author a _penchant_ for the marvellous, provided that the marvellous is in no way connected with revelation. "A brilliant French writer has suggested that even if the natural course of evolution does of itself necessitate the final destruction of the world, yet our race, judging from the magnificent achievements of science and art already reached, may, within ten thousand centuries, which will be long before the foreseen end approaches, obtain such a knowledge and control of the forces of nature as to make collective humanity master of this planet, able to shape and guide its destinies, ward off every fatal crisis, and perfect and immortalize the system as now sustained. It is an audacious fancy. But, like many other incredible conceptions which have forerun their own still more incredible fulfilment, the very thought electrifies us with hope and courage." (P. 18.) This is indeed brilliant! It surpasses the famous moon-hoax of Mr. Locke, and the balloon-voyages of that wild genius Edgar A. Poe, from whom we have some recent and interesting intelligence, contained in a volume which we recommend to the congregation of Music Hall; the volume being entitled _Strange Visitors, by a Clairvoyant_. In those days, probably, our Congress will have a committee on comets, and make appropriations for a railroad to the Dog-star. The second objection to Mr. Alger's argument runs partly into the first. It is, we have said, totally wanting in scientific method and accuracy. This is true of the entire process by which the thesis of the discourses is sustained. This thesis is, that the present constitution of the world and the human race will endure for ever, or at least for an indefinitely long period. If there were no light to be had on this point except the light of nature, the opinion maintained by the author would be at best only a conjecture. It could not be made even solidly probable, unless some rational theory were first established concerning the ultimate destiny of the human race, and the end for which the present miserably imperfect constitution of the world had been decreed by the Creator, and the perpetuity of the existing order on the earth were shown to have a reason in this final cause of man's creation. The author has not done this, and we do not believe that it is possible to do it, even prescinding all question of revelation. Even on scientific grounds--that is, reasoning from all the analogies known to us, and from purely rational and philosophical data--it is far more probable and reasonable to suppose that the present state of the world is merely preparatory to a far higher and more perfect state, and will be swept away to make place for it. But when we consider the universality and antiquity of this latter belief, and the solid mountain of historical, miraculous, and moral evidence on which rests the demonstration that this belief proceeds from a divine revelation, it is the most unscientific
