From: Isidore of Pelusium, monk
To: Ophelius the Grammarian
Date: ~410 AD
Context: Isidore surveys the ancient philosophers' definitions of philosophy and offers a Christian definition that supersedes them all.
The other philosophers defined philosophy as the art of arts and the science of sciences. Pythagoras defined it as zeal for wisdom. Plato, as acquisition of the sciences. Chrysippus, as the practice of correctness in speech. Even among those who are thought to be the supreme thinkers, the definitions come out roughly the same.
Our definition is different. We define true philosophy as that which neglects nothing that leads toward piety and virtue. Not art, not science, not verbal precision — though these have their place — but the life that never turns away from what matters most. Any other definition of philosophy is a philosophy about philosophy. Ours is philosophy put to use.
