We can say, Cicero says thus; these were the manners of Plato; these are the very words of Aristotle: but what do we say ourselves? What do we judge? A parrot would say as much as that.
And this puts me in mind of that rich gentleman of Rome,--[Calvisius Sabinus. Seneca, Ep., 27.]-- who had been solicitous, with very great expense, to procure men that were excellent in all sorts of science, whom he had always attending his person, to the end, that when amongst his friends any occasion fell out of speaking of any subject whatsoever, they might supply his place, and be ready to prompt him, one with a sentence of Seneca, another with a verse of Homer, and so forth, every one according to his talent; and he fancied this knowledge to be his own, because it was in the heads of those who lived upon his bounty; as they also do, whose learning consists in having noble libraries. I know one, who, when I question him what he knows, he presently calls for a book to shew me, and dares not venture to tell me so much, as that he has piles in his posteriors, till first he has consulted his dictionary, what piles and what posteriors are.
We take other men's knowledge and opinions upon trust; which is an idle and superficial learning. We must make it our own. We are in this very like him, who having need of fire, went to a neighbour's house to fetch it, and finding a very good one there, sat down to warm himself without remembering to carry any with him home.--[Plutarch, How a Man should Listen.]-- What good does it do us to have the stomach full of meat, if it do not digest, if it be not incorporated with us, if it does not nourish and support us? Can we imagine that Lucullus, whom letters, without any manner of experience, made so great a captain, learned to be so after this perfunctory manner? --[Cicero, Acad., ii. I.]-- We suffer ourselves to lean and rely so strongly upon the arm of another, that we destroy our own strength and vigour. Would I fortify myself against the fear of death, it must be at the expense of Seneca: would I extract consolation for myself or my friend, I borrow it from Cicero. I might have found it in myself, had I been trained to make use of my own reason.
I do not like this relative and mendicant understanding; for though we could become learned by other men's learning, a man can never be wise but by his own wisdom:
["I hate the wise man, who in his own concern is not wise."-- Euripides, ap. Cicero, Ep. Fam., xiii. 15.]
Whence Ennius:
"Nequidquam sapere sapientem, qui ipse sibi prodesse non quiret."
["That wise man knows nothing, who cannot profit himself by his wisdom."--Cicero, De Offic., iii. 15.]
"Si cupidus, si Vanus, et Euganea quantumvis mollior agna."
["If he be grasping, or a boaster, and something softer than an Euganean lamb."--Juvenal, Sat., viii. 14.]
"Non enim paranda nobis solum, sed fruenda sapientia est."
[" For wisdom is not only to be acquired, but to be utilised."--Cicero, De Finib., i. I.]
Dionysius --[It was not Dionysius, but Diogenes the cynic. Diogenes Laertius, vi. 27.]-- laughed at the grammarians, who set themselves to inquire into the miseries of Ulysses, and were ignorant of their own; at musicians, who were so exact in tuning their instruments, and never tuned their manners; at orators, who made it a study to declare what is justice, but never took care to do it. If the mind be not better disposed, if the judgment be no better settled, I had much rather my scholar had spent his time at tennis, for, at least, his body would by that means be in better exercise and breath. Do but observe him when he comes back from school, after fifteen or sixteen years that he has been there; there is nothing so unfit for employment; all you shall find he has got, is, that his Latin and Greek have only made him a greater coxcomb than when he went from home. He should bring back his soul replete with good literature, and he brings it only swelled and puffed up with vain and empty shreds and patches of learning; and has really nothing more in him than he had before.--[Plato's Dialogues: Protagoras.]
These pedants of ours, as Plato says of the Sophists, their cousin-germans, are, of all men, they who most pretend to be useful to mankind, and who alone, of all men, not only do not better and improve that which is committed to them, as a carpenter or a mason would do, but make them much worse, and make us pay them for ****** them worse, to boot. If the rule which Protagoras proposed to his pupils were followed--either that they should give him his own demand, or make affidavit upon oath in the temple how much they valued the profit they had received under his tuition, and satisfy him accordingly--my pedagogues would find themselves sorely gravelled, if they were to be judged by the affidavits of my experience. My Perigordin patois very pleasantly calls these pretenders to learning, 'lettre-ferits', as a man should say, letter-marked--men on whom letters have been stamped by the blow of a mallet. And, in truth, for the most part, they appear to be deprived even of common sense; for you see the husbandman and the cobbler go simply and fairly about their business, speaking only of what they know and understand; whereas these fellows, to make parade and to get opinion, mustering this ridiculous knowledge of theirs, that floats on the superficies of the brain, are perpetually perplexing, and entangling themselves in their own nonsense.
They speak fine words sometimes, 'tis true, but let somebody that is wiser apply them. They are wonderfully well acquainted with Galen, but not at all with the disease of the patient; they have already deafened you with a long ribble-row of laws, but understand nothing of the case in hand; they have the theory of all things, let who will put it in practice.
