Ancient Greek Philosophy: Plato and Aristotle
Plato
Plato’s philosophy explores the world’s nature and the problems of humanity, including political, social, metaphysical, epistemological, anthropological, and moral-political issues. He aimed to understand the essence of things, the possibility of knowing that essence, human nature, and the ideal society.
