Plutarch explains classical education well in Moralia, “On the Education of Children”:
“There must be a concurrence of three things in order to produce perfectly right action, and these are: nature, reason, and habit. By reason I mean the act of learning, and by habit constant practice. The first beginnings come from nature, advancement from learning, the practical use from continued repetition, and the culmination from all combined; but so far as any one of these is wanting, the moral excellence must, to this extent, be crippled. For nature without learning is a blind thing, and learning without nature is an imperfect thing, and practice without both is an ineffective thing. Just as in farming, first of all the soil must be good, secondly, the husbandman skilful, and thirdly, the seed sound, so, after the same manner, nature is like to the soil, the teacher to the farmer, and the verbal counsels and precepts like to the seed… to sum up, the beginning, the middle, and end in all these matters is good education and proper training; and it is this, I say, which leads on and helps towards moral excellence and towards happiness… But learning, of all things in this world, is alone immortal and divine.”
