Plutarch De Genio Socratis 3

[3] But Theocritus the soothsayer, grasping me by the hand, and looking on Charon that went just before us, said: That Charon, Caphisias, is no philosopher, nor so general nor so acute a scholar as thy brother Epaminondas, and yet you see that, Nature leading him, under the direction of the law, to noble actions, he willingly ventures on the greatest danger for the benefit of his country; but Epaminondas, who thinks he knows more of virtue than any of the Boeotians, is dull and inactive; and though opportunity presents, though there cannot be a fairer occasion, and though he is fitted to embrace it, yet he refuseth to join, and will not make one in this generous attempt. And I replied: Courageous Theocritus, we do what upon mature deliberation we have approved, but Epaminondas, being of a contrary opinion and thinking it better not to take this course, rationally complies with his judgment, whilst he refuseth to meddle in those matters which his reason upon our desire cannot approve, and to which his nature is averse. Nor can I think it prudent to force a physician to use fire and a lancet, that promiseth to cure the disease without them. What, said Theocritus, doth he not approve of our method No, I replied, he would have no citizens put to death without a trial at law; but if we would endeavor to free our country without slaughter and bloodshed, none would more readily comply; but since we slight his reasons and follow our own course, he desires to be excused, to be guiltless of the blood and slaughter of his citizens, and to be permitted to watch an opportunity when he may deliver his country according to equity and right. For this action may go too far, Pherenicus, it is true, and Pelopidas may assault the bad men and the oppressors of the people; but Eumolpidas and Samidas, men of extraordinary heat and violence, prevailing in the night, will hardly sheathe their swords until they have filled the whole city with slaughter and cut in pieces many of the chief men.
