Identity and Identification
Dimitris Dimitriadis

Abstract:
In this thesis the question raised is whether, and, if so, to what degree, we
can establish identity using linguistic means, such as names, descriptions,
indexicals and demonstratives. First, we look into different ontological
considerations; after having done that, we note that taking a stand in this
discussion renders some theories of naming, descriptions and so forth,
more plausible than others.
I will argue that the Causal Theory of names is plausible and defend it 
against arguments presented by Evans. Also, the claims made by
Donellan concerning definite descriptions (referential and attributive use,
respectively) will be qualified. Indexicals and demonstratives will then
be given an account of, and the conclusion will be that we can establish
identity using descriptions and demonstratives, but not using names and
indexicals.
