Socrates—Socrates (470-399 BC) is the most influential philosopher in the recorded history of the Western world. Plato was his disciple and Aristotle his grand-disciple. Socrates lived in Athens and taught a doctrine of the soul that is similar in many ways to the Vedic conception. In a 1966 Bhagavad-gītā lecture, Śrīla Prabhupāda said Socrates was a mukta-puruṣa (a liberated soul). According to his biographer Plato, Socrates was unjustly convicted for anti-state activities by the Athenean authorities, who ordered him drink poison. He did so cheerfully, and died preaching we are not these bodies to his followers.
