“There is no more radical cure than Thucydides for the lamentably rose-coloured idealisation of the Greeks which the “classically-cultured” stripling bears with him into life, as a reward for his public school training. His writings must be carefully studied line by line, and his unuttered thoughts must be read as distinctly as what he actually says. There are few thinkers so rich in unuttered thoughts… Greek philosophy is the decadence of the Greek instinct: Thucydides is the great summing up, the final manifestation of that strong, severe positivism which lay in the instincts of the ancient Hellene. After all, it is courage in the face of reality that distinguishes such natures as Thucydides from Plato: Plato is a coward in the face of reality—consequently he takes refuge in the ideal: Thucydides is master of himself,—consequently he is able to master life.”
