Self-esteem is reliance on ones power to think.

Man has a single basic choice: to think or not, and that is the gauge of his virtue. Moral perfection is an unbreached rationality-not the degree of your intelligence, but the full and relentless use of your mind, not the extent of your knowledge, but the acceptance of reason as an absolute.

Observe how many people evade, rationalize and drive their minds into a state of blind stupor, in dread of discovering that those they deal with- their "loved ones" or friends or business associates or political rulers- are not merely mistaken, but evil. Observe that this dread leads them to sanction, to help and to spread the very evil whose existence they fear to acknowledge.

When man learns to understand and control his own behavior as well as he is learning to understand and control the behavior of crop plants and domestic animals, he may be justified in believing that he has become civilized.

Live and act within the limit of your knowledge and keep expanding it to the limit of your life.

I love you, Dominique. As selfishly as the fact that I exist. As selfishly as my lungs breathe air. I breathe for my own necessity, for the fuel of my body, for my survival. I've given you, not my sacrifice or my pity, but my ego and my naked need. This is the only way I can want you to love me.

Because, you see, God - whatever anyone chooses to call God - is one's highest conception of the highest possible. And whoever places his highest conception above his own possibility thinks very little of himself and his life. It's a rare gift, you know, to feel reverence for your own life and to want the best, the greatest, the highest possible, here, now, for your very own. To imagine a heaven and then not to dream of it, but to demand it.
