Again, at this age it is necessary to its perfection to be Loving; because at this age it is requisite to look behind and before, as being midway over the arch. The youth ought to love his elders, from whom he has received his being, and his nutriment, and his instruction, so that he may not appear ungrateful. He ought to love his juniors, since, in loving them, he gives them of his good gifts, for which in after-years, when the younger friends are prospering, he may be supported and honoured by them. And the poet named above, in the fifth book before-mentioned, makes it evident that AEneas possessed this loving disposition, when he left the aged Trojans in Sicily, recommended to Acestes, and set them free from the fatigues of the voyage; and when he instructed, in the same place, Ascanius his son, with the other young men, in jousting or in feats of arms; wherefore it appears that to this age Love is necessary, even as the Song says.
Again, to this age Courtesy is necessary, for, although to every age it is right or beautiful to be possessed of courteous manners, to this age it is especially necessary, because, on the contrary, Old Age, with its gravity and its severity, cannot possess courtesy, if it has been wanting in this youthful period of life; and with Extreme Old Age it is the same in a greater degree. And that most noble poet, in the sixth book before-mentioned, proves that AEneas possessed this courtesy, when he says that AEneas, then King, in order to pay honour to the dead body of Misenus, who had been the trumpeter of Hector, and afterwards accompanied AEneas, made himself ready and took the axe to assist in cutting the logs for the fire which must burn the dead body, as was their custom. Wherefore this courtesy does indeed appear to be necessary to Youth; and therefore the noble Soul reveals it in that age, as has been said.
