Note 71 — Chapter III · CONCERNING THE INTERPRETATION AND CRITICISM OF SOME CONCEPTS OF MARXISMToC

See, in particular, Marx's ideas: Ueber Feuerbach, in 1845, in the appendix to Engels' book, Ludwig Feuerbach und der Ausgang der Klassischen deutschen Philosophie, 2nd ed. Stuttgart, 1895, pp. 59-62; and cf. Andler in Revue de metaphysique, 1897, Labriola, o.c. passim and Gentile, l.c., p. 319. From this point of view (i.e. limiting the statement to the theory of knowledge) we might speak like Labriola of historical materialism as a philosophy of practice, i.e. as a particular way of conceiving and solving, or rather of over-coming, the problem of thought and of existence. The philosophy of practice has now been designedly studied by Gentile in the volume referred to.
