Personalism and Division of Labor

As has been previously proposed, 'Person' can be defined as 'particular Human', thereby signifying that a Person is a part of the Human species, not in an antagonistic relation with it.  Accordingly, Personality is one's distinctive character, and Personalism is the promotion of Personality.  So, specialization is one expression of Personality, perhaps best exemplified by a member of an orchestra.  Likewise, a Division of Labor can be conceived as Personalist.  Now, Marx's "from each according to one's ability" seems a commitment to Personalism.  On the other hand, earlier, in the German Ideology, he adamantly opposes Division of Labor, associating specialization with oppression.  So, perhaps, his appreciation for Personalism expresses maturation.
