The above citations may be used as the basis for further reading on this subject in the following way. Influential statements of the classical interpretation of Hume’s intentions can be found in Flew (1962), Penelhum (1975) and Stroud (1977). Prominent statements of 20th century classical compatibilism that are generally taken to follow in Hume’s tracks include Schlick (1939), Ayer (1954) and Smart (1961). Davidson (1963) provides an important statement of the causal theory of action based on broadly Humean principles. A complete statement of the naturalistic interpretation is provided in Russell (1995), esp. Part I. For a critical response to this study see Penelhum (1998; 2000a), and also the earlier exchange between Russell (1983, 1985) and Flew (1984). The contributions by Botterill (2002) and Pitson (2016) follow up on some of the issues that are at stake here. For an account of Hume’s views on punishment – a topic that is closely connected with the problem of free will – see Russell (1990) and Russell (1995 – Chp. 10). For a general account of the 18th century debate that Hume was involved in see Harris (2005) and Russell (2008), Chap. 16. See also O’Higgins introduction [in Collins (1717)] for further background. The works by Hobbes, Locke, Clarke and Collins, as cited above, are essential reading for an understanding of the general free will debate that Hume was involved in. Smith (1759) is a valuable point of contrast in relation to Hume’s views, insofar as Smith develops a naturalistic theory of responsibility based on moral sentiment (which Strawson follows up on). However, Smith does not discuss the free will issue directly (which is itself a point of some significance). In contrast with this, Reid (1788) is perhaps Hume’s most effective and distinguished contemporary critic on this subject and his contribution remains of considerable interest and value. With respect to Hume’s views on free will as they relate to his more general irreligious intentions see Russell (2008 – esp. Chp. 16). Similar material is covered in Russell (2016). Garrett (1997) provides a lucid overview and careful analysis of Hume’s views on liberty and necessity, which includes discussion of the theological side of Hume’s arguments and concerns. Helpful introductions discussing recent developments in compatibilist thinking, which are of obvious relevance for an assessment of the contemporary value of Hume’s views on this subject, can be found in McKenna (2004) and Kane (2005). Among the various points of contrast not discussed in this article, Frankfurt (1971) is an influential and important paper that aims to advance the classical compatibilist strategy beyond the bounds of accounts of freedom of action. However, as noted in the main text of this article, the work of P.F. Strawson (1962, 1985) is of particular importance in respect of the contemporary significance and relevance of Hume’s naturalistic strategy. Finally, for discussions of Hume’s compatibilism as it relates to his theory of causation see, for example, Russell (1988), Russell (1995), esp. Chaps.1–3, Beebee &amp; Mele (2002), Harris (2005), Chap. 3, Millican (2010), and Berofsky (2012).
