This manuscript has a single purpose, to recognize the power that the mass contains, understood in its generic sense as resistance to change, capable of an emancipatory creative force that resists resistance to change, by partially mutating into critical mass. For this we use the dialectical reading mode that recognizes two moments, namely: the mass as potentia and the critical mass as potestas, taking up theses 2 and 3 of Dussel's Politics (2006). This movement, in turn, uses a reconstructive historical perspective that recovers for its understanding notions that go from its origin in common sense, through the appreciations of Physical Science, to the Social and Human Sciences. It is concluded that the relationship between mass and critical mass depends on its own dialectical movement as potentia-potestas according to the sense of its force, whether it is resisting change, or resisting resistance to change. This will depend on the link, the contact and the generative, social and political unifying principle of which the subjects are capable, stripping themselves of their individuality, even temporarily, reaching interests superior to themselves, only possible in the full exercise of the cultivation of qualities - virtues-, as elevation from the abstract to the concrete in the creation of other material conditions of existence, even with the risk of their corruption.
