‹Note after Scholion XXIV›

Oh! It is definitely possible to be instructed by you teaching in a scientific manner, since surely it is only yourself who are familiar with the scientific method. It is therefore definitely possible for anyone to be instructed by your spirit, since surely it is only you who have the spiritual ear added to yourself by God, according to the saying, He attached an ear to me, to hear [as the learned]. For even irrational animals have the organ of the sense of hearing, whereas it is only the wise in spirit that have the ear of understanding, of which the Saviour spoke addressing the multitude, He that hath ears to hear, let him hear.
