2. Reason / D. Definition / 8. Impredicative Definition
Predicative definitions are acceptable in mathematics if they distinguish objects, rather than creating them? [Zermelo, by Lavine]
3. Truth / A. Truth Problems / 3. Value of Truth
Truth is not a object we love - it is the radiant manifestation of reality [Weil]
4. Formal Logic / F. Set Theory ST / 1. Set Theory
We take set theory as given, and retain everything valuable, while avoiding contradictions [Zermelo]
Set theory investigates number, order and function, showing logical foundations for mathematics [Zermelo]
4. Formal Logic / F. Set Theory ST / 4. Axioms for Sets / a. Axioms for sets
ZFC: Existence, Extension, Specification, Pairing, Unions, Powers, Infinity, Choice [Zermelo, by Clegg]
Zermelo published his axioms in 1908, to secure a controversial proof [Zermelo, by Maddy]
Set theory can be reduced to a few definitions and seven independent axioms [Zermelo]
4. Formal Logic / F. Set Theory ST / 4. Axioms for Sets / c. Axiom of Pairing II
Zermelo introduced Pairing in 1930, and it seems fairly obvious [Zermelo, by Maddy]
4. Formal Logic / F. Set Theory ST / 4. Axioms for Sets / i. Axiom of Foundation VIII
Zermelo used Foundation to block paradox, but then decided that only Separation was needed [Zermelo, by Maddy]
4. Formal Logic / F. Set Theory ST / 4. Axioms for Sets / m. Axiom of Separation
The Axiom of Separation requires set generation up to one step back from contradiction [Zermelo, by Maddy]
Not every predicate has an extension, but Separation picks the members that satisfy a predicate [Zermelo, by Hart,WD]
6. Mathematics / A. Nature of Mathematics / 3. Nature of Numbers / e. Ordinal numbers
In ZF, the Burali-Forti Paradox proves that there is no set of all ordinals [Zermelo, by Hart,WD]
6. Mathematics / B. Foundations for Mathematics / 5. Definitions of Number / f. Zermelo numbers
For Zermelo the successor of n is {n} (rather than n U {n}) [Zermelo, by Maddy]
6. Mathematics / B. Foundations for Mathematics / 6. Mathematics as Set Theory / a. Mathematics is set theory
Zermelo believed, and Von Neumann seemed to confirm, that numbers are sets [Zermelo, by Maddy]
6. Mathematics / B. Foundations for Mathematics / 7. Mathematical Structuralism / e. Structuralism critique
Different versions of set theory result in different underlying structures for numbers [Zermelo, by Brown,JR]
7. Existence / C. Structure of Existence / 1. Grounding / a. Nature of grounding
Creation produced a network or web of determinations [Weil]
13. Knowledge Criteria / A. Justification Problems / 2. Justification Challenges / a. Agrippa's trilemma
There are five possible responses to the problem of infinite regress in justification [Cleve]
13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / a. Foundationalism
Modern foundationalists say basic beliefs are fallible, and coherence is relevant [Cleve]
21. Aesthetics / A. Aesthetic Experience / 4. Beauty
The aesthete's treatment of beauty as amusement is sacreligious; beauty should nourish [Weil]
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / a. Idealistic ethics
Beauty is the proof of what is good [Weil]
23. Ethics / C. Virtue Theory / 3. Virtues / h. Respect
Respect is our only obligation, which can only be expressed through deeds, not words [Weil]
24. Political Theory / A. Basis of a State / 1. A People / b. The natural life
The most important human need is to have multiple roots [Weil]
24. Political Theory / A. Basis of a State / 1. A People / c. A unified people
The need for order stands above all others, and is understood via the other needs [Weil]

Party politics in a democracy can't avoid an anti-democratic party [Weil]
24. Political Theory / D. Ideologies / 8. Socialism
Socialism tends to make a proletariat of the whole population [Weil]
24. Political Theory / D. Ideologies / 11. Capitalism
The capitalists neglect the people and the nation, and even their own interests [Weil]
25. Social Practice / B. Equalities / 1. Grounds of equality
By making money the sole human measure, inequality has become universal [Weil]
25. Social Practice / C. Rights / 1. Basis of Rights
People have duties, and only have rights because of the obligations of others to them [Weil]
25. Social Practice / D. Justice / 3. Punishment / a. Right to punish
