And a great contrast indeed does this vain, unprofitable, yet overbearing world present with such a question as that. It seems out of place to ask such a question in so magnificent, so imposing a presence, as that of the great Babylon. The world professes to supply all that we need, as if we were sent into it for the sake of being sent here, and for nothing beyond the sending. It is a great favor to have an introduction to this august world. This is to be our exposition, forsooth, of the mystery of life. Every man is doing his own will here, seeking his own pleasure, pursuing his own ends; that is why he was brought into existence. Go abroad into the streets of the populous city, contemplate the continuous outpouring there of human energy, and the countless varieties of human character, and be satisfied! The ways are thronged, carriage-way and pavement; multitudes are hurrying to and fro, each on his own errand, or are loitering about from listlessness, or from want of work, or have come forth into the public concourse, to see and to be seen, for amusement or for display, or on the excuse of business. The carriages of the wealthy mingle with the slow wains laden with provisions or merchandise, the productions of art or the demands of luxury. The streets are lined with shops, open and gay, inviting customers, and widen now and then into some spacious square or place, with lofty masses of brickwork or of stone, gleaming in the fitful sunbeam, and surrounded or fronted with what simulates a garden's foliage. Follow them in another direction, and you find the whole groundstead covered with large buildings, planted thickly up and down, the homes of the mechanical arts. The air is filled, below, with a ceaseless, importunate, monotonous din, which penetrates even to your innermost chamber, and rings in your ears even when you are not conscious of it; and overhead, with a canopy of smoke, shrouding God's day from the realms of obstinate, sullen toil. This is the end of man!
