"In point of fact there are two kinds sorts of mysticism, differing from one another as the ranting of drunkards from the language of illumined spirits. There is the muddled, stammering mysticism, and there is the mysticism luminous with truly ultimate ideas. On the one hand there are the empty dimness and darkness, the barren, chilling sentimentalism and mental debauchery, the foolishly grimacing but rigid phantasms of the Cabbala, of occultism, mysteriosophy and theosophy. We cannot draw too sharp a dividing line between these and the brightness, the simple sincerity, and healthy, rejuvenating strength of genuine mysticism, which takes the most precious gems from philosophy's treasure chest and displays them in the beauty of its own setting. Mysticism is in complete accord with the result, with the sum of philosophy. In fact, mysticism is precisely the sum and the soul of philosophy, in the form of that rapturous, passionate outpouring of love.... We are concerned with an understanding of this serious mysticism, and its meaning could be stated in three words... godlessness... freedom from the world... blessedness of soul."

“From the midst of the flat plain of human reason, there arises the terrible, fire-spewing mountain of genius.”

“In mysticism, everything is thrown at us directly, without discursiveness and ratiocination, as if it were a matter of course, and we are challenged to follow an unrestrainable will to love, arising out of a tremendously agitated, indiscriminate feeling. … Mystics will—rather than know—their thoughts. … Mysticism witnesses nothing but love; mysticism is nothing but love. … Art shows how it loves, philosophy what it loves; mysticism knows only that it loves.”

“Socrates and Christ speak to us everlastingly of mankind. … It belongs to the great, to the greatest men to say how things are with mankind, how they stand in its innerness and which way it is going; it belongs to Socrates and Christ. These absolutely extraordinary, eternally alive people penetrate to the groundless depth of human nature and understand the speech of ordinary people, of those who are scarcely alive from one day to the next.”

“And so, from this day forth, we want all the more to let our thoughts revolve around and hover over Socrates and Christ at all times, openly taking pride that they are more alive for us than all those living today and that we listen to and love them as we do none of the living.”

“Men are forever doing two things at the same time: acting egoistically and talking moralistically.”

“Christ … made the blood of the specialists and leading spirits, the representatives of the people boil with his battle-cry: "I", "I", "I"! and provoked the enraged counterblast: We, We, We!”
