Critical evaluations

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. Indeed, several passages of Thucydides' book are written "with an intensity of feeling hardly exceeded by Sappho herself."

In his Open Society and Its Enemies, Karl R. Popper writes that Thucydides was the "greatest historian, perhaps, who ever lived." Thucydides' work, however, 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' "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."
