Seneca · On liberal and vocational studies
Letters 88.3
The scholar busies himself with investigations into language, and if it be his desire to go farther afield, he works on history, or, if he would extend his range to the farthest limits, on poetry. But which of these paves the way to virtue? Pronouncing syllables, investigating words, memorizing plays, or making rules for the scansion of poetry,—what is there in all this that rids one of fear, roots out desire, or bridles the passions?
Seneca, Letters to Lucilius 88.3, translated by Richard Mott Gummere
