Some lose all mind and become soul: insane. Some lose all soul and become mind: intellectual. Some lose both and become: accepted.
So man’s insanity is heaven’s sense; and wandering from all mortal reason, man comes at last to that celestial thought, which, to reason, is absurd and frantic; and weal or woe, feels then uncompromised, indifferent as his God.
Perhaps if you know you are insane then you are not insane. Or you are becoming sane, finally. Waking up.
Knowing was the worst part. Awareness of insanity does not make one any less insane. Awareness of drowning does not make one any less of a drowning person—it only adds the burden of panic.
Insanity in individuals is something rare — but in groups, parties, nations, and epochs it is the rule.
