Although it is widely recognized that David Hume's (1729-40) belongs among the greatest works of philosophy, there is little aggreement about the correct way to interpret his fundamental intentions. The solution to this riddle depends on challenging another, closely related, point of orthodoxy: namely, that before Hume published the he removed almost all material concerned with problems of religion. Russell argues, contrary to this view, that irreligious aims and objectives are fundamental to the and account for its underlying unity and coherence. It is Hume's basic anti-Christian aims and objectives that serve to shape and direct both his skeptical and naturalistic commitments. When Hume's arguments are viewed from this perspective we can solve, not only puzzles arising from his discussion of various specific issues, we can also explain the intimate and intricate connections that hold his entire project together. This "irreligious" interpretation provides a comprehensive fresh account of the nature of Hume's fundamental aims and ambitions in the . It also presents a radically different picture of the way in which Hume's project was rooted in the debates and controversies of his own time, placing the in an irreligious or anti-Christian philosophical tradition that includes Hobbes, Spinoza and freethinking followers. Considered in these terms, Hume's constitutes the crowning achievement of the Radical Enlightenment.
