There are also clear heroes and villains in Thucydides’ history. To a modern audience steeped in the behavioral and social sciences, Thucydides can appear to miss nuances in human temperament, concentrating instead on “objective” and absolute criteria such as timidity and heroism or recklessness versus self-control. In his eyes, human behavior is not predicated on or explained by one’s specific environment or upbringing, but instead directed by the play of chance, fate, and hope upon innate character—conditions universal to all and particular to no man.
