Context

“But since they do not regard every virtue as a mean, nor call it moral, we must discuss this difference by approaching the matter more from first principles. Some things in the world exist absolutely, as the earth, the sky, the stars, and the sea; others have relation to us, as good and evil, as what is desirable or to be avoided, as pleasant and painful: and since reason has an eye to both of these classes, when it considers the former it is scientific and contemplative, when it considers the latter it is deliberative and practical. And prudence is the virtue in the latter case, as knowledge in the former.” source
