When Dr. Eugene Duehring，privat docent at Ber-lin University, in r875，proclaimed the fact that he hadbecome converted to Socialism，he was not content totake the socialist movement as he found it, but set outforthwith to promulgate a theory of his own.His wasa most elaborate and self-conscious mission.He stoodforth as the propagandist not only of certain specific andpeculiar views of socialism but as the originator of a newphilosophy,and the propounder of strange and wonder-ful theories with regard to the universe in general.Thetaunt as to his all-comprehensiveness of intellect，withwhich Engels pursues him somewhat too closely andmuch too bitterly, could not have affected Herr Duehringvery greatly.He had his own convictions with respectto that comprehensive intellect of his and few will befound to deny that he had the courage of his convic-tions.

Thirty years have gone since Duehring published thefact of his conversion to socialism.The word“" con-version ”contains in itself the distinction between thesocialism of thirty years ago and that of to-day.Whatwas then a peculiar creed has now become a very wide-spread notion.Men are not now individuaily converted to socialism but whole groups and classes are driven intothe socialist ranks by the pressure of circumstances.The movement springs up continually in new and unex-pected placcs.Here it may languish apparently，thereit gives every indication of strong，new and vigorouslife.
