—that a world, from which material qualities were wholly banished, would be a world which lacked many, if not all, of those things, which we know most certainly to be great goods. That it might nevertheless be a far better world than one which retained these goods, I have already admitted (§ 111 (1)). But in order to shew that any such world would be thus better, it would be necessary to shew that the retention of these things, though good in themselves, impaired, in a more than equal degree, the value of some whole, to which they might belong; and the task of shewing this has certainly never been attempted. Until it be performed, we are entitled to assert that material qualities are a necessary constituent of the Ideal; that, though something utterly unknown might be better than any world containing them or any other good we know, yet we have no reason to suppose that anything whatever would be better than a state of things in which they were included. To deny and exclude matter, is to deny and exclude the best we know. That a thing may retain its value, while losing some of its qualities, is utterly untrue. All that is true is that the changed thing may have more value than, or as much value as, that of which the qualities have been lost. What I contend is that nothing, which we know to be good, and which contains no material qualities, has such great value that we can declare it, by itself, to be superior to the whole which would be formed by the addition to it of an appreciation of material qualities. That a purely spiritual good may be the best of single things, I am not much concerned to dispute, although, in what has been said with regard to the nature of personal affection, I have given reasons for doubting it. But that by adding to it some appreciation of material qualities, which, though perhaps inferior by itself, is certainly a great positive good, we should obtain a greater sum of value, which no corresponding decrease in the value of the whole, as a whole, could counterbalance—this, I maintain, we have certainly no reason to doubt.
124. In order to complete this discussion of the main principles involved in the determination of intrinsic value, the chief remaining topics, necessary to be treated, appear to be two. The first of these is the nature of great intrinsic evils,
