To be able to live a life of this character is to achieve 'self-activity' (actualisation), which Marx believes will only become possible after communism has replaced capitalism. 'Only at this stage does self-activity coincide with material life, which corresponds to the development of individuals into complete individuals and the casting-off of all natural limitations. The transformation of labour into self-activity corresponds to the transformation of the earlier limited intercourse into the intercourse of individuals as such' .
