In this way duality in nature is produced. From this comes "I and you." But as "I" is the first conception of the soul, it is fully concerned with this "I"; with all else it is only partly concerned. All other things that exist, besides this body which it has recognized as its own being, are considered according to their relation with this body. This relation is established by calling them "mine", which is between "I" and "you': "You are "my"" brother, or "my" sister, or "my" friend." This makes a relationship, and according to this relationship the other object or person stands nearer to or farther from the soul.
