Socrates

Socrates served as a hoplite (heavy infantryman) in the Athenian army during the Peloponnesian War. He fought in the battles of Potidaea, Delium, and Amphipolis, where he was noted for his bravery and endurance, saving the life of Alcibiades at Potidaea.

Socrates developed a method of inquiry through questioning, known as the Socratic method. He engaged Athenians in dialogues to expose contradictions in their beliefs and stimulate critical thinking. This method became a cornerstone of Western philosophy and education.

During the reign of the Thirty Tyrants, Socrates was ordered to arrest Leon of Salamis for execution. He refused, risking his own life, because he considered the order unjust. This act demonstrated his commitment to moral principles over political authority.

Socrates was tried by an Athenian jury on charges of impiety and corrupting the youth. He was found guilty and sentenced to death by drinking hemlock. His refusal to escape and calm acceptance of death became a foundational example of philosophical integrity.
