Plutarch was a Greek philosopher who lived from 46 to 127 CE. He is best known for his biographies of famous people, but he also wrote extensively on philosophy. Plutarch's philosophy was based on Middle Platonism, which was a school of thought that combined Platonic philosophy with Stoic and Aristotelian ideas. Middle Platonism was popular in the Roman Empire, and it had a significant influence on Christian thought.
