Daily Inspiration Quote by Timothy Leary

"There are three side effects of acid: enhanced long-term memory, decreased short-term memory, and I forget the third"

About this Quote

Leary’s line is a tidy hall of mirrors: it performs the very cognitive glitch it claims to diagnose. The joke lands because it borrows the voice of scientific enumeration (three side effects, neatly itemized) and then sabotages it with a punchline that’s also a symptom. That self-undermining cadence is pure Leary: the former Harvard psychologist turned psychedelic evangelist, always halfway between lab coat and carnival barker, using wit as a delivery system for provocation.

The specific intent isn’t to offer pharmacology; it’s to puncture the era’s competing certainties about LSD. In the 1960s, acid was sold as both miracle and menace: a mind-expander in counterculture lore, a brain-fryer in mainstream panic. Leary splits the difference with a smirk. “Enhanced long-term memory” nods to the grand claims - insight, revelation, permanent perspective shifts - while “decreased short-term memory” admits the mundane cost: the immediate disorientation, the dropped thread, the lost sentence. Then he drops the thread on purpose. Comedy becomes demonstration.

Subtextually, it’s also an argument about authority. By making the “educator” forget his own list, Leary mocks the expectation that altered states can be cleanly categorized, measured, and certified by experts. The gag implies that the psychedelic experience resists the bureaucratic impulse to summarize it into bullet points. Context matters: this is post-psychedelic boom, amid criminalization and cultural backlash, when Leary’s persona needed to be both disarming and defiant. He turns impairment into charisma, and the punchline into a wink at anyone who’s tried to explain acid and watched language dissolve mid-explanation.
