“Use them with care, and use them with respect as to the transformations they can achieve, and you have an extraordinary research tool. Go banging about with a psychedelic drug for a Saturday night turn-on, and you can get into a really bad place, psychologically. Know what you're using, decide just why you're using it, and you can have a rich experience. They're not addictive, and they're certainly not escapist, either, but they're exceptionally valuable tools for understanding the human mind, and how it works.”

“Lies are neither bad nor good. Like a fire they can either keep you warm or burn you to death, depending on how they're used.”

“...are you a person with volition and maybe some stubbornness and at least the capacity if not the actual determination to do something surpring or are you a tool? A tool just serves it's user, and it's not good for anything else. So if you want to accomplich something special -something more than you can do for yourself - you can't use a tool. You have to use a person and hope the surprises will work in your favor. You have to use something that's free to not be what you had in mind.”

“What traitors books can be! You think they're backing you up, and they turn on you. Others can use them, too, and there you are, lost in the middle of the moor, in a great welter of nouns and verbs and adjectives.”

“I understand the arguments about how the billions of dollars spent to put men on the moon could have been used to fight poverty and hunger on Earth. But, look, I'm a scientist who sees inspiration as the ultimate tool for doing good. When you use money to fight poverty, it can be of great value, but too often, you're working at the margins. When you're putting people on the moon, you're inspiring all of us to achieve the maximum of human potential, which is how our greatest problems will eventually be solved. Give yourself permission to dream.”
