“The best ideas will eat at you for days, maybe even weeks, until something, some incident, some impulse, triggers you to finally express them.”

“The lampshade on my head is for my bright ideas. I won’t be able to convey them until Monday, when my curtain gets out of the dry cleaners.”

“Ideas and philosophies have a shelf-life. They must be kept fresh and renewed or they will spoil. If left unattended, the same ideas and philosophies that once nourished you and helped you grow can poison you and make you sick. Become aware of new ideas that can refresh your way of life and be open to the fact that your old ideas and philosophies can work for you for some time, but when the shelf-life has passed, those ideas and philosophies could also harm you.”

“A writer is one who communicates ideas and emotions people want to communicate but aren’t quite sure how, or even if, they should communicate them.”

“Each voice carries a portion of value, no matter how unpalatable or distasteful that voice may be: no one person, government, ideology, transnational, or religious institution can own and dominate the whole.”

“Ownership is not limited to material things. It can also apply to points of view. Once we take ownership of an idea — whether it’s about politics or sports — what do we do? We love it perhaps more than we should. We prize it more than it is worth. And most frequently, we have trouble letting go of it because we can’t stand the idea of its loss. What are we left with then? An ideology — rigid and unyielding.”

“Whenever I think of something but can’t think of what it was I was thinking of, I can’t stop thinking until I think I’m thinking of it again. I think I think too much.”

“I can’t understand why people are frightened of new ideas. I’m frightened of the old ones.”

“A man may die, nations may rise and fall, but an idea lives on. Ideas have endurance without death.”

“On no subject are our ideas more warped and pitiable than on death. … Let children walk with nature, let them see the beautiful blendings and communions of death and life, their joyous inseparable unity, as taught in woods and meadows, plains and mountains and streams of our blessed star, and they will learn that death is stingless indeed, and as beautiful as life, and that the grave has no victory, for it never fights.”

“I like the scientific spirit—the holding off, the being sure but not too sure, the willingness to surrender ideas when the evidence is against them: this is ultimately fine—it always keeps the way beyond open—always gives life, thought, affection, the whole man, a chance to try over again after a mistake—after a wrong guess.”
