The cannabis experience has greatly improved my appreciation for art, a subject which I had never much appreciated before,
The understanding of the intent of the artist which I can achieve when high sometimes carries over to when I’m down. This is one of many human frontiers which cannabis has helped me traverse.
The impediment to scientific thinking is not, I think, the difficulty of the subject. Complex intellectual feats have been mainstays even of oppressed cultures. Shamans, magicians and theologians are highly skilled in their intricate and arcane arts. No, the impediment is political and hierarchical.
In the fabric of space and in the nature of matter, as in a great work of art, there is, written small, the artist's signature.
Imagination will often carry us to worlds that never were. But without it we go nowhere.
We go about our daily lives understanding almost nothing of the world.
The secrets of evolution are death and time-the deaths of enormous numbers of lifeforms that were imperfectly adapted to the environment; and time for a long succession of small mutations.
When Kepler found his long-cherished belief did not agree with the most precise observation, he accepted the uncomfortable fact. He preferred the hard truth to his dearest illusions, that is the heart of science.
Science is merely an extremely powerful method of winnowing what's true from what feels good.
Our children long for realistic maps of the future that they can be proud of. Where are the cartographers of human purpose?
[N]o scientist likes to be criticized. ... But you don't reply to critics: "Wait a minute, wait a minute; this is a really good idea. I'm very fond of it. It's done you no harm. Please don't attack it." That's not the way it goes. The hard but just rule is that if the ideas don't work, you must throw them away. Don't waste any neurons on what doesn't work. Devote those neurons to new ideas that better explain the data. Valid criticism is doing you a favor.
We are an intelligent species and the use of our intelligence quite properly gives us pleasure. In this respect the brain is like a muscle. When we think well, we feel good. Understanding is a kind of ecstasy.
At the extremes it is difficult to distinguish pseudoscience from rigid, doctrinaire religion.
An atheist has to know more than I know. An atheist is someone who knows there is no God.
