I – Marx on Social Class in Capital, Vol. III (Part VI, Ch. 52 and elsewhere)

Apart from some additional ‘supplementary remarks’ added by Engels, Marx's short discussion of the concept of social class is the final chapter of Capital, Vol. III (Part VI, Ch. 52) and is in fact incomplete. The three volumes of Capital famously end with the words, ‘Here the manuscript breaks off’, added by Engels, perhaps to give the impression that Marx was working on the manuscript of Capital to the very end and died, with pen in his hand as it were, after a lifetime of intellectual labour. The fact that this chapter was never finished is sometimes presented as a tragedy comparable to the loss of Aristotle's Comedy: if only Marx had completed this section – and surely Engels could have put some pressure on him to do so – we would know exactly what Marx's views on social class were and there would be no need to debate the matter any further. But any such argument is absurd, firstly because it represents the Marxist concept of social class as an a-historical category – as something which is fixed for all time and unchanging from one social situation to another – and this could hardly be further from Marx and Engels's actual views on this question.
