Conservative, or Bourgeois, Socialism
A part of the bourgeois is desirous of redressing social grievances, in order to secure the continued existence of bourgeois society. To this section belong to economists, philantropists, humanitarians, improvers of the condition of the working class, organisers of charity, members of societies for the prevention of cruelty to animals, temperance fanatics, hole-and-corner reformers of every imaginable kind. This form of socialism has, however, been worked out into complete systems.
The socialist bourgeois want all the advantages of modern social conditions without struggles and dangers necessarily resulting therefrom. They desire the existing state of society minus its revolutionary and disintegrating elements. They wish for a bourgoisie without a proletariat. The bourgoisie naturally conceives the world in which it is supreme to be the best; and bourgeois Sicalism develops this comfortable conception into various more or less complete systems. In requiring the proletariat to carry out such a system, and thereby to march straightway into the social New Jerusalem, it but requires in reality, that the proletariat should remain within the bounds of existing society, but should cast away all its hateful ideas concerning the bourgeoisie.
