Abstract

So far as his critical employment of the concept is concerned, the thing in itself is not a second object. The thing in itself is given in its appearances; it is the object which appears. In other words, the object is taken in a twofold sense. There is no contradiction, Kant maintained, in supposing that one and the same will is, as an appearance, determined by the laws of nature and yet, as a thing in itself, is free. He never meant to hold that the self of the theoretical reason and the self of the practical reason are two separate and distinct entities. It is one and the same object considered from two perspectives. In this sense the thing in itself is purely a limiting concept. So far as the critical method is concerned, objects are always considered from a particular and limited perspective, e.g. science, morality, art, et cetera. This is the central meaning of his theory of appearances. In this employment of the concept it is completely meaningless to speak of the thing in itself as a cause of appearances. The critical distinction between appearances and things in themselves is not intended to be a distinction between subjective sense data and public objects, but between public objects as given according to two or more modes. This involves no extension of the category of causality beyond appearances. Moreover, it is not open to the charge that an unknown object is given the attribute of existence. The thing in itself is known as an appearance. By definition that is the only way that it could be known. To say that we know only appearances and not things in themselves is to state an obvious tautology, namely that objects are known only as they are known.
