As there are different qualities of the sight, such as long and short sight, so there are different qualities of mind. There are minds which can see a certain distance and no further, and others that can see a longer distance; and what is called foresight is not a supernatural, superhuman faculty but a long range of sight. When one person can see the action of another person the seer can see the reason of the action too, and if the sight is keener still he can see the reason of the reason. One cannot give one's sight to another; he can tell what he sees, but that is not sufficient, for in order to be sure every soul wants its own experience.
