“And in this, that philosophy begins in wonder [Plato, Theaetetus 155d], lies the, so to speak, non-bourgeois character of philosophy; for to feel astonishment and wonder is something non-bourgeois (if we can be allowed, for a moment, to use this all-too-easy terminology). For what does it mean to become bourgeois in the intellectual sense? More than anything else, it means that someone takes one's immediate surroundings (the world determined by the immediate purposes of life) so "tightly" and "densely," as if bearing an ultimate value, that the things of experience no longer become transparent. The greater, deeper, more real, and (at first) invisible world of essences is no longer even suspected to exist; the "wonder" is no longer there, it has no place to come from; the human being can no longer feel wonder. The commonplace mind, rendered deaf-mute, finds everything self-explanatory. But what really is self-explanatory? Is it self-explanatory, then, that we exist? Is it self-explanatory that there is such a thing as "seeing"? These are questions that someone who is locked into the daily world cannot ask; and that is so because such a person has not succeeded, as anyone whose senses (like a deaf person) are simply not functioning — has not managed even for once to forget the immediate needs of life, whereas the one who experiences wonder is one who, astounded by the deeper aspect of the world, cannot hear the immediate demands of life — if even for a moment, that moment when he gazes on the astounding vision of the world.”
