The new arrangement of state life, which was partly established, partly introduced, by Solomon, the leisure of peace, the close contact with Phoenicia and Egypt, the entrance of Israel into extensive trade, the increase of prosperity, the richer, more various, and more complicated conditions of life, the wider range of vision, could not be without their influence on the intellectual life of the Israelites. From this time an increased activity is displayed. They were impelled and forced to observation, comparison and consideration in quite another manner than before. The results of these new reflections grew into fixed rules, into proverbs and apophthegms. In this intellectual movement Solomon took a leading part. A man of poetical gifts like his father, he composed religious and other poems (1005 in number, according to the tradition). The impulse to knowledge and the sense of art which he excites must first have found room within himself; his vision, like his means, reached the furthest. Hence we have no reason to doubt that he was one of the wisest in his nation. "God," says the Book of Kings, "gave Solomon a spirit beyond measure, as the sand of the sea. And the wisdom of Solomon was greater than the wisdom of all the sons of the East, and the wisdom of Egypt. He was wiser than all men, and he spoke of the trees, from the cedar on Lebanon to the hyssop which grows on the wall, and of the cattle and the birds, and the worms and the fishes."[360] Beside poetry and extensive knowledge of nature, in which he surpassed his wisest countrymen, Ethal and Heman, Chalcol and Darda, it was his keen observation, his penetrating knowledge of mankind, his experience of life which made the greatest impression. His proverbs and rules of life seemed to the Israelites so pointed and exhaustive that they attributed to Solomon the entire treasure of their gnomic wisdom, which was afterwards collected into one body. Among these proverbs scarcely any can with complete certainty be ascribed to Solomon, but the fact that all are attributed to him is a sufficient proof that Solomon possessed a very striking power in keen observation of human nature and human affairs, in the pregnant expression of practical experience, in combining its lessons into pointed and vigorous sentences.
