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

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._

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
