"This is intellectual suicide—the total destruction of thought—to such a degree that even the rationalist's own concepts of mechanism, unconscious process, statistical necessity, and the like, also become purely arbitrary and meaningless terms. To hold such a view of the universe consistently, one must separate oneself, the observer, from it. But this cannot be done, for which reason a contemporary philosopher has complained that man's subjective presence constitutes the greatest obstacle to philosophical knowledge!"

— Alan Watts, Behold the Spirit
