Quote by Thucydides: “A man who has the power to act and will not, is not a man.”

This statement reflects a belief in the necessity of action, particularly for those in positions of power. It suggests that true manhood or leadership involves utilizing one's capabilities to make decisions and implement them. Failing to act when one possesses the means is seen as a dereliction of duty.

Thucydides' analysis of the Peloponnesian War often scrutinizes leadership and decision-making during crisis. This quote might reflect the ancient Greek emphasis on civic duty and the expectation for leaders to be decisive, especially in matters of war and state policy.

Athenian general and historian who lived approximately 460–400 BCE and wrote The History of the Peloponnesian War. He is considered the first truly analytical historian, distinguishing between cause and pretext and prioritizing evidence over mythology. His work profoundly shaped how we understand war and politics.
