THE DUC DE LA ROUCHEFOUCAULD's celebrated "Moral Reflections, Sentences, and Maxims," have just appeared in a new and very much improved translation, and with notes, pointing out similarities of sentiments in ancient and modern authors, and sometimes proving that Rochefoucauld's good things have been made use of without sufficient acknowledgment, by moderns. There is also an introduction, which dissertates well on the purpose and quality of the reflections. Such books were once very popular; but in this country they have not been much read. We have indeed had numerous editions of "Lacon," and Dr. Bettner's "Acton" has found a thousand purchasers; but the Rev. Dr. Hooker's "Maxims," which, in our opinion, are as good as anything of their kind in the English language, we believe have not attracted attention, and Mr. Simms's "Egeria" has been printed only in the columns of a newspaper. * * * * * A new theory has just been propounded at Paris in a book called "Armanase," (a Sanscrit word, meaning the "Reign of Capacity"). The author asserts the present forms of administrative government are injurious instead of useful to society, and ought to be replaced by institutions of a new and different order. His principle is, that the sovereignty of the individual ought to be instituted for that of governments, and that great associations of mutual assurance may be advantageously substituted for the existing system of management by office-holders. The author shows also that the progress of the natural and mechanical sciences will deliver man from the pressure of the more painful sorts of labor; and that wealth, freed from the barriers which now hinder its circulation, would be distributed freely throughout society. Intellectual property would be seriously guaranteed, and would enrich the men of genius, whose inventions and discoveries are now profitable, not to the authors, but to the capitalists who take advantage of them. By this means an important element of revolutions will be removed. The author proposes, that in order to prevent all suffering, a civil list shall be set apart for the people, who will be the king. This civil list is to be composed of a tax of one per cent., levied on all who have property in favor of those who have nothing. But, says he, let no one imagine that all would be dissolution and ruin in this system, without law or government. Crimes and offenses will be tried by juries, that is to say, by a living code. Property will no longer be seizable for debt, and the courts will become useless. Everybody shall have the absolute right to buy land by paying its possessor ten per cent, on its value: this is to give a chance for carrying on all sorts of grand public enterprises without trouble from the proprietors of little pieces of land. It may perhaps be doubted, whether the "Reign of Capacity" has exhibited any astonishing endowments in that respect. * * * * *
