A: assent (character and ext. cause) interconnectedness of all things - pneuma / tonos - mixture: even one drop of win in the ocean will permeate the entire ocean? - 4 elements accepted from Aristotle, but the qualities are differently mapped - 4 causes rejected: instead we get just “the active and passive principles” and the elements note: active principle is material (bc it is a cause) and active principle = soul = pneuma = Zeus = reason “What is science is not Roman, what is Roman is not science” Cicer0 – “Aristotle thought that even the people who rave from the effects of sickness and are called ‘hypochondriacs’ have within their souls some power of foresight and of prophecy.
