Pyrrhonism is an ancient philosophical school founded by Pyrrho in the 4th century BCE. It emphasizes skepticism, advocating that one should suspend judgment on beliefs and opinions. Pyrrhonists argue that certainty is unattainable, and therefore, one should seek tranquility by accepting the limitations of knowledge. The core idea of Pyrrhonism is to achieve a state of mental peace through the practice of epoché, or withholding belief. This approach encourages individuals to remain open-minded and to recognize the relativity of perspectives, ultimately leading to a more serene and balanced life.
