 Rigidity is applied commonly to indexicals, like ‘now’ or ‘you’, as well as names. If, when I use ‘you’ in a context, my utterance means something like the person at the door (Nunberg 1993; Smith 1989 §5), then presumably it is not rigid. You may be at the door, but in another possible world it is another philosopher who comes visiting. On the other hand, if (as Kaplan proposes: 1989a) ‘you’ refers directly to an individual, without amounting to a disguised description meaning the same as a description like ‘the person at the door’, then it would seem to be rigid. So if I say, pleasantly surprised, “You made good time,” we could discuss reasons for this and conditions under which this might not have been the case, but in all of our considerations the same individual, and not anyone else who might have been at my door in good time or not, is the one in question. The individual in question is the one who is in fact identical to you (as any account could put it). After Kaplan, indexicals have typically been treated as rigid; but there seem to be nonrigid uses.
