“It was at about this time [1925] that I read Capital and German Ideology. I found everything perfectly clear, and I really understood absolutely nothing. To understand is to change, to go beyond oneself. This reading did not change me. By contrast, what did begin to change me was the reality of Marxism, the heavy presence on my horizon of the masses of workers, an enormous, sombre body which lived Marxism, which practiced it, and which at a distance exercised an irresistible attraction on petit bourgeois intellectuals. When we read this philosophy in books, it enjoyed no privilege in our eyes. A priest, who has just written a voluminous and very interesting work on Marx, calmly states in the opening pages: “It is possible to study [his] thought just as securely as one studies that of any other philosopher or any other sociologist.” That was exactly what we believed. So long as this thought appeared to us through written words, we remained “objective.” We said to ourselves: “Here are the conceptions of a German intellectual who lived in London in the middle of the last century.” But when it was presented as a real determination of the Proletariat and as the profound meaning of its acts – for itself and in itself – then Marxism attracted us irresistibly without our knowing it, and it put all our acquired culture out of shape. I repeat, it was not the idea which unsettled us; nor was it the condition of the worker, which we knew abstractly but which we had not experienced. No, it was the two joined together. It was – as we would have said then in our idealist jargon even as we were breaking with idealism – the Proletariat as the incarnation and vehicle of an idea. And I believe that we must here complete Marx's statement: When the rising class becomes conscious of itself, this self consciousness acts at a distance upon intellectuals and makes the ideas in their heads disintegrate... This Proletariat, far off, invisible, inaccessible, but conscious and acting, furnished the proof – obscurely for most of us – that not all conflicts had been resolved. We had been brought up in bourgeois humanism, and this optimistic humanism was shattered when we vaguely perceived around our town the immense crowd of “sub-men conscious of their subhumanity.”
