Antonio Labriola in the crisis of Marxism. The article deals with the relationship between Marxism and science in Antonio Labriola’s philosophy in the years 1898-1899. In the first part, the Author looks at the content of the Postscript to Discorrendo di socialismo e di filosofia and critically analyzes Labriola’s objections to some of the central theses defended by Benedetto Croce on the theory of value and the economics of Karl Marx. In the second part, two important writings by Labriola linked to the incipient debate on revisionism are examined: Polemiche sul socialismo and Sulla crisi del marxismo. In conclusion, the Author identifies in a specific conception of theory defended by Labriola the common trait between these two apparently distinct areas of inquiry.
Keywords: Antonio Labriola, Benedetto Croce, revisionism, critique of political economy, theory.
