" The ingenious gentlemen who propound these Essays to the world are but a small 

 group of a vast army of men and women who are debating the same subjects. They 

 are bringing into consideration matters of which our fathers knew nothing and of 

 which earlier generations never dreamed. They are gathering together a vast mass 

 of argument, controversy and disinitation upon problems which sprang up for 

 discussion only yesterday. Yet so great has become the connection of these matters 

 with our actual life and history, so close is the relation they bear to the interests of 

 us all, that they have pervaded' all our literature and public affairs, and there are 

 to-day no political questions which are not also social questions." Albany Times.
