Fate and Human Agency

The interplay between chance events (like the plague or storms) and deliberate human action is a recurring theme, with characters often debating whether outcomes are determined by fortune, divine will, or their own choices.

Thucydides emphasizes human actions—migrations, alliances, naval development—over divine intervention, and critiques uncritical acceptance of tradition.

Natural disasters (plague, earthquakes, tidal waves) are presented as forces beyond human control that shape the course of the war.

The Melians place their hope in fortune, the gods, and Spartan intervention, while the Athenians warn against relying on hope when resources are insufficient.

The Athenians' inability to act decisively after the failed attack underscores the tension between human planning and the unfolding of events beyond their control.
