he is my son, he is my brother; but he is passionate, ill-natured, or a fool.  And moreover, by how much these are friendships that the law and natural obligation impose upon us, so much less is there of our own choice and voluntary freedom; whereas that voluntary liberty of ours has no production more promptly and; properly its own than affection and friendship.  Not that I have not in my own person experimented all that can possibly be expected of that kind, having had the best and most indulgent father, even to his extreme old age, that ever was, and who was himself descended from a family for many generations famous and exemplary for brotherly concord: 

“Et ipse
Notus in fratres animi paterni.”

["And I myself, known for paternal love toward my brothers.” 
—­Horace, Ode, ii. 2, 6.]

We are not here to bring the love we bear to women, though it be an act of our own choice, into comparison, nor rank it with the others.  The fire of this, I confess,

                   “Neque enim est dea nescia nostri
                    Qux dulcem curis miscet amaritiem,”

["Nor is the goddess unknown to me who mixes a sweet bitterness
with my love.”—–­Catullus, lxviii. 17.]

is more active, more eager, and more sharp:  but withal, ’tis more precipitant, fickle, moving, and inconstant; a fever subject to intermissions and paroxysms, that has seized but on one part of us.  Whereas in friendship, ’tis a general and universal fire, but temperate and equal, a constant established heat, all gentle and smooth, without poignancy or roughness.  Moreover, in love, ’tis no other than frantic desire for that which flies from us: 

              “Come segue la lepre il cacciatore
               Al freddo, al caldo, alla montagna, al lito;
               Ne piu l’estima poi the presa vede;
               E sol dietro a chi fugge affretta il piede”

["As the hunter pursues the hare, in cold and heat, to the mountain,
to the shore, nor cares for it farther when he sees it taken, and
only delights in chasing that which flees from him.”—­Aristo, x. 7.]

so soon as it enters unto the terms of friendship, that is to say, into a concurrence of desires, it vanishes and is gone, fruition destroys it, as having only a fleshly end, and such a one as is subject to satiety.  Friendship, on the contrary, is enjoyed proportionably as it is desired; and only grows up, is nourished and improved by enjoyment, as being of itself spiritual, and the soul growing still more refined by practice.  Under this perfect friendship, the other fleeting affections have in my younger years found some place in me, to say nothing of him, who himself so confesses but too much in his verses; so that I had both these passions, but always so, that I could myself well enough distinguish them, and never in any degree of comparison with one another; the first maintaining its flight in so lofty and so brave a place, as with disdain to look down, and see the other flying at a far humbler pitch below.
