“People talk of keeping au courant, and no doubt an intellectual cannot ignore the human race, nor be indifferent to what is written in his special field; but take care lest the current should carry away with it all your capacity for work, and, instead of bearing you onwards, prevent you from making any headway against it….
What you must principally cut down is the less solid and serious kind of reading. There must be no question at all of poisoning your mind with novels. One from time to time, if you like, as a recreation and not to neglect some literary glory, but that is a concession; for the greater number of novels upset the mind without refreshing it; they disturb and confuse one’s thoughts.
As to newspapers, defend yourself against them with the energy that the continuity and the indiscretion of their assault make indispensable. You must know what the papers contain, but they contain so little; and it would be easy to learn it all without settling down to interminable lazy sittings!…
A serious worker should be content, one would think, with the weekly or bi-monthly chronicle in a review; and for the rest, with keeping his ears open, and turning to the daily papers only when a remarkable article or a grave event is brought to his notice.”
—A. G. Sertillanges, O.P., from The Intellectual Life: Its Spirit, Conditions, Methods (first published in 1921)
