"Professor Graham presents an outline of the successive schemes of three writers who have chiefly influenced the development of socialism, and dwells at length upon the system of Rousseau, that of St. Simon, and on that of Karl Marx, the founder of the new socialism, 'which has gained favor with the working classes in all civilized countries,' which agrees with Rousseau's plan in being democratic, and with St. Simon's in aiming at collective ownership.... The professor is an independent thinker, whose endeavor to be clear has resulted in the statement of definite conclusions. The book is a remarkably fair digest of the subject under consideration."_--Philadelphia Ledger._ ==Dynamic Sociology:== _Or, Applied Social Science, as based upon Statical Sociology and the less Complex Sciences._ By LESTER F. WARD, A.M. In 2 vols. 12mo. Cloth, $4.00. "A book that will amply repay perusal.... Recognizing the danger in which sociology is, of falling into the class of dead sciences or polite amusements, Mr. Ward has undertaken to 'point out a method by which the breath of life can be breathed into its nostrils.'"--_Rochester Post-Express._ "Mr. Ward has evidently put great labor and thought into his two volumes, and has produced a work of interest and importance. He does not limit his effort to a contribution to the science of sociology.... He believes that sociology has already reached the point at which it can be and ought to be applied, treated as an art, and he urges that 'the State' or Government now has a new, legitimate, and peculiar field for the exercise of intelligence to promote the welfare of men."--_New York Times._ ==Criminal Sociology.== By Prof. E. FERRI. A new volume in the Criminology Series, edited by W. Douglas Morrison, 12mo. Cloth, $1.50. In this volume Professor Ferri, a distinguished member of the Italian Parliament, deals with the conditions which produce the criminal population, and with the methods by which this anti-social section of the community may be diminished. He divides the causes of crime into two great classes, individual and social. The individual causes consist of physical and mental defects; the social causes consist of social disadvantages of every description. His view is that the true remedy against crime is to remove individual defects and social disadvantages where it is possible to remove them. He shows that punishment has comparatively little effect in this direction, and is apt to divert attention from the true remedy--the individual and social amelioration of the population as a whole.
