I have outlived three generations of brave men, mistaken as they may have been, to whom I was deeply attached, and whose memory remains dear to me. And here again, I have discovered that it is nearly impossible to live a life devoted wholly to a cause which one believes to be just—a life, that is, where one refuses to separate thought from daily action. The young French and Belgian rebels of my twenties have all perished; my syndicalist comrades of Barcelona in 1917 were nearly all massacred; my comrades and friends of the Russian Revolution are probably all dead—any exceptions are only by a miracle. A ll were brave, all sought a principle of life more noble and more just than that of surrender to the bourgeois order, and except perhaps for certain young men, disillusioned and crushed before their consciousness had crystallized, all were engaged in movements for progress. I must confess that the feeling of having so many dead men at my back, many of them my betters in energy, talent, and historical character, has often overwhelmed me, and that this feeling has been for me the source of a certain courage, if that is the right word for it.
