"Friendship is unnecessary, like philosophy, like art. It has no survival value; rather it is one of those things which give value to survival."

"What draws people to be friends is that they see the same truth. They share it."

"Do not let us mistake necessary evils for good."

"Friendship is born at the moment when one man says to another "What! You too? I thought that no one but myself."

"We live, in fact, in a world starved for solitude, silence, and private: and therefore starved for meditation and true friendship."

"A second chance doesn't mean anything if you haven't learned from your first mistake."
