" Fons Vitae." We are told there that the ultimate aim of man's existence is that the soul should unite with the upper world to which it belongs. -^^^ The particular human soul is according to Gabirol a part, though not in a physical sense, of the cosmic soul, which is one of the universal spiritual substances (see above, p. 66). Hence its own real existence is spiritual and eternal, and independent of the body. Its entrance into the body obscures its spiritual vision, though it does not lose all touch with the higher world from which it came. The senses and the data of sense perception are not an end in them- selves; they are only a means for the soul through them to recall the higher knowledge which was its own in its spiritual existence, and thereby win its return to the inteUigible world. Man's duty therefore in this world is to strive to attain this higher life for his soul. This is brought about by means of knowledge and practice. This knowledge has to do with knowing all things as they really are, and particularly the intelligible substances and the Prime Essence. Practice signifies to keep away as far as possible from things of sense, which are foreign to the soul and might injure it. What more particularly the things are which are beneficial to the soul, and what are injurious, we learn from Gabirol's ethical treatise. Man's soul has a higher and a lower nature. The higher power is the reason or rational soul, the lower is the animal or vegetative soul; and man's business is to see that the reason rules over the lower nature.

Gabirol does not give us any test by which we can tell whether a given act or feeling belongs to the lower or higher nature except to say that the appetites are diseases of the body which must be cured; that they do not belong to the rational soul, and to satisfy them is not the attainment of a good. Gabirol's method of treating virtue and vice, or rather the virtues and the vices, is to relate them to the five senses and the four humors in man, which in turn correspond to the four elements, fire, air, water, earth, and the four primitive quahties, hot, cold, moist, dry. This division of the elements, the humors, the qualities and the senses was a commonplace of the phys- iological and medical science of the time. We have met it in Isaac Israeli (see above, p. 3), and it goes back to Aristotle and Galen and Hippocrates. The originality, though a queer one to be sure, of Gabirol is to bring the ethical qualities of man into relation with all
