The chapter presents respective views of Hobbes and Leibniz on the issue of universals and human cognition. This chapter represents a bridge between the chapter on space and the chapter on law. Hobbesian nominalism rejecting any universals but names can only be fully appreciated against his views on space, materiality of which emerges form the materiality of bodies. This focus on materiality determining his nominalism also defines his view of human cognition where truth is simply an able use of language. Leibniz’s space as a logical grounding, as an order of relationships determines his belief in the existence of universals as well as his insistence on the capacity of human mind to access eternal truths. Thus, if for Hobbes the main question becomes how to control discourse, for Leibniz the central issue is articulation of ways to discover and thus know eternal truths.
