V. The inventive genius of modern Ethic is exhausted with these thinkers. Their successors have reproduced the old situations, one after the other. Some, while accepting the Kantian morality, wished to temper and correct its exaggerations, which was not possible, save by a more profound speculative vision of the relation between pleasure and good, the useful and the moral; whereas they believed that they could attain to it by _also_ taking account of pleasure and of happiness, and by conceiving a doctrine of happiness or eudæmonology side by side with Ethic, but subordinate to it (in Italy: Galluppi and Rosmini). Schiller had already recognized in Kant's time the unilaterality of Kant, and had made it the object of criticism and of epigram, which, however, does not mean that he had truly and properly corrected its errors. Others occupied themselves in various ways with the enumeration and juxtaposition of the principles: thus, for instance, Schopenhauer makes compassion arise beside egoism, which then divides into benevolence and justice; and Herbart, although he excludes the useful, because, according to him, "it refers to a point external to itself,"[20] enumerates five practical ideas that are not all truly moral. The affinity both of Herbart and of Schopenhauer, with Shaftesbury, Hutcheson and English and Scottish psychologism, is clear. The study of the practical ideas of Herbart is not without interest as an unconscious affirmation of the necessity of the economic principle. The first of these, indeed, _internal freedom,_ consists in being able to achieve with our own strength the model that we propose to ourselves, and is liberty, but not yet moral liberty. "To be able to decide _according to motives_" (says Herbart on one occasion) "is already a sign of psychical health: to decide _according to the best motives_ is the condition of morality."[21] The second of the practical ideas, that of _perfection,_ is concerned precisely with the strength of the will, taken in itself, and resembles a combination of the Hellenic virtues of fortitude and temperance. Here willing is considered in itself, independently of its objects, and in this consideration there is no other difference, save their strength, between the various Willings: the greater this is, the more it is admired; weakness displeases and strength pleases the practical judgment, and this even when it is unjust, iniquitous and wicked, and notwithstanding such vices.[22] Lotze, following Herbart, determines as requisites of actions, that they must be possible, energetic, conscientious on the one hand, and on the other, consequent, habitual, individual, stating that these two series of predicates apply equally to moral and immoral actions.[23]--He does not think it worth while to take count of the English utilitarians and post-Kantian intuitionists, or of their French, Italian, and German imitators; because, just as the
