Guilt is a rope that wears thin.

Love is an expression and assertion of self-esteem, a response to one's own values in the person of another. One gains a profoundly personal, selfish joy from the mere existence of the person one loves. It is one's own personal, selfish happiness that one seeks, earns, and derives from love.

Integrity is the recognition of the fact that you cannot fake your consciousness, just as honesty is the recognition of the fact that you cannot fake existence.

Humor is not an unconditional virtue; its moral character depends on its object. To laugh at the contemptible, is a virtue; to laugh at the good, is a hideous vice. Too often, humor is used as the camouflage of moral cowardice.

Live and act within the limit of your knowledge and keep expanding it to the limit of your life. Redeem your mind from the hockshops of authority. Accept the fact that you are not omniscient, but playing a zombie will not give you omniscience-that your mind is fallible, but becoming mindless will not make you infallible-that an error made on your own is safer than ten truths accepted on faith, because the first leaves you the means to correct it, but the second destroys your capacity to distinguish truth from error.

An idea is a light turned on in a man's soul. Comic-strip artists are in the habit of representing it by means of a light bulb flashing on, above the head of a character who has suddenly grasped an idea. In simple, primitive terms, this is an appropriate symbol.

An honest man is one who knows that he can't consume more than he has produced.
