Abstract

This chapter identifies three main sources of the Stoic elements in Hobbes's philosophy: the early Christian‐Stoic Tertullian, the modern “Neo‐Stoic” school of Justus Lipsius, and the natural philosophers of the Cavendish Circle he frequented. Perhaps the most direct Stoical impact on Hobbes was the second/third century Church Father Tertullian. Hobbes and Cavendish are at bottom kindred Stoic spirits, though their systems diverge on the precise nature of material activity. The chapter explores the Stoic character of Hobbesian space, time, causality, and God, especially as these notions are employed in his natural philosophy. Hobbes's quasi‐realism about imaginary space is highly reminiscent of the Stoics' conception of pure space as one of the problematic “incorporeals.” The chapter shows that Hobbes's metaphysical views, though quite unorthodox in his day, served to buttress his overall materialist, empiricist, and mechanist program in natural philosophy.
