“It contributes greatly towards a man's moral and intellectual health, to be brought into habits of companionship with individuals unlike himself, who care little for his pursuits, and whose sphere and abilities he must go out of himself to appreciate.”

“A man, to be greatly good, must imagine intensely and comprehensively; he must put himself in the place of another and many others; the pains and pleasures of his species must become his own. The great instrument of moral good is the imagination.”

“If we are to survive, we must have ideas, vision, and courage. These things are rarely produced by committees. Everything that matters in our intellectual and moral life begins with an individual confronting his own mind and conscience in a room by himself.”

“Man—every man—is an end in himself, not a means to the ends of others; he must live for his own sake, neither sacrificing himself to others nor sacrificing others to himself; he must work for his rational self-interest, with the achievement of his own happiness as the highest moral purpose of his life.”

“Every man hath the right to doubt his task, and to forsake it from time to time; but what he must not do is forget it. Whoever doubteth not himself is unworthy-- for in his unquestioning belief in his ability, he commiteth the sin of pride. Blessed are they who go through moments of indecision.”

“Everyone carries a part of society on his shoulders; no one is relieved of his share of responsibility by others. And no one can find a safe way out for himself if society is sweeping toward destruction. Therefore, everyone, in his own interests, must thrust himself vigorously into the intellectual battle. None can stand aside with unconcern; the interest of everyone hangs on the result. Whether he chooses or not, every man is drawn into the great historical struggle, the decisive battle into which our epoch has plunged us.”
