2. As a fundamental formula for all material happenings, analogous to the "world-formula" of Laplace, J G. Vogt proposes the following (Polit. Anthrop. Rev., Leipzig, 1907-8, VI., 573): If Pe represent the positive or dissipation potential (emissives Potential) and Pr the negative or concentrational potential (rezeptives Potential) of any given set of forces, then ${\displaystyle Pe+Pr=0}$ or ${\displaystyle \int _{n}d\ Pe+\int _{o}^{n}d\ Pr=0}$. This is, however, only another restatement of Newton's Third Law of Motion, that action and reaction are equal and in opposite directions.
