I would say Hobbes in particular is a complex and difficult and frankly eccentric thinker; don’t make the mistake of believing you understand him; he is weird. If you really want to grok the guy in the context of his culture and historical moment, you should just read Quentin Skinner. That’s hardcore intellectual history though; for the basics I’d just go for the clear and brief and informative Oxford Hobbes: A Very Short Introduction.
