How came the bodies of animals to be contrived with so much art, and for what ends were their several parts? Was the eye contrived without skill in Opticks, and the ear without knowledge of sounds?...and these things being rightly dispatchโd, does it not appear from phรฆnomena that there is a Being incorporeal, living, intelligent...?
Isaac NewtonThe main Business of Natural Philosophy is to argue from Phรฆnomena without feigning Hypotheses, and to deduce Causes from Effects till we come to the very first Cause, which certainly is not mechanical; and not only to unfold the Mechanism of the World, but chiefly to resolve these, and to such like Questions.
Isaac Newton
