  Despite this commonality, Core Nativists are not one with Classical Rationalists.  Descartes took our innate Rational notion of the physical to be at the heart of the true physics.  Newton showed that this was wrong, and that we needed to go beyond our intuitive physics if we wanted to get a deeper understanding of the world.  Core Knowledge theorists reject the Classical assumption that our innate sense-making frameworks are necessarily true.  But true or not, what is innate provides a framework that we use to make sense of the world.  To this extent, the Core Knowledge program revitalizes this key Rationalist idea.  It remains an open question how we are to understand this notion of (deep) understanding.  This search goes back at least as far as Plato.  But our point here has not been to defend the revival of this Rationalist theme; only to note the commonality.
