Religion and poetry are all the civilization of the Arab. “The ground of Paradise,” said Mohammed, “is extensive, and the plants of it are hallelujahs.” Religion and poetry: the religion teaches an inexorable destiny; it distinguishes only two days in each man’s history, the day of his lot, and the day of judgment. The religion runs into asceticism and fate. The costume, the articles in which wealth is displayed, are in the same extremes. Thus the diamond and the pearl, which are only accidental and secondary in their use and value to us, are proper to the oriental world. The diver dives a beggar and rises with the price of a kingdom in his hand. A bag of sequins, a jewel, a balsam, a single horse, constitute an estate in countries where insecure institutions make every one desirous of concealable and convertible property. Shall I say, further, that the orientals excel in costly arts, in the cutting of precious stones, in working in gold, in weaving on hand-looms costly stuffs from silk and wool, in spices, in dyes and drugs, henna, otto and camphor, and in the training of slaves, elephants and camels,--things which are the poetry and superlative of commerce. On the other hand,--and it is a good illustration of the difference of genius,--the European nations, and, in general, all nations in proportion to their civilization, understand the manufacture of iron. One of the meters of the height to which any civility rose is the skill in the fabric of iron. Universally, the better gold, the worse man. The political economist defies us to show any gold-mine country that is traversed by good roads: or a shore where pearls are found on which good schools are erected. The European civility, or that of the positive degree, is established by coal-mines, by ventilation, by irrigation and every skill--in having water cheap and pure, by iron, by agriculture for bread-stuffs, and manufacture of coarse and family cloths. Our modern improvements have been in the invention of friction matches; of India-rubber shoes; of the famous two parallel bars of iron; then of the air-chamber of Watt, and of the judicious tubing of the engine, by Stephenson, in order to the construction of locomotives. Meantime, Nature, who loves crosses and mixtures, makes these two tendencies necessary each to the other, and delights to re-enforce each peculiarity by imparting the other. The Northern genius finds itself singularly refreshed and stimulated by the breadth and luxuriance of Eastern imagery and modes of thinking, which go to check the pedantry of our inventions and the excess of our detail. There is no writing which has more electric power to unbind and animate the torpid intellect than the bold Eastern muse.
