QUALITIES ARE CLASSIFIED AS CORPOREAL AND OF THE SOUL.
17. Qualities, therefore, should be classified as of the body, and of the soul.[406] Even though all the souls, as well as their immaterial qualities, be considered as existing on high, yet their inferior qualities must be divided according to the senses, referring these qualities either to sight, hearing, feeling, taste, or smell. Under sight, we will classify the differences of colors; under hearing, that of the sounds; and likewise, with the other senses. As to the sounds, inasmuch as they have but a single quality, they will have to be classified according to their being soft, harsh, agreeable, and the like.
