A quote
Yet what good will your indulgence do me, if, lo and behold, I can in no wise express in Latin the meaning of the word which gave me the opportunity to rail at the poverty of our language? And you will condemn our narrow Roman limits even more, when you find out that there is a word of one syllable which I cannot translate. “What is this?” you ask. It is the word ὄν. You think me lacking in facility; you believe that the word is ready to hand, that it might be translated by quod est. I notice, however, a great difference; you are forcing me to render a noun by a verb.
