37 Hume on this, as on most other points, was emphatically opposed to the school of Hobbes, and even declared that no one could honestly and in good faith deny the reality of an unselfish element in man. Following in the steps of Butler, he explained it in the following passage:—“Hunger and thirst have eating and drinking for their end, and from the gratification of these primary appetites arises a pleasure which may become the object of another species of desire or inclination that is secondary and interested. In the same manner there are mental passions by which we are impelled immediately to seek particular objects, such as fame or power or vengeance, without any regard to interest, and when these objects are attained a pleasing enjoyment ensues.... Now where is the difficulty of conceiving that this may likewise be the case with benevolence and friendship, and that from the original frame of our temper we may feel a desire of another’s happiness or good, which by means of that affection becomes our own good, and is afterwards pursued, from the combined motives of benevolence and self-enjoyment?”—Hume’s _Enquiry concerning Morals_, Appendix II. Compare Butler, “If there be any appetite or any inward principle besides self-love, why may there not be an affection towards the good of our fellow-creatures, and delight from that affection’s being gratified and uneasiness from things going contrary to it?”—_Sermon on Compassion._ 38 “By sympathetic sensibility is to be understood the propensity that a man has to derive pleasure from the happiness, and pain from the unhappiness, of other sensitive beings.”—Bentham’s _Principles of Morals and Legislation_, ch. vi. “The sense of sympathy is universal. Perhaps there never existed a human being who had reached full age without the experience of pleasure at another’s pleasure, of uneasiness at another’s pain.... Community of interests, similarity of opinion, are sources from whence it springs.”—_Deontology_, vol. i. pp. 169-170. 39 “The idea of the pain of another is naturally painful. The idea of the pleasure of another is naturally pleasurable.... In this, the unselfish part of our nature, lies a foundation, even independently of inculcation from without, for the generation of moral feelings”—Mill’s _Dissertations_, vol. i. p. 137. See, too, Bain’s _Emotions and the Will_, pp. 289, 313; and especially Austin’s _Lectures on Jurisprudence_. The first volume of this brilliant work contains, I think without exception, the best modern statement of the utilitarian theory in its most plausible form—a statement equally remarkable for its ability, its candour, and its uniform courtesy to opponents.
