This oneness of the active intellect, or reason, is the essential principle of the Averroistic theory, and is in harmony with the cardinal doctrine of Mohammedanism--the unity of God.
The individual, or passive, or subjective intellect, is an emanation from the universal, and constitutes what is termed the soul of man.

In one sense it is perishable and ends with the body, but in a higher sense it endures; for, after death, it returns to or is absorbed in the universal soul, and thus of all human souls there remains at last but one--the aggregate of them all, life is not the property of the individual, it belongs to Nature.

The end of, man is to enter into union more and more complete with the active intellect--reason.

In that the happiness of the soul consists.

Our destiny is quietude.
