Strona 143 - It is inconceivable, that inanimate brute matter should, without the mediation of something else, which is not material, operate upon, and affect other matter without mutual contact; as it must do, if gravitation, in the sense of Epicurus, be essential and inherent in it.
Strona 143 - That gravity should be innate, inherent, and essential to matter, so that one body may act upon another at a distance through a vacuum, without the mediation of anything else, by and through which their action and force may be conveyed from one to another, is to me so great an. absurdity, that I believe no man who has in philosophical! matters a competent faculty of thinking, can ever fall into it.

Strona 76 - We learn from anatomy, that the immediate object of power in voluntary motion, is not the member itself which is moved, but certain muscles, and nerves, and animal spirits, and, perhaps, something still more minute and more unknown...
Strona 65 - Science is built up with facts, as a house is with stones. But a collection of facts is no more a science than a heap of stones is a house.
