“Friendship is the only cement that will ever hold the world together.”

“You have the greatest soul, the noblest nature, the sweetest, most loving heart I have ever known, and my love, my reverence, my admiration for you, you have increased in one evening as I should have thought only a lifetime of intimate, loving association could have increased them. You are more wonderful and lovely in my eyes than you ever were before; and my pride and joy and gratitude that you should love me with such a perfect love are beyond all expression, except in some great poem which I cannot write.”

“You are here in order to enable the world to live more amply, with greater vision, with a finer spirit of hope and achievement. You are here to enrich the world.”

“We are citizens of the world. The tragedy of our times is that we do not know this.”

“You are not here merely to make a living. You are here in order to enable the world to live more amply, with greater vision, with a finer spirit of hope and achievement. You are here to enrich the world, and you impoverish yourself if you forget the errand.”

“Only peace between equals can last.”

“I not only use all the brains that I have, but all I can borrow.”
