Moral Letters to Lucilius Section 16

Praeterea si non contemnit venientes extrinsecus causas et aliquid timet, cum fortiter eundum erit adversus tela, ignes, pro patria, legibus, libertate, cunctanter exibit et animo recedente. Non cadit autem in sapientem haec diversitas mentis.

qui ne méprise pas les accidents du dehors craint donc quelque chose ; et lorsqu’il faudra braver hardiment et en face les glaives et les feux pour la patrie, les lois, la liberté, il marchera de mauvaise grâce et à contre-cœur. Le sage ne tombera jamais dans cette discordance de sentiments.

Besides, if the wise man, instead of despising all causes that come from without, ever fears anything, when the time arrives for him to go bravely to meet the spear, or the flames, on behalf of his country, his laws, and his liberty, he will go forth reluctantly and with flagging spirit. Such inconsistency of mind, however, does not suit the character of a wise man.
