LABRIOLA, Antonio. Essays on the Ma- 

 terialistic Conception of History. Trans- 

 lated by Charles H. Kerr. Cloth, $1.00. 



The fundamental principle of socialism, an 

 understanding of which is absolutely essential 

 to clear thinking, is the theory of historical ma- 

 terialism, or the materialistic conception of his- 

 tory. The theory is briefly outlined in the 

 introduction to the Communist Manifesto and 

 in Engels' Socialism Utopian and Scientific, 

 but it is first adequately developed in this work 

 of Labriola.

 the Abolition of Poverty. (Standard So-

 that are purposely left obscure in the official 

 documents. An arsenal of facts for socialist 

 writers and speakers.
