The "Great Fool" of the Celts (Dalua) - Aleister Crowley in The Book of Toth

This is a considerable advance on those purely naturalistic phenomena above described; in the Great Fool is a definite doctrine. The world is always looking for a saviour, and the doctrine in question is philosophically more than a doctrine; it is a plain fact. Salvation, whatever salvation may mean, is not to be obtained on any reasonable terms. Reason is an impasse, reason is damnation; only madness, divine madness, offers an issue. The law of the Lord Chancelor will not serve; the law-giver may be an epileptic camel-driver like Mohammed, a megalomaniac provincial upstart like Napoleon, or even an exile, three-parts learned, one-part crazy, an attic-dweller in Soho, like Karl Marx. There is only one thing in common among such persons; they are all mad, that is, inspired. Nearly all primitive people posses this tradition, at least in a diluted form. They respect the wandering lunatic, for it may be that he is the messenger of the Most High. "This queer stranger? Let us entreat him kindly. It may be that we entertain an angel unawares."
