“Taking LSD was a profound experience, one of the most important things in my life. LSD shows you that there’s﻿ another side to the coin, and you can’t remember it when it wears off, but you know it. It reinforced my sense of what was important—creating great things instead of making money, putting things back into the stream of history and of human consciousness as much as I could.”
― Steve Jobs

“Jobs had begun to drop acid by then, and he turned Brennan on to it as well, in a wheat field just outside Sunnyvale. "It was great," he recalled. "I had been listening to a lot of Bach. All of a sudden the whole field was playing Bach. It was the most wonderful feeling of my life up to that point. I felt like the conductor of this symphony with Bach coming through the wheat.”
― Walter Isaacson

"I believe that with the advent of acid, we discovered a new way to think, and it has to do with piecing together new thoughts in your mind. Why is it that people think it's so evil? What is it about it that scares people so deeply, even the guy that invented it, what is it? Because they're afraid that there's more to reality than they have confronted. That there are doors that they're afraid to go in, and they don't want us to go in there either, because if we go in we might learn something that they don't know. And that makes us a little out of their control."
--Ken Kesey

"'Turn on' meant go within to activate your neural and genetic equipment. Become sensitive to the many and various levels of consciousness and the specific triggers that engage them. Drugs were one way to accomplish this end. 'Tune in' meant interact harmoniously with the world around you—externalize, materialize, express your new internal perspectives. Drop out suggested an elective, selective, graceful process of detachment from involuntary or unconscious commitments. 'Drop Out' meant self-reliance, a discovery of one's singularity, a commitment to mobility, choice, and change. Unhappily my explanations of this sequence of personal development were often misinterpreted to mean 'Get stoned and abandon all constructive activity.'"
--Tim Leary

Deliberate provocation of mystical experience, particularly by LSD and related hallucinogens, in contrast to spontaneous visionary experiences, entails dangers that must not be underestimated. Practitioners must take into account the peculiar effects of these substances, namely their ability to influence our consciousness, the innermost essence of our being. The history of LSD to date amply demonstrates the catastrophic consequences that can ensue when its profound effect is misjudged and the substance is mistaken for a pleasure drug. Special internal and external advance preparations are required; with them, an LSD experiment can become a meaningful experience. Wrong and inappropriate use has caused LSD to become my problem child.
--Dr. Albert Hofmann

Woz and I very much liked Bob Dylan's poetry, and we spent a lot of time thinking about a lot of that stuff. This was California. You could get LSD fresh made from Stanford. You could sleep on the beach at night with your girlfriend. California has a sense of experimentation and a sense of openness—openness to new possibilities.
--Steve Jobs

PLAYBOY: Ever take LSD?
GATES: My errant youth ended a long time ago.
PLAYBOY: What does that mean?
GATES: That means there were things I did under the age of 25 that I ended up not doing subsequently.
PLAYBOY: One LSD story involved you staring at a table and thinking the corner was going to plunge into your eye.
GATES: [Smiles]
PLAYBOY: Ah, a glimmer of recognition.
GATES: That was on the other side of that boundary. The young mind can deal with certain kinds of gooping around that I don't think at this age I could. I don't think you're as capable of handling lack of sleep or whatever challenges you throw at your body as you get older. However, I never missed a day of work.

Thinking differently--or learning to Think Different, as a Jobs slogan has it--is a hallmark of the acid experience. "When I'm on LSD and hearing something that's pure rhythm, it takes me to another world and into anther brain state where I've stopped thinking and started knowing," Kevin Herbert told Wired magazine at a symposium commemorating Hofmann's one hundredth birthday. Herbert, an early employee of Cisco Systems who successfully banned drug testing of technologists at the company, reportedly "solved his toughest technical problems while tripping to drum solos by the Grateful Dead."

“I really feel like Mike Judge has never been to Burning Man, which is Silicon Valley,” opined Musk. “If you haven’t been, you just don’t get it. You could take the craziest L.A. party and multiply it by a thousand, and it doesn’t even get fucking close to what’s in Silicon Valley. The show didn’t have any of that.”

“If the words 'life, liberty, and the pursuit of happiness' don't include the right to experiment with your own consciousness, then the Declaration of Independence isn't worth the hemp it was written on.”

“Psychedelics are illegal not because a loving government is concerned that you may jump out of a third story window. Psychedelics are illegal because they dissolve opinion structures and culturally laid down models of behaviour and information processing. They open you up to the possibility that everything you know is wrong.”
― Terence McKenna

“You have to take seriously the notion that understanding the universe is your responsibility, because the only understanding of the universe that will be useful to you is your own understanding.”
