5. Theory of Logic / L. Paradox / 6. Paradoxes in Language / c. Grelling's paradox

10631

If 'x is heterological' iff it does not apply to itself, then 'heterological' is heterological if it isn't heterological

6. Mathematics / B. Foundations for Mathematics / 4. Axioms for Number / g. Incompleteness of Arithmetic

10624

The incompletability of formal arithmetic reveals that logic also cannot be completely characterized

6. Mathematics / B. Foundations for Mathematics / 7. Mathematical Structuralism / e. Structuralism critique

10629

If structures are relative, this undermines truth-value and objectivity

10628

The structural view of numbers doesn't fit their usage outside arithmetical contexts

6. Mathematics / C. Sources of Mathematics / 6. Logicism / c. Neo-logicism

10622

The neo-Fregean is more optimistic than Frege about contextual definitions of numbers

9. Objects / A. Existence of Objects / 2. Abstract Objects / c. Modern abstracta

10626

Objects just are what singular terms refer to

18. Thought / E. Abstraction / 7. Abstracta by Equivalence

10630

Abstracted objects are not mental creations, but depend on equivalence between given entities

19. Language / E. Analyticity / 2. Analytic Truths

10627
