["We carry intemperance into the study of literature, as well as into everything else."--Seneca, Ep., 106.] And Tacitus had reason to commend the mother of Agricola for having restrained her son in his too violent appetite for learning. Tis a good, if duly considered, which has in it, as the other goods of men have, a great deal of vanity and weakness, proper and natural to itself, and that costs very dear. Its acquisition is far more hazardous than that of all other meat or drink; for, as to other things, what we have bought we carry home in some vessel, and there have full leisure to examine our purchase, how much we shall eat or drink of it, and when: but sciences we can, at the very first, stow into no other vessel than the soul; we swallow them in buying, and return from the market, either already infected or amended: there are some that only burden and overcharge the stomach, instead of nourishing; and, moreover, some that, under colour of curing, poison us. I have been pleased, in places where I have been, to see men in devotion vow ignorance as well as chastity, poverty, and penitence: 'tis also a gelding of our unruly appetites, to blunt this cupidity that spurs us on to the study of books, and to deprive the soul of this voluptuous complacency that tickles us with the opinion of knowledge: and 'tis plenarily to accomplish the vow of poverty, to add unto it that of the mind. We need little doctrine to live at our ease; and Socrates teaches us that this is in us, and the way how to find it, and the manner how to use it: All our sufficiency which exceeds the natural is well-nigh superfluous and vain: 'tis much if it does not rather burden and cumber us than do us good: "Paucis opus est literis ad mentem bonam:" ["Little learning is needed to form a sound mind." --Seneca, Ep., 106.]
