  According to the "Received View", identical quantum particles are a
previously unknown kind of objects that do not possess individual identities.
In this Chapter we analyze this view and its history, and go on to criticize
it. According to our analysis, "identical particles of the same kind, all in
the same state" should be seen as one single quantum object rather than as a
collection of many single objects. However, there are many situations in which
a single particle picture becomes applicable -- however, in such situations
identical quantum particles are distinguishable and possess their own
identities.
