&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;lt;font size=&amp;quot;3&amp;quot;&amp;gt;&amp;amp;#9758;&amp;lt;/font&amp;gt; This page belongs to resource collections on [[Logic Live|Logic]] and [[Inquiry Live|Inquiry]].&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Differential logic&amp;#039;&amp;#039;&amp;#039; is the component of logic whose object is the successful description of variation &amp;amp;mdash; for example, the aspects of change, difference, distribution, and diversity &amp;amp;mdash; in [[universes of discourse]] that are subject to logical description.  In formal logic, differential logic treats the principles that govern the use of a &amp;#039;&amp;#039;differential logical calculus&amp;#039;&amp;#039;, that is, a formal system with the expressive capacity to describe change and diversity in logical universes of discourse.&lt;br /&gt;
&lt;br /&gt;
A simple example of a differential logical calculus is furnished by a [[differential propositional calculus]].  This augments ordinary [[propositional calculus]] in the same way that the [[differential calculus]] of [[Leibniz]] and [[Newton]] augments the [[analytic geometry]] of [[Descartes]].&lt;br /&gt;
