Otherwise there is only one other point lacking, which, however, Marx and I always failed to stress enough in our writings and in regard to which we are all equally guilty. As we explore the idea of Class Consciousness, let's take a short glimpse at a letter from Marx's partner, Friedrich Engels, to Franz Mehring. Responding to Mehring's polemic, The Lessing Legend, Engels uses the phrase "False Consciousness." These ideas will get developed later on by theorists like Antonio Gramsci (1891-1937; Hegemony), Louis Althusser (1918-90; the Ideological State Apparatus), and many more around the ideas of ideology, but for now, enjoy this short introduction. That is to say, we all laid, and were bound to lay, the main emphasis, in the first place, on the derivation of political, juridical and other ideological notions, and of actions arising through the medium of these notions, from basic economic facts. But in so doing we neglected the formal side — the ways and means by which these notions, etc., come about — for the sake of the content. This has given our adversaries a welcome opportunity for misunderstandings, of which Paul Barth is a striking example.
Ideology is a process accomplished by the so-called thinker consciously, indeed, but with a false consciousness. The real motives impelling him remain unknown to him, otherwise it would not be an ideological process at all. Hence he imagines false or apparent motives. Because it is a process of thought he derives both its form and its content from pure thought, either his own or that of his predecessors. He works with mere thought material which he accepts without examination as the product of thought, he does not investigate further for a more remote process independent of thought; indeed its origin seems obvious to him, because as all action is produced through the medium of thought it also appears to him to be ultimately based upon thought. The ideologist who deals with history (history is here simply meant to comprise all the spheres – political, juridical, philosophical, theological – belonging to society and not only to nature), the ideologist dealing with history then, possesses in every sphere of science material which has formed itself independently out of the thought of previous generations and has gone through an independent series of developments in the brains of these successive generations. True, external facts belonging to its own or other spheres may have exercised a co-determining influence on this development, but the tacit pre-supposition is that these facts themselves are also only the fruits of a process of thought, and so we still remain within that realm of pure thought which has successfully digested the hardest facts.
Earlier in this same letter, Engels had a self-deprecating note on his role in the partnership between Marx and himself: "If I find anything to object to it is that you attribute more credit to me than I deserve, even if I count in everything which I might possibly have found out for myself – in time – but which Marx with his more rapid coup d’oeil (grasp) and wider vision discovered much more quickly. When one has the good fortune to work for forty years with a man like Marx, one does not usually get the recognition one thinks one deserves during his lifetime. Then if the greater man dies, the lesser easily gets overrated, and this seems to me to be just my case at present."It is above all this appearance of an independent history of state constitutions, of systems of law, of ideological conceptions in every separate domain, which dazzles most people. If Luther and Calvin “overcome” the official Catholic religion, or Hegel “overcomes” Fichte and Kant, or if the constitutional Montesquieu is indirectly “overcome” by Rousseau with his “Social Contract,” each of these events remains within the sphere of theology, philosophy or political science, represents a stage in the history of these particular spheres of thought and never passes outside the sphere of thought. And since the bourgeois illusion of the eternity and the finality of capitalist production has been added as well, even the victory of the physiocrats and Adam Smith over the mercantilists is accounted as a sheer victory of thought; not as the reflection in thought of changed economic facts but as the finally achieved correct understanding of actual conditions subsisting always and everywhere – in fact if Richard Coeur-de-Lion and Philip Augustus had introduced free trade instead of getting mixed up in the crusades we should have been spared five hundred years of misery and stupidity.
This side of the matter, which I can only indicate here, we have all, I think, neglected more than it deserves. It is the old story: form is always neglected at first for content. As I say, I have done that too, and the mistake has always only struck me later.
