[filed under theme 7. Existence / D. Theories of Reality / 10. Vagueness / a. Problem of vagueness ]

Full Idea

Standard notions of vagueness all accept borderline cases, and presuppose a higher standpoint from which a judgement of being borderline F, rather than simply being F or being not F, can be made.

Standardly vagueness involves borderline cases, and a higher standpoint from which they can be seen

A Reaction

He says that the concept of borderline cases is an impediment to understanding vagueness. Proposing a third group when you are struggling to separate two other groups doesn't seem helpful, come to think of it. Limbo cases.


The 10 ideas from 'Vagueness: a global approach'

Classical semantics has referents for names, extensions for predicates, and T or F for sentences [Fine,K]
Local indeterminacy concerns a single object, and global indeterminacy covers a range [Fine,K]
Conjoining two indefinites by related sentences seems to produce a contradiction [Fine,K]
Identifying vagueness with ignorance is the common mistake of confusing symptoms with cause [Fine,K]
Supervaluation can give no answer to 'who is the last bald man' [Fine,K]
We identify laws with regularities because we mistakenly identify causes with their symptoms [Fine,K]
We do not have an intelligible concept of a borderline case [Fine,K]
Standardly vagueness involves borderline cases, and a higher standpoint from which they can be seen [Fine,K]
Indeterminacy is in conflict with classical logic [Fine,K]
It seems absurd that there is no identity of any kind between two objects which involve survival [Fine,K]
