"The true happiness of man consists in the perfection of his intellect."

"The purpose of the entire Torah is to bring man to this perfection."

"He who thinks that he can attain the perfection of man without the help of God, errs greatly."

"A man should always consider himself as half meritorious and half guilty."

"The world is a ladder, and man is at the bottom. He can ascend, or he can descend."
