The necessary unity of power and wisdom is only a coincidence for the ancients, i.e., dependent on chance completely out of the philosophers control. Knowledge is not in itself power, and though it is not in itself vulnerable to power, those who seek it and possess it most certainly are. Therefore the great virtue for the philosophers in their political deeds was moderation. They were utterly dependent on the prejudices of the powerful and had to treat them most delicately.
