2. Reason / A. Nature of Reason / 1. On Reason
17892

For clear questions posed by reason, reason can also find clear answers

5. Theory of Logic / A. Overview of Logic / 7. SecondOrder Logic
9188

Gödel proved that firstorder logic is complete, and secondorder logic incomplete [Dummett]

5. Theory of Logic / I. Semantics of Logic / 2. Formal Truth
10620

Originally truth was viewed with total suspicion, and only demonstrability was accepted

5. Theory of Logic / K. Features of Logics / 5. Incompleteness
17883

Gödel's Theorems did not refute the claim that all good mathematical questions have answers [Koellner]

6. Mathematics / B. Foundations for Mathematics / 4. Axioms for Number / g. Incompleteness of Arithmetic
17885

Gödel eventually hoped for a generalised completeness theorem leaving nothing undecidable [Koellner]

The real reason for Incompleteness in arithmetic is inability to define truth in a language
