Doug Mackenzie quoted Mises:

Substitution can sometimes be useful in assessing   
meaningfulness.  E.g.,  
        It is uncontested that in the sphere of cellular   
        action organismic entities have real existence.    
        Nobody ventures to deny that individuals, brains,   
        organ systems, tissues, organs, are real factors   
        determining the course of cellular events.    
        Methodological cellularism, far from contesting the   
        significance of such collective wholes, considers it   
        as one of its main tasks to describe and to analyze   
        their becoming and their disappearing, their   
        changing structures, and their operation. And it   
        chooses the only method fitted to solve this problem   
        satisfactorily.  
  
Hmmm.  Perhaps Mises is guilty of overaggregation?
