Ismael traces our sense that the past is fixed and the future open to what she calls ‘the practical arrow’ – ‘the sense that we can affect the future but not the past.’ In this piece I draw a sharper distinction than Ismael herself does between agents and mere observers, even self-referential observers; and I use it to argue that Ismael’s explanation of the practical arrow is incomplete. To explain our inability to affect the past we need to appeal to (...) our own temporal orientation as agents, and not merely to the ingredients from physics that allow us to predict the consequences of our actions. [This piece is a commentary on J Ismael’s ‘The Open Universe: Totality, Self-Reference and Time’, to appear in the Australasian Philosophical Review.]. (shrink)

This paper argues how boards of directors of three Icelandic oil companies were kept in the dark while the companies were collaborating in illegal competitive behaviour. The paper offers a unique view into a situation where information or lack thereof has played a key part in corporate governance, exploring the relationship between management and the board of directors and how information filtering can go wrong to the extent that vital information does not reach the board. The paper is based on (...) a case study of the illegal collaboration of the oil companies. It furthermore surveys the literature on information flow and information asymmetry for explanations of what happened in the case of the Icelandic oil companies. (shrink)

How do rational minds make contact with the world? The empiricist tradition sees a gap between mind and world, and takes sensory experience, fallible as it is, to provide our only bridge across that gap. In its crudest form, for example, the traditional idea is that our minds consult an inner realm of sensory experience, which provides us with evidence about the nature of external reality. Notoriously, however, it turns out to be far from clear that there is any viable (...) conception of experience which allows it to do the job. The original problem is to show that thought is rationally constrained by external reality. If sensory experience is to provide the solution--in particular, if it is to provide the answer to sceptical challenges--it must therefore meet two criteria. First, it must itself be `receptive'--i.e., appropriately constrained by external reality. Second, it must be the kind of thing that can enter into a logical or rational relationship with belief--it must already be `conceptual,' in other words. In arguing against the idea that anything could serve both roles, Wilfred Sellars termed this conception of experience "the Myth of the Given.". (shrink)

Some things, but only some things, are by nature subject to standards. Why? I explain and develop what I call nature-first constitutivism, which says that what something is determines what it should be. Nature is the basis of normativity. I explain this view in terms of a unique type of property which particulars of a genus can lack even though those properties partially determines the nature of the genus. Such properties partially describe the nature of a genus and are thereby (...) normative for the particulars of that genus. Particulars of genera with such essential properties are by nature subject to standards with respect to those properties. Particulars of genera without such properties are not by nature subject to standards. (shrink)

Does artificial intelligence (AI) pose existential risks to humanity? Some critics feel this question is getting too much attention, and want to push it aside in favour of conversations about the immediate risks of AI. These critics now include the journal Nature, where a recent editorial urges us to 'stop talking about tomorrow's AI doomsday when AI poses risks today.' We argue that this is a serious failure of judgement, on Nature's part. In science, as in everyday life, we expect (...) influential actors to consider the consequences of error. As the world's leading scientific journal, Nature is certainly an influential actor, especially so in the absence of robust global regulation of AI. Yet it has manifestly failed to consider the cost of error in this case. (shrink)

What explains why we are subjects for whom objects can have value, and what explains which objects have value for us? Axiologicians say that the value of humanity is the answer. I argue that our value, no matter what it is like, cannot perform this task. We are animals among others. An explanation of the value of objects for us must fit into an explanation of the value of objects for animals generally. Different objects have value for different animals. Those (...) differences depend on differences in animal natures and, in particular, on the diverse characteristic capacities of different animals. Once we invoke animal natures, there is nothing for the value of animality, including the value of humanity, to explain. (shrink)

Intellectualism is the widespread view that practical reason is a species of theoretical reason, distinguished from others by its objects: reasons to act. I argue that if practical reason is a species of theoretical reason, practical judgments by nature have nothing to do with action. If they have nothing to do with action, I cannot act from my representation of reasons for me to act. If I cannot act from those representations, those reasons cannot exist. If they cannot exist, neither (...) can a species of theoretical reason about them. Intellectualism is thus self-undermining. (shrink)

Properly understood, the instrumental rule says to take means that actually suffice for my end, not, as is nearly universally assumed, to intend means that I believe are necessary for my end. This alternative explains everything the standard interpretation can—and more, including grounding certain correctness conditions for exercises of our will unexplained by the standard interpretation.

Practical cognitivism is the view that practical reason is our will, not an intellectual capacity whose exercises can influence those of our will. If practical reason is our will, thoughts about how I am to act have an essential tie to action. They are intentions. Thoughts about how others are to act, though, lack such a tie to action. They are beliefs, not intentions. How, then, can these thoughts form a unified class? I reject two answers which deny the differences (...) between such thoughts about myself and those about others, one of which says that all such thoughts are intentions, the other that all are beliefs. I then reject a shared assumption which says that a class of thoughts is unified only if all its elements are all of one type of thought. I instead argue that this class is unified even though some elements are intentions, others beliefs, because such beliefs depend on those intentions in various ways. (shrink)

Practical cognitivism is the view that practical reason is the self-conscious will and that practical cognition is self-conscious volition. This essay addresses two puzzles for practical cognitivism. In akratic action, I act as I understand is illegitimate and not as I understand is legitimate. In permissible action, I act as I understand is legitimate and also do not act as I understand is legitimate. In both types of action, practical cognition seems to come apart from volition. How, then, can practical (...) reason be our will and practical cognition be volition? Practical cognitivists can solve these puzzles because the claims that practical reason is our will and that practical cognition is volition are about the nature of a capacity, and the nature of a capacity establishes standards of correctness for its exercises. Akratic action is a type of erroneous exercise of practical reason as tripping is an erroneous exercise our capacity to walk. Permissible action is a successful exercise of practical reason as stepping first with my right foot rather than my left is a successful exercise of my capacity to walk. The puzzles of akratic and permissible action do not refute practical cognitivism. (shrink)

argues that the success of the backward causation hypothesis in quantum mechanics would provide strong support for a version of Reichenbach's account of the direction of causal processes, which takes the direction of causation to rest on the fork asymmetry. He also criticises my perspectival account of the direction of causation, which takes causal asymmetry to be a projection of our own temporal asymmetry as agents. In this reply I take issue with Dowe's argument at three main points: his claim (...) that the backward causation hypothesis in QM is incompatible with my perspectival approach to the direction of causation; his defence of the fork asymmetry approach against a general criticism of mine based on the time-symmetry of microphysics; and his application of his preferred account of the direction of causal processes to the relevant cases in QM.

In this paper, I try to develop an account of functions which might be of use to a biologist engaged in classifying and explaining natural phenomena. The most pressing difficulty facing such an account is the need to reconcile the normativity of function statements with their explanatory force. I consider two familiar accounts of function statements, offered by Andrew Woodfield and Larry Wright . I examine both accounts in search of the strongest possible formulation of each type of theory. I (...) fail to find a formulation of the ACT which is completely immune from counterexamples, but I do find a satisfactory formulation of the HT. In particular, I argue that the HT should incorporate a point central to the ACT that functions involve a means/end relationship between two devices. I then consider functional explanations: I argue that an ACT which holds that function statements are intrinsically explanatory cannot offer a satisfactory account. The account offered by Woodfield, who rejects this assumption, is adequate, though less attractive than the account suggested by the HT. I conclude by considering how the HT can account for functional norms. (shrink)

Reports of phantom limbs amongst aplasics have often been presented as evidence that body image is ‘hard-wired’ in the brain and that neither sensory input nor proprioceptive feedback are essential to its formation. Although attempts have been made to account for these phantoms by other means, these have been on a case by case basis and no satisfactory alternative framework has been proposed. This paper collates the accounts of aplasic phantoms and presents them as compatible with a four-part hypothesis, in (...) which body image is learnt from experience during both pre- and post-natal development, and in which cross-cortical connections and mirror neurons play prominent roles. This model unites several previously disparate theories to offer a viable solution to several longstanding phantom limb mysteries and serves to highlight avenues worthy of further inquiry. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy of Music Education Review 12.1 (2004) 30-42 [Access article in PDF] How Can Music Seem to be Emotional? Kingsley Price Johns Hopkins University Preliminary Let me make some preliminary remarks about my question. First, the distinction employed in it, the distinction between seeming and reality, comes in two forms. The first is inclusive. A thing that really is so-and-so also seems to be so-and-so. The butler really (...) is guilty and seems guilty as well. The second is exclusive. A thing that is really not so-and-so seems to be so-and-so. The butler is really not guilty but seems to be guilty. The distinction that underlies my question is of the exclusive form.Second, the music I ask about is not music as read from scores on paper or held in memory. Nor is it music that contains linguistic elements-words or gestures as in song, opera, ballet, etc. Rather, it is purely instrumental music, and that as perceived or heard.Third, the emotions I refer to are not physiological conditions that may cause them, nor the behavior that may express them, but the conscious feelings we find in ourselves when we are undergoing emotion. [End Page 30] The Problem Persons (perhaps even the lower animals) can seem to be, without really being, emotional. They are pretending, or we perceive mistakenly. There is no difficulty, in principle, in explaining the situation. But there would be if they were sculptured persons only-that is, if they could not possibly be emotional. A sculpture cannot seem to be emotional by pretending it; nor can we perceive mistakenly that it is emotional when we know that it is a sculpture only.Much music is like sculpture. Not personal, we know that it cannot really be emotional. None-the-less, we hear the wedding march from Mendelssohn's music for A Midsummer Night's Dream as joyful, the second movement of Chopin's Sonata in B-flat Minor as sorrowful, "The Great Fugue" as grimly resigned, the first movement of the first Razumowski as hopeful, etc. How can this be so? How can music seem to be emotional?I look for an answer to this question, first, within the perception, the hearing of music, and then, without it in its meaning. If seeming emotionality is found in either place, I shall have answered the question. And now, for the first place. The Perception In sense perception there are two major constituents.1 One is awareness; the other is the object of awareness. Awareness occurs in all the kinds of consciousness-in remembering, imagining, dreaming, and thinking, for example, as well as in sense perception. In this last, it is brought about by operation of the senses; while in the others, that operation plays no direct part. But although it differs in its cause, awareness in sense perception is precisely the same, considered in itself, as it is in all the other kinds of consciousness, considered in themselves.What is awareness? It cannot be explained, as many notions can, by eliciting its parts. To understand what squareness is, for example, we need only bring forward the parts that constitute it: four straight lines equal in length, four right angles, and closed plane figure. But awareness has no parts and cannot be explained in this way. To call attention to its simplicity and its identity in all kinds of consciousness, indeed, is all that can be done to explain it though we might add the simile that likens awareness to the light that brings things before our minds out of the dark that conceals them in its absence.Now, hearing is a kind of sense perception-the kind that occurs by virtue of operation of the auditory organs; and music heard is one of the objects of auditory awareness. Can we understand how this object can seem to be emotional by appeal to the awareness of it? If that awareness seemed to exist and did not really do so, the answer would be that we cannot since the awareness of it... (shrink)

Citizens' juries are commended as a new technique for democratising health service reviews. Their usefulness is said to derive from a reliance on citizens' rational deliberation rather than on the immediate preferences of the consumer. The author questions the assertion of critical detachment and asks whether juries do in fact employ reason as a means of resolving fundamental disagreements about service provision. He shows that juries promote not so much a critically detached point of view as a particular evaluative framework (...) suited to the bureaucratic idiom of social welfare maximisation. Reports of jury practice reveal a tendency among juries to suppress by non-rational means the everyday moral language of health care evaluation and substitute for it a system of thought in which it can be deemed permissible to deny treatment to sick people. The author concludes that juries are chiefly concerned with non-rational persuasion and because of this they are morally and democratically irrelevant. Juries are no substitute for voting when it comes to protecting the public from zealous minorities. (shrink)

Is the exemplar of modern ethical theory estranged from their intimates because the motive of duty dominates their motivational psychology? While this challenge against modern ethical theory is familiar, I argue that with respect to a certain strand of Kantian ethical theory, it does not so much as make sense. I explain the content and functional role of the motive of duty in the psychology of the moral exemplar, stressing in particular how that motive shapes and informs the content of (...) others, including those characteristic of intimacy. I argue that to the extent that a subject does not integrate their motive of duty with their other motives, their moral and intimate relationships are compromised, and on the same grounds, because intimate relationships are interpersonal relationships and the motive of duty just is the motive to respect another person as a separate person.

This volume brings together fourteen major essays by one of contemporary philosophy's most challenging thinkers. Huw Price links themes from Quine, Carnap, Wittgenstein and Rorty, to craft a powerful critique of contemporary naturalistic metaphysics. He offers a new positive program for philosophy, cast from a pragmatist mould.

Pragmatists have traditionally been enemies of representationalism but friends of naturalism, when naturalism is understood to pertain to human subjects, in the sense of Hume and Nietzsche. In this volume Huw Price presents his distinctive version of this traditional combination, as delivered in his René Descartes Lectures at Tilburg University in 2008. Price contrasts his view with other contemporary forms of philosophical naturalism, comparing it with other pragmatist and neo-pragmatist views such as those of Robert Brandom and Simon (...) Blackburn. Linking their different 'expressivist' programmes, Price argues for a radical global expressivism that combines key elements from both. With Paul Horwich and Michael Williams, Brandom and Blackburn respond to Price in new essays. Price replies in the closing essay, emphasising links between his views and those of Wilfrid Sellars. The volume will be of great interest to advanced students of philosophy of language and metaphysics. (shrink)

The subject of my lecture is an appropriate one for several reasons. The first is purely chronological. Hume's first and greatest work, the Treatise of Human Nature, was published in 1739, two hundred years ago. Its illustrious author was then quite unknown in the world, and as he tells us himself the book “fell dead-born from the press.” But by the end of the eighteenth century its reputation was securely established, and it has long been regarded as one of the (...) masterpieces of European thought, and as the classical statement of the Empiricist Philosophy. It is true that, like other classics, it has had its ups and downs. During the Absolute Idealist period, which ended early in the present century, Hume was the great bogey-man, and the duty of all self-respecting philosophers was to refute him. In our own day things are different. Empiricism, despite many obituary notices, is very much alive again. And this time it is in close alliance with Natural Science, and has equipped itself with all the technique of modern Symbolic Logic; it is more vigorous in construction and more formidable in criticism than it has ever been before. Consequently Hume is no longer the bogey-man. People now read the Treatise not as an awful warning, but as a source of stimulus and illumination. Incidentally, we can now enjoy his admirable style without any qualms. It is no longer thought that if a philosopher writes in clear and entertaining English, what he writes must therefore be either superficial or false. We regard obscurity and turgidity as demerits, not as signs of profound thinking. Moreover, we have learned to appreciate the eighteenth century, of which Hume was one of the most characteristic products. (shrink)

Understanding recreational experiences is a longstanding research tradition and key to effective management. Given the complexities of human experience, many approaches have been applied to study recreational experience. Two such approaches are the experiential approach (based in a positivistic paradigm) and emergent experience (based in an interpretive paradigm). While viewed as being complementary, researchers have not offered guidance for incorporating the approaches into a common model of recreational experience. This study utilized longitudinal, qualitative data to examine aspects of recreational experience (...) posited by these two approaches. Results provided a framework for synthesizing across the two approaches. Respondents had clear pre-activity expectations, and most respondents realized their expected outcomes. This supports the experiential approach. Of the 48 activity narratives, 27 experienced something unexpected, and 45 described process-oriented, intrinsic motivation, suggesting evidence of emergent and unique characteristics specific to an individual’s realization of recreational experience. This supports the application of the emergent experience approach to understand how individuals create meaning from recreational engagements. The paper proposes a model for integrating results of the two approaches. While not advocating for any specific approach, the findings can serve as an example of building a holistic model of the outdoor recreation experience. The purpose of the model is to allow for a more complete understanding of how individuals create recreation experiences, more complete documentation of the benefits of outdoor recreation for both researchers and managers, and better synthesis across studies.

How, in pursuit of ontological neutrality, should one talk about values? I propose to say: there are values. Those three words do nothing to define within what kind of conception of a world values are at home.1 I take it that the ‘realist’ must have more to say about values and their world. I recognize that an ‘anti-realist’ may prefer to talk of value-terms ; I ask him to wait and see whether taking the linguistic turn is the only way (...) to put values in their place. (shrink)

Originally published in Mexico in 1970, _Indigenous and Popular Thinking in América _is the first book by the Argentine philosopher Rodolfo Kusch to be translated into English. At its core is a binary created by colonization and the devaluation of indigenous practices and cosmologies: an opposition between the technologies and rationalities of European modernity and the popular mode of thinking, which is deeply tied to Indian ways of knowing and being. Arguing that this binary cuts through América, Kusch seeks to (...) identify and recover the indigenous and popular way of thinking, which he contends is dismissed or misunderstood by many urban Argentines, including leftist intellectuals. _Indigenous and Popular Thinking in América_ is a record of Kusch's attempt to immerse himself in the indigenous ways of knowing and being. At first glance, his methodology resembles ethnography. He speaks with and observes indigenous people and mestizos in Peru, Bolivia, and Argentina. He questions them about their agricultural practices and economic decisions; he observes rituals; he asks women in the market the meaning of indigenous talismans; he interviews shamans; he describes the spatial arrangement and the contents of shrines, altars, and temples; and he reproduces diagrams of archaeological sites, which he then interprets at length. Yet he does not present a "them" to a putative "us." Instead, he offers an inroad to a way of thinking and being that does not follow the logic or fit into the categories of Western social science and philosophy. In his introduction, Walter D. Mignolo discusses Kusch's work and its relation to that of other twentieth-century intellectuals, Argentine history, and contemporary scholarship on the subaltern and decoloniality. (shrink)

In this paper we defend the view that the ordinary notions of cause and effect have a direct and essential connection with our ability to intervene in the world as agents.1 This is a well known but rather unpopular philosophical approach to causation, often called the manipulability theory. In the interests of brevity and accuracy, we prefer to call it the agency theory.2 Thus the central thesis of an agency account of causation is something like this: an event A is (...) a cause of a distinct event B just in case bringing about the occurrence of A would be an effective means by which a free agent could bring about the occurrence of B. In our view the unpopularity of the agency approach to causation may be traced to two factors. The first is a failure to appreciate certain distinctive advantages that this approach has over its various rivals. We have drawn attention to some of these advantages elsewhere, and we summarize below. However, the second and more important factor is the influence of a number of stock objections, objections that seem to have persuaded many philosophers that agency accounts face insuperable obstacles. In this paper we want to show that these objections have been vastly overrated. There are four main objections. (shrink)

The founder of Psychical Research, though he has not yet received the honour due to him, seems to have been King Croesus of Lydia, who reigned from 560 to 546 B.C. He carried out an interesting experiment, recorded in detail by Herodotus,2 to test the clairvoyant powers of a number of oracles. He sent embassies to seven oracles, six Greek and one Egyptian. They all started on the same day. On the hundredth day each embassy was instructed to ask its (...) oracle, “What is King Croesus, the son of Alyattes, now doing?” The answer was to be written down and brought back. The oracle of Delphi replied as follows, in hexameters, as its custom was: “I know the number of the sands and the measures of the sea. I understand the dumb, and I hear him who does not speak.” Then it went on: “There comes to my mind the smell of a strong-shelled tortoise, which is being cooked along with lamb's flesh in a brazen vessel; brass is spread beneath it, and with brass it is covered.” As a matter of fact, this answer was perfectly correct. Herodotus tells us that “having considered what would be the most difficult thing to discover and to imagine,” Croesus “cut up a tortoise and a lamb, and himself boiled them together in a brazen pot.” What happened afterwards illustrates the difficulties of this sort of investigation, difficulties which still perplex us to this day. Croesus argued, reasonably enough, that if the Delphic priestess had clairvoyant powers, she probably also had the precognitive powers, she probably also had the precognitive powers which she claimed to have. But when he consulted the oracle later about his forthcoming expedition against the Persians, he received two answers, one of which was ambiguous—“When Croesus crosses the Halys he shall destroy a great empire”—and the other correct, but too obscure to be easily interpreted.

Is non-cognitivism compatible with minimalism about truth? A contemporary argument claims not, and therefore that moral realists, for example, should take heart from the popularity of semantic minimalism. The same is said to apply to cognitivism about other topics—conditionals, for example—for the argument depends only on the fact that ordinary usage applies the notions of truth and falsity to utterances of the kind in question. Given this much, minimalism about truth is said to leave no room for the view that (...) the utterances concerned are non-cognitive in nature. (shrink)

This book explores for the first time an idea common to both Plato and Aristotle: although people are separate, their lives need not be; one person's life may overflow into another's, so that helping someone else is a way of serving oneself. Price considers how this idea unites the philosophers' treatments of love and friendship (which are otherwise very different), and demonstrates that this view of love and friendship, applied not only to personal relationships, but also to the household (...) and even the city-state, promises to resolve the old dichotomy between egoism and altruism.

This paper discusses the relation between Crispin Wright’s alethic pluralism and my global expressivism. I argue that on many topics Wright’s own view counts as expressivism in my sense, but that truth itself is a striking exception. Unlike me, Wright never seems to countenance an expressivist account of truth, though the materials needed are available to him in his approaches to other topics.

In this adventurous contribution to the project of combining philosophy and biology to understand the mind, Carolyn Price investigates what it means to say that mental states--like thoughts, wishes, and perceptual experiences--are about things in the natural world. Her insight into this deep philosophical problem offers a novel teleological account of intentional content, grounded in and shaped by a carefully constructed theory of functions. Along the way she defends her view from recent objections to teleological theories and indicates how (...) it might be applied to notable problems in the philosophy of mind. (shrink)

The Wall Street Journal article “Putting a Price on a Human Egg” triggered extensive media coverage of a rather unusual challenge to payments made to women providing ova for use in assisted reproduction. In Kamakahi v. American Society for Reproductive Medicine and Society for Assisted Reproductive Technologies, plaintiffs claim that ASRM and SART policies adopting limits on such payments violate the federal antitrust prohibition against price fixing.In 2007, an ASRM Ethics Committee Report, confirming a 2000 report, asserted (...) that, “[a]lthough there is no consensus on the precise payment that oocyte donors should receive, at this time sums of $5,000 or more require justification and sums above $10,000 are not appropriate.” SART is an affiliate organization of ASRM and counts as its members 90 percent of the clinics providing assisted reproductive technologies in the United States. SART requires that its members “[adhere] to all ASRM/SART Guidelines including ethical, practice, advertising, and laboratory.” The plaintiffs in Kamakahi claim that the agreement among SART members to abide by the ASRM policy restricts competition among agencies procuring oocytes and produces lower payments than women would otherwise be able to negotiate. It is through the requirement that SART members adhere to ASRM ethical guidelines that ethics goes to market and encounters antitrust law. Ethicists continue to debate whether payment for oocytes inappropriately commodifies the human body, and ASRM policy consistently refers to their procurement as the “donation process” and to women who participate as “donors.” Nevertheless, in the context of antitrust law, the procurement of oocytes is a business and clearly falls within the reach of antitrust restrictions on business conduct.

To appear in David Chalmers, Ryan Wasserman and David Manley, eds., Metametaphysics (OUP, 2009).

This article contributes to the debate around the abilities of large language models such as GPT-3, dealing with: firstly, evaluating how well GPT does in the Turing Test, secondly the limits of such models, especially their tendency to generate falsehoods, and thirdly the social consequences of the problems these models have with truth-telling. We start by formalising the recently proposed notion of reversible questions, which Floridi & Chiriatti propose allow one to ‘identify the nature of the source of their answers’, (...) as a probabilistic measure based on Item Response Theory from psychometrics. Following a critical assessment of the methodology which led previous scholars to dismiss GPT’s abilities, we argue against claims that GPT-3 completely lacks semantic ability. Using ideas of compression, priming, distributional semantics and semantic webs we offer our own theory of the limits of large language models like GPT-3, and argue that GPT can competently engage in various semantic tasks. The real reason GPT’s answers seem senseless being that truth-telling is not amongst them. We claim that these kinds of models cannot be forced into producing only true continuation, but rather to maximise their objective function they strategize to be plausible instead of truthful. This, we moreover claim, can hijack our intuitive capacity to evaluate the accuracy of its outputs. Finally, we show how this analysis predicts that a widespread adoption of language generators as tools for writing could result in permanent pollution of our informational ecosystem with massive amounts of very plausible but often untrue texts.

Philosophy, like modern agriculture, is a little too prone to monoculture. Happily, unpopular philosophical traditions are less in danger of complete extinction than varieties of apple, say, or breeds of pig. For this difference, however, the subject is often indebted to a few far-sighted individuals who appreciate the value of presently unfashionable ideas – who stand ready to reinvigorate the gene pool, when popular approaches succumb to pests and inbreeding.

The subject of this paper is the relation of Logical Positivism to Theology. By “Logical Positivism” I mean the doctrine originated by Dr. Wittgenstein and expounded more at length by Professors Carnap, Schlick, and other members of the Viennese Circle in the periodical called Erkenntnis . The clearest account of it in English is that given by Mr. R. B. Braithwaite in the volume called Cambridge University Studies.

Professor Ayer's lecture is not only a most auspicious inauguration; it is also an important contribution to philosophy. It is perhaps the best and the most exciting work he has written, and that is saying a good deal. There is a certain theory about thought and its objects which is often hinted at in the utterances and the writings of contemporary empiricist philosophers, but so far as I know it has never before been stated in print. Mr. Ayer has stated (...) it, clearly and in detail, with all his well-known force and felicity of style. It is a strange and rather shocking theory, very different from the one which most philosophers hitherto have believed. But if we are shocked by it, the shock will be salutary. The dragon has at last come clearly into view. If we resolve to accustom ourselves to it and treat it kindly, we may hope that it will transform itself by degrees into a nice gentle domestic pet, as other philosophical dragons have before.

Many areas of philosophy employ a distinction between factual and non-factual (descriptive/non-descriptive, cognitive/non-cognitive, etc) uses of language. This book examines the various ways in which this distinction is normally drawn, argues that all are unsatisfactory, and suggests that the search for a sharp distinction is misconceived. The book develops an alternative approach, based on a novel theory of the function and origins of the concept of truth. The central hypothesis is that the main role of the normative notion of truth (...) is to encourage speakers to argue, with long-run behavioural advantages. This offers a fresh perspective on many debates about realism in contemporary philosophy. (shrink)
