Seneca, Moral Epistles 84
“I believe that these journeys which remove my languor are good for both my strength and my researches. How they profit my health is clear: my love of literature makes me lazy, neglectful of my body. On a journey, I may exercise incidentally.
I can show you how this helps my research too. But I in no way take a break from reading. My reading, I believe, is necessary: first, it ensures I will not be satisfied with myself as I am; second, once I have understood what others have learned, I may judge what has been discovered and what still must be thought out.
Reading feeds the mind and replenishes it when it is worn from studying—even though it is not without work itself. We should not restrict ourselves to writing or to reading: endless writing saps our strength and then exhausts it. Too much reading can puff up or dilute our ability. Most commendable is to take them in their turn, to mix one with the other, so that the seeds of one’s reading may be grown anew with the pen.”
Itinera ista, quae segnitiam mihi excutiunt, et valitudini meae prodesse iudico et studiis. Quare valitudinem adiuvent, vides: cum pigrum me et neglegentem corporis litterarum amor faciat, aliena opera exerceor; studio quare prosint, indicabo: a lectionibus nihil recessi. Sunt autem, ut existimo, necessariae, primum ne sim me uno contentus; deinde ut, cum ab aliis quaesita cognovero, tum et de inventis iudicem et cogitem de inveniendis. Alit lectio ingenium et studio fatigatum, non sine studio tamen, reficit. Nec scribere tantum nec tantum legere debemus; altera res contristabit vires et exhauriet, de stilo dico, altera solvet ac diluet. Invicem hoc et illo commeandum est et alterum altero temperandum, ut quicquid lectione collectum est, stilus redigat in corpus.
I was reminded of this passage while contemplating Paul Holdengraber’s regular injunction not to read bad writing:
As we have mentioned before, this resonates with Leonardo de Bruni’s warning about reading trash. Of course, the statement should probably be tempered by Pliny the Elder’s suggestion that “no book is so bad it doesn’t have something to offer”.
I feel that Seneca offers good advice for anyone working on a long project, but especially for graduate students or anyone working on a thesis. I know that the last line above is translated a little freely, but I have the following in my head. It is important to grow ideas in the garden of your mind.
