Science was born as a result and consequence of philosophy; it cannot survive without a philosophical base. If philosophy perishes, science will be next to go.

Rationalization is a cover-up, a process of providing one's emotions with a false identity, of giving them spurious explanations and justifications - in order to hide one's motives, not just from others, but primarily from oneself. The price of rationalizing is the hampering, the distortion, and, ultimately, the destruction of one's cognitive faculty. Rationalization is a process not of perceiving reality, but of attempting to make reality fit one's emotions.

Happiness is a state of non-contradictory joy--a joy without penalty or guilt, a joy that does not clash with any of your values and does not work for your own destruction, not the joy of escaping from your mind, but of using your mind's fullest power, not the joy of faking reality, but of achieving values that are real, not the joy of a drunkard, but of a producer.

The pressure disappeared with the first word he put on paper. He thought--while his hand moved rapidly--what a power there was in words; later, for those who heard them, but first for the one who found them; a healing power, a solution, like the breaking of a barrier. He thought, perhaps the basic secret the scientists have not discovered, the first fount of life, is that which happens when a thought takes shape in words.

"You were not born to be a second-hander." Howard Roark to Gail Wynand in "The Fountainhead"

Since reason is man’s basic means of survival, that which is proper to the life of a rational being is the good; that which negates, opposes or destroys it is the evil.

We'll meet again. We'll meet when years have passed, and years make such a difference, don't they?
