To be sane, he held, was either to be sedated by melancholy or activated by hysteria, two responses which were 'always and equally warranted for those of sound insight'. All others were irrational, merely symptoms of imaginations left idle, of memories out of work. And above these mundane responses, the only elevation allowable, the only valid transcendence, was a sardonic one: a bliss that annihilated the universe with jeers of dark joy, a mindful ecstasy. Anything else in the way of 'mysticism' was a sign of deviation or distraction, and a heresy to the obvious. (The Medusa)
