Lucretius' account of the origin of life, the origin of species, and human prehistory is the longest and most detailed account extant from the ancient world. It gives an anti-teleological mechanistic theory of zoogony and the origin of species that does away with the need for any divine aidor design in the process, and accordingly it has been seen as a forerunner of Darwin's theory of evolution. This commentary locates Lucretius in both the ancient and modern contexts, and treats Lucretius' ideas as very much alive rather than as historical concepts. The recent revival of creationismmakes this study particularly relevant to contemporary debate, and indeed, many of the central questions posed by creationists are those Lucretius attempts to answer.

The Roman philosopher's didactic poem in 6 parts, De Rerum Natura — On the Nature of Things — theorizes that natural causes are the forces behind earthly phenomena and dismisses divine intervention. Derived from the philosophical materialism of the Greeks, Lucretius' work remains the primary source for contemporary knowledge of Epicurean thought.

This book demonstrates the way in which William Blake aligned his idiosyncratic concept of the Selfhood – the lens through which the despiritualised subject beholds the material world – with the atomistic materialism of the Epicurean school as it was transmitted through the first-century BC Roman poet and philosopher Lucretius’ De Rerum Natura. By addressing this philosophical debt, this study sets out a threefold re-evaluation of Blake’s work: to clarify the classical stream of Blake’s philosophical heritage through Lucretius; to return Blake to his historical moment, a thirty-year period from 1790 to 1820 which has been described as the second Lucretian moment in England; and to employ a new exegetical model for understanding the phenomenological parameters and epistemological frameworks of Blake’s mythopoeia. Accordingly, it is revealed that Blake was not only aware of classical atomistic cosmogony and sense-based epistemology but that he systematically mapped postlapsarian existence onto an Epicurean framework.
