This chapter looks at the similarities and differences between Thucydides and Hobbes on the subject of regimes. Hobbes was convinced that Thucydides had proved the absurdity of democracy and the desirability of absolute monarchy. However, Hobbes misread Thucydides on this point. For Hobbes, monarchy was the only regime in which the selfish interests of the ruler and ruled rationally coincide. Revealingly, in order to deal with the leadership of Pericles, Hobbes had to characterize him superficially as a monarch, ignoring how Pericles won and maintained his power. But it is just the type of statesmanship exemplified by Pericles that Hobbes cannot accept because of his rigid assumptions about human nature. Thucydides' focus on the importance of studying the thought, character, and actions of statesmen is an important difference between the Thucydidean and the Hobbesian realist models. Hobbes's horror at civil violence led him to lose faith in ordinary human reason and thus in political deliberation. It is because he lost faith in the latter that scientific reason emerged as a powerful alternative. But if human beings are so unreasonable that one can no longer take seriously what they say, how can one expect them to be reasonable enough to accept Hobbes's prescriptions? The Hobbesian solution is that an absolute government must enforce the plan. The chapter then argues that this solution to political problems is even more dangerous than the Thucydidean solution, which relies on political rhetoric and judgment.
