 VI] only consider what results it is possible for us to obtain, but also which, among equally possible results, will have the greatest value. And upon this second enquiry the comparative valuation of known goods has a no less important bearing than upon the investigation of the Absolute Good.

112. The method which must be employed in order to decide the question ‘What things have intrinsic value, and in what degrees?’ has already been explained in Chap. III. (§§ 55, 57). In order to arrive at a correct decision on the first part of this question, it is necessary to consider what things are such that, if they existed by themselves, in absolute isolation, we should yet judge their existence to be good; and, in order to decide upon the relative degrees of value of different things, we must similarly consider what comparative value seems to attach to the isolated existence of each. By employing this method, we shall guard against two errors, which seem to have been the chief causes which have vitiated previous conclusions on the subject. The first of these is (1) that which consists in supposing that what seems absolutely necessary here and now, for the existence of anything good—what we cannot do without—is therefore good in itself. If we isolate such things, which are mere means to good, and suppose a world in which they alone, and nothing but they, existed, their intrinsic worthlessness becomes apparent. And, secondly, there is the more subtle error (2) which consists in neglecting the principle of organic unities. This error is committed, when it is supposed, that, if one part of a whole has no intrinsic value, the value of the whole must reside entirely in the other parts. It has, in this way, been commonly supposed, that, if all valuable wholes could be seen to have one and only one common property, the wholes must be valuable solely because they possess this property; and the illusion is greatly strengthened, if the common property in question seems, considered by itself, to have more value than the other parts of such wholes, considered by themselves. But, if we consider the property in question, in isolation, and then compare it with the whole, of which it forms a part, it may become easily apparent that, existing by itself, the property in question has not nearly
