Time Representation

A point of view arising from fundamental physical considerations makes the concept of Process more fundamental than the concept of Time, since references to a time parameter are simply references to a process taken as standard, in other words, a clock.

We can always develop another “naive physics”, natural language “tense logic”, or implicit psychological theory of time, and maybe that’s all we need in particular settings, but if we push for a deeper logical analysis of timed processes themselves then we need a logical framework capable of dealing with relations between systems which undergo changes in their properties, as described by logical statements.

That is the impulse motivating Differential Logic.  As it turns out, Peirce’s way of doing logic, especially in graphical form, is naturally adapted to dealing with change and difference in logical form.
