30Classification of the Sci. familiar with the fundamentals of dynamics that if physical forces obey the law of the conservation of energy, then a volition cannot be a force. For a volition is motived by every circumstance that is seen to have an influence upon the desired result, while the result of the action of a conservative force depends on two factors, the initial positions and the initial states of motion, only the former of which influences the force, the latter being left to produce such effect as it may. The force cannot be influenced by the velocities without thereby violating the law of the conservation of energy. So vague are the notions that prevail on this subject, that many persons will exclaim, "But surely all events in the physical world are governed by force!" Let us admit, for the sake of argument, what has perhaps been rendered probably, and perhaps not, but has certainly not been rendered nearly certain, that the laws of dynamics, including the law of the conservation of energy, together with certain fixed laws of physics, are never violated in any sensible measure; but that whatever they prescribe is sensibly true: | 30 |
