“Western philosophy and science have for the most part been committed to the Simplicity Theory of Truth: the simplest theory that accounts for the data is the true theory. (Theories are simplest which postulate the fewest entities, require the fewest hypotheses, generate predictions by the fewest calculations, etc.) ...If someone believes that the world is made for him to have dominion over and he is made to exploit it, he must believe that he and the world are so made that he can, at least in principle, achieve and maintain dominion over everything. But you can’t put things to use if you don’t know how they work. So he must believe that he can, at least in principle, understand everything. If the world exists for man, it must be usably intelligible, which means it must be simple enough for him to understand. A usable universe is an intelligible universe is a simple universe. ...And so it goes with the philosophy and the science of The Arrogant Eye.”
