In his discussion note ‘J. J. C. Smart, Materialism and Occam's Razor’ Peter Glassen argues that it was inconsistent of me both to assert that realism is true and that Occam's razor is a reason for the materialist thesis. Glassen says that Occam's razor ‘ is not a physical thing, state or process at all ’. A little further down on the same page he uses the phrase ‘material or physical thing, state, or process’. It is possible, therefore, that (...) Glassen regards the distinction between ‘material’ and ‘physical’ as unimportant in the present context. I think however that one way of replying to Glassen turns on this distinction. (shrink)

The main purpose of this paper is to seek a reconciliation between two apparently conflicting views of mine. I have argued (for example, Smart, 1963) for realism about theoretical entities, for example electrons, protons, photons, possibly space-time points, perhaps the ‘Y’-wave of Schrödinger’s equation and so on. Quine has also plausibly argued that we should believe in mathematical entities, since in physics we quantify over them no less than over electrons and protons. I except cases in which in physics (...) the existential quantifications are part of merely pretence discourse. Perhaps in spherical astronomy talk of the celestial sphere should be treated in this way. Alternatively the celestial sphere could be thought of realistically as a sphere whose centre is that of the earth while the stars and planets are thought of (or correlated with) points or small areas on the sphere’s surface in their lines of sight. I am not concerned in this paper to delimit fact from fiction in scientific discourse. The settlement of borderline disputes can wait for another occasion. My main argument for scientific realism is the cosmic coincidence argument. Would it not be a cosmic coincidence if the world were merely as if there were electrons, protons, etc?1. (shrink)

Two essays on utilitarianism, written from opposite points of view, by J. J. C. Smart and Bernard Williams. In the first part of the book Professor Smart advocates a modern and sophisticated version of classical utilitarianism; he tries to formulate a consistent and persuasive elaboration of the doctrine that the rightness and wrongness of actions is determined solely by their consequences, and in particular their consequences for the sum total of human happiness. In Part II Bernard Williams offers (...) a sustained and vigorous critique of utilitarian assumptions, arguments and ideals. He finds inadequate the theory of action implied by utilitarianism, and he argues that utilitarianism fails to engage at a serious level with the real problems of moral and political philosophy, and fails to make sense of notions such as integrity, or even human happiness itself. This book should be of interest to welfare economists, political scientists and decision-theorists. (shrink)

In this article I try to refute the so-called "libertarian" theory of free will, and to examine how our conclusion ought to modify our common attitudes of praise and blame. In attacking the libertarian view, I shall try to show that it cannot be consistently stated. That is, my dscussion will be an "analytic-philosophic" one. I shall neglect what I think is in practice an equally powerful method of attack on the libertarian: a challenge to state his theory in such (...) a way that it will fit in the modern biology and psychology, which are becoming increasingly physicalistic.

It has frequently been lamented that while the human species has made immense progress in science it is nevertheless ethically backward. This ethical backwardness is all the more dangerous because the advanced state of scientific knowledge has made available a technology with which we are able to destroy ourselves—indeed a technology which may have got so much out of hand that we may not even have the capacity to prevent it from destroying us.

The title of this paper is in many ways a bad one, but it does have the advantage of familiarity, and so indicates a well-known group of questions. The questions which philosophers who have talked about “Reason and Conduct” have really been discussing and which they help us to answer have been these: “What are the various ways in which the words “reasonable,” ‘wise,’ ‘foolish,’ etc., are used?” “In what senses may actions and choices be called ‘reasonable,’ and are these (...) senses of ‘reasonable’ connected in any way, and if so in what way, with the senses in which beliefs and inferences may be called ‘reasonable’?” In other words our questions are, in a broad sense of the word, logical questions, not empirical ones. It is misleading to say, therefore, as philosophers commonly do, that we are discussing the relationship between Reason and Conduct, or that we are going into the question of whether Reason can or cannot be practical. Reason is the faculty of acting reasonably. If under “acting reasonably” we include only “inferring properly,” then Reason can only be logical. If under “acting reasonably” we also include making correct inductions and concocting good theories then Reason can also be scientific. If under “acting reasonably” we include “acting morally” or “doing one's duty,” then Reason can be practical. The dispute about whether Reason can be practical is not merely verbal but trivial, and only appears not to be trivial when we hypostatize this faculty Reason and suppose it to be a thing. It then looks as though our dispute is an empirical one about what this thing Reason can do. (shrink)

This article indicates some ways in which the fantasy of the brain in the vat has been used in thought experiments to discuss important philosophical problems. The first has to do with scepticism about the external world. The second has to do with Hilary Putnam’s arguments for the indeterminacy of reference and his rejection of metaphysical realism. The third issue to which the brain in the vat is relevant has to do with the difference between broad and narrow content of (...) beliefs and Putnam’s challenging assertion that reference is not ‘in the head’. Though there are brief suggestions for dealing with these problems and saving metaphysical realism, the main purpose is to indicate the relevance of the fantasy of the brain in the vat to discussion of these issues.
