Innatism and the Stoa

Our disagreements concern points of some importance. There is the question whether the soul in itself is blank like a writing tablet on which nothing has as yet been written – a tabula rasa – as Aristotle and the author of the Essay maintain, and whether everything which is inscribed there comes solely from the senses and experience; or whether the soul inherently contains the sources of various notions and doctrines which external objects merely rouse up on suitable occasions, as I believe and as do Plato and even the Schoolmen, and those who understand in this sense the passage in Saint Paul where he says that God's law is written in our hearts (Rom. 2:15). The Stoics call these sources Prolepses, that is fundamental assumptions or things taken for granted in advance.
