Nihil est in intellectu quod non prius fuerit in sensu
Nihil est in intellectu quod non prius fuerit in sensu
(Lat.) Nothing is in the intellect which was not first in sense. All the materials, or content, of higher, intellectual cognition are derived from the activity of lower, sense cognition. A principle subscribed to by Aristotle, St. Thomas and Locke; opposed by Plato, St. Augustine and Leibniz (who qualified the proposition by addingnisi intellectus ipse, i.e. except for what is already present as part of the innate nature of the intellect, thus making it possible for Kant to suggest that certain forms of sensibility and reason are prior to sense experience). — V.J.B.
