Plutarch, De fraterno amore
Goodwin, Ed.

I remember, when I was at Rome, I undertook an umpirage between two brothers. The one pretended to the study of philosophy, but (as it appeared by the event) with as little reason as to the relation of a brother. For, when I advised him that now was the time for him to show his philosophy, in the prudent managery and government of himself, whilst he was to treat with so dear a relation as a brother, and such a one especially as wanted those advantages of knowledge and education that he had; Your counsel, replied my philosopher, may do well with some illiterate novice or other; but, for my part, I see no such great matter in that which you so gravely allege, our being the issue of the same parents. True, I answered, you declare evidently enough that you make no account of your [p. 40] affinity. But, by your favor, Mr. Philosopher, all of your profession that I ever was acquainted with, whatever their private opinions were, affirm both in their prose and poetry that, next to the Gods and the laws, her conservators and guardians, Nature had assigned to parents the highest honor and veneration. And there is nothing that men can perform more grateful to the Gods, than freely and constantly to pay their utmost acknowledgments and thanks to their parents, and those from whom they received their nurture and education; as, on the other hand, there is no greater argument of a profane and impious spirit than a contemptuous and surly behavior towards them. We are therefore enjoined to take heed of doing any one wrong. But he that demeans not himself with that exactness before his parents that all his actions may afford them a pleasure and satisfaction, though he give them no other distaste, is sure to undergo a very hard censure. Now what can more effectually express the gratitude of children to their parents, or what actions or dispositions in their children can be more delightful and rejoicing, than firm love and amity amongst them?
