“The drive of his own nature to keep developing prevents him from believing that anything is final and complete, yet everything he encounters behaves as though it were final and complete. He suspects that the given order of things is not as solid as it pretends to be; no thing, no self, no form, no principle, is safe, everything is undergoing an invisible but ceaseless transformation, the unsettled holds more of the future than the settled, and the present is nothing but a hypothesis that has not yet been surmounted. What better can he do than hold himself apart from the world, in the good sense exemplified by the scientist's guarded attitude toward facts that might be tempting him to premature conclusions? Hence he hesitates in trying to make something of himself; a character, a profession, a fixed mode of being, are for him concepts that already shadow forth the outlines of the skeleton, which is all that will be left of him in the end.”
