That freedom involves a power (or right) to choose is a natural idea. But it requires a model of man which English philosophers have usually rejected. It requires an agent equipped with a will, who is faced with genuine alternatives and is, in some sense, autonomous. So it is rejected both by those, like Hobbes, who hold a strong version of determinism and by those, like Hume, who deny the existence of an autonomous self. The will, says Hobbes, is simply ‘the last appetite in deliberating’. A mind, says Hume, is ‘nothing but a heap or collection of different perceptions, united together by certain relations’. The way is then apparently open for a denial that men ever act freely at all and so for a thoroughly deterministic basis for the social sciences. But this is not the usual conclusion. Hobbes and Hume both agree that there is no conflict between freedom and determinism, once ‘freeedom’ is properly understood. A man is free when he can get what he wants. As Hobbes puts it, ‘liberty is the absence of all impediments to action which are not contained in the nature and intrinsical quality of the agent’. In other words freedom does not involve choice but consists instead in the power to satisfy desire.
