9. Objects / B. Unity of Objects / 3. Unity Problems / c. Statue and clay
A statue is essentially the statue, but its lump is not essentially a statue, so statue isn't lump [Yablo, by Rocca]
     Full Idea: Yablo proposes the argument that Statue A is essentially a statue, and Lump 1 is not essentially a statue, so Statue A is not identical with Lump 1.
     From: report of Stephen Yablo (Identity, Essence and Indiscernibility [1987]) by Michael della Rocca - Essentialists and Essentialism I
     A reaction: Della Rocca and Yablo unashamedly elide necessary properties with essential properties, so this argument doesn't bother me too much. It concerns the statue and the clay having different modal properties.
13. Knowledge Criteria / B. Internal Justification / 3. Evidentialism / b. Evidentialism
It is always wrong to believe things on insufficient evidence [Clifford]
     Full Idea: It is wrong always, everywhere, and for anyone, to believe anything upon insufficient evidence.
     From: William K. Clifford (works [1870]), quoted by Robert Fogelin - Walking the Tightrope of Reason Ch.4
     A reaction: This is a famous remark, but is in danger of being tautological unless one gives some account of what 'insufficient' means. If Clifford means the evidence must be conclusive, this is nonsense. 'Never believe if there is no evidence' is better.
13. Knowledge Criteria / E. Relativism / 2. Knowledge as Convention
By nature people are close to one another, but culture drives them apart [Hippias]
     Full Idea: I regard you all as relatives - by nature, not by convention. By nature like is akin to like, but convention is a tyrant over humankind and often constrains people to act contrary to nature.
     From: Hippias (fragments/reports [c.430 BCE]), quoted by Plato - Protagoras 337c8
