This document discusses the power and limitations of human reason. It begins by praising reason as what separates humans from other animals, according to philosophers like Pythagoras, Socrates, and Aristotle. However, it then notes the limitations of reason, giving examples like paradoxes and Protagoras' student's dilemma that show logical ambiguities. While reason is necessary for society, absolute knowledge is beyond human capacity. Therefore, reason alone cannot determine universal moral standards, and we are left relying on legal standards.
