And yet from such an enterprise I for my part get honour, and have less dread than others about my life,[*](He may have been suffering already from the kidney trouble of which he complained the next summer in his letter to the Athenians (7.15.1).) although I consider that he is quite as good a citizen who takes some forethought for his life and property; for such an one would, for his own sake, be most desirous that the affairs of the city should prosper. But nevertheless neither in the past have I, for the sake of being preferred in honour, spoken contrary to my judgment, nor shall I do so now, but I shall speak just as I deem best.
Against tempers, indeed, like yours my words would be unavailing, if I should exhort you to preserve what you have already and not to hazard present possessions for things that are unseen and in the future; that, however, neither is your haste timely, nor is it easy to attain what you are striving for, this I shall show.
"I say, then, that you, leaving behind you many enemies here, are bent upon sailing there land bringing upon you here still other enemies.
And you think perhaps that the treaty which has been made affords you some security—a treaty which indeed, as long as you are quiet, will be a treaty in name (for so certain men here and among our enemies have managed these matters); but should you perchance suffer defeat with a considerable force, our foes will be quick to make their attack upon us. For the compact in the first place was concluded by them under compulsion through stress of misfortune and with less credit to them than to us; and, besides, in the compact itself there are many disputed points.
There are also some states which have not as yet accepted even this agreement, and these not the weakest; on the contrary, some of them are at open war with us, while others again, merely because the Lacedaemonians still keep quiet, are themselves also kept in restraint by a truce renewable every ten days.
But very probably, if they should find our power divided—the very thing we are now so anxious to bring about—they would eagerly join in an attack upon us along with the Siceliots, whose alliance they would heretofore have given much to obtain.
