I read mystics with real pleasure. Mystics: men who claim to see what I do not see, who argue with what I cannot prove. And pleasure, of course, to know myself eliminating to the last trace the ignorant presumption that characterizes the man of this century responsible for molding me. I am happy to see that there may be others with faculties that I do not possess, that I do not represent the human model in the fullness of capabilities. To me, reading them is always a lesson in humility.
