International problems are not reducible to economic and social conjuncture. Thucydides therefore focuses on events, particular human acts performed freely-chosen, and thus themselves irreducible to junctures of forces. No twentieth-century Thucydides could exist; no intelligible account of the wars of the present century could omit references to actors, but they would not be of central interpretative importance. Modern events are disindividualized, modern collective decisions numerous and complex. Thucydides nevertheless remains significant today to those unwilling to view events divorced from the action of individuals. As an historian Thucydides experienced a feeling of destiny looking back upon free actions, but still held that they alone merit attention.
