My assumption that the contents of this publication will present 
little difficulty to our German workers has proven correct. At any 
rate, since March 1883, when it first appeared, three editions 
totaling 10,000 copies have been disposed of, and this under the 
operation of the now defunct Anti-Socialist Law '’—which again 
illustrates how impotent police bans against a movement like that 
of the modern proletariat are. 

Since the first edition various translations into foreign languages 
have also appeared: an Italian rendition by Pasquale Martignetti: Il 
Socialismo Utopico e il Socialismo Scientifico, Benvenuto, 1883; a 
Russian one: Razvitie naucznago socializma, Geneva, 1884; a Danish 
one: Socialismens Udvikling fra Utopi til Videnskab, in Socialistisk 
Bibliotek, Vol. 1, Copenhagen, 1885; a Spanish one: Socialismo 
utópico y Socialismo cientifico, Madrid, 1886, and a Dutch one: De 
Ontwikkeling van het Socialisme van Utopie tot Wetenschap, The 
Hague, 1886. 

The present edition has undergone various slight alterations; 
more important additions have been made in only two places: in 
the first chapter on Saint-Simon, who was dealt with too briefly in 
comparison with Fourier and Owen, and towards the end of the 
third chapter on the new form of production, the “trusts”, which 
meanwhile has become important.
