teoría emotivista puede mantenerse con independencia y al margen del positivismo.

It is commonly assumed that the non-cognitivists of the first half of the twentieth century - the emotivists – were internalists about moral motivation. It is also commonly assumed that they were prompted to choose emotivism over other cognitivist positions in ethics because of their commitment to internalism. Finally, it is also commonly assumed that they used an internalist argument to argue for emotivism. -/- In this article I argue that the connection between emotivism and internalism is far more tenuous (...) than is commonly assumed. I focus on two of the most important and influential emotivists: A. J. Ayer and Charles L. Stevenson. While it is true that Stevenson was an internalist, Ayer refused to endorse internalism. Neither of them was originally prompted to choose emotivism over cognitivist positions in ethics by internalist considerations. Finally, Ayer never used an internalist argument to argue for emotivism; Stevenson did once borrow an internalist argument from another philosopher in order to argue for emotivism, but he later abandoned it.

The desire for parsimony – to posit as few explanatory features as possible – has a rich philosophical history and is often given lots of weight in philosophical theory construction. But, as the psychologist Tania Lombrozo has demonstrated, our bias in favour of parsimony can lead us to adopt simple explanations even when it’s far more likely that a complicated explanation is correct.

Ayer and Stevenson advocated ethical emotivisms, non-cognitivist understandings of the meanings of moral terms and functions of moral judgments. I argue that their reasons for ethical emotivisms suggestanalogous epistemological emotivisms. Epistemological emotivism importantly undercuts any epistemic support Ayer and Stevenson offered for ethical emotivism. This is because if epistemic emotivism is true, all epistemic judgments are neither true nor false so it is neither true nor false that anyone should accept ethical emotivism or is justified in believing it. Thus, their (...) perspectives are epistemologically self-undermining and, truthfully, should be rejected. Unlike Ayer and Stevenson, Gibbard explicitly endorses ethical and epistemological emotivism, or expressivism; I criticize his views in detail elsewhere. (shrink)

It was news verging on sensational when A. J. Ayer came back from four minutes of heart death with a report of what he saw. Especially since the philosopher, who publicized his near-death experience [NDE] in 1988, in the Telegraph and the Spectator, was known for his lifelong rejection of religion and the supernatural. But, as will be seen, Ayer's beliefs on that head were substantially unchanged, if more ambivalently expressed, and the interest of his NDE lies elsewhere— in what (...) it reveals about his philosophy.
