Strauss, Leo. "On Thucydides' War of the Peloponnesians and the Athenians." Chap. 3 in The City and Man. Chicago: University of Chicago Press, 1978. First published 1964 by the University Press of Virginia.
The City and Man consists of provocative essays by the late Leo Strauss on Aristotle’s Politics, Plato’s Republic, and Thucydides’ Peloponnesian Wars. Together, the essays constitute a brilliant attempt to use classical political philosophy as a means of liberating modern political philosophy from the stranglehold of ideology. The essays are based on a long and intimate familiarity with the works, but the essay on Aristotle is especially important as one of Strauss’s few writings on the philosopher who largely shaped Strauss’s conception of antiquity. The essay on Plato is a full-scale discussion of Platonic political philosophy, wide in scope yet compact in execution. When discussing Thucydides, Strauss succeeds not only in presenting the historian as a moral thinker of high rank, but in drawing his thought into the orbit of philosophy, and thus indicating a relation of history and philosophy that does not presuppose the absorption of philosophy by history.
