One must differentiate between one's thoughts and one's emotions with full clarity and precision...No discussion, cooperation, agreement, or understanding is possible among men who substitute emotion for proof.

If capitalism had never existed, any honest humanitarian should have been struggling to invent it. But when you see men struggling to evade its existence, to misrepresent its nature, and to destroy its last remnants - you maybe sure that whatever their motives, love of man is not one of them.

It's strange. There's your life. You begin it, feeling that it's something so precious and rare, so beautiful that it's like a sacred treasure. Now it's over, and it doesn't make any difference to anyone, and it isn't that they are indifferent, it's just that they don't know, they don't know what it means, that treasure of mine, and there's something about it that they should understand.

No matter how vast your knowledge or how modest, it is your own mind that has to acquire it. It is only with your own knowledge that you can deal. It is only your own knowledge that you can claim to possess or ask others to consider. Your mind is your only judge of truth - and if others dissent from your verdict, reality is the court of final appeal. Nothing but a man's mind can perform that complex, delicate, crucial process of identification which is thinking. Nothing can direct the process but his own judgment. Nothing can direct his judgment but his moral integrity.
