Seneca, Moral Epistle 106.11-12
“In sum, whatever we do we are compelled to do by either malice or virtue. What controls a body, is corporeal; what gives force to a body is a body. The good of a body is corporeal good; the good of a person is the good of a body—therefore it too is corporeal.
Since I have pursued this custom as you wanted, now I myself will say what I expect you to say: “we have been playing games!” Our wit is worn thing by silly things—they make us learned but not good. To be wise is a more obvious matter—it is much better to use literature to improve the mind, but we waste the rest of our time in empty matters, and so we waste philosophy itself. Just as in all things, so too we labor excessively over literature. We learn not for life but for school. Goodbye.”
Denique quidquid facimus, aut malitiae aut virtutis gerimus imperio. Quod imperat corpori, corpus est, quod vim corpori adfert, corpus. Bonum corporis corporalest,bonum hominis et corporis bonum est; itaque corporale est.
11Quoniam, ut voluisti, morem gessi tibi, nunc ipse dicam mihi, quod dicturum esse te video: latrunculis ludimus. In supervacuis subtilitas teritur; non faciunt bonos ista, sed doctos. Apertior res est sapere, immo simpliciter satius est ad mentem bonam uti litteris, sed nos ut cetera in supervacuum diffundimus, ita philosophiam ipsam. Quemadmodum omnium rerum, sic litterarum quoque intemperantia laboramus; non vitae sed scholae discimus. Vale.
