 In Leviathan and De Corpore something more complex goes on (Duncan 2011). The equivalent chapters in Leviathan and De Corpore start in the same way, with discussions of the role of names as marks to aid the memory (Hobbes 1651, 4.3; Hobbes 1655, 2.1). However, both then go straight on to introduce another role for names, as signs to the hearer of the speaker’s thoughts (Hobbes 1651, 4.3; Hobbes 1655, 2.2–5). And ‘signify’ appears to be the verb corresponding to what signs do. Though there are hints of this account in Leviathan, it is set out in most detail in De Corpore. There Hobbes says that names alone are not signs: “they are not signs except insofar as they are arranged in speech and are its parts” (Hobbes 1655, 2.3). So when we talk about signification, it’s the act of signifying, of communicating one’s thoughts by using words that are a sign of them, that is basic. In other terminology, while words name things, it’s utterances that have signification.
