God himself, or the First Essence, can be known only through the Will as pervading everything, i. e., through his effects in the world. And in this way too only his existence can be known but not his essence as he is in himself, because God is above everything and infinite. The soul may know Intelligence because though the latter is above the soul there is some similarity between them. But the First Essence has no similarity to Intelligence, therefore no intelligence can know it.

There is a kind of mystic knowledge by which man may come in touch with the spiritual substances and rise even to universal matter, which is above Intelligence. "If you wish to form a picture of these substances," the master says to the disciple in the "Fons Vitæ," "you must raise your intellect to the last intelligible, you must purify it from all sordid sensibility, free it from the captivity of nature and approach with the force of your intelligence to the last limit of intelligible substance that it is possible for you to comprehend, until you are entirely divorced from sensible substance and lose all knowledge thereof. Then you will embrace, so to speak, the whole corporeal world in your being, and will place it in one corner of your soul. When you have done this you will understand the insignificance of the sensible in comparison with the greatness of the intelligible. Then the spiritual substances will be before your eyes, comprehending you and superior to you, and you will see your own being as though you were those substances. Sometimes it will seem to you that you are a part of them by reason of your connection with corporeal substance; and sometimes you will think you are all of them, and that there is no difference between you and them, on account of the union of your being with their being, and the attachment of your form to their forms." The pupil assures the teacher that he has followed this advice and seen the whole corporeal world floating in the spiritual substances as a small boat in the sea, or a bird in the air. "When you have raised yourself to the first universal matter," replies the teacher, "and illumined its shadow, you will see there the wonder of wonders. Pursue this therefore diligently and with love, because this is the purpose of the existence of the human soul, and in this is great delight and extreme happiness."[102]

But Gabirol does not promise a knowledge of the Most High even through this royal road of ecstasy, unless we suppose that in the promise of seeing in universal matter the wonder of all wonders there may be a covert allusion to a glimpse of the deepest secret of all, the essence of God.

All knowledge is according to Gabirol embraced in the following three topics, (1) Matter and Form, (2) the Active Word or Will, (3) the First Essence or God. By far the larger part of the "Fons Vitæ" is devoted to the first subject. Only brief hints are given of the second and third, and Gabirol refers us to a special work of his on the Will, which he says he wrote. There is no trace of any such treatise. At any rate it is clear from the little that is contained on the Divine Will in the "Fons Vitæ" that the Will forms an important element in Gabirol's philosophy. This is the more remarkable because it is not an essential element in Neo-Platonism, upon which Gabirol's system is based. Nay, the doctrine of a divine will scarcely has any place in the form of emanation taught by Plotinus. The cosmic process is conceived there as necessary and impersonal. And but for the introduction of the Will in the "Fons Vitæ" we should be forced to understand Gabirol in the same way. The difficulty in Neo-Platonism is that God is at the same time transcendent and, through his powers or emanations, immanent in the world. God is above all being and at the same time is the cause of and pervades all existence. Gabirol must have felt not merely this purely philosophical difficulty, but as a Jew, Pantheism as well as impersonalism must have been objectionable to him. Hence he mitigates both by introducing the divine will as mediating between God and the world. This brings God in closer and more personal touch with his creation. The cosmic process is not a necessary and impersonal flow or radiation but a voluntary activity having a purpose. The solution is unsatisfactory, as all such solutions are bound to be, because it introduces as many difficulties as it solves. The nature of this divine Will is ambiguous. If it is God's will, and God is the One in whom there can be no distinctions, we have only a new word, and nothing is solved. If on human analogy we are inclined to take the will seriously, we are endangering God's unity. This dilemma Gabirol does not succeed in removing. His system still has a strong flavor of Pantheism, and moreover his identification of the Will of God with the Wisdom and the Word of God, and his hypostatization of the latter as in a sense a being distinct from God, reminds us strongly of Philo's Logos, which became the Logos of Christianity, the second person in the Trinity. This is the reason why William of Auvergne, bishop of Paris in the thirteenth century, regarded Avicebron as a Christian. And these same reasons were no doubt adequate to estrange Jewish readers, as Abraham ibn Daud expressly tells us about himself, though his terms are general (see above, p. [62]).

Gabirol is also the author of an ethical work which he composed in 1045. Though of little importance philosophically, or perhaps because of this, the "Tikkun Middot ha-Nefesh" (Improvement of the Qualities of the Soul) fared much better than its more important companion, the "Mekor Hayim." Not only did it have the privilege of a Hebrew translation at the hands of the father of translators, Judah ibn Tibbon, but the original Arabic itself is still extant and was recently published with an English translation by Stephen S. Wise (1901).[103] The Hebrew translation also had the good fortune of being reprinted several times. This is due to the fact that the "Tikkun Middot ha-Nefesh" is a popular work, dealing with morals, and does not go into metaphysical questions. It is full of Biblical citations, which stamps it as Jewish; and there are also in it quotations from Arabic writers serving to illustrate the argument and lending variety and interest to the style.

The larger question of the aim of human life is touched on in the "Fons Vitæ." 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.[104] 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 themselves; 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 intelligible 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 qualities, hot, cold, moist, dry. This division of the elements, the humors, the qualities and the senses was a commonplace of the physiological 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 these. The approximations are forced in every instance and often ludicrous. Instead of attempting to give a psychological analysis of the qualities in question, he lays stress on their physical basis in one of the five senses, as we shall see presently.

The great world, we are told, was created out of the four elements, and similarly man, the microcosm, also consists of four natures corresponding to the elements. Thus the four humors, upon the harmonious combination of which the health of man's body depends, viz., blood, phlegm, black gall, and red gall, correspond respectively to air, water, earth, fire. Man is endowed besides with five senses. If he is wise he will use his senses properly and in the right measure, like a skilful physician who calculates carefully what proportion of each drug should be prescribed.

The sense of sight is the noblest of the senses, and is related to the body as the sun to the world. The philosophers have a wonderful saying concerning the eye that there are spiritual tints in the soul which are visible in the movements of the eyelids—pride and haughtiness, humility and meekness. Accordingly the ethical qualities due to the sense of sight are pride, meekness, modesty and impudence, besides the subordinate qualities derived from these.

Pride is common in a person of a warm disposition in whom the red gall predominates. Many wise men exhibit this quality out of place, fools adopt it until they are mastered by it, and it is prevalent in youth. It may be useful when it keeps a man away from vice and unworthy things, inspiring him to rise to nobility of character and the service of God. But generally it is useless and leads to many evils, especially if it causes one to be self-opinionated, refusing to seek the advice of anyone. When a man sees this quality gaining mastery over him, he should consider the origin and end of existing things. When he sees that all things are destined to pass away, and himself likewise, his pride will change to humility.
