- The 1990s brought a quiet groundswell of second-wave interest in psychedelics — a resurgence that culminated with a 2006 paper reporting on studies at Johns Hopkins, which had found that psilocybin had occasioned “mystical-type experiences having substantial and sustained personal meaning and significance” for terminally ill cancer patients — experiences from which they “return with a new perspective and profound acceptance.” In other words, the humble mushroom compound had helped people face the ultimate frontier of existence — their own mortality — with unparalleled equanimity. The basis of the experience, researchers found, was a sense of the dissolution of the personal ego, followed by a sense of becoming one with the universe — a notion strikingly similar to Bertrand Russell’s insistence that a fulfilling life and a rewarding old age are a matter of “[making] your interests gradually wider and more impersonal, until bit by bit the walls of the ego recede, and your life becomes increasingly merged in the universal life.
More clinical experiments followed at UCLA, NYU, and other leading universities, demonstrating that this psilocybin-induced dissolution of the ego, extremely difficult if not impossible to achieve in our ordinary consciousness, has profound benefits in rewiring the faulty mental mechanisms responsible for disorders like alcoholism, anxiety, and depression.
This renaissance of psychedelics, with its broad implications for understanding consciousness and the connection between brain and mind, treating mental illness, and recalibrating our relationship with the finitude of our existence, is what Michael Pollan explores in the revelatory How to Change Your Mind: What the New Science of Psychedelics Teaches Us About Consciousness, Dying, Addiction, Depression, and Transcendence.
