I am 100 percent in favor of the intelligent use of drugs, and 1,000 percent against the thoughtless use of them, whether caffeine or LSD. And drugs are not central to my life.

Hippies started the ecology movement. They combated racism. They liberated sexual stereotypes, encouraged change, individual pride, and self-confidence. They questioned robot materialism.

The aim of human life is to know thyself. Think for yourself. Question authority. Think with your friends. Create, create new realities. Philosophy is a team sport. Philosophy is the ultimate, the ultimate aphrodisiac pleasure. Learning how to operate your brain, learning how to operate your mind, learning how to redesign chaos

The PC is the LSD of the '90s.
