“In the final analysis, what stands out about Thucydides is not his weaknesses but his strengths as a historian. We note his omissions, but no account of the Peloponnesian War or of fifth-century Greece in general is more complete. Some scholars worry over his cut-and-dried heroes and villains. But is there much evidence to suggest that these assessments were fundamentally wrong? Others argue that his speeches are biased distortions, but no one can prove that any are outright fabrications.”
