Seneca · On Baiae and morals
Letters 51.9
I have set freedom before my eyes; and I am striving for that reward. And what is freedom, you ask? It means not being a slave to any circumstance, to any constraint, to any chance; it means compelling Fortune to enter the lists on equal terms. And on the day when I know that I have the upper hand, her power will be naught. When I have death in my own control, shall I take orders from her?
Seneca, Letters to Lucilius 51.9, translated by Richard Mott Gummere
