“What pleased me very much was your observation in your letter: From all the plans and assumptions made by Russian intellectuals, one can conclude, with complete certainty, that socialist thought includes various currents that are fundamentally hostile to it: You will find in them mysticism, metaphysics, opportunism, reformism, and the breath of narodnism. All these currents are even more hostile because they are extremely vague and because, lacking their own organs, they cannot be expressed with sufficient clarity.”

From a letter by V. I. Lenin written in January 1913. This edition is a collection of letters that V. I. Lenin sent to the great writer and his friend M. Gorky, covering the period from 1907 to 1921. Document letters that reveal, apart from the personal relationships of the great revolutionary with the writer, many of Lenin's thoughts on the issues that occupied him throughout that historical period, during which the Great October Revolution took place and the first attempt to build socialism began.

From the content of the letters, which must be read with consideration of the specific historical moment in which they were written, issues of intra-party struggle emerge that concerned the Bolshevik Party during those years, forms of intervention by the revolutionary party, maneuvers chosen in the storm of the Revolution by Lenin himself and the Bolshevik Party, as well as philosophical issues.
