The desire to create continually is vulgar and betrays jealousy, envy, ambition. If one is something one really does not need to make anything --and one nonetheless does very much. There exists above the ''productive'' man a yet higher species.
Jealousy is both reasonable and belongs to reasonable men, while envy is base and belongs to the base, for the one makes himself get good things by jealousy, while the other does not allow his neighbour to have them through envy.
