Henry Sidgwick was one of the great intellectual figures of nineteenth-century Britain. He was first and foremost a great moral philosopher, whose masterwork The Methods of Ethics is still widely studied today. He also wrote on economics, politics, education and literature. He was deeply involved in the founding of the first college for women at the University of Cambridge. He was also much concerned with the sexual politics of his close friend John Addington Symonds, a pioneer of gay studies. Through (...) his famous student, G. E. Moore, a direct line can be traced from Sidgwick and his circle to the Bloomsbury group. Bart Schultz has written a magisterial overview of this great Victorian sage. This biography will be eagerly sought out by readers interested in philosophy, Victorian literary studies, the history of ideas, the history of psychology and gender and gay studies. (shrink)

This paper develops the basics of the theory of involutive categories and shows that such categories provide the natural setting in which to describe involutive monoids. It is shown how categories of Eilenberg-Moore algebras of involutive monads are involutive, with conjugation for modules and vector spaces as special case. A part of the so-called Gelfand–Naimark–Segal (GNS) construction is identified as an isomorphism of categories, relating states on involutive monoids and inner products. This correspondence exists in arbritrary involutive symmetric monoidal categories.

There can be good reasons to doubt the authority of a group of scientists. But those reasons do not include lack of unanimity among them. Indeed, holding science to a unanimity or near-unanimity standard has a pernicious effect on scientific deliberation, and on the transparency that is so crucial to the authority of science in a democracy. What authorizes a conclusion is the quality of the deliberation that produced it, which is enhanced by the presence of a non-dismissible minority. Scientists (...) can speak as one in more ways than one. We recommend a different sort of consensus that is partly substantive and partly procedural. It is a version of what Margaret Gilbert calls “joint acceptance” – we call it “deliberative acceptance.” It capitalizes on there being a persistent minority, and thereby encourages accurate reporting of the state of agreement and disagreement among deliberators.

Towards an account of character traits in self-Knowledge, With an assessment of the sartrean thesis ("spectatorism") that character trait concepts are fitted for other-Ascription rather than self-Ascription. The logic of ascriptions of evil character and specific vices is dealt with. The relationship of self-Ascription to self-Falsification and "seeing oneself as an object" is examined. Self-Ascription has peculiarities, But at most a very mild form of spectatorism is born out.

A 27000 word survey of Russell’s ethics for the SEP. I argue that Russell was a meta-ethicist of some significance. In the course of his long philosophical career, he canvassed most of the meta-ethical options that have dominated debate in the Twentieth and Twenty-First Centuries — naturalism, non-naturalism, emotivism and the error-theory (anticipating Stevenson and Ayer on the one hand and Mackie on the other), and even, to some extent, subjectivism and relativism. And though none of his theories quite worked (...) out, there is much to be learned from his mistakes. Nor is this all. His ARGUMENTS as well as his THEORIES are often interesting and instructive. The ethical corollary to the argument of ‘Seems Madam? Nay, It Is,’ puts the kybosh on any attempt to resolve Sidgwick's Dualism of Practical Reason by arguing that although we are distinct beings with different interests in the world of Appearance, we are, in Reality, all one (§3). Russell's arguments against objectivism are often quite powerful, and one anticipates Gilbert Harman's influential argument that objective values can be safely dismissed since they lack explanatory power (§9.3-9.4). Russell's damning critique of Moore's analytic consequentialism led Moore to abandon the view and perhaps to give up his ‘unduly anti-reforming’ moral conservatism. Moreover Russell's INDIRECT influence on meta-ethics may have been profound since the Open Question Argument, was probably invented to deal with Russell's ideas. Finally, in the realm of normative ethics, Russell developed a sensible and humane version of consequentialism, which (despite its shaky meta-ethical foundations) is resistant, if not immune, to many of the standard criticisms, especially if combined — as Russell thought it should be combined — with a healthy dose of political skepticism. It provides a powerful tool for social and political criticism, a tool which Russell vigorously employed on a vast range of topics in his writings on practical ethics. (shrink)

In 1956, a series of BBC radio talks was published in London under the title The Revolution in Philosophy . This short book included papers by prominent British philosophers of the day, such as Sir Alfred Ayer and Sir Peter Strawson, with an introduction by Gilbert Ryle. Although there is precious little in it concerning the precise nature of the ‘revolution’ alluded to in the title, it is quite clear that these lectures were meant to celebrate in an insular manner (...) the birth of ‘analytic philosophy’ at the hands of Moore, Russell, and Wittgenstein. The use of the word ‘revolution’ to describe the birth of ‘analytical philosophy’ and its rise to near complete dominance in the British universities thus carries with it connotations of a forcible substitution of one philosophical order by a new one that itself owed nothing to the past. To me, however, this talk of ‘revolution’ carries with it a false view of the history of British philosophy: it isn’t ‘historical’ at all, just ideological; it was introduced for a strategic purpose, namely that of encouraging new generations of students to avoid reading the work of earlier philosophers or becoming interested in the problems that concerned them. I shall sketch the broad outlines of a landscape that involves, when limited to the specific topic of the theory of knowledge, no radical break, where no entirely new order replaces an older one: the options, so to speak, and even some of the arguments are the same before and after the soi-disant ‘revolution’.

In this essay, I want to take another look at the phenomenon of transparency and its relevance to qualia realism and representationalism. I don’t suppose that what I have to say will cause those who disagree with me to change their minds, but I hope not only to clarify my position and that of others who are on my side of the debate but also to respond to various criticisms and objections that have arisen over the last 10–15 years or (...) so.The transparency thesisI begin with four quotations, two from G. E. Moore, one from Gilbert Harman, and one from an earlier paper of mine:…that which makes the sensation of blue a mental fact seems to escape us; it seems, if I may use a metaphor, to be transparent — we look through it and see nothing but the blue… (Moore 1903, p. 446).When we try to introspect the sensation of blue, all we can see is the blue: the other element is as if it were diaphanous (Moore 1903, p. 450).When Eloise sees a tree before her, the colors she experiences are all experien.

1. Introduction In ‘The Refutation of Idealism’, G.E.Moore observed that, "when we try to introspect the sensation of blue, all we can see is the blue: the other element is as if it were diaphanous" (1922; p.25). Many philosophers, but Gilbert Harman (1990, 1996) in particular, have suggested that this observation forms the basis of an argument against qualia, usually called the argument from diaphanousness or transparency.1 But even its friends concede that it is none too clear what the argument (...) from diaphanousness—as I will call it—is (Tye 2000; p.45).2 The purpose of this paper is to formulate the argument, and to assess its merits. My conclusion will be that qualia realists have little to fear from the argument—provided both qualia and diaphanousness are properly understood. (shrink)

Analytic philosophy is difficult to define since it is not so much a specific doctrine as a loose concatenation of approaches to problems. As well as having strong ties to scientism -the notion that only the methods of the natural sciences give rise to knowledge -it also has humanistic ties to the great thinkers and philosophical problems of the past. Moreover, no single feature characterizes the activities of analytic philosophers. Undaunted by these difficulties, Avrum Stroll investigates the "family resemblances" between (...) that impressive breed of thinkers known as analytic philosophers. In so doing, he grapples with the point and purpose of doing philosophy: What is philosophy? What are its tasks? What kind of information, illumination, and understanding is it supposed to provide if it is not one of the natural sciences? Imbued with clarity, liveliness, and philosophical sophistication, Stroll´s book presents a synoptic picture of the main developments in logic, philosophy of language, epistemology, and metaphysics in the past century. It does this by concentrating on the individual thinkers whose ideas have been most influential. Major themes in Twentieth-Century Analytic Philosophy include: · the innovation of mathematical logic by Gottlob Frege at the close of the nineteenth century and its independent development by Bertrand Russell; · the impact of advancements in science on the world of philosophy and its importance for understanding such doctrines as logical positivism, philosophy of language, philosophy of mind, and eliminative materialism; · the refusal by such thinkers as Wittgenstein, Moore, and Austin to treat logic as an ideal language superior to natural languages; and · a conjecture about which, if any, of the philosophers discussed in the book will enter the pantheon of philosophical gods. Along the way, Stroll also covers the theories of Rudolf Carnap, W. V. O. Quine, Gilbert Ryle, J. L. Austin, Hilary Putnam, Saul Kripke, John Searle, Ruth Marcus, and Patricia and Paul Churchland. Stroll´s approach to his subject treats the critical movements in analytic philosophy in terms of the philosophers who defined them. The notoriously complex realm of analytic philosophy emerges less as an abstract enterprise than as a domain of personalities and their competing methods and arguments. The book´s inventive presentations of complex logical doctrines relate them to the traditional problems of philosophy, seeking the continuity between them rather than polemical distinctions so as to bring the true differences of their respective achievements into sharper focus.

This is an attempt at reviving Kneale's version of the description theory of names, which says that a proper name is synonymous with a definite description of the form ‘the individual named so-and-so’. To begin with, I adduce a wide range of observations to show that names and overt definites are alike in all relevant respects. I then turn to Kripke's main objection against Kneale's proposal, and endeavour to refute it. In the remainder of the paper I elaborate on Kneale's (...) analysis, adopting a theory of presupposition proposed by van der Sandt. (shrink)

According to the error theory, normative judgements are beliefs that ascribe normative properties, even though such properties do not exist. In this paper, I argue that we cannot believe the error theory, and that this means that there is no reason for us to believe this theory. It may be thought that this is a problem for the error theory, but I argue that it is not. Instead, I argue, our inability to believe the error theory undermines many objections that (...) have been made to this theory. (shrink)

Many philosophers argue that the error theory should be rejected because it is incompatible with standard deontic logic and semantics. We argue that such formal objections to the theory fail. Our discussion has two upshots. First, it increases the dialectical weight that must be borne by objections to the error theory that target its content rather than its form. Second, it shows that standard deontic logic and semantics should be revised.

Walter Sinnott-Armstrong argues that 'ought' does not entail 'can', but instead conversationally implicates it. I argue that Sinnott-Armstrong is actually committed to a hybrid view about the relation between 'ought' and 'can'. I then give a tensed formulation of the view that 'ought' entails 'can' that deals with Sinnott-Armstrong's argument and that is more unified than Sinnott-Armstrong's view.

There is a well‐known argument against irreducibly normative properties that appeals to the following claim about supervenience: for all possible worlds W and W*, if the instantiation of descriptive properties in W and W* is exactly the same, then the instantiation of normative properties in W and W* is also exactly the same. This claim used to be uncontroversial, but recently several philosophers have challenged it. Do these challenges undermine this argument? I argue that they do not, since the negation (...) of this claim about supervenience has consequences that are much more implausible than the negations of key premises in these challenges. (shrink)

We argued that formal objections to the error theory overgeneralize and therefore fail. Christine Tiefensee and Gregory Wheeler deny this. We argue that they are wrong, for two reasons. The first concerns how we should adjudicate conflicts between formal and substantive commitments. The second concerns an overlooked tension between formal objections and non-error-theoretic views. Our discussion shows that the commitments behind formal objections to the error theory, such as the dual schema, should be regarded as much more contentious than is (...) often assumed. (shrink)

Jonathan Dancy thinks that there are irreducibly normative properties. Frank Jackson has given a well-known argument against this view, and I have elsewhere defended this argument against many objections, including one made by Dancy. But Dancy remains unconvinced. In this chapter, I hope to convince him.

Some philosophers think that normative properties are identical to descriptive properties. In this paper, I argue that this entails that it is possible to say which descriptive properties normative properties are identical to. I argue that Frank Jackson's argument to show that this is possible fails, and that the objections to this argument show that it is impossible to say which descriptive properties normative properties are identical to. I conclude that normative properties are not identical to descriptive properties. I then (...) show that if we combine this conclusion with the conclusion of a different argument that Jackson has given to show that there are no irreducibly normative properties, it follows that there are no normative properties at all.

Some philosophers have argued recently that introspective evidence provides direct support for an intentionalist theory of visual experience. An intentionalist theory of visual experience treats experience as an intentional state, a state with an intentional content. (I shall use the word ’state’ in a general way, for any kind of mental phenomenon, and here I shall not distinguish states proper from events, though the distinction is important.) Intentionalist theories characteristically say that the phenomenal character of an experience, what it is (...) like to have the experience, is exhausted by its intentional content. Visual experience, and on some views sense-experience generally, does not involve the awareness of ’qualia’, intrinsic, non-intentional features of the experience. According to Gilbert Harman and Michael Tye, support for this view comes from introspecting on experience. Tye describes his ’argument from introspection’ as follows: Standing on the beach in Santa Barbara a couple of summers ago on a bright sunny day, I found myself transfixed by the intense blue of the Pacific Ocean. Was I not here delighting in the phenomenal aspects of my visual experience? And if I was, doesn’t this show that there are visual qualia? I am not convinced. It seems to me that what I found so pleasing in the above instance, what I was focusing on, as it were, were a certain shade and intensity of the colour blue. I experienced blue as a property of the ocean not as a property of my experience. My experience itself certainly wasn’t blue. Rather, it was an experience which represented the ocean as blue. What I was really delighting in, then, were specific aspects of the content of the experience. Tye goes on to suggest that this might have been the sort of thing Moore meant when he said that the sensation of blue is ’diaphanous’, and glosses this as follows: When one tries to focus on it in introspection one cannot help but see right through it so that what one actually ends up attending to is the real colour blue. 1An early version of this paper was presented at the conference, Mental Phenomena III in Dubrovnik, Croatia..

Reductive realists about normative properties are often charged with being relativists: it is often argued that their view implies that when two people make conflicting normative judgements, these judgements can both be true. I argue that reductive realists can answer this charge by copying the quasi-realist moves that many expressivists make. I then argue that the remaining difference between reductive realism and expressivism is unimportant.

To be able to say what practical reasoning is, we first need to say what reasoning is and what the conclusion of a process of reasoning is. I shall do this in sections 1 and 2. We can then make a distinction between practical and theoretical reasoning. There are three main ways to do this, which I shall survey in sections 3 to 5. I shall end by suggesting that there are different kinds of practical reasoning.

In the law, it is generally acknowledged that there are intuitive differences between reasoning with rules and reasoning with principles. For instance, a rule seems to lead directly to its conclusion if its condition is satisfied, while a principle seems to lead merely to a reason for its conclusion. However, the implications of these intuitive differences for the logical status of rules and principles remain controversial.A radical opinion has been put forward by Dworkin (1978). The intuitive differences led him to (...) argue for a strict logical distinction between rules and principles. Ever since, there has been a controversy whether the intuitive differences between rules and principles require a strict logical distinction between the two. For instance, Soeteman (1991) disagrees with Dworkin's opinion, and argues that rules and principles cannot be strictly distinguished, and do not have a different logical structure. (shrink)

Reprise d’un article de G. Durand initialement paru en 1963 dans les Cahiers internationaux de symbolisme. L’auteur examine trois périodes de la culture occidentale où l’image et l’imagination ont été dévalorisées au profit de la pensée rationnelle : le conceptualisme aristotélicien déformé par l’averroïsme médiéval, le dogmatisme de l’Église chrétienne d’Occident opposé à l’iconodulie byzantine, le scientisme issu de la pensée de Descartes. L’analyse conduit à une nouvelle théorie du symbole conçu comme pouvoir heuristique des images. Reprint of an article (...) by G.

This analysis leads to a new theory about the symbols, conceived as a creative thinking and an heuristic power of images. (shrink)

It is sometimes suggested that there are two kinds of reasoning: inferential reasoning and non-inferential reasoning. However, it is not entirely clear what the difference between these two kinds of reasoning is. In this paper, I try to answer the question what this difference is. I first discuss three answers to this question that I argue are unsatisfactory. I then give a different answer to this question, and I argue that this answer is satisfactory. I end by showing that this (...) answer can help to resolve some disagreements in which the difference between inferential and noninferential reasoning plays a role. (shrink)
