“There were two opposing concepts. Chrysippus the philosopher intermingled not merely passages from other authors into his writings but entire books: in one he cited the whole of the Medea of Euripides! Apollodorus said that if you cut out his borrowings his paper would remain blank. Epicurus on the other hand left three hundred tomes behind him: not one quotation from anyone else was planted in any of them. The other day I chanced upon such a borrowing. I had languished along behind some French words, words so bloodless, so fleshless and so empty of matter that indeed they were nothing but French and nothing but words.”
