Section Ii.--_of the Invariability of Primary Moral Judgments_.

1. The following narrative is taken from Grote's History of Greece, c. 81.:

"It was a proud day for the Carthaginian general [Footnote 12] when he stood as master on the ground of Himera; enabled to fulfil the duty, and satisfy the exigencies, of revenge for his slain grandfather. Tragical indeed was the consummation of this long-cherished purpose.... All the male captives, 3,000 in number, were conveyed to the precise spot where Hamilkar had been slain, and there put to death with indignity, as an expiatory satisfaction to his lost honour. No man can read the account of this wholesale massacre without horror and repugnance. Yet we cannot doubt, that among all the acts of Hannibal's life, this was the one in which he most gloried; that it realized in the most complete and emphatic manner, his concurrent aspirations of filial sentiment, religious obligation, and honour as a patriot; [Footnote 13] that to show mercy would have been regarded as a mean dereliction of these esteemed impulses.... Doubtless, the feelings of Hannibal were cordially shared, and the plenitude of his revenge envied, by the army around him. So different, sometimes so totally contrary, is the tone and direction of the moral sentiments, among different ages and nations."

We may supplement this story by another from Herodotus (iii., 38):

"Darius, after he had got the kingdom, called into his presence certain Greeks who were at hand, and asked, 'What he should pay them to eat the bodies of their fathers when they died.' To which they answered, that there was no sum that would tempt them to do such a thing. He then sent for certain Indians, of the race called Callatians, men who eat their fathers, and asked them, while the Greeks were standing by, and knew by the aid of an interpreter all that was said--'What he should give them to burn the bodies of their fathers, at their decease?' The Indians exclaimed aloud, and bade him forbear such language. Such is the way of men; and Pindar was right in my judgment, when he said, 'Convention is king over all.'"

2. If any one held that the natural law of conscience was natural in the same way as the sense of temperature: if one held to the existence of a Moral Sense in all men, settling questions of right and wrong, as surely as all men know sweet things from bitter by tasting them: these stories, and they could be multiplied by hundreds, abundantly suffice to confute the error. There is no authentic copy of the moral law, printed, framed, and hung up by the hand of Nature, in the inner sanctuary of every human heart. Man has to learn his duties as he learns the principles of health, the laws of mechanics, the construction and navigation of vessels, the theorems of geometry, or any other art or science. And he is just as likely to go wrong, and has gone wrong as grievously, in his judgments on moral matters as on any other subject of human knowledge. The knowledge of duties is natural (as explained in the previous section, n. 2), not because it comes spontaneously, but because it is necessary to our nature for the development and perfection of the same. Thus a man ought, so far as he can, to learn his duties: but we cannot say of a man, as such, that he ought to learn geometry or navigation. If a man does not know his duties, he is excused by ignorance, according to the rules under which ignorance excuses (c. iii., s. i., nn. 3-5, p. 27). If a man does not know navigation, there is no question of excuse for what he was not bound to learn, but he may suffer loss by his want of knowledge.

3. It was furthermore observed above (l.c.), that the natural law was so called as being found expressed more or less perfectly in the minds of all men, and therefore being a proper element of human nature. It remains to see how much this universal natural expression amounts to. That is at once apparent from our previous explanation of synderesis. (s. i., nn. 5, seq., p. 139.) Not a complete and accurate knowledge of the natural law is found in all minds, far from it; but synderesis is found in all. This is apparent from Mr. Grote's own phrases, "aspirations of filial sentiment," "religious obligation," "honour as a patriot," Parents are to be honoured, we must do our duty to God and to our country: there Hannibal was at one with the most approved teachers of morality. Callatian and Greek agreed in the recognition of the commandment, Honour thy father and thy mother. That was the major premiss of them both, in the moral syllogism (s. i., n. 3, p. 135), which ruled their respective consciences. Their difference was upon the applying minor, as it is called; the Greek regarding the dissolution of the body into its elements by fire, and so saving it from corruption, as the best means of honouring the dead: the Callatians preferring to raise their parents as it were to life again, by making them the food of their living children. Hannibal, again, had before his mind the grand principle of retribution, that wrongdoing must be expiated by suffering. But he had not heard the words "Vengeance is Mine;" and mistakenly supposed it to rest with himself to appoint and carry out his own measure of revenge. Whether he was quite so invincibly ignorant on this point, as Grote represents, is open to doubt. At any rate he was correct in the primary moral judgment on which he proceeded.
