"The truth is that religion, as we speak of it – Islam, Christianity, Judaism – is based on the claim that God dictates certain books. He doesn’t code software, he doesn’t produce films, he doesn’t score symphonies, he is an author. And this claim has achieved credibility because these books are deemed so profound they could not have possibly been written by human authors. Please consider for a moment how differently we treat scientific claims and texts and discoveries. Isaac Newton went into isolation for 18 months starting in the year 1665. When he came out of his solitude he had invented the calculus; he had discovered the laws of motion and universal gravitation; he had single-handedly created the field of optics. No one thinks this was anything but a man’s labor. And it took 200 hundred years of continuous ingenuity on the part of some of the smartest people who ever lived to substantially improve upon Newton’s work. How difficult would it be to improve the Bible? Anyone in this room could improve this supposedly inerrant text scientifically, historically, ethically, spiritually – in moments. If God loves us and wanted to guide us with a book of morality, it’s very strange to have given us a book that supports slavery, that demands that we murder people for imaginary crimes like witchcraft. The true basis for hope in our world is open-ended conversation, and religion has shattered our world into competing moral communities. What we have to convince ourselves of is – that love and curiosity is enough for us – and intellectual honesty is the guardian of that."

“Needless to say, if I knew my daughter would eventually develop a fondness for methamphetamine or crack cocaine, I might never sleep again. But if she does not try a psychedelic like psilocybin or LSD at least once in her adult life, I will worry that she may have missed one of the most important rites of passage a human being can experience.”

“Happiness and suffering, however extreme, are mental events. The mind depends upon the body, and the body upon the world, but everything good or bad that happens in your life must appear in consciousness to matter. This fact offers ample opportunity to make the best of bad situations—changing your perception of the world is often as good as changing the world—but it also allows a person to be miserable even when all the material and social conditions for happiness have been met. During the normal course of events, your mind will determine the quality of your life.”

“Honesty is a gift we can give to others. It is also a source of power and an engine of simplicity. Knowing that we will attempt to tell the truth, whatever the circumstances, leaves us with little to prepare for. We can simply be ourselves.”

“The connection between facts and values is straightforward and philosophically uninteresting... values reduce to facts about the well-being of conscious creatures; the well-being of conscious creatures is what can be valued in this universe... Now, here’s the one bit of philosophy I’m going to anchor this to: imagine a universe in which every conscious creature suffers as much as it can for as long as it can – I call this the worst possible misery for everyone. The worst possible misery for everyone is bad. If the word bad is to mean anything, surely it applies to the worst possible misery for everyone... the moment you grant me that the worst possible misery for everyone is bad and therefore worth avoiding... well then you have every other possible constellation of conscious experience which, by definition, is better. So you have this continuum here of states of consciousness and given that consciousness is related to the way the universe is, it’s constrained by the laws of nature in some way, there are going to be right and wrong ways to move along this continuum... now this is, in philosophy, a somewhat controversial statement. I do not see how.”

“I think it should be like getting a pilot's license. I think you should require training to get a license to have a gun.”
