Objects such as a cloud or Mount Everest seem to have fuzzy boundaries in nature [Keefe/Smith]
|
7. Existence / D. Theories of Reality / 10. Vagueness / c. Vagueness as ignorance
9044
|
If someone is borderline tall, no further information is likely to resolve the question [Keefe/Smith]
|
9048
|
The simplest approach, that vagueness is just ignorance, retains classical logic and semantics [Keefe/Smith]
|
9055
|
The epistemic view of vagueness must explain why we don't know the predicate boundary [Keefe/Smith]
|
7. Existence / D. Theories of Reality / 10. Vagueness / f. Supervaluation for vagueness
9049
|
Supervaluationism keeps true-or-false where precision can be produced, but not otherwise [Keefe/Smith]
|
9056
|
Vague statements lack truth value if attempts to make them precise fail [Keefe/Smith]
|
9058
|
Some of the principles of classical logic still fail with supervaluationism [Keefe/Smith]
|

9061
|

|
9062
