I think people should read this from Marx and Engels:
>Once man is recognised as the essence, the basis of all human activity and situations, only “Criticism” can invent new categories and transform man himself into a category and into the principle of a whole series of categories, as it is doing now. It is true that in so doing it takes the only road to salvation that has remained for frightened and persecuted theological inhumanity. History does nothing, it “possesses no immense wealth”, it “wages no battles”. It is man, real, living man who does all that, who possesses and fights; “history” is not, as it were, a person apart, using man as a means to achieve its own aims; history is nothing but the activity of man pursuing his aims.
