Division of Labor, Specialization, Exclusivity

Unlike Smith, Marx does not seem to recognize the distinction between division and fragmentation, i. e. the latter as a degenerate mode of the former.  However, Marx does address a complementary problem--Division of Labor from the perspective of the individual participant, who is therein constricted to an exclusive sphere of activity, prompting from Nietzsche the image "inverse cripple".  Still, Marx himself elsewhere implicitly acknowledges a distinction between Specialization and Exclusivity, in his "From each according to his abilities" formulation, that corresponds to that between Division and Fragmentation.  There, he reflects the recognition that individual Specialization and psychological well-roundedness are not mutually exclusive, just as a Diversification of Labor can constitute collective health.
