You have promised to be a good man

You have promised to be a good man; you have enlisted under oath; that is the strongest chain which will hold you to a sound understanding. Any man will be but mocking you, if he declares that this is an effeminate and easy kind of soldiering. I will not have you deceived. The words of this most honourable compact are the same as the words of that most disgraceful one, to wit: “Through burning, imprisonment, or death by the sword."

From the men who hire out their strength for the arena, who eat and drink what they must pay for with their blood, security is taken that they will endure such trials even though they be unwilling; from you, that you will endure them willingly and with alacrity. The gladiator may lower his weapon and test the pity of the people; but you will neither lower your weapon nor beg for life. You must die erect and unyielding. Moreover, what profit is it to gain a few days or a few years? There is no discharge for us from the moment we are born.

“Then how can I free myself?" you ask. You cannot escape necessities, but you can overcome them.

Seneca, Letter 37 to Lucilius
