["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 making 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.
