Every truth is the reference of a judgment to something outside of it, and the term intrinsic truth is a contradiction.

§ 31. Empirical Truth.

When we say, "A judgment has material truth" we mean on the whole, that its conceptions are connected, separated, limited, according to the requirements of the intuitive representations through which it is inferred. To attain knowledge of this, is the direct function of the ''
