Mattis questions 'silly' as the right word to describe LSD as a tool of understanding. In the original post I was mocking more my old boss's Jungian enthusiasm than the use of the drug itself. In my own rather limited experiences with it, the one insight which I still feel I should never otherwise have gained was into the subjective nature of time. There's nothing very taxing intellectually about imagining oneself standing 'outside of time' & I had never thought all that much about it. But, undeniably, under the drug I did have that sudden click of understanding for which we use the word 'insight'. (Not so much a click, actually, more an intergalactic boom. Terrifying at the time, strangely reassuring in retrospect.) At the more personal level I remain doubtful that the supervivid kaleidoscope of colours, snakes, Grecian friezes & so on, shed any more light on my own individual story than the figures that emerged from other - less exotically triggered - deliriums. I'm afraid it took the hard old slog of lying on the couch in Maresfield Gardens arguing the toss over several years with myself & Mrs Burlingham before the real pennies began to drop. This obviously reflects a personal predisposition. I'm very glad to have had that particular glimpse behind the curtain. And I suspect I might have gained similar experiences from following the various Christian or Buddhist mystical disciplines. My trouble is: I find them really quite boring & - secretly - kind of irrelevant. Even at this advanced age when I should be thinking of higher things, I'm much more intrigued to understand what the hell is going on behind the eyes of my wife. How did the undercarriage retraction system work on the Hawker Hurricane? To what extent is this drunk exaggerating his alcohol intake? How *did* old Hem convey that feeling at the start of a hot summer morning? And so on. Which no doubt explains my ambivalence about the later Salinger, the Buddhist version. Scottie B. the Buddhist.
