Parfit was delighted by this discovery. He is in the business of searching for universal truths, so to find out that a figure like the Buddha, vastly removed from him by time and space, came independently to a similar conclusion—well, that was extremely reassuring. (Sometime later, he learned that “Reasons and Persons” was being memorized and chanted, along with sutras, by novice monks at a monastery in Tibet.) It is difficult to believe that there is no such thing as an all-or-nothing self—no “deep further fact” beyond the multitude of small psychological facts that make you who you are. Parfit finds that his own belief is unstable—he needs to re-convince himself. Buddha, too, thought that achieving this belief was very hard, though possible with much meditation.
