Individuals might be concrete or abstract, and include (among other things) physical objects, events, numbers, relations, and groups. An instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjaApwpEbGdrcN5Y29ycA" class="cyc_term">Individual</a> might have parts or structure (including discontinuous parts); but <i>no</i> individual has elements or subsets (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwGWaK5wpEbGdrcN5Y29ycA" class="cyc_term">elementOf</a> and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvZA-05wpEbGdrcN5Y29ycA" class="cyc_term">subsetOf</a>). Thus, an individual that has parts (e.g. <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVj5FpwpEbGdrcN5Y29ycA" class="cyc_term">physicalParts</a> or <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVj-BJwpEbGdrcN5Y29ycA" class="cyc_term">groupMembers</a>) is <i>not</i> the same thing as either the set or the collection containing those same parts. For example, your car is an individual, but the collection of all the parts of your car is not an individual but an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAzJwpEbGdrcN5Y29ycA" class="cyc_term">Collection</a>. This collection (unlike the car itself) is abstract: it doesn't have a location, mass, or a top speed; but it does have instances, subcollections, and supercollections. In partial contrast, the <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjmoJwpEbGdrcN5Y29ycA" class="cyc_term">Group</a> (q.v.) of parts of your car (while also not the same thing as the car itself) <i>is</i> an individual that has location and mass. Another example: A given company, the group consisting of all the company's employees, the collection of those employees, and the set of those employees are four distinct things, and only the first two are individuals. individual LouisRukeyser Louis Rukeyser LouisRukeyser Louis Rukeyser
