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 the liberty to use the term ‘organic’ with a special sense. I shall use it to denote the fact that a whole has an intrinsic value different in amount from the sum of the values of its parts. I shall use it to denote this and only this. The term will not imply any causal relation whatever between the parts of the whole in question. And it will not imply either, that the parts are inconceivable except as parts of that whole, or that, when they form parts of such a whole, they have a value different from that which they would have if they did not. Understood in this special and perfectly definite sense the relation of an organic whole to its parts is one of the most important which Ethics has to recognise. A chief part of that science should be occupied in comparing the relative values of various goods; and the grossest errors will be committed in such comparison if it be assumed that wherever two things form a whole, the value of that whole is merely the sum of the values of those two things. With this question of ‘organic wholes,’ then, we complete the enumeration of the kind of problems, with which it is the business of Ethics to deal.
