"For if Irritability subsists in parts separate from the body, and not subject to the command of the soul, if it resides every where in the muscular fibres, and is independent of the nerves, which are the <EM>satellites</EM> of the soul, it is evident, that it has nothing in common with the soul, and it is absolutely different from it; in a word, that neither Irritability depends upon the soul, nor is the soul what we call Irritability in the body."
