‘Why may not man one day be immortal?’: Population, perfectibility, and the immortality question in Godwin's Political Justice

Godwin's controversial claim for earthly immortality in the first edition of Political Justice has been largely dismissed by scholars as a flaw in his philosophy or as absurd speculation which Godwin cannily omitted from the later editions of the text. In this paper, I will demonstrate, not only that such claims were not nearly as idiosyncratic or eccentric as they have been presented, but that they constitute an intrinsic part of his overall philosophy regarding perfectibility and human progress. Moreover, by examining the revisions made to Political Justice in the second and third editions, it will be possible to prove that the essence of his argument regarding material immortality was not as radically altered as is widely accepted. I will further show how the population controversy of the 18th century forced Godwin to apply his perfectibilist theory to contemporary demographic challenges and how he defended his concept of immortality from both the principle of population and, more particularly, Malthusian philosophy.
