In Bahya's treatment of the divine attributes we already have in brief the main elements which Maimonides almost a century later made classic, namely, the distinction between essential and active attributes, and the idea that the former are to be understood as denying their opposites, i. e., as being in their nature not positive but negative. The outcome therefore is that only two kinds of attributes are applicable to God, negative and those which are transferred or projected from the effects of God's activity as they are visible in nature. Saadia had already made the distinction between essential and active attributes, but it was quite incidental with him, and not laid down at the basis of his discussion, but casually referred to in a different connection. Al Mukammas speaks of negative attributes as being more applicable to God than positive, as Philo had already said long before. But the combination of these two, negative and active, as the only kinds of divine attributes is not found in Jewish literature before Bahya.

It is worth noting also that Bahya does not lay down the three attributes, Power, Wisdom and Life as fundamental or essential in the manner of the Christians, the Arab Mutakallimun, and the Jewish Saadia. Bahya, as we have seen, regards as God's essential attributes, existence, unity, eternity. Herein, too, he seems to anticipate Maimonides who insists against the believers in essential attributes that the attributes, living, omnipotent, omniscient, having a will, are no more essential than any other, but like the rest of the qualities ascribed to God have reference to his activity in nature.[119]

We have now gone through Bahya's philosophical chapter giving us the metaphysical basis of his ethico-religious views. That his purpose is practical and not theoretical is clear from his definition of what he calls the "acknowledgment of the unity of God with full heart," not to speak of the title of the book itself, the meaning of which we explained at the beginning of this section, and the nine chapters in Bahya's work following upon the first, which constitute its real essence and purpose. To acknowledge the unity of God with full heart means, he tells us, that one must first know how to prove the existence and unity of God, to distinguish God's unity from every other, and then to make his heart and his tongue unite in this conception.[120] It is not a matter of the intellect merely, but of the heart as affecting one's practical conduct. The adequacy of the conception is destroyed not merely by thinking of God as multiple, or by worshiping images, sun, moon and stars; it is made null and void likewise by hypocrisy and pretence, as when one affects piety before others to gain their favor or acquire a reputation. The same disastrous result is brought about by indulging the low physical appetites. Here the worship of the appetites is brought into competition and rivalry with devotion to the one God.[121]

Our object being to trace the philosophical conceptions in mediæval Jewish literature, we cannot linger long in the study of the rest of Bahya's masterpiece, which is homiletical and practical rather than theoretic, and must content ourselves with a very brief résumé of its principal contents.

In studying the nature and attributes of God we reached the conclusion that while a knowledge of him is absolutely necessary for a proper mode of life, we cannot form an idea of him as he is in himself, and are left to such evidence as we can gather from the world of which he is the author. It becomes our duty, therefore, to study nature, as a whole and in its parts, conscientiously and minutely, in order to realize clearly the goodness and wisdom of God as exhibited therein. For various reasons we are apt to neglect this study and miss the insight and benefits arising therefrom. Chief among these hindering circumstances are our excessive occupations with the pleasures of this world, and the accidents and misfortunes to which mortal is heir, which blind him to his real good, and prevent him from seeing the blessing in disguise lurking in these very misfortunes.

But it is clear that man has a duty to study the divine goodness and wisdom as exhibited in nature, else of what use is his faculty of reason and intelligence, which raises him above the beast. If he neglects it, he places himself below the latter, which realizes all the functions of which it is capable. Bible and Talmud are equally emphatic in urging us to study the wonders of nature.

The variety of natural phenomena and the laws they exhibit give evidence of the personality of God and the existence of his will. A being without will, acting by necessity of nature, acts with unswerving uniformity.

Heaven and earth, plant and animal, all creatures great and small, bear witness, in their structure and relations, in their functions and mutual service and helpfulness, to the wisdom and goodness of God. Above all is this visible in man, the highest of earthly beings, the microcosm, the rational creature, the discoverer and inventor of arts and sciences. In the laws and statutes which were given to him for the service of God, and in the customs of other nations which take the place of our divine law, we see God's kindness to man in securing his comfort in this world and reward in the next.

Pride is the great enemy of man, because it prevents him from appreciating what he owes to God's goodness. Pride makes him feel that he deserves more than he gets, and blinds him to the truth.[122]

We all recognize the duty of gratitude to a fellow man who has done us a favor, although all such cases of benefit and service between man and man, not excepting even the kindness of a father to his child, will be found on examination to be of a selfish nature. The benefit to self may not in all cases be conscious, but it is always there. It is a father's nature to love his child as part of himself. Moreover, these human favors are not constant, and the person benefited stands comparatively on the same level of existence and worth as his benefactor. How much greater then is the duty incumbent upon us to appreciate God's favors which are not selfish, which are constant, and which are bestowed by the greatest of all beings upon the smallest of all in respect of physical strength.
