Salvation, whatever salvation may mean, is not to be obtained by any reasonable terms. Reason is an impasse, reason is damnation; only madness, divine madness, offers an issue. The law of the Lord Chancellor 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.
