Wanting to test him, the king ordered waxen pomegranates to be set before them. When the wise man was deceived, the king cried out that he had assented to a false appearance. The wise man made a well-aimed reply to him, saying that he had assented in this way, not that they are pomegranates, but that it is probable that they are pomegranates, but the appearance which gives direct apprehension differs from the probable [appearance]."[2]
