on the utilitarian side a position corresponding in importance to the doctrine of innate moral faculties as distinguished from innate moral ideas on the intuitive side, was not absolutely unknown to the ancients, though they never perceived either the extent to which it may be carried or the important consequences that might be deduced from it. Some traces of it may be found in Aristotle,40 and some of the Epicureans applied it to friendship, maintaining that, although we first of all love our friend on account of the pleasure he can give us, we come soon to love him for his own sake, and apart from all considerations of utility.41 Among moderns Locke has the merit of having devised the phrase, “association of ideas;”42 but he applied it only to some cases of apparently eccentric sympathies or antipathies. Hutcheson, however, closely anticipated both the doctrine of Hartley and the favourite illustration of the school; observing that we desire some things as themselves pleasurable and others only as means to obtain pleasurable things, and that these latter, which he terms “secondary desires,” may become as powerful as the former. “Thus, as soon as we come to apprehend the use of wealth or power to gratify any of our original desires we must also desire them. Hence arises the universality of these desires of wealth and power, since they are the means of gratifying all our desires.”43 The same principles were carried much farther by a clergyman named Gay in a short dissertation which is now almost forgotten, but to which Hartley ascribed the first suggestion of his theory,44 and in which indeed the most valuable part of it is clearly laid down. Differing altogether from Hutcheson as to the existence of any innate moral sense or principle of benevolence in man, Gay admitted that the arguments of Hutcheson to prove that the adult man possesses a moral sense were irresistible, and he attempted to reconcile this fact with the teaching of Locke by the doctrine of “secondary desires.” He remarks that in our reasonings we do not always fall back upon first principles or axioms, but sometimes start from propositions which though not self-evident we know to be capable of proof. In the same way in justifying our actions we do not always appeal to the tendency to produce happiness which is their one ultimate justification, but content ourselves by showing that they produce some of the known “means to happiness.” These “means to happiness” being continually appealed to as justifying motives come insensibly to be regarded as ends, possessing an intrinsic value irrespective of their tendency; and in this manner it is that we love and admire virtue even when unconnected with our interests.45
The great work of Hartley expanding and elaborating these views was published in 1747. It was encumbered by much physiological speculation into which it is needless for us now to enter, about the manner in which emotions act upon the nerves, and although accepted enthusiastically by Priestley and Belsham, and in some degree by Tucker, I do not think that its purely ethical speculations had much influence until they were adopted by some leading utilitarians in the present century.46 Whatever may be thought of the truth, it is impossible to withhold some admiration from the intellectual grandeur of a system which starting from a conception of human nature as low and as base as that of Mandeville or Hobbes professes without the introduction of a single new or nobler element, by a strange process of philosophic alchemy, to evolve out of this original selfishness the most heroic and most sensitive virtue. The manner in which this achievement is effected is commonly illustrated by the passion of avarice. Money in itself possesses absolutely nothing that is admirable or pleasurable, but being the means of procuring us many of the objects of our desire, it becomes associated in our minds with the idea of pleasure; it is therefore itself loved; and it is possible for the love of money so completely to eclipse or supersede the love of all those things which money procures, that the miser will forego them all, rather than part with a fraction of his gold.47
The same phenomenon may be traced, it is said, in a multitude of other forms.48 Thus we seek power, because it gives us the means of gratifying many desires. It becomes associated with those desires, and is, at last, itself passionately loved. Praise indicates the affection of the eulogist, and marks us out for the affection of others. Valued at first as a means, it is soon desired as an end, and to such a pitch can our enthusiasm rise, that we may sacrifice all earthly things for posthumous praise which can never reach our ear. And the force of association may extend even farther. We love praise, because it procures us certain advantages. We then love it more than these advantages. We proceed by the same process to transfer our affections to those things which naturally or generally procure praise. We at last love what is praiseworthy more than praise, and will endure perpetual obloquy rather than abandon it.49 To this process, it is said, all our moral sentiments must be ascribed. Man has no natural benevolent feelings. He is at first governed solely by his interest, but the infant learns to associate its pleasures with the idea of its mother, the boy with the idea of his family, the man with those of his class, his church, his country, and at last of all mankind, and in each case an independent affection is at length formed.50 The sight of suffering in others awakens in the child a painful recollection of his own sufferings, which parents, by appealing to the infant imagination, still further strengthen, and besides, “when several children are educated together, the pains, the denials of pleasure, and the sorrows which affect one gradually extend in some degree to all;” and thus the suffering of others becomes associated with the idea of our own, and the feeling of compassion is engendered.51 Benevolence and justice are associated in our minds with the esteem of our fellow-men, with reciprocity of favours, and with the hope of future reward. They are loved at first for these, and finally for themselves, while opposite trains of association produce opposite feelings towards malevolence and injustice.52 And thus virtue, considered as a whole, becomes the supreme object of our affections. Of all our pleasures, more are derived from those acts which are called virtuous, than from any other source. The virtuous acts of others procure us countless advantages. Our own virtue obtains for us the esteem of men and return of favours. All the epithets of praise are appropriated to virtue, and all the epithets of blame to vice. Religion teaches us to connect hopes of infinite joy with the one, and fears of infinite suffering with the other. Virtue becomes therefore peculiarly associated with the idea of pleasurable things. It is soon loved, independently of and more than these; we feel a glow of pleasure in practising it, and an intense pain in violating it. Conscience, which is thus generated, becomes the ruling principle of our lives,53 and having learnt to sacrifice all earthly things rather than disobey it, we rise, by an association of ideas, into the loftiest region of heroism.54
The influence of this ingenious, though I think in some respect fanciful, theory depends less upon the number than upon the ability of its adherents. Though little known, I believe, beyond England, it has in England exercised a great fascination over exceedingly dissimilar minds,55 and it does undoubtedly evade some of the objections to the other forms of the inductive theory. Thus, when intuitive moralists contend that our moral judgments, being instantaneous and effected under the manifest impulse of an emotion of sympathy or repulsion, are as far as possible removed from that cold calculation of interests to which the utilitarian reduces them, it is answered, that the association of ideas is sufficient to engender a feeling which is the proximate cause of our decision.56 Alone, of all the moralists of this school, the disciple of Hartley recognises conscience as a real and important element of our nature,57 and maintains that it is possible to love virtue for itself as a form of happiness without any thought of ulterior consequences.58 The immense value this theory ascribes to education, gives it an unusual practical importance. When we are balancing between a crime and a virtue, our wills, it is said, are necessarily determined by the greater pleasure. If we find more pleasure in the vice than in the virtue, we inevitably gravitate to evil. If we find more pleasure in the virtue than in the vice, we are as irresistibly attracted towards good. But the strength of such motives may be immeasurably enhanced by an early association of ideas. If we have been accustomed from childhood to associate our ideas of praise and pleasure with virtue, we shall readily yield to virtuous motives; if with vice, to vicious ones. This readiness to yield to one or other set of motives, constitutes disposition, which is thus, according to these moralists, altogether an artificial thing, the product of education, and effected by association of ideas.59
It will be observed, however, that this theory, refined and imposing as it may appear, is still essentially a selfish one. Even when sacrificing all earthly objects through love of virtue, the good man is simply seeking his greatest enjoyment, indulging a kind of mental luxury which gives him more pleasure than what he foregoes, just as the miser finds more pleasure in accumulation than in any form of expenditure.60 There has been, indeed, one attempt
