Single Idea 8944

[filed under theme 9. Objects / B. Unity of Objects / 3. Unity Problems / e. Vague objects ]

Full Idea

Vague terms come in at least two different kinds: those whose constituent parts come in discrete packets (bald, rich, red) and those that don't (beauty, boredom, niceness).

Gist of Idea

Vagueness can involve components (like baldness), or not (like boredom)

A Reaction

The first group seem to be features of the external world, and the second all occur in the mind. Baldness may be vague, but presumably hairs are (on the whole) not. Nature doesn't care whether someone is actually 'bald' or not.


The 10 ideas from Jennifer Fisher

We could make our intuitions about heaps precise with a million-valued logic [Fisher]
We can't explain 'possibility' in terms of 'possible' worlds [Fisher]
Three-valued logic says excluded middle and non-contradition are not tautologies [Fisher]
Fuzzy logic has many truth values, ranging in fractions from 0 to 1 [Fisher]
Vagueness can involve components (like baldness), or not (like boredom) [Fisher]
If all truths are implied by a falsehood, then not-p might imply both q and not-q [Fisher]
In relevance logic, conditionals help information to flow from antecedent to consequent [Fisher]
Logic formalizes how we should reason, but it shouldn't determine whether we are realists [Fisher]
Classical logic is: excluded middle, non-contradiction, contradictions imply all, disjunctive syllogism [Fisher]
We reach 'reflective equilibrium' when intuitions and theory completely align [Fisher]
