NaturalThing The notoriously hard to define collection of "natural" things. An individual is an instance of this collection if it is itself an individual or <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvYjIS5wpEbGdrcN5Y29ycA" class="cyc_term">Situation</a> that occurs in nature, i.e., not as a result of an <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVinb5wpEbGdrcN5Y29ycA" class="cyc_term">IntelligentAgent</a>'s (or group thereof) intentions to modify the environment, or else is an individual that is the <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWStbZwpEbGdrcN5Y29ycA" class="cyc_term">outputsCreated</a> of an <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViADZwpEbGdrcN5Y29ycA" class="cyc_term">Event</a> that is itself natural. natural thing A collection of collections, and a specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjk05wpEbGdrcN5Y29ycA" class="cyc_term">RegionType</a>.

For example, the collection <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViKmJwpEbGdrcN5Y29ycA" class="cyc_term">State_UnitedStates</a> is an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjlE5wpEbGdrcN5Y29ycA" class="cyc_term">SpatiallyDisjointRegionType</a>, since the territories of U.S. states do not overlap.

Moreover, each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWXYgJwpEbGdrcN5Y29ycA" class="cyc_term">ExistingObjectType</a> is a collection that is temporally stuff-like (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVitN5wpEbGdrcN5Y29ycA" class="cyc_term">TemporalStuffType</a>) but physically-spatially object-like (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVirnZwpEbGdrcN5Y29ycA" class="cyc_term">ObjectType</a>) -- i.e. object-like with respect to some physical-spatial part-whole predicate (e.g. some specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4r8a2smPXcQdiEoJhcx65EiQ" class="cyc_term">properPhysicalDecompositions</a>).

Abductive inferences sometimes involve hypothesizing the existence of entities as part of the explanation of some assertion or set of assertions.

Roughly, abductive inferences consume conceptual / theoretical knowledge rather than produce it.
