 Magnitudes are normally taken as being extensive quantities, like mass or volume, which are defined over extended regions of space. By contrast, infinitesimal magnitudes have been construed as intensive magnitudes resembling locally defined intensive quantities such as temperature or density. The effect of “distributing” or “integrating” an intensive quantity over such an intensive magnitude is to convert the former into an infinitesimal extensive quantity: thus temperature is transformed into infinitesimal heat and density into infinitesimal mass. When the continuum is the trace of a motion, the associated infinitesimal/intensive magnitudes have been identified as potential magnitudes—entities which, while not possessing true magnitude themselves, possess a tendency to generate magnitude through motion, so manifesting “becoming” as opposed to “being”.
