10 ideas

1. Philosophy / D. Nature of Philosophy / 1. Philosophy

20435

If philosophy could be summarised it would be pointless [Adorno]

6. Mathematics / A. Nature of Mathematics / 2. Geometry

16901

The equivalent algebra model of geometry loses some essential spatial meaning [Burge]

6. Mathematics / B. Foundations for Mathematics / 4. Axioms for Number / d. Peano arithmetic

16902

Peano arithmetic requires grasping 0 as a primitive number [Burge]

7. Existence / D. Theories of Reality / 10. Vagueness / b. Vagueness of reality

16129

Evans argues (falsely!) that a contradiction follows from treating objects as vague [Evans, by Lowe]

16459

Is it coherent that reality is vague, identities can be vague, and objects can have fuzzy boundaries? [Evans]

16460

Evans assumes there can be vague identity statements, and that his proof cannot be right [Evans, by Lewis]

16457

There clearly are vague identity statements, and Evans's argument has a false conclusion [Evans, by Lewis]

9. Objects / B. Unity of Objects / 3. Unity Problems / e. Vague objects

14484

If a=b is indeterminate, then a=/=b, and so there cannot be indeterminate identity [Evans, by Thomasson]

9. Objects / F. Identity among Objects / 6. Identity between Objects

16224

There can't be vague identity; a and b must differ, since a, unlike b, is only vaguely the same as b [Evans, by PG]

12. Knowledge Sources / A. A Priori Knowledge / 1. Nature of the A Priori

16892

Is apriority predicated mainly of truths and proofs, or of human cognition? [Burge]
