Selected Letters Marx-Engels

The importance of these letters in Lenins words: Not only do Marx and Engels stand out before the reader in clear relief in all their greatness but the extremely rich theoretical content of Marxism is unfolded in a highly graphic way because in the letters Marx and Engels return again and again to the most diverse aspects of their teaching emphasising and explaining —at times discussing and persuading each other—what is newest (in relation to earlier views) most important and most difficult. There unfolds before the reader a strikingly vivid picture of the history of the working-class movement all over the world—at its most important junctures and in its most essential points. Even more valuable is the history of the politics of the working class.
