reality which the rules of caste possess for each of our three men is different, in accord with the differences in their characteristic purposes. For the historian, they are real as a system of ideas which have influenced and do influence the conduct of the society of which he is writing the history, in such a way that without understanding them he cannot get a clear insight into the social structure of Hinduism. To the native Christian, they are real as a standing source of difficulty and a standing temptation to be false to his highest ideals of conduct. To the Shivaite, they are real as the divinely appointed means to bodily and spiritual purification from the evil that is in the world. § 2. So far, then, it might seem that “reality” is a purely relative term, and that our previous choice of ultimate freedom from contradiction as our standard of reality was an arbitrary one, due to the mere accident that _our_ special purpose in sitting down to study Metaphysics is to think consistently. Of course, it might be said, whatever game you choose to play at, the rules of that particular game must be your supreme reality, so long as you are engaged in it. But it depends on your own choice what game you will play and how long you will keep at it. There is no game at which we all, irrespective of personal choice, have to play, and there is therefore no such thing as an ultimate reality which we must all recognise as such; there are only the special realities which correspond to our special individual purposes. You have no right to set up the particular rules of the game of scientific thought as a reality unconditionally demanding recognition from those who do not choose to play that particular game.[32]
