Abstract

These two powers or capacities cannot exchange their functions. The understanding can intuit nothing, the senses can think nothing. Only through their union can knowledge arise. But that is no reason for confounding the contribution of either with that of the other; rather is it a strong reason for carefully separating and distinguishing the one from the other. The passages are so well known because Kant laid such massive importance on them. His claims about the strict distinction between these two “sources,” even as he emphasized their necessarily intertwined, even inseparable role in knowledge, was the basis of his critique of the entire prior philosophical tradition, elements of which, he famously claimed, either “sensualized all concepts of the understanding” or “intellectualized” appearances.[i].
