7. Existence / C. Structure of Existence / 5. Supervenience / d. Humean supervenience
A homogeneous rotating disc should be undetectable according to Humean supervenience [Hawley]
     Full Idea: Imagine a perfectly homogeneous non-atomistic disc. A record of all the non-relational information about the world at that moment will not reveal whether the disc is rotating about a vertical axis through. This tells against Humean supervenience.
     From: Katherine Hawley (How Things Persist [2001], 3.2)
     A reaction: [Armstrong 1980 originated this, and it is famously discussed by Kripke in lectures] There will, of course, be dispositions present because of the rotation, but Lewis excludes any such modal truths.
7. Existence / D. Theories of Reality / 10. Vagueness / b. Vagueness of reality
Non-linguistic things cannot be indeterminate, because they don't have truth-values at all [Hawley]
     Full Idea: Non-linguistic objects, properties, and states of affairs cannot be indeterminate because they cannot have determinate truth-values either. No cloud is indeterminate, just as no cloud is either determinately true or determinately false.
     From: Katherine Hawley (How Things Persist [2001], 4.1)
     A reaction: If vagueness must be linguistic, this means animals can never experience it, which I doubt. Presumably 'this is a cloud' is only made vague by the vagueness of the object, rather than by the vagueness of the sentence?
Maybe for the world to be vague, it must be vague in its foundations? [Hawley]
     Full Idea: There is a question of whether there must be 'vagueness all the way down' for the world to be vague. One view is that if there is a base level of precisely describably facts, upon which all the others supervene, then the world is not really vague.
     From: Katherine Hawley (How Things Persist [2001], 4.5)
     A reaction: My understanding of the physics is that it is non-vague all the way down, and then you get to the base level which is hopelessly vague!
7. Existence / D. Theories of Reality / 10. Vagueness / c. Vagueness as ignorance
Epistemic vagueness seems right in the case of persons [Hawley]
     Full Idea: The epistemic account of vagueness is particularly attractive where persons are concerned.
     From: Katherine Hawley (How Things Persist [2001], 4.14)
     A reaction: You'll have to see her text for details. Interesting that there might be different views of what vagueness is for different cases. Or putting it another way, absolutely everything (said, thought, existing or done) might be vague in some way!
7. Existence / D. Theories of Reality / 10. Vagueness / f. Supervaluation for vagueness
Supervaluation refers to one vaguely specified thing, through satisfaction by everything in some range [Hawley]
     Full Idea: Supervaluationists take a present-tense predication as concerning a single, but vaguely specified, moment. …It is indeterminate which of a range of moments enters into the truth conditions, but it is true if satisfied by every member of the range.
     From: Katherine Hawley (How Things Persist [2001], 2.7)
     A reaction: She is discussing stage theory, but this is a helpful clarification of the idea of supervaluation. Something can be satisfied by a whole bunch of values, even though you are not sure which one.
Supervaluationism takes what the truth-value would have been if indecision was resolved [Hawley]
     Full Idea: A supervaluationist approach involves consideration of what the truth value of the utterance would have been if semantic indecision had been resolved in this way or that.
     From: Katherine Hawley (How Things Persist [2001], 4.1)
     A reaction: At last, a lovely account of supervaluation in plain English that anyone can understand! Why don't they all do that? Well, done Katherine Hawley! ['semantic indecision' is uncertainty about what your words mean!]
