most important books of the nineteenth century because of its power of changing the minds of those who read it, in spite of its unsound capitalist economics, its parade of quotations from books which the author had either not read or not understood, its affectation of algebraic formulas, and its general attempt to disguise a masterpiece of propagandist journalism and prophetic invective as a drily scientific treatise of the sort that used to impose on people in 1860, when any book that pretended to be scientific was accepted as a Bible. In those days Darwin and Helmholtz were the real fathers of the Church; and nobody would listen to religion, poetry or rhetoric; so that even Socialism had to call itself "scientific," and predict the date of the revolution, as if it were a comet, by calculations founded on "historic laws." To my amazement these reasonable remarks were received as hideous blasphemies; none of the party papers were allowed to print any word of mine; the very Revisionists themselves found that the scandal of my heresy damaged them more than my support aided them; and I found myself an outcast from German Social-Democracy at the moment when, thanks to Trebitsch, the German bourgeoisie and nobility began to smile on me, seduced by the pleasure of playing with fire, and perhaps by Agnes Sorma's acting as Candida. Thus you may see that when a German, by becoming a Social-Democrat, throws off all the bonds of convention, and stands free from all allegiance to established religion, law, order, patriotism, and learning, he promptly uses his freedom to put on a headier set of chains; expels anti-militarists with the blood-thirstiest martial anti-foreign ardor; and gives the Kaiser reason to thank heaven that he was born in the comparative freedom and Laodicean tolerance of Kingship, and not in the Calvinistic bigotry and pedantry of Marxism.
