Book 10
3.23
Personally I regard such an environment as a pleasant luxury rather than a stimulus to study. For whatever causes us delight, must necessarily distract us from the concentration due to our work. The mind cannot devote its undivided and sincere attention to a number of things at the same time, and wherever it turns its gaze it must cease to contemplate its appointed task.
3.24
Therefore, the charm of the woods, the gliding of the stream, the breeze that murmurs in the branches, the song of birds, and the very freedom with which our eyes may range, are mere distractions, and in my opinion the pleasure which they excite is more likely to relax than to concentrate our attention.
3.25
Demosthenes took a wiser view; for he would retire to a place An underground room. See Plut. Dem. vii. where no voice was to be heard, and no prospect greeted the sight, for fear that his eyes might force his mind to neglect its duty. Therefore, let the burner of the midnight oil seclude himself in the silence of night, within closed doors, with but a solitary lamp to light his labours.
3.26
But for every kind of study, and more especially for night work, good health and its chief source, simple living, are essential; for we have fallen into the habit of devoting to relentless labour the hour which nature has appointed for rest and relaxation. From those hours we must take only such time as is superfluous for sleep, and will not be missed.
