|Demonstratives: E.g. this, that, that one. Problems in language use bcause of lack of clarity when referring back to prior description. - In logic missing expressibility of uniqueness. See also anaphora, deixis, relations, logical proper names, index words, indexicality, iota operator.|

Demonstratives/Brandom: are unrepeatable per se, they are made usable by the anaphora for contexts in which they then repeat themselves.
Demonstratives/Brandom: "this": must be at least implicitly connected to a sortal! The same physical gesture may indicate a book, an envelope, a color, a person, or only its external form - unrepeatable per se.
Demonstratives/Brandom: you cannot describe a coherent language in which expressions are used demonstratively, but not pronominally. (it is possible vice versa) - various Tokenings of this, here, or now are generally no recurrences of each other, or even co-identifiable, but only as a repeatable element, i.e. as elements of recurrence classes, they are substitutable.
Demonstratives/Possible World/Kaplan: introduces the rigidizing operator "tthis" and determines that tthis (!xDx) is to be rigid - it picks out from every world what it really refers to in the real world, while !xDx is not a rigid designator in general, because its denotation varies from world to world - (same function as "precisely this cat") - Names/Kyplean: can be understood as rigidized (tthisissed) descriptions and demonstratives.

Demonstratives/Possible World/Brandom: demonstrative Tokenings can only recur anaphorically and thus rigidly.
This/Demonstratives/Brandom: not really directly referential, but require implicit sortals.
