I read Ernst Gombrich’s wonderful book Art and Illusion in 1981. I’d completed my BA a few months earlier, and I was spending a year in Geneva on a scholarship, before returning to Oxford to begin the BPhil. The topic in philosophy that interested me most at that time was perception, and I was struck by the extent to which Gombrich’s arguments relied on views about visual perception that he had inherited from the Helmholtzian tradition in psychology, and therefore indirectly (...) from Locke and Kant. I thought that arguments in the philosophy of perception exposed serious mistakes and confusions in this tradition, and that they could therefore shed important light on the fascinating questions about pictorial art that Gombrich discussed in his book.

John Hyman explores central problems in philosophy of action and the theory of knowledge, and connects these areas of enquiry in a new way. His approach to the dimensions of human action culminates in an original analysis of the relation between knowledge and rational behaviour, which provides the foundation for a new theory of knowledge itself.

A popular approach to defining fictive utterance says that, necessarily, it is intended to produce imagining. I shall argue that this is not falsified by the fact that some fictive utterances are intended to be believed, or are non-accidentally true. That this is so becomes apparent given a proper understanding of the relation of what one imagines to one's belief set. In light of this understanding, I shall then argue that being intended to produce imagining is sufficient for fictive utterance (...) as well. (shrink)

I shall be mainly concerned with the question ‘What is personal propositional knowledge?’. This question is obviously quite narrowly focused, in three respects. In the first place, there is impersonal as well as personal knowledge. Second, a distinction is often drawn between propositional knowledge and practical knowledge. And third, as well as asking what knowledge is, it is also possible to ask whether and how knowledge of various kinds can be acquired: causal knowledge, a priori knowledge, moral knowledge, and so (...) on. I shall dwell briefly on each of these three points. First, there is the distinction between personal and impersonal knowledge – in other words, between the psychological concept of knowledge and the social one.1 We use the concept of knowledge to describe the cognitive condition of individuals; but we also use it to describe the progress of scientific and historical research. So for example we can speak or enquire about the state of knowledge in a particular field of biology or history. And if we do so, we are evidently not concerned with what anyone in particular knows about, say, the genetics of fruit flies or the career of Charlemagne, but rather with what the scientific or academic community knows. Needless to say, there is a close connection between personal and impersonal knowledge. But ‘It is known that p’ does not simply mean ‘Someone or other. (shrink)

Professor Jessica Utts and I were given the task of evaluating the program on "Anomalous Mental Phenomena" carried out at SRI International (formerly the Stanford Research Institute) from 1973 through 1989 and continued at SAIC (Science Applications International Corporation) from 1992 through 1994. We were asked to evaluate this research in terms of its scientific value. We were also asked to comment on its potential utility for intelligence applications.

I am extremely grateful to all commentators for such patient, generous, and stimulating contributions. What follows are some thoughts to enrich the conversation, but these are by no means intended to be definitive answers to the worries they have raised.

Under what circumstances can we hold someone responsible for what they do?

“The longer you work, the more the mystery deepens of what appearance is, or how what is called appearance can be made in another medium."—Francis Bacon, painter This, in a nutshell, is the central problem in the theory of art. It has fascinated philosophers from Plato to Wittgenstein. And it fascinates artists and art historians, who have always drawn extensively on philosophical ideas about language and representation, and on ideas about vision and the visible world that have deep philosophical roots. (...) John Hyman’s _The Objective Eye_ is a radical treatment of this problem, deeply informed by the history of philosophy and science, but entirely fresh. The questions tackled here are fundamental ones: Is our experience of color an illusion? How does the metaphysical status of colors differ from that of shapes? What is the difference between a picture and a written text? Why are some pictures said to be more realistic than others? Is it because they are especially truthful or, on the contrary, because they deceive the eye? _The Objective Eye_ explores the fundamental concepts we use constantly in our most innocent thoughts and conversations about art, as well as in the most sophisticated art theory. The book progresses from pure philosophy to applied philosophy and ranges from the metaphysics of color to Renaissance perspective, from anatomy in ancient Greece to impressionism in nineteenth-century France. Philosophers, art historians, and students of the arts will find _The Objective Eye_ challenging and absorbing. (shrink)

theory of knowledge defended in Timothy Williamson's book Knowledge and its Limits is compared here with the theory defended in the author's articles ‘How Knowledge Works ’ and ‘ Knowledge and Self- Knowledge ’. It is argued that there are affinities between these theories, but that the latter has considerably more explanatory power.

This is a short preface to an edited collection, 'Agency and Action'.

Human agency has four irreducibly different dimensions -- psychological, ethical, intellectual, and physical -- which the traditional idea of a will tended to conflate. Twentieth-century philosophers criticized the idea that acts are caused by 'willing' or 'volition', but the study of human action continued to be governed by a tendency to equate these dimensions of agency, or to reduce one to another. Cutting across the branches of philosophy, from logic and epistemology to ethics and jurisprudence, Action, Knowledge, and Will defends (...) comprehensive theories of action and knowledge, and shows how thinking about agency in four dimensions deepens our understanding of human conduct and its causes.

This article explores the place of truth and truthfulness in painting and drawing, and criticises logocentrism in the theory of truth.

Presenting an engaging critique of current criminal justice practice in the UK and USA, this book introduces central questions of criminal law theory. It develops a forceful argument that the prevailing justifications for punishment are misguided, and have resulted in the systematic infliction of unnecessary human misery.

I argue that itches, tickles, aches and pains—sensations of all sorts—are generally in the places where we say they are. So, for example, if I say that I have an itch in the big toe on my left foot, then, by and large, that is the very place where the itch is. James denied this in the 1890s; Russell and Broad denied it in the 1920s; Wittgenstein and Ryle denied it in the 1940s; Lewis and Armstrong denied it in the (...) 1960s; and since then various kinds of materialists have denied it. But if itches etc. are states of the sensitive parts of bodies, then it is true. (shrink)

I discuss Timothy Willliamson’s conjecture that ‘knowing is the most general factive stative attitude, that which one has to a proposition if one has any factive stative attitude to it at all’.

Suitable for the teaching of medieval philosophy, this title features judicious selections and translations based on critical editions.

Many of today's ads work by arousing the viewer's emotions. Although emotion-arousing ads are widely used and are commonly thought to be effective, their careless use produces a side-effect: the psychoactive ad. A psychoactive ad is any emotion-arousing ad that can cause a meaningful, well-defined group of viewers to feel extremely anxious, to feel hostile toward others, or to feel a loss of self-esteem. We argue that, because some ill-conceived psychoactive ads can cause harm, ethical issues must arise during their (...) production. Current pretesting methods cannot identify the potentially psychoactive ads; therefore, we offer some tentative guidelines for reducing the number of viewers harmed by psychoactive ads. (shrink)

In this article, I oppose the view that knowledge is a species of belief, and argue that belief should be defined in terms of knowledge, instead of the other way round. However, I reject the idea that the concept of knowledge has a primary or basic role or position in our system of mental and logical concepts, because I reject the hierarchical conception of philosophical analysis implicit in this idea. I approach the topic of knowledge and belief from a discussion (...) of Richard Holton’s views about facts and factive verbs. (shrink)
