|Individuation, philosophy: the picking out of an object by a determination by means of additional information which is not to be derived from a single statement which contains this object. For example, beliefs are individualized by content, not e.g. by the length of the character strings with which they are expressed. The contents of a belief are, in turn, not individuated by their repetition, but by other contents.|

Individuation/Ontology/Simons: mere hyphenated words shall not create a new ontology, because they can not be individuated without the parts.
Individuation/Mereology/Simon: for it mereological terms are important. E.g. to see what Fido is, we must be able to decide what is a part of it at a certain time, which overlaps with it and what is separated from it. - Problem: Fido itself is not mereologically constant. - Solution: we must know the limits within which metabolism is permitted. - type: does not specify which particular parts the thing has, but what type of parts it normally does have - and what relations these usually relate to each other.
