It may, indeed, be rejoined that effects are deliberately ignored by this school; which teaches that courses recognized by moral intuition as right, must be pursued without regard to consequences. But on inquiry it turns out that the consequences to be disregarded are particular consequences, and not general consequences. When, for example, it is said that property lost by another ought to be restored, irrespective of evil to the finder, who possibly may, by restoring it, lose that which would have preserved him from starvation, it is meant that in pursuance of the principle, the immediate and special consequences must be disregarded, not the diffused and remote consequences. By which we are shown that though the theory forbids overt recognition of causation, there is an unavowed recognition of it. And this implies the trait to which I am drawing attention. The conception of natural causation is so imperfectly developed that there is only an indistinct consciousness that throughout the whole of human conduct necessary relations of causes and effects prevail, and that from them are ultimately derived all moral rules, however much these may be proximately derived from moral intuitions. § 21. Strange to say, even the utilitarian school, which, at first sight, appears to be distinguished from the rest by recognizing natural causation, is, if not so far from complete recognition of it, yet very far. Conduct, according to its theory, is to be estimated by observation of results. When, in sufficiently numerous cases, it has been found that behavior of this kind works evil while behavior of that kind works good, these kinds of behavior are to be judged as wrong and right respectively. Now though it seems that the origin of moral rules in natural causes, is thus asserted by implication, it is but partially asserted. The implication is simply that we are to ascertain by induction that such and such mischiefs or benefits _do_ go along with such and such acts; and are then to infer that the like relations will hold in future. But acceptance of these generalizations and the inferences from them does not amount to recognition of causation in the full sense of the word. So long as only _some_ relation between cause and effect in conduct is recognized, and not _the_ relation, a completely scientific form of knowledge has not been reached. At present, utilitarians pay no attention to this distinction. Even when it is pointed out they disregard the fact that empirical utilitarianism is but a transitional form to be passed through on the way to rational utilitarianism. In a letter to Mr. Mill, written some sixteen years ago, repudiating the title anti-utilitarian, which he had applied to me (a letter subsequently published in Mr. Bain's work on _Mental and Moral Science_), I endeavored to make clear the difference above indicated; and I must here quote certain passages from that letter.
