In the following excerpt, Grant defends the "accuracy" of Thucydides's speeches, basing his argument on an examination of contemporary Greek notions of the purpose of public speech. He speculates that Thucydides believed that individuals in history were "there to reveal underlying causes " of the course of history; therefore, their speeches are not only vital to written history, but also are accurate inasmuch as they articulate those underlying causes.
