3. Truth / A. Truth Problems / 2. Defining Truth
19125 If we define truth, we can eliminate it [Halbach/Leigh]
3. Truth / F. Semantic Truth / 1. Tarski's Truth / b. Satisfaction and truth
19128 If a language cannot name all objects, then satisfaction must be used, instead of unary truth [Halbach/Leigh]
3. Truth / F. Semantic Truth / 1. Tarski's Truth / c. Meta-language for truth
19120 Semantic theories need a powerful metalanguage, typically including set theory [Halbach/Leigh]
3. Truth / F. Semantic Truth / 2. Semantic Truth
19127 The T-sentences are deductively weak, and also not deductively conservative [Halbach/Leigh]
3. Truth / G. Axiomatic Truth / 1. Axiomatic Truth
19124 A natural theory of truth plays the role of reflection principles, establishing arithmetic's soundness [Halbach/Leigh]
19126 If deflationary truth is not explanatory, truth axioms should be 'conservative', proving nothing new [Halbach/Leigh]
3. Truth / G. Axiomatic Truth / 2. FS Truth Axioms
19129 The FS axioms use classical logical, but are not fully consistent [Halbach/Leigh]
3. Truth / G. Axiomatic Truth / 3. KF Truth Axioms
19130 KF is formulated in classical logic, but describes non-classical truth, which allows truth-value gluts [Halbach/Leigh]
5. Theory of Logic / E. Structures of Logic / 6. Relations in Logic
8525 Relations need terms, so they must be second-order entities based on first-order tropes [Campbell,K]
7. Existence / B. Change in Existence / 4. Events / c. Reduction of events
8518 Events are trope-sequences, in which tropes replace one another [Campbell,K]
8. Modes of Existence / B. Properties / 12. Denial of Properties
19121 We can reduce properties to true formulas [Halbach/Leigh]
8. Modes of Existence / B. Properties / 13. Tropes / a. Nature of tropes
8513 Two red cloths are separate instances of redness, because you can dye one of them blue [Campbell,K]
8514 Red could only recur in a variety of objects if it was many, which makes them particulars [Campbell,K]
8522 Tropes solve the Companionship Difficulty, since the resemblance is only between abstract particulars [Campbell,K]
8523 Tropes solve the Imperfect Community problem, as they can only resemble in one respect [Campbell,K]
8524 Trope theory makes space central to reality, as tropes must have a shape and size [Campbell,K]
8. Modes of Existence / E. Nominalism / 1. Nominalism / c. Nominalism about abstracta
19122 Nominalists can reduce theories of properties or sets to harmless axiomatic truth theories [Halbach/Leigh]
8. Modes of Existence / E. Nominalism / 2. Resemblance Nominalism
8521 Nominalism has the problem that without humans nothing would resemble anything else [Campbell,K]
9. Objects / A. Existence of Objects / 1. Physical Objects
8515 Tropes are basic particulars, so concrete particulars are collections of co-located tropes [Campbell,K]
8519 Bundles must be unique, so the Identity of Indiscernibles is a necessity - which it isn't! [Campbell,K]
9. Objects / F. Identity among Objects / 7. Indiscernible Objects
4033 Two pure spheres in non-absolute space are identical but indiscernible [Campbell,K]
18. Thought / E. Abstraction / 3. Abstracta by Ignoring
8512 Abstractions come before the mind by concentrating on a part of what is presented [Campbell,K]
22. Metaethics / C. The Good / 1. Goodness / g. Consequentialism
22457 If the aim is good outcomes, why are killings worse than deaths? [Scheffler, by Foot]
26. Natural Theory / C. Causation / 8. Particular Causation / b. Causal relata
8517 Causal conditions are particular abstract instances of properties, which makes them tropes [Campbell,K]
8516 Davidson can't explain causation entirely by events, because conditions are also involved [Campbell,K]
