Greek philosophers were "seekers and lovers of wisdom". They studied and analyzed the world around them using logic and reason. Although we often think of philosophy as religion or "the meaning of life", the Greek philosophers were also scientists. Many studied mathematics and physics as well.
Socrates and Plato are two famous Greek philosophers whose ideas still impact society today. In ancient Greece, philosophers contemplated and theorized about many different ideas such as human nature, ethics, and moral dilemmas.
