Of the Interior Beginnings of Voluntary Motions; Commonly Called the Passions; and the Speeches by Which They Are Expressed
There be in animals, two sorts of “motions” peculiar to them: one called “vital”; begun in generation, and continued without interruption through their whole life; such as are the “course” of the “blood,” the “pulse,” the “breathing,” the “concoction, nutrition, excretion,” etc. , to which motions there needs no help of imagination: the other is “animal motion,” otherwise called “voluntary motion”; as to “go,” to “speak,” to “move” any of our limbs, in such manner as is first fancied in our minds. That sense is motion in the organs and interior parts of man’s body, caused by the action of the things we see, hear, etc.
