seperation between art and life

This holds doubly: for this contradictory labour which has not yet created the subjective and objective conditions for itself (or also, in contrast to the pastoral etc. state, which it has lost), in which labour becomes attractive work, the individual's self-realization, which in no way means that it becomes mere fun, mere amusement, as Fourier, with grisette-like naivete, conceives it. Really free working, the composing of music for example, is at the same time damned seriousness and demands the greatest of effort. The work of material production can achieve this character only (1) when its social character is posited, (2) when it is of a scientific and at the same time general work, i.e. if it ceases to be merely human exertion as a specifically harnessed natural force, but exertion as subject, which appears in the production process not in a merely natural, spontaneous form, but as an activity regulating all the forces of nature.
