How did Euclid’s Elements influence Thomas Hobbes?

Thomas Hobbes’s encounter with Euclid’s Elements in the late 1620s or early 1630s was a transformative moment that sparked his deep interest in geometry and scientific methodology.1

According to contemporary accounts, Hobbes was captivated by Euclid’s systematic method of demonstrating theorems. This experience profoundly influenced his approach to philosophy, leading him to believe that the construction and maintenance of a commonwealth should rely on clear, logical rules similar to those found in arithmetic and geometry, rather than on mere practice or experience.12

By adopting this rigorous, deductive framework, Hobbes sought to create a science of politics that traced observed phenomena to fundamental principles. He viewed his own philosophical system as a hierarchy, moving from general laws of matter and motion to specific applications in psychology and politics. Ultimately, Euclid’s influence provided the structural model for Hobbes’s attempt to provide a pragmatic, logical justification for the sovereign state.132
