“And so it will be with some second Noah, whose happier lot it shall be to see knowledge cover the earth, bearing on its bosom all that is worthy of the new heavens and new earth; while all that is unworthy of them is sunk and lost. By the agency of his gigantic servants he may be raised to that pinnacle of the universe whence he may choose to look forth again, and see what new services are appointed to man, and who are the guides and guardians allotted to his higher state.” "And what will he behold?——But it is foolish to inquire. One must be there to know." "To know fully. But though we can but barely speculate upon what he will see, we may decidedly pronounce upon what he will not see. We cannot tell how many galaxies will be perceived to complete the circle of Nature’s crown, nor what echoes of her diapason shall be wafted to the intent spirit. We cannot tell how near he may be permitted to approach to behold the evolution of a truth from apparent nothingness, as we are apt to fancy a seraph watches the creation of one of yonder worlds—first distinguishing the dim apparition of an orb emerging from the vacuum, then seeing it moulded into order, and animated with warmth, and invested with light, till myriads of adorers are attracted to behold it sent forth by the hand of silence on its everlasting way. We cannot tell to what depth man may then safely plunge, to repose in the sea-caves, and listen to the new tale that its thunders interpret, and collect around him the tributaries of knowledge that come thronging down the green vistas of ocean light. We cannot tell what way will be opened before him to the dim chambers of the earth, where Patience presides, while her slow and blind agents work in dumb concert from age to age, till, the hour being come, the spirit of the volcano, or the angel of the deluge, arrives to burst their prison-house. Of all these things we can yet have but a faint conception; but of some things which will not be we can speak with certainty." “That when these inanimate powers are found to be our best servants, the immortal mind of man will be released from the drudgery which may be better performed by them. Then, never more will the precious term of human life be spent in a single manual operation; never more will the elastic limbs of children grow rigid under one uniform and excessive exercise; never more will the spirit sit, self-gnawing, in the fetters to which it has been condemned by the tyranny of ignorance, which must have its gratifications. Then bellows may breathe in the tainted streams of our factories, and human lungs be spared, and men’s dwellings be filled with luxuries, and no husbandman be reduced from his sovereignty of reason to a similitude with the cattle of his pastures. But much labour has already been set free by the employment of the agency of nature; and how little has been given to science!”
