"Aristotle taught, that all the objects of our thought enter at first by the senses; and, since the sense cannot receive external material objects themselves, it receives their species; that is, their images or forms, without the matter; as wax receives the form of the seal without any of the matter of it."
— Reid, Thomas (1710-1796)
