To make these “means of production the property of society” is then the problem of Ward’s applied sociology and Dietzgen’s social democracy alike. According to both, this emancipation of the mass of the people from the last form of slavery is the one consuming task of civilization. And the psychic factor, the consciously reasoning brain of man is, according to both, to be more than ever the instrument of “achievement.” To Dietzgen especially, the time is rotten-ripe for the great change. “The salvation of humanity is involved in this question. It is so great and sublime that all other problems which time may bear in its folds must wait in silence. The whole of old Europe is waiting with bated breath the fulfilling of the things which are coming. “Oh, ye short-sighted and narrow-minded, who can not give up the fad of moderate, slow, organic progress! Do you not perceive that all your great liberal passions sink to the level of mere trifling, because the great question of social salvation is on the order of the day? The calm precedes the tempest. History stands still, because she gathers force for a great catastrophe.” THE LEWIS LECTURES. This book, =Evolution, Social and Organic=, is the first volume of a series of lectures to which we expect to make notable additions in the future. We can at this time definitely promise two volumes, which will be made up from the lectures delivered by Mr. Lewis at the Garrick Theater during the winter and spring of 1908. =Ten Blind Leaders of the Blind.= This will in all probability be the second volume of the Lewis Lectures, and we expect to publish it in May or June. It will consist of critical studies of the theories of such reformers, philosophers and moralists as Benjamin Kidd, Henry George, Dr. Schaeffle, Thomas Carlyle, Auguste Comte and Immanuel Kant. It must not be imagined that Mr. Lewis in these lectures is merely attempting to refute these thinkers, nor that he would disparage the service that each in his time has rendered. On the contrary his aim is to give the reader as clear a comprehension as possible of what each of these men has achieved. And he furthermore shows how the outlook of each was limited by the economic environment from which flowed the mental atmosphere in which he lived, so that it would have been unreasonable for us to expect from these writers any other conclusions than those at which they actually arrived. Understanding these conditions we can better understand how to meet the arguments of those still influenced by the outgrown ideas which are perhaps best stated in the writings of the leaders here considered.
