Abstract

This chapter examines the changes in the concept of substance and essence in British philosophy during the seventeenth century. It analyzes the roles played by substance and essence in different versions of scholastic and Aristotelian philosophy studied and taught during this period, and considers the criticism of Thomas Hobbes, Robert Boyle, and John Locke on these issues. The chapter suggests that Hobbes, Boyle, and Locke engaged with the context of scholastic logic and metaphysics in their discussions of substance and their attempts to reject and replace theories of substantial form.
