Such is always the pursuit of knowledge. The celestial fruits, the golden apples of the Hesperides, are ever guarded by a hundred-headed dragon which never sleeps, so that it is an Herculean labor to pluck them.
Henry David ThoreauPaper is cheap, and authors need not now erase one book before they write another. Instead of cultivating the earth for wheat andpotatoes, they cultivate literature, and fill a place in the Republic of Letters. Or they would fain write for fame merely, as others actually raise crops of grain to be distilled into brandy.
Henry David Thoreau
