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.

In his A Treatise of Freewill, Ralph Cudworth argues against Stoic determinism by drawing on what he takes to be other concepts found in Stoicism, notably the claim that some things are ‘up to us’ (ἐφ᾽ ἡμῖν) and that these things are the product of our choice (προαίρεσις). These concepts are central to the late Stoic Epictetus and it appears at first glance as if Cudworth is opposing late Stoic voluntarism against early Stoic determinism. This paper argues that in fact, despite his claim to be drawing on Stoic doctrine, Cudworth uses these terms with a meaning first articulated only later, by the Peripatetic commentator Alexander of Aphrodisias.

This paper suggests that the arguments for compatibilism are invalid because they use incompatible definitions of causal determinism and free will, an illegitimate definition of free will, and a logical fallacy concerning free will and morality.

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.

"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.

Most philosophers now concede that libertarianism has failed as an account of free will. Assuming the correctness of this concession, that leaves compatibilism and hard determinism as the only remaining choices in the free will debate. In this paper, I will argue that hard determinism turns out to be a form of compatibilism, and therefore, compatibilism is the only remaining position in the free will debate. I will attempt to establish this conclusion by arguing that hard determinists will end up punishing or rewarding the same acts (and omissions) that the compatibilists punish and reward. Next, I will respond to several objections that attempt to pry apart hard determinism and compatibilism. It will emerge not only that hard determinism and compatibilism are identical at the practical level, but also that the key terms employed by the hard determinist have the same meaning as equivalent terms ("free," "morally responsible," and "retributive punishment") employed by the compatibilist. I conclude that hard determinism genuinely is a form of compatibilism.

It is agreed by most scholars that the Stoics were compatibilists regarding the relation between responsibility and determinism. On this view, the Stoics depart from two other positions. Unlike some eliminative determinists — labelled in modern discussions “hard-determinists”, but already active in Antiquity — they assert that, despite determinism, there are things that “depend on us”, or are : things for which we are genuinely responsible and for which, therefore, we may justifiably be praised or blamed. But the Stoics also depart from the libertarian or “anti-determinist” 2 a position championed by the Epicureans in the early Hellenistic period and by Alexander of Aphrodisias on behalf of the Peripatetics, towards the end of the second century AD. Unlike the libertarian, who agrees on the incompatibility alleged by the hard-determinist, but preserves responsibility by rejectin necessitation, the Stoics preserve both responsibility and necessitation.

Bobzien presents the definitive study of one of the most interesting intellectual legacies of the ancient Greeks: the Stoic theory of causal determinism. She explains what it was, how the Stoics justified it, and how it relates to their views on possibility, action, freedom, moral responsibility, and many other topics. She demonstrates the considerable philosophical richness and power that these ideas retain today.
