Or as they say in Latin (A Scholastic maxim derived from Aristotle) "Nihil est in intellectu quod non prius in sensu".
This is also an empiricist maxim that in its most basic form states that "knowledge arises from evidence gathered via sense experience" and that the mind is a blank slate.
This is often contrasted with rationalism which argues that certain concepts and knowledge are innate and "gained a priori, independently of experience".
Rationalist or Empiricist? Why?
