The title 'Human Nature,' given to Butler's chief Ethical exposition, indicates that he does not take an a priori view of the foundations of Ethics, like Cudworth and Clarke, but makes them repose on the constitution of the human mind.
In Sermon first, he lays out the different parts of our Emotional and Active nature, including Benevolence, Self-love, Conscience. The recognition of these three as distinct, and mutually irresolvable, is the Psychological basis of his Ethics.[20]
The existence of pure or disinterested Benevolence is proved by such facts, as Friendship, Compassion, Parental and Filial affections, Benevolent impulses to mankind generally. But although the object of benevolence is the public good, and of self-love private good, yet the two ultimately coincide. [This questionable assertion must trammel any proof that the author can give of our possessing purely disinterested impulses.]
In a long note, he impugns the theory of Hobbes that Benevolent affection and its pleasures are merely a form of the love of Power. He maintains, and with reason, that the love of power manifests its consequences quite as much in cruelty as in benevolence.
The second argument, to show that Benevolence is a fact of our constitution, involves the greatest peculiarity of Butler's Psychology, although he was not the first to announce it. The scheme of the human feelings comprehends, in addition to Benevolence and Self-Love, a number of passions and affections tending to the same ends as these (some to the good of our fellows, others to our own good); while in following them we are not conscious of seeking those ends, but some different ends. Such are our various Appetites and Passions. Thus, hunger promotes our private well-being, but in obeying its dictates we are not thinking of that object, but of the procuring of food. Curiosity promotes both public and private good, but its direct and immediate object is knowledge.
This refined distinction appears first in Aquinas; there is in it a palpable confusion of ideas. If we regard the final impulse of hunger, it is not toward the food, but towards the appeasing of a pain and the gaining of a pleasure, which are certainly identical with self, being the definition of self in the last resort. We associate the food with the gratification of these demands, and hence food becomes an end to us—one of the associated or intermediate ends. So the desire of knowledge is the desire of the pleasure, or of the relief from pain, accruing from knowledge; while, as in the case of food, knowledge is to a great degree only an instrument, and therefore an intermediate and associated end. So the desire of esteem is the desire of a pleasure, or else of the instrument of pleasure.
In short, Butler tries, without effect, to evade the general principles of the will—our being moved exclusively by pleasure and pain. Abundant reference has been already made to the circumstances that modify in appearance, or in reality, the operation of this principle. The distinction between self-love and the particular appetites, passions, and affections, is mainly the distinction between a great aggregate of the reason (the total interests of our being) and the separate items that make it up.
The distinction is intended to prepare the way for the setting forth of Conscience,[21] which is called a 'principle of reflection in men, whereby they distinguish between, approve and disapprove, their own actions.' This principle has for its result the good of society; still, in following it, we are not conscious of aiming at the good of society. A father has an affection for his children; this is one thing. He has also a principle of reflection, that urges him with added force and with more steady persistency than any affection, which principle must therefore be different from mere affection.
Butler's analysis of the human feelings is thus: I.—Benevolence and Self-love. II.—The particular Appetites, Passions, and Affections, operating in the same direction as Benevolence and Self-love, but without intending it. III.—Conscience, of which the same is to be said.
His reply to the objection,—against our being made for Benevolence,—founded on our mischievous propensities, is, that in the same way there are tendencies mischievous to ourselves, and yet no one denies us the possession of self-love. He remarks farther that these evil tendencies are the abuse of such as are right; ungovernable passion, reckless pursuit of our own good, and not pure malevolence, are the causes of injustice and the other vices.
