Ante senectutem curavi ut bene viverem, in senectute ut bene moriar; bene autem mori est libenter mori. - Seneca

And this is the vote which [Cato] casts concerning them both: “If Caesar wins, I slay myself; if Pompey, I go into exile.” What was there for a man to fear who, whether in defeat or in victory, had assigned to himself a doom which might have been assigned to him by his enemies in their utmost rage? So he died by his own decision.

It would be some consolation for the feebleness of ourselves and our works, if all things should perish as slowly as they come into being; but as it is, increases are of sluggish growth, but the way to ruin is rapid.

No one ever saw Cato change, no matter how often the state changed: he kept himself the same in all circumstances—in the praetorship, in defeat, under accusation, in his province, on the platform, in the army, in death.
