"This is an important book, and no one interested in issues which touch on the free will will want to ignore it."--Ethics. In this stimulating and thought-provoking book, the author defends the thesis that free will is incompatible with determinism. He disputes the view that determinism is necessary for moral responsbility. Finding no good reason for accepting determinism, but believing moral responsiblity to be indubitable, he concludes that determinism should be rejected.

This article begins with some brief reflexions on the definition of determinism (II), on the notion of the subject of experience (III), and on the relation between conscious experience and brain events (IV). The main discussion (V?XIII) focuses on the traditional view, endorsed by Honderich in his book A Theory of Determinism, that the truth of determinism poses some special threat to our ordinary conception of ourselves as morally responsible free agents (and also to our ?life?hopes'). It is argued that this is half right: the truth of determinism does indeed threaten certain vital parts of our ordinary conception of ourselves as morally responsible free agents. The trouble is that the falsity of determinism does not diminish the threat in any useful way. The old, natural, and recurrent mistake is to think that we would really be better off, so far as free will and moral responsibility (and our ?life?hopes') were concerned, if determinism were false. It is argued that there is no important sense in which this is true, and that the question of whether determinism is true or false is therefore of no real importance, so far as the free will debate is concerned.

The perennial fear associated with the free will problem is the prospect of hard determinism being true. Unlike prevalent attempts to reject hard determinism by defending compatibilist analyses of freedom and responsibility, this article outlines a pragmatic argument to the effect that we are justified in betting that determinism is false even though we may retain the idea that free will and determinism are incompatible. The basic argument is that as long as we accept that libertarian free will is worth wanting, there is a defensible rationale, given the uncertainty which remains as to whether determinism is true or false, to refrain from acting on hard determinism, and thus to bet that libertarian free will exists. The article closes by discussing two potentially decisive objections to this pragmatic argument.

The Theory of Important Criteria is used to argue that the age?old problem of the compatibility of free will and determinism turns on the question of the importance of causal indeterminacy of choice as a criterion of being able to do otherwise. One's answer to this question depends in turn on one's evaluation of certain moral issues and of the force and significance of certain similes, analogies and diagrams in terms of which one can ?depict? a deterministic universe. It is further argued that the problem of free will and determinism is not a pseudo?problem, but a genuine problem that is hard to solve because of the depth and complexity of the evaluative issues on which it hangs.

What values, if any, would be undermined by determinism?[i] Traditionally this question has been tackled by asking whether determinism is compatible with free will or whether it is compatible with moral responsibility. Compatibilists say that determinism would not threaten free will or moral responsibility, and hence that people’s values should not be influenced by whether or not they believe in determinism. Incompatibilists say that determinism would undermine free will or moral responsibility, and hence that a belief in determinism should have a considerable impact on one’s values, precluding many popular evaluative beliefs.

In this fully revised and up-to-date edition of Ted Honderich's modern classic, he offers a concise and lively introduction to free will and the problem of determinism, advancing the debate on this key area of moral philosophy. Honderich sets out a determinist philosophy of mind, in response to the question, "Is there a really clear, consistent and complete version of determinism?" and asks instead if there is such a clear version of free will. He goes on to address the question of whether determinism is true and finally asks, "What can we conclude about our lives if determinism is true?".

Thoughts about freedom and determinism have engaged philosophers since the days of ancient Greece.¹ On the one hand, we generally regard ourselves as free and autonomous beings who are responsible for the ac- tions that we perform. But this idea of ourselves appears to conflict with a variety of attitudes that we also have about the inevitable workings of the world around us. For instance, some people believe that strict, universal laws of nature govern the world. Others think that there is an omnipotent God who is the ultimate cause of all things. These more global views sug- gest that each particular event—including each human action—is causally necessitated, and so they suggest a conflict with the claim that we are free. Hence, the problem of freedom and determinism is, at base, a problem about reconciling attitudes we have toward ourselves with our more gen- eral thoughts about the world around us. It is a problem about locating our actions within those streams of events that make up the broader universe.

Determinism is a claim about the laws of nature: very roughly, it is the claim that everything that happens is determined by antecedent conditions together with the natural laws. Incompatibilism is a philosophical thesis about the relevance of determinism to free will: that the truth of determinism rules out the existence of free will. The incompatibilist believes that if determinism turned out to be true, it would also be true that we don't have, and have never had, free will. The compatibilist denies that determinism has the consequences the incompatibilist thinks it has. According to the compatibilist, the truth of determinism does not preclude the existence of free will. (Even if we learned tomorrow that determinism is true, it might still be true that we have free will.) The philosophical problem of free will and determinism is the problem of understanding, how, if at all, the truth of determinism might be compatible with the truth of our belief that we have free will. That is, it's the problem of deciding who is right: the compatibilist or the incompatibilist.

Popular and scientific accounts of the U.S. Human Genome Project often express concern about the implications of the project for the philosophic question of free will and responsibility. However, on its standard construal within philosophy, the question of free will versus determinism poses no special problems in relation to genetic research. The paper identifies a variant version of the free will question, free will versus internal constraint, that might well pose a threat to notions of individual autonomy and virtue in connection with genetic research. Whether it does depends on the extent to which the genetic basis for behavior turns on behavioral incapacities.
