Note (return) — Chapter XI
Reading edition
2. It may be expected that a system of physics raised on optimistic principles will be mathematical rather than experimental. "Intended to embody conceptions of proportion and harmony, it will have recourse to that department of science which deals with the proportions in space and number. Such applications of mathematical truths, not being raised on ascertained facts, can only accidentally represent the real laws of the physical system; they will, however, vivify the student's apprehension of harmony in the same manner as a happy parable, though not founded in real history, will enliven his perceptions of moral truth." 656
