Vergerio, de ingenuis moribus et liberalibus adulescentiae studiis, LIV:
“Everything will turn out well enough if our time is disposed of properly, if we on every day give fixed hours to the pursuit of literature, and he we are never dragged away by any business which prevents us from reading something every day. For, if Alexander was in the habit of reading much in his camp, and if Caesar wrote books as he was setting off with his army, and if Augustus after undertaking something so great in the Battle of Mutina nevertheless always read or wrote or declaimed every day in his tent, what could come upon us in our urban leisure which could call us far off from the study of literature? It is useful, however, for us to consider even the smallest loss of time as a great one; we should also keep an account of our time, just as we do of our life and health, so that nothing is uselessly lost, as when we commit our idle hours, (and those which others commit to leisure) to lighter studies or a bit of pleasant reading.”
Fient autem commode omnia si rite tempora dispensabuntur, si singulis diebus statutas horas litteris dabimus, neque ullo negotio abstrahemur quominus aliquid quotidie legamus. Nam si Alexander in castris lectitare plurimum solebat, si Caesar etiam cum exercitu proficiscens libros scribebat, et Augustus Mutinensi bello rem tantam adortus, semper tamen in castris legere aut scribere quotidieque declamitare consueverat, quid poterit urbano otio intervenire quod nos diu prorsus a litterarum studiis avocet? Utile autem est, ut vel cuiuslibet minimi temporis iacturam pro magna deputemus, et ita temporis, quemadmodum et vitae ac salutis, rationem habeamus, ut nihil inutiliter nobis depereat, veluti si inertes horas et quae apud ceteros otiosae sunt aut studiis levioribus dabimus aut lectione iucunda transigemus.
