\textbf{Differential logic} is the component of logic whose object is the description of variation --- for example, the aspects of change, difference, distribution, and diversity --- in \htmladdnormallink{universes of discourse}{http://planetphysics.us/encyclopedia/Universe2.html} that are subject to logical description. In formal logic, differential logic treats the principles that govern the use of a \textbf{differential logical calculus}, that is, a formal system with the expressive capacity to describe change and diversity in logical universes of discourse.

A simple example of a differential logical calculus is furnished by a \htmladdnormallink{differential propositional calculus}{http://planetphysics.us/encyclopedia/DifferentialPropositionalCalculus.html}. This extends an ordinary propositional calculus in the same way that differential calculus extends analytic geometry.
