 Godwin’s major philosophical treatise is his Enquiry Concerning Political Justice. The work went through three editions within 5 years, each with substantial changes. No further edition was published in Godwin’s lifetime, although a fourth edition was certainly mooted and Godwin may have undertaken work towards it. Although Godwin’s other works shed light on changes in Godwin’s position after 1798, Political Justice is the most coherent expression of his political philosophy.
