"The wise man knows nothing if he..." - Quote by Marcus Tullius Cicero

“There exists a law, not written down anywhere but inborn in our hearts; a law which comes to us not by training or custom or reading but by derivation and absorption and adoption from nature itself; a law which has come to us not from theory but from practice, not by instruction but by natural intuition. I refer to the law which lays it down that, if our lives are endangered by plots or violence or armed robbers or enemies, any and every method of protecting ourselves is morally right.”

“The higher our position the more modestly we should behave.”

“Loyalty is what we seek in friendship.”

“Always take hold of things by the smooth handle.”

“Whenever we attempt to mend the scheme of Providence and to interfere in the Government of the world, we had need be very circumspect lest we do more harm than good.”

“Water in the boat is the ruin of the boat, but water under the boat is its support.”

“He that breaks a thing to find out what it is has left the path of wisdom.”

“The light which puts out our eyes is darkness to us.”

“To the ignorant, even the words of wise seem foolishness.”
