“17. There are eight organs of knowledge: sense, imagination, art, opinion, deliberation, science, wisdom and mind. Art, prudence, science and mind we share with the Gods; sense and imagination, with the irrational animals; while opinion alone is our characteristic. Sense is a fallacious knowledge derived through the body; imagination is a notion in the soul; art is a habit of cooperating with reason. The words “with reason” are here added, for even a spider operates, but it lacks reason. Deliberation is a habit selective of the rightness of planning deeds; science is a habit of those things which remain ever the same, with Sameness; wisdom is a knowledge of the first causes; while Mind is the principle and fountain of all good things.”
