This is an important distinction, because most of the modern philosophies that deny that we can know reality, and ultimately truth, make the mistake of constructing epistemological systems to explain how we know reality without first acknowledging the fact that we do know reality. After they begin within the mind and find they can't construct a bridge to reality, they then declare that we can't know reality. It is like drawing a faulty road map before looking at the roads, then declaring that we can't know how to get from Chicago to New York!
