Revenge is a sweet passion, of great and natural impression; I discern it well enough, though I have no manner of experience of it. From this not long ago to divert a young prince, I did not tell him that he must, to him that had struck him upon the one cheek, turn the other, upon account of charity; nor go about to represent to him the tragical events that poetry attributes to this passion. I left that behind; and I busied myself to make him relish the beauty of a contrary image: and, by representing to him what honour, esteem, and goodwill he would acquire by clemency and good nature, diverted him to ambition. Thus a man is to deal in such cases.
If your passion of love be too violent, disperse it, say they, and they say true; for I have often tried it with advantage: break it into several desires, of which let one be regent, if you will, over the rest; but, lest it should tyrannise and domineer over you, weaken and protract, by dividing and diverting it:
"Cum morosa vago singultiet inguine vena,"
["When you are tormented with fierce desire, satisfy it with the first person that presents herself."—Persius, Sat., vi. 73.]
"Conjicito humorem collectum in corpora quaeque,"
[Lucretius, vi. 1062, to the like effect.]
and provide for it in time, lest it prove troublesome to deal with, when it has once seized you:
"Si non prima novis conturbes vulnera plagis,
Volgivagaque vagus venere ante recentia cures."
["Unless you cure old wounds by new."-Lucretius, iv. 1064.]
I was once wounded with a vehement displeasure, and withal, more just than vehement; I might peradventure have lost myself in it, if I had merely trusted to my own strength. Having need of a powerful diversion to disengage me, by art and study I became amorous, wherein I was assisted by my youth: love relieved and rescued me from the evil wherein friendship had engaged me. 'Tis in everything else the same; a violent imagination hath seized me: I find it a nearer way to change than to subdue it: I depute, if not one contrary, yet another at least, in its place. Variation ever relieves, dissolves, and dissipates.
