a narrative". In this view, the blind and immoderate behaviour of the Athenians (and indeed of all the other actors)—although perhaps intrinsic to human nature—leads to their downfall. Thus his History could serve as a warning to leaders to be more prudent, by putting them on notice that someone would be scrutinizing their actions with a historian's objectivity rather than a chronicler's flattery. The historian J. B. Bury writes that the work of Thucydides "marks the longest and most decisive step that has ever been taken by a single man towards making history what it is today". Historian H. D. Kitto feels that Thucydides wrote about the Peloponnesian War, not because it was the most significant war in antiquity but because it caused the most suffering. Several passages of Thucydides's book are written "with an intensity of feeling hardly exceeded by Sappho herself". In his book The Open Society and Its Enemies, Karl Popper writes that Thucydides was the "greatest historian, perhaps, who ever lived". Thucydides's work, Popper goes on to say, represents "an interpretation, a point of view; and in this we need not agree with him". In the war between Athenian democracy and the "arrested oligarchic tribalism of Sparta", we must never forget Thucydides's "involuntary bias", and that "his heart was not with Athens, his native city." Although he apparently did not belong to the extreme wing of the Athenian oligarchic clubs who conspired throughout the war with the enemy, he was certainly a member of the oligarchic party, and a friend neither of the Athenian people, the demos, who had exiled him, nor of its imperialist policy. Comparison with Herodotus Thucydides and his immediate predecessor, Herodotus, both exerted a significant influence on Western historiography. Thucydides does not mention his counterpart by name, but his famous introductory statement is thought to refer to him:To hear this history rehearsed, for that there be inserted in it no fables, shall be perhaps not delightful. But he that desires to look into the truth of things done, and which (according to the condition of humanity) may be done again, or at least their like, shall find enough herein to make him think it profitable. And it is compiled rather for an everlasting possession than to be rehearsed for a prize. (1:22) Herodotus records in his Histories not only the events of the Persian Wars, but also geographical and ethnographical information, as
