"The father is himself his children's tomb,"
that would seem improper, because we are told that they were just men. But when Atreus speaks those lines, they call forth applause; for the sentiment is in keeping with the character. But it will rest with the poets to decide, according to the individual characters, what is proper for each; but to us Nature herself has assigned a character of surpassing excellence, far superior to that of all other living creatures, and in accordance with that we shall have to decide what propriety requires.
98 The poets will observe, therefore, amid a great variety of characters, what is suitable and proper for all—even for the bad. |Moral propriety.| But to us Nature has assigned the rôles of steadfastness, temperance, self-control, and considerateness of others; Nature also teaches us not to be careless in our behaviour towards our fellow-men. Hence we may clearly see how wide is the application not only of that propriety which is essential to moral rectitude in general, but also of the special propriety which is displayed in each particular subdivision of virtue. For, as physical beauty with harmonious symmetry of the limbs engages the attention and delights the eye, for the very reason that all the parts combine in harmony and grace, so this propriety, which shines out in our conduct, engages the approbation of our fellow-men by the order, consistency, and self-control it imposes upon every word and deed.
Considerateness.
99 We should, therefore, in our dealings with people show what I may almost call reverence toward all men—not only toward the men who are the best, but toward others as well. For indifference to public opinion implies not merely self-sufficiency, but even total lack of principle. There is, too, a difference between justice and considerateness in one's relations to one's fellow-men. It is the function of justice not to do wrong to one's fellow-men; of considerateness, not to wound their feelings; and in this the essence of propriety is best seen.
With the foregoing exposition, I think it is clear what the nature is of what we term propriety.
Duties prescribed by propriety:
100 Further, as to the duty which has its source in propriety, the first road on which it conducts us leads to harmony with Nature and the faithful observance of her laws. |(1) Follow Nature,| If we follow Nature as our guide, we shall never go astray, but we shall be pursuing that which is in its nature clear-sighted and penetrating (Wisdom), that which is adapted to promote and strengthen society (Justice), and that which is strong and courageous (Fortitude). But the very essence of propriety is found in the division of virtue which is now under discussion (Temperance). For it is only when they agree with Nature's laws that we should give our approval to the movements not only of the body, but still more of the spirit.
(2) subject appetite to reason.
101 Now we find that the essential activity of the spirit is twofold: one force is appetite (that is, ὁρμή, in Greek), which impels a man this way and that; the other is reason, which teaches and explains what should be done and what should be left undone. The result is that reason commands, appetite obeys.
