In the Treatise Hume tends to identify liberty with indifference rather than spontaneity and even suggests “that liberty and chance are synonimous” (T 2.3.2.8/412; cf. T 2.3.1.18/407; but see also EU 8.25/96). For this reason he presents his arguments as aiming to show that liberty, so understood (qua indifference), is, if not contradictory, “directly contrary to experience” (T 2.3.1.18/407). In placing emphasis on this negative task of refuting “the doctrine of liberty or chance” (T 2.3.2.7/412), Hume is happy to present himself as coming down firmly on the side of “the doctrine of necessity” (T 2.3.2.3/409), which he is careful to define in a way that avoids any confusion between causation and compulsion or force (as is explained in more detail below). The account that Hume offers in the Enquiry strikes a more balanced note. In this work Hume presents his position as not so much a refutation of “the doctrine of liberty” or “free-will” (T 2.3.1.18/407; cf. T 2.1.10.5/312), but rather as a “reconciling project with regard to the question of liberty and necessity” (EU 8.23/95; although even in the Enquiry his references to liberty are not uniformly to spontaneity). Although these differences should be noted, it is important not to exaggerate them. In the Treatise Hume makes clear that liberty of spontaneity is “the most common sense of the word” and the “only… species of liberty, which it concerns us to preserve” (T 2.3.2.1/407–8). It is evident, therefore, that there is also a “reconciling project” implicit in the Treatise and that his arguments against “the doctrine of liberty” remain tightly focused on liberty of indifference.
