Two essays by Daniel Guerin, written in 1969, beginning with the impact that the Paris Commune and Bakunin's critiques of Marxism had on the ideas of Marx with particular emphasis on Marx's 1871 address to the General Council of the International, 'The Civil War In France', which many anarchists consider to be Marx's "most anarchist" statement and in general a validation of anarchist thought. Guerin concludes the text with a proposal for a synthesis of Marxism and Anarchism which Guerin refers to as "Libertarian Marxism".
