Postulate Quotes - page 3
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.

However difficult those simple beginnings may be to accept, they are a whole lot easier to accept than complicated beginnings. Complicated things come into the universe late, as a consequence of slow, gradual, incremental steps. God, if he exists, would have to be a very, very, very complicated thing indeed. So to postulate a God as the beginning of the universe, as the answer to the riddle of the first cause, is to shoot yourself in the conceptual foot because you are immediately postulating something far far more complicated than that which you are trying to explain.

A law explains a set of observations; a theory explains a set of laws. The quintessential illustration of this jump in level is the way in which Newton's theory of mechanics explained Kepler's law of planetary motion. Basically, a law applies to observed phenomena in one domain (e.g., planetary bodies and their movements), while a theory is intended to unify phenomena in many domains. Thus, Newton's theory of mechanics explained not only Kepler's laws, but also Galileo's findings about the motion of balls rolling down an inclined plane, as well as the pattern of oceanic tides. Unlike laws, theories often postulate unobservable objects as part of their explanatory mechanism. So, for instance, Freud's theory of mind relies upon the unobservable ego, superego, and id, and in modern physics we have theories of elementary particles that postulate various types of quarks, all of which have yet to be observed.
