 A second concern is the role of human nature in the interpretation of alienation offered here. In one exegetical variant of this worry, the suggestion is that this account of alienation rests on a model of universal human nature which Marx’s (later) understanding of historical specificity and change prevents him from endorsing. However, there is much evidence against this purported later rejection of human nature (see Geras 1983). Indeed, the “mature” Marx explicitly affirms that human nature has both constant and mutable elements; that human beings are characterised by universal qualities, constant across history and culture, and variable qualities, reflecting historical and cultural diversity (McMurtry 1978: 19–53). One systematic, rather than exegetical, variant of the present worry suggests that we should not endorse accounts of alienation which depend on “thick” and inevitably controversial accounts of human nature (Jaeggi 2016). Whatever view we take of that claim about our endorsement, there seems little doubt about the “thickness” of Marx’s own account of human flourishing. To provide for the latter, a society must satisfy not only basic needs (for sustenance, warmth and shelter, certain climatic conditions, physical exercise, basic hygiene, procreation and sexual activity), but also less basic needs, both those that are not always appreciated to be part of his account (for recreation, culture, intellectual stimulation, artistic expression, emotional satisfaction, and aesthetic pleasure), and those that Marx is more often associated with (for fulfilling work and meaningful community) (Leopold 2007: 227–245).
