Letter 88 — On Liberal and Vocational Studies (§21)

“Posidonius divides the arts into four classes: first we have those which are common and low, then those which serve for amusement, then those which refer to the education of boys, and, finally, the liberal arts. The common sort belong to workmen and are mere hand-work; they are concerned with equipping life; there is in them no pretence to beauty or honour.”
