Letter 71 — On the Supreme Good (§8)

“You may say: “What then? Is there no difference between Cato’s being elected praetor and his failure at the polls? Or whether Cato is conquered or conqueror in the battle-line of Pharsalia? And when Cato could not be defeated, though his party met defeat, was not this goodness of his equal to that which would have been his if he had returned victorious to his native land and arranged a peace?” Of course it was; for it is by the same virtue that evil fortune is overcome and good fortune is controlled. Virtue, however, cannot be increased or decreased; its stature is uniform.”
