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.

David K. Lewis on Individuation - Dictionary of Arguments

IV 58
Relation/individuation/Lewis: Relations are usually individuated through coextension. I-Relation/R-Relation/Lewis: These two relations are identical because they are coextensive.
Def R-Relation/Identity/Continuity/Person/Lewis: a certain relation and connection among person states.
Question: What conditions will survive the state in which you ask yourself this question?
For example, if you walk out of a duplicator, who will you be, who will come out of the right or left door, or both?
IV 58/59
The everyday mind, however, says something else: it asks itself whether the permanent person, which consists of the present states together with many other states, will continue to exist after the fight.
Will you be identical to someone who lives after the fight?
Seen in this light, continuity and identity do not seem to reconcile with each other.
Solution: we must not compare the formal character of the identity itself with the formal character of the relation R.
Of course, the relation is not the same as the identity.
Instead, we must compare the I relation with the R relation.
Def I-Relation/Lewis: Question: Which of the permanent persons are identical to the former?
But of course there are also I-relations between the individual states!
(>I-relations: also exist between several things (other than identity).
Proposition: each state (of a person) is I-relative and R-relative to exactly the same states. And also for all kinds of problem cases.
>Identity/Lewis, >Identification, >Identity conditions.
