A child might be overawed by a great city, but a civil engineer knows that he might demolish it and rebuild it himself. Husserl's philosophy has the same aim: to show us that, although we may have been thrust into this world without a 'by your leave,' we are mistaken to assume that it exists independently of us. It is true that reality exists apart from us; but what we mistake for the world is actually a world constituted by us, selected from an infinitely complex reality.
