    When a person little accustomed to metaphysical specula- tions is told, that, in case of volition, there are certain invisi- ble fluids propagated from the mind to the organ which is moved ; and that, in the case of perception, the existence and qualities of the external object are made known by means of species or phantasms, or images, which are present to the mind in the sensorium; he is apt to conclude, that the inter- course between mind and matter is left more mysterious than he had supposed; and that, although these expressions may not convey to him any very distinct meaning, their import is perfectly understood by philosophers.
