Heine and Börne. Lassalle indeed had drunk deeper than most of the revolutionists of '48. He was not only a democrat and a republican; he was also a socialist. Even before his first visit to Paris he had become acquainted with the writings of St. Simon, Fourier, and the Utopian socialists in general.

The nature of Lassalle's social ideal and the character of the means by which he sought to justify it are for the
