There is no need whatever, in explaining the unity of the German Socialist Party and the dismembered state of the French Socialist Party, to search for the special features in the history of the respective countries, to compare the conditions of military semi absolutism in the one country with republican parliamentarism in the other, or to analyze the effects of the Paris Commune and the effects of the Anti Socialist in Germany; to compare the economic life and economic development of the two countries, or recall that 'the unexampled growth of German Social Democracy' was accompanied by a strenuous struggle, unexampled in the history of socialism, not only against mistaken theories (M hlberger, hring, the Socialists of the Chair), but also against mistaken tactics (Lassalle), etc., etc.
