What exactly is an individual? A flock? A herd? A breading pair? A colony? A clonal stand?
One or more members of a class, for example, the class defined as all members of a taxon.
And of course the individual that was not there - the absence!
No member is not included in one or more members, so negation needs to be treated differently (in a reasoning framework, that is; how it is recorded matters less).
