And this Tully also shows in a letter to Nepos, in which he taxes Caesar with cruelty, saying: For happiness is nothing else than success in noble actions. Or, to express it differently, happiness is the good fortune that aids worthy designs, and one who does not aim at these can in no wise be happy. Therefore, in lawless and impious plans, such as Caesar followed, there could be no happiness. Happier, in my judgement, was Camillus in exile than was Manlius[*](M. Manlius saved the Roman citadel when the Gauls took the city in 387 B.C. Later, because he defended the commons, he was accused of aspiring to regal power and hurled from the Tarpeian Rock.) at that same time, even if (as he had desired) he had succeeded in making himself king.[*](A fragment preserved by Ammianus alone, not found in Cicero’s extant works.)
