In this paper, I raise two objections against Van 
Inwagen's view that identity is indeterminate. Van 
Inwagen's case for this view relies mainly on the 
development of a semantics that makes invalid Evans' 
classical argument on the indeterminacy of identity. 
My objections to Van Inwagen are the following: I 
first argue that the semantics is structurally 
inadequate to fulfill the function that Van Inwagen 
sets for it and then I show that his semantics does 
not take into account certain semantic relationships.
