But (2) it may also be the case that our body as a whole has a value greater than the sum of values of its parts; and this may be what is meant when it is said that the parts are means to the whole. It is obvious that if we ask the question ‘Why _should_ the parts be such as they are?’ a proper answer may be ‘Because the whole they form has so much value.’ But it is equally obvious that the relation which we thus assert to exist between part and whole is quite different from that which we assert to exist between part and part when we say ‘This part exists, because that one could not exist without it.’ In the latter case we assert the two parts to be causally connected; but, in the former, part and whole cannot be causally connected, and the relation which we assert to exist between them may exist even though the parts are not causally connected either. All the parts of a picture do not have that relation of mutual causal dependence, which certain parts of the body have, and yet the existence of those which do not have it may be absolutely essential to the value of the whole. The two relations are quite distinct in kind, and we cannot infer the existence of the one from that of the other. It can, therefore, serve no useful purpose to include them both under the same name; and if we are to say that a whole is organic because its parts are (in this sense) ‘means’ to the whole, we must _not_ say that it is organic because its parts are causally dependent on one another. =22.= But finally (3) the sense which has been most prominent in recent uses of the term ‘organic whole’ is one whereby it asserts the parts of such a whole to have a property which the parts of no whole can possibly have. It is supposed that just as the whole would not be what it is but for the existence of the parts, so the parts would not be what they are but for the existence of the whole; and this is understood to mean not merely that any particular part could not exist unless the others existed too (which is the case where relation (1) exists between the parts), but actually that the part is no distinct object of thought--that the whole, of which it is a part, is in its turn a part of it. That this supposition is self-contradictory a very little reflection should be sufficient to shew. We may admit, indeed, that when a particular thing is a part of a whole, it does possess a predicate which it would not otherwise possess--namely that it is a part of that whole. But what cannot be admitted is that this predicate alters the nature or enters into the definition of the thing which has it. When we think of the part _itself_, we mean just _that which_ we assert, in this case, to _have_ the predicate that it is part of the whole; and the mere assertion that _it_ is a part of the whole involves that it should itself be distinct from that which we assert of it. Otherwise we contradict ourselves since we assert that, not _it_, but
