Ethics in Thucydides uses the historian's account of the resolution at Corcyra as the basis for determining a moral or ethical perspective in Thucydides'History. Various scenes, speeches, and narrative descriptions are analyzed in relation to ethical vocabulary, their conformity to an ethical perspective, and the way in which they promote an ethical outcome. Ethics in Thucydides is ground-breaking because up to this point, scholars have not persuasively argued that ethics played a role in History. Williams' work is an extensive analysis which also considers Thucydides in relation to his predecessors and contemporaries.
