Rh On the other hand those properties which are possessed by the living, and not by the dead arm, do not exist in a changed form in the latter: they simply do not exist there at all. By a causal necessity their existence depends on their having that relation to the other parts of the body which we express by saying that they form part of it. Yet, most certainly, if they ever did not form part of the body, they would be exactly what they are when they do. That they differ intrinsically from the properties of the dead arm and that they form part of the body are propositions not analytically related to one another. There is no contradiction in supposing them to retain such intrinsic differences and yet not to form part of the body.

But (b) when we are told that a living arm has no meaning or significance apart from the body to which it belongs, a different fallacy is also suggested. ‘To have meaning or significance’ is commonly used in the sense of ‘to have importance’; and this again means ‘to have value either as a means or as an end.’ Now it is quite possible that even a living arm, apart from its body, would have no intrinsic value whatever; although the whole of which it is a part has great intrinsic value owing to its presence. Thus we may easily come to say that, as a part of the body, it has great value, whereas by itself it would have none; and thus that its whole ‘meaning’ lies in its relation to the body. But in fact the value in question obviously does not belong to it at all. To have value merely as a part is equivalent to having no value at all, but merely being a part of that which has it. Owing, however, to neglect of this distinction, the assertion that a part has value, as a part, which it would not otherwise have, easily leads to the assumption that it is also different, as a part, from what it would otherwise be; for it is, in fact, true that two things which have a different value must also differ in other respects. Hence the assumption that one and the same thing, because it is a part of a more valuable whole at one time than at another, therefore has more intrinsic value at one time than at another, has encouraged the self-contradictory belief that one and the same thing may be two different things, and that only in one of its forms is it truly what it is.

For these reasons, I shall, where it seems convenient, take
