“Tell me, Anselmo, if Heaven or good fortune had made thee master and lawful owner of a diamond of the finest quality, with the excellence and purity of which all the lapidaries that had seen it had been satisfied, saying with one voice and common consent that in purity, quality, and fineness, it was all that a stone of the kind could possibly be, thou thyself too being of the same belief, as knowing nothing to the contrary, would it be reasonable in thee to desire to take that diamond and place it between an anvil and a hammer, and by mere force of blows and strength of arm try if it were as hard and as fine as they said? And if thou didst, and if the stone should resist so silly a test, that would add nothing to its value or reputation; and if it were broken, as it might be, would not all be lost? Undoubtedly it would, leaving its owner to be rated as a fool in the opinion of all.
