"First, in so far as our external senses are all parts of the body, sense-perception, strictly speaking, is merely passive, even though our application of the senses to objects involves action, viz. local motion; sense-perception occurs in the same way in which wax takes on an impression from a seal."
— Descartes, René (1596-1650)
(Rule 12, p. 40)
