We believe, too, that a permanent reconciliation of bitter enmities is more likely to be secured, not when one party seeks revenge and, because he has gained a decided mastery in the war, tries to bind his opponent by compulsory oaths and thus makes peace with him on unequal terms, but when, having it in his power to secure the same result by clemency, he vanquishes his foe by generosity also, offering him terms of reconciliation which are moderate beyond all his expectations.
For the adversary, finding himself now under obligation to repay the generosity in kind, instead of striving for vengeance for having had terms forced upon him, is moved by a sense of honour and is more ready to abide by his agreements.
Furthermore, men are more inclined to act thus toward their more serious enemies than toward those with whom they have had but trifling differences. And, finally, it is natural for men cheerfully to accept defeat at the hands of those who first make willing concessions, but to fight to the bitter end, even contrary to their better judgment, against an overbearing foe.
"Now, if ever, reconciliation is desirable for us both, before some irreparable disaster has come upon either of us and prevented it; should that befall, we shall inevitably cherish toward each other an undying personal hatred, over and above that which we now feel as public enemies, and you[*](Or, reading ἀίδιον ὑμῖν. . . ἡμᾶς δέ, as Hude does, “you Athenians would have our undying hatred . . . and we Spartans would be deprived of the advantages we now offer.”) will be deprived of the advantages[*](ie. peace, alliance, intimate friendship (4.19.1).) we now offer.
While, therefore, the issue of the war is still in doubt, while your reputation is enhanced and you may have our friendship also, and while our disaster admits of a reasonable settlement and no disgrace as yet has befallen us, let us be reconciled; and let us for ourselves choose peace instead of war, and give a respite from evils to all the other Hellenes. And they will count you especially the authors of the peace; for although they were drawn into the war without knowing which of us began it, yet if a settlement is effected, the decision of which at this time rests chiefly with you, it is to you they will ascribe their gratitude.
