Marx's non-speciesist concept of labour

Human-animal scholars have repeatedly accused Marx of standing in the tradition of a Cartesian human-animal dualism. One central piece of evidence brought forward to substantiate the attack is Marx's concept of labour. The present article, however, argues that Marx's conceptualisation of labour is actually non-speciesist and recognises non-waged and other than human forms of labour as well without renouncing qualitative distinctions between them. For Marx, both useful labour and the historically specific capitalist form of social labour cannot be reduced to something peculiar to man. Useful labour encompasses a wide range of ways to transform nature. Due to the bourgeois social relations, capitalist social labour is instead limited to human productive wage labour, excluding numerous types of human labour as well as animal labour. Thus, his concept of labour proves that Marx is not just another 'speciesist' scholar in the long Western tradition of philosophy.
