As Marx says in the ‘Economic and Philosophical Manuscripts of 1844’, we realise human essence through labour (Marx, 1977:73-74). It is the realisation of human potentialities what concerns Marx in the first place, for it is the creation of our productive activity what constitutes the source of human happiness. Therefore, it is not only through labour where a person expresses its individuality, but also in the result of it; the product of labour (Marx, 1844:17-18).
