However exalted the application of our concepts, and however far up from sensibility we may abstract them, still they will always be appended to image representations, whose proper function is to make these concepts, which are not otherwise derived from experience, serviceable for experiential use.

For a state is not a property (patrimonium), as may be the ground on which its people are settled. It is a society of human beings over whom no one but itself has the right to rule and to dispose. Like the trunk of a tree, it has its own roots, and to graft it on to another state is to do away with its existence as a moral person, and to make of it a thing.

First, as concerns the sources of metaphysical cognition, its very concept implies that they cannot be empirical. Its principles (including not only its basic propositions but also its basic concepts) must never be derived from experience. It must not be physical but metaphysical knowledge, i.e., knowledge lying beyond experience. It can therefore have for its basis neither external experience, which is the source of physics proper, nor internal, which is the basis of empirical psychology. It is therefore a priori cognition, coming from pure understanding and pure reason. p.11
