 So understood, and returning to the four separations said to characterise alienated labour, we can see that it is the implicit claim about human nature (the fourth separation) which identifies the other three separations as dysfunctional. If one subscribed to the same formal model of alienation and self-realisation, but held a different account of the substance of human nature, very different claims about work in capitalist society might result. Imagine a theorist who held that human beings were solitary, egoistic creatures, by nature. That theorist could accept that work in capitalist society encouraged isolation and selfishness, but deny that such results were alienating, because those results would not frustrate their baseline account of what it is to be a human being (indeed, they would rather facilitate those characteristics).
