"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.

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?".

In this paper I shall define a thesis I shall call 'determinism', and argue that it is incompatible with the thesis that we are able to act otherwise than we do (i.e., is incompatible with 'free will'). Other theses, some of them very different from what I shall call 'determinism', have at least an equal right to this name, and, therefore, I do not claim to show that every thesis that could be called 'determinism' without historical impropriety is incompatible with free will. I shall, however, assume without argument that what I call 'determinism' is legitimately so called. In Part I, I shall explain what I mean by 'determinism'. In Part II, I shall make some remarks about 'can'. In Part III, I shall argue that free will and determinism are incompatible. In Part IV, I shall examine some possible objections to the argument of Part III. I shall not attempt to establish the truth or falsity of determinism, or the existence or nonexistence of free will.

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.

The spectre of determinism stalks many of the concerns surrounding the impact of genetic research into both disease and normal behaviour. The ability accurately to predict a person's actions would certainly have profound implications for notions of individuality and free will. But to what extent will the current explosion in genetic research provide more accurate predictors than have been available for millennia in the form of wealth, social status and perceived family resemblance? The genetic research program is at too early a stage to answer this question with confidence, but various indicators tend to point in the same direction: the predictive ability of genetic analysis will generally be low. This conclusion runs counter to widely perceived popular notions. The deconstruction of genetic determinism is an essential safeguard against the real concern that genetic information may be used for discrimination by unscrupulous powers.

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.

I was led to this clarificatory job initially by some puzzlement from a philosopher's standpoint about just why free will questions should come up particularly in connection with the genome project, as opposed to the many other scientific research programs that presuppose determinism. The philosophic concept of determinism involves explanation of all events, including human action, by prior causal factors--so that whether or not human behavior has a genetic basis, it ultimately gets traced back to _something_ true of the world before our birth. The philosophic problem of free will and determinism arises because this seems to undercut moral responsibility: How can we reasonably be held responsible for something whose causes we couldn't control?

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.

This paper has two parts. In the first part, I concede an error in an argument I have given for the incompatibility of free will and determinism. I go on to show how to modify my argument so as to avoid this error, and conclude that the thesis that free will and determinism are compatible continues to be—to say the least—implausible. But if free will is incompatible with determinism, we are faced with a mystery, for free will undeniably exists, and it also seems to be incompatible with indeterminism. In the second part of this paper, I will defend the conclusion that the concept of agent causation is of no use to the philosopher who wants to maintain that free will and indeterminism are compatible. I conclude that free will remains a mystery---that is, that free will undeniably exists and that there is a strong and unanswered prima facie case for its impossibility.
