198): as it was said above (p. 183), if the axe had its form in the determination of substance, this form would be the soul of the axe. The illustration of the wax has reference to nothing but the fact that only the form comes to the soul; and has nothing to do with the form being external to the wax and remaining so, or with the soul having, like wax, no independent form. The soul is by no means said to be passive wax and to receive its determinations from without; but Aristotle, as we shall soon see (p. 194), really says that the spirit repels matter from itself, and maintains itself against it, having relation only to form. In sense-perception the soul is certainly passive, but the manner in which it receives is not like that of the wax, being just as truly activity of the soul; for after the perceptive faculty has received the impression, it abrogates the passivity, and remains thenceforth free from it (_supra_, p. 187). The soul therefore changes the form of the external body into its own, and is identical with an abstract quality such as this, for the sole reason that it itself is this universal form. This description of sense-perception Aristotle explains more fully in what follows (De Anima, III. 2), and expatiates upon this unity and its contrasts, in the course of which explanation there appear many clear and far-reaching glimpses into the Nature of consciousness. “The bodily organ of each sense-perception receives the object perceived without matter. Hence, when the object of sense is removed, the perceptions and the images which represent them remain in the organs. In the act of sense-perception the object perceived is no doubt identical with the subject that perceives, but they do not exist[97] as the same; for instance, sound and the hearing are the same when in active exercise, but that which has hearing does not always hear, and that which has sound is not always sounding. When that which is the potentiality of hearing comes into exercise, and likewise that which is the potentiality of sound, hearing and sound, being in full activity, coincide,” they do not remain separate energies. “If then movement and action, as well as passivity, have a place in the object on which activity is exercised (ἐν τῷ ποιουμένῳ), it follows necessarily that the energy of hearing and sound is contained in that which potentially is hearing, for the energy of the active and moving is in the passive. As therefore activity and passivity are manifested in the subject which receives the effect, and not in the object which produces it (ποιοῦντι), the energy both of the object and of the faculty of sense-perception is in the faculty itself. For hearing and sounding there are two words, for seeing only one; seeing is the activity of the person who sees, but the activity of the colour is without name. Since the energy of that which is perceived and that which perceives is one energy, and the aspect they present is alone different, the
