Abstract

Hobbes argues that among the reasons for the Catholic Church’s power is the difficulty for ignorant people to understand the causes of natural phenomena. They take the motion of invisible bodies for the intervention of incorporeal agents. For Hobbes, the Church tries to perpetuate this profitable misunderstanding by spreading Scholastic doctrines supporting this idea in the sermons of all the parishes of the Christian world. Existing literature, thus far, focused almost exclusively on Hobbes’ negative claim concerning incorporeal substances, i.e., that they are absurd and are only used to justify the Church’s claim to power. On the other hand, his positive proposition to replace immaterial substances with invisible bodies was not fully explored. By highlighting Hobbes’ examination of invisibility in Leviathan, it is possible to demonstrate how he uses ideas from natural philosophy to challenge some of the dominant Scholastic doctrines and, consequently, the usurpation of the sovereign’s ecclesiastical power.
