The vainglory of wishing to understand is dangerous, immoral and, above all, old-fashioned. The modern way – perhaps the final way - is to say: Go forward, without knowing why, as quickly as possible, towards an unknown goal! To act and think are opposites which identify one only in the Absolute. To accomplish all one's movements – of the head, the arms, the legs – without ever quite attaining the status of a puppet, but with a certainty that gives one a feeling of rightness: that is what is nowadays held up as the ideal. Be citizens of Universal activity! Forget to be conscious of ourselves! The blind horse gallops without hesitation, not knowing where it is going, not caring where it has been: so let up put out our eyes!
