Modern metaphysics pursues aesthetic criteria like story-writing, and abandons scientific truth [Ladyman/Ross]
1. Philosophy / F. Analytic Philosophy / 4. Conceptual Analysis
Why think that conceptual analysis reveals reality, rather than just how people think? [Ladyman/Ross]
1. Philosophy / G. Scientific Philosophy / 3. Scientism
A metaphysics based on quantum gravity could result in almost anything [Ladyman/Ross]
The supremacy of science rests on its iterated error filters [Ladyman/Ross]
We should abandon intuitions, especially that the world is made of little things, and made of something [Ladyman/Ross]

Anti-Razor: if you can't account for a truth, keep positing things until you can [Pasnau]
2. Reason / F. Fallacies / 8. Category Mistake / a. Category mistakes
People have dreams which involve category mistakes [Magidor]
Category mistakes are either syntactic, semantic, or pragmatic [Magidor]
2. Reason / F. Fallacies / 8. Category Mistake / b. Category mistake as syntactic
Category mistakes seem to be universal across languages [Magidor]
Category mistakes as syntactic needs a huge number of fine-grained rules [Magidor]
Embedded (in 'he said that…') category mistakes show syntax isn't the problem [Magidor]
2. Reason / F. Fallacies / 8. Category Mistake / c. Category mistake as semantic
Category mistakes are meaningful, because metaphors are meaningful category mistakes [Magidor]
The normal compositional view makes category mistakes meaningful [Magidor]
If a category mistake is synonymous across two languages, that implies it is meaningful [Magidor]
If a category mistake has unimaginable truth-conditions, then it seems to be meaningless [Magidor]
Two good sentences should combine to make a good sentence, but that might be absurd [Magidor]
A good explanation of why category mistakes sound wrong is that they are meaningless [Magidor]
Category mistakes are neither verifiable nor analytic, so verificationism says they are meaningless [Magidor]
Category mistakes play no role in mental life, so conceptual role semantics makes them meaningless [Magidor]
Maybe when you say 'two is green', the predicate somehow fails to apply? [Magidor]
If category mistakes aren't syntax failure or meaningless, maybe they just lack a truth-value? [Magidor]
2. Reason / F. Fallacies / 8. Category Mistake / d. Category mistake as pragmatic
Maybe the presuppositions of category mistakes are the abilities of things? [Magidor]
Category mistakes suffer from pragmatic presupposition failure (which is not mere triviality) [Magidor]
Category mistakes because of presuppositions still have a truth value (usually 'false') [Magidor]
In 'two is green', 'green' has a presupposition of being coloured [Magidor]
'Numbers are coloured and the number two is green' seems to be acceptable [Magidor]
2. Reason / F. Fallacies / 8. Category Mistake / e. Category mistake as ontological
The presuppositions in category mistakes reveal nothing about ontology [Magidor]
4. Formal Logic / E. Nonclassical Logics / 8. Intensional Logic
Intensional logic maps logical space, showing which predicates are compatible or incompatible [Magidor]

7. Existence / B. Change in Existence / 2. Processes
Any process can be described as transfer of measurable information [Ladyman/Ross]
7. Existence / C. Structure of Existence / 1. Grounding / a. Nature of grounding
Priority was a major topic of dispute for scholastics [Pasnau]
7. Existence / C. Structure of Existence / 6. Fundamentals / a. Fundamental reality
We say there is no fundamental level to ontology, and reality is just patterns [Ladyman/Ross]
7. Existence / C. Structure of Existence / 7. Abstract/Concrete / a. Abstract/concrete
If concrete is spatio-temporal and causal, and abstract isn't, the distinction doesn't suit physics [Ladyman/Ross]
Concrete and abstract are too crude for modern physics [Ladyman/Ross]
7. Existence / C. Structure of Existence / 8. Stuff / b. Mixtures
In mixtures, the four elements ceased to exist, replaced by a mixed body with a form [Pasnau]
7. Existence / D. Theories of Reality / 6. Physicalism
Physicalism is 'part-whole' (all parts are physical), or 'supervenience/levels' (dependence on physical) [Ladyman/Ross]
8. Modes of Existence / A. Relations / 1. Nature of Relations
Relations without relata must be treated as universals, with their own formal properties [Ladyman/Ross]
A belief in relations must be a belief in things that are related [Ladyman/Ross]
8. Modes of Existence / A. Relations / 2. Internal Relations
The normal assumption is that relations depend on properties of the relata [Ladyman/Ross]
8. Modes of Existence / A. Relations / 3. Structural Relations
That there are existent structures not made of entities is no stranger than the theory of universals [Ladyman/Ross]
8. Modes of Existence / B. Properties / 3. Types of Properties
17th C qualities are either microphysical, or phenomenal, or powers [Pasnau]
8. Modes of Existence / B. Properties / 5. Natural Properties
Causal essentialism says properties are nothing but causal relations [Ladyman/Ross]
8. Modes of Existence / B. Properties / 6. Categorical Properties
17th century authors only recognised categorical properties, never dispositions [Pasnau]
8. Modes of Existence / B. Properties / 8. Properties as Modes
The biggest question for scholastics is whether properties are real, or modes of substances [Pasnau]
8. Modes of Existence / C. Powers and Dispositions / 4. Powers as Essence
There is no centralised power, but we still need essence for a metaphysical understanding [Pasnau]
8. Modes of Existence / C. Powers and Dispositions / 6. Dispositions / a. Dispositions
Instead of adding Aristotelian forms to physical stuff, one could add dispositions [Pasnau]
8. Modes of Existence / C. Powers and Dispositions / 6. Dispositions / b. Dispositions and powers
Scholastics reject dispositions, because they are not actual, as forms require [Pasnau]
8. Modes of Existence / C. Powers and Dispositions / 6. Dispositions / e. Dispositions as potential
If science captures the modal structure of things, that explains why its predictions work [Ladyman/Ross]
9. Objects / A. Existence of Objects / 1. Physical Objects
Things are constructs for tracking patterns (and not linguistic, because animals do it) [Ladyman/Ross]
9. Objects / A. Existence of Objects / 5. Individuation / a. Individuation
Maybe individuation can be explained by thermodynamic depth [Ladyman/Ross]
Scholastics say there is a genuine thing if it is 'separable' [Pasnau]
9. Objects / A. Existence of Objects / 5. Individuation / b. Individuation by properties
If you reject essences, questions of individuation become extremely difficult [Pasnau]
Scholastics thought Quantity could be the principle of individuation [Pasnau]
9. Objects / A. Existence of Objects / 6. Nihilism about Objects
Physics seems to imply that we must give up self-subsistent individuals [Ladyman/Ross]
There is no single view of individuals, because different sciences operate on different scales [Ladyman/Ross]
There are no cats in quantum theory, and no mountains in astrophysics [Ladyman/Ross]
9. Objects / B. Unity of Objects / 1. Unifying an Object / c. Unity as conceptual
Things are abstractions from structures [Ladyman/Ross]
9. Objects / B. Unity of Objects / 2. Substance / a. Substance
Corpuscularianism promised a decent account of substance [Pasnau]
Corpuscularian critics of scholasticism say only substances exist [Pasnau]
Scholastics wanted to treat Aristotelianism as physics, rather than as metaphysics [Pasnau]
If crowds are things at all, they seem to be Substances, since they bear properties [Pasnau]
9. Objects / B. Unity of Objects / 2. Substance / c. Types of substance
Scholastics use 'substantia' for thick concrete entities, and for thin metaphysical ones [Pasnau]
9. Objects / B. Unity of Objects / 2. Substance / e. Substance critique
For corpuscularians, a substance is just its integral parts [Pasnau]
9. Objects / B. Unity of Objects / 3. Unity Problems / c. Statue and clay
We can explain the statue/clay problem by a category mistake with a false premise [Magidor]
If clay survives destruction of the statue, the statue wasn't a substance, but a mere accident [Pasnau]
9. Objects / C. Structure of Objects / 2. Hylomorphism / a. Hylomorphism
Corpuscularianism rejected not only form, but also the dependence of matter on form [Pasnau]
9. Objects / C. Structure of Objects / 2. Hylomorphism / b. Form as principle
Hylomorphism may not be a rival to science, but an abstract account of unity and endurance [Pasnau]
9. Objects / C. Structure of Objects / 2. Hylomorphism / c. Form as causal
Hylomorphism declined because scholastics made it into a testable physical theory [Pasnau]
Scholastics made forms substantial, in a way unintended by Aristotle [Pasnau]
Scholastics began to see substantial form more as Aristotle's 'efficient' cause [Pasnau]
9. Objects / C. Structure of Objects / 2. Hylomorphism / d. Form as unifier
Aquinas says a substance has one form; Scotists say it has many forms [Pasnau]
9. Objects / C. Structure of Objects / 4. Quantity of an Object
Scholastic Quantity either gives a body parts, or spreads them out in a unified way [Pasnau]
9. Objects / C. Structure of Objects / 5. Composition of an Object
The idea of composition, that parts of the world are 'made of' something, is no longer helpful [Ladyman/Ross]
9. Objects / C. Structure of Objects / 7. Substratum
A substrate may be 'prime matter', which endures through every change [Pasnau]
There may be different types of substrate, or temporary substrates [Pasnau]
A substratum can't be 'bare', because it has a job to do [Pasnau]
If a substrate gives causal support for change, quite a lot of the ingredients must endure [Pasnau]
9. Objects / C. Structure of Objects / 8. Parts of Objects / c. Wholes from parts
A sum of things is not a whole if the whole does not support some new generalisation [Ladyman/Ross]
9. Objects / D. Essence of Objects / 7. Essence and Necessity / b. Essence not necessities
Aristotelians deny that all necessary properties are essential [Pasnau]
9. Objects / D. Essence of Objects / 13. Nominal Essence
We treat the core of a pattern as an essence, in order to keep track of it [Ladyman/Ross]
9. Objects / E. Objects over Time / 1. Objects over Time
A continuous object might be a type, with instances at each time [Ladyman/Ross]
9. Objects / E. Objects over Time / 6. Successive Things
Typical successive things are time and motion [Pasnau]
9. Objects / E. Objects over Time / 10. Beginning of an Object
Weak ex nihilo says it all comes from something; strong version says the old must partly endure [Pasnau]

Quantum mechanics seems to imply single-case probabilities [Ladyman/Ross]
In quantum statistics, two separate classical states of affairs are treated as one [Ladyman/Ross]

Rats find some obvious associations easier to learn than less obvious ones [Ladyman/Ross]
12. Knowledge Sources / D. Empiricism / 5. Empiricism Critique
The doctrine of empiricism does not itself seem to be empirically justified [Ladyman/Ross]
12. Knowledge Sources / E. Direct Knowledge / 2. Intuition
There is no reason to think our intuitions are good for science or metaphysics [Ladyman/Ross]
14. Science / A. Basis of Science / 4. Prediction
The theory of evolution was accepted because it explained, not because of its predictions [Ladyman/Ross]
What matters is whether a theory can predict - not whether it actually does so [Ladyman/Ross]
14. Science / B. Scientific Theories / 8. Ramsey Sentences
The Ramsey sentence describes theoretical entities; it skips reference, but doesn't eliminate it [Ladyman/Ross]
The Ramsey-sentence approach preserves observations, but eliminates unobservables [Ladyman/Ross]
14. Science / C. Induction / 1. Induction
Induction is reasoning from the observed to the unobserved [Ladyman/Ross]
14. Science / C. Induction / 4. Reason in Induction
Inductive defences of induction may be rule-circular, but not viciously premise-circular [Ladyman/Ross]
14. Science / D. Explanation / 2. Types of Explanation / c. Explanations by coherence
We explain by deriving the properties of a phenomenon by embedding it in a large abstract theory [Ladyman/Ross]
14. Science / D. Explanation / 2. Types of Explanation / k. Explanations by essence
Essences must explain, so we can infer them causally from the accidents [Pasnau]
15. Nature of Minds / C. Capacities of Minds / 4. Objectification
Maybe the only way we can think about a domain is by dividing it up into objects [Ladyman/Ross]
16. Persons / F. Free Will / 6. Determinism / a. Determinism
Two versions of quantum theory say that the world is deterministic [Ladyman/Ross]
17. Mind and Body / D. Property Dualism / 4. Emergentism
Science is opposed to downward causation [Ladyman/Ross]
18. Thought / A. Modes of Thought / 2. Propositional Attitudes
Propositional attitudes relate agents to either propositions, or meanings, or sentence/utterances [Magidor]
18. Thought / C. Content / 1. Content
Two sentences with different meanings can, on occasion, have the same content [Magidor]
18. Thought / D. Concepts / 4. Structure of Concepts / b. Analysis of concepts
To grasp 'two' and 'green', must you know that two is not green? [Magidor]
19. Language / C. Assigning Meanings / 1. Syntax
Generative semantics says structure is determined by semantics as well as syntactic rules [Magidor]
'John is easy to please' and 'John is eager to please' have different deep structure [Magidor]
19. Language / C. Assigning Meanings / 2. Semantics
The semantics of a sentence is its potential for changing a context [Magidor]
19. Language / C. Assigning Meanings / 4. Compositionality
Weaker compositionality says meaningful well-formed sentences get the meaning from the parts [Magidor]
Strong compositionality says meaningful expressions syntactically well-formed are meaningful [Magidor]
Understanding unlimited numbers of sentences suggests that meaning is compositional [Magidor]
19. Language / D. Propositions / 2. Abstract Propositions / b. Propositions as possible worlds
Are there partial propositions, lacking truth value in some possible worlds? [Magidor]
19. Language / F. Communication / 5. Pragmatics / a. Contextual meaning
A sentence can be meaningful, and yet lack a truth value [Magidor]
In the pragmatic approach, presuppositions are assumed in a context, for successful assertion [Magidor]
19. Language / F. Communication / 5. Pragmatics / b. Implicature
The infelicitiousness of trivial truth is explained by uninformativeness, or a static context-set [Magidor]
The infelicitiousness of trivial falsity is explained by expectations, or the loss of a context-set [Magidor]
19. Language / F. Communication / 5. Pragmatics / c. Presupposition
A presupposition is what makes an utterance sound wrong if it is not assumed? [Magidor]
A test for presupposition would be if it provoked 'hey wait a minute - I have no idea that....' [Magidor]
The best tests for presupposition are projecting it to negation, conditional, conjunction, questions [Magidor]
If both s and not-s entail a sentence p, then p is a presupposition [Magidor]
Why do certain words trigger presuppositions? [Magidor]
19. Language / F. Communication / 6. Interpreting Language / d. Metaphor
One theory says metaphors mean the same as the corresponding simile [Magidor]
Theories of metaphor divide over whether they must have literal meanings [Magidor]
The simile view of metaphors removes their magic, and won't explain why we use them [Magidor]
Maybe a metaphor is just a substitute for what is intended literally, like 'icy' for 'unemotional' [Magidor]
Gricean theories of metaphor involve conversational implicatures based on literal meanings [Magidor]
Non-cognitivist views of metaphor says there are no metaphorical meanings, just effects of the literal [Magidor]
Metaphors tend to involve category mistakes, by joining disjoint domains [Magidor]
Metaphors as substitutes for the literal misses one predicate varying with context [Magidor]
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / g. Atomism
Atomists say causation is mechanical collisions, and all true qualities are microscopic [Pasnau]
26. Natural Theory / A. Speculations on Nature / 7. Later Matter Theories / a. Early Modern matter
In the 17th C matter became body, and was then studied by science [Pasnau]
26. Natural Theory / A. Speculations on Nature / 7. Later Matter Theories / b. Corpuscles
Atomism is the commonest version of corpuscularianism, but isn't required by it [Pasnau]
If there are just arrangements of corpuscles, where are the boundaries between substances? [Pasnau]
26. Natural Theory / B. Natural Kinds / 3. Knowing Kinds
Explanation by kinds and by clusters of properties just express the stability of reality [Ladyman/Ross]
26. Natural Theory / B. Natural Kinds / 4. Source of Kinds
There is nothing more to a natural kind than a real pattern in nature [Ladyman/Ross]
26. Natural Theory / C. Causation / 2. Types of cause
Scholastic causation is by changes in the primary qualities of hot, cold, wet, dry [Pasnau]
26. Natural Theory / C. Causation / 7. Eliminating causation
Causation is found in the special sciences, but may have no role in fundamental physics [Ladyman/Ross]
26. Natural Theory / D. Laws of Nature / 1. Laws of Nature
Science may have uninstantiated laws, inferred from approaching some unrealised limit [Ladyman/Ross]
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / a. Scientific essentialism
Substantial forms were a step towards scientific essentialism [Pasnau]
27. Natural Reality / B. Modern Physics / 4. Standard Model / a. Concept of matter
That the universe must be 'made of' something is just obsolete physics [Ladyman/Ross]
In physics, matter is an emergent phenomenon, not part of fundamental ontology [Ladyman/Ross]
27. Natural Reality / C. Space / 6. Space-Time
Spacetime may well be emergent, rather than basic [Ladyman/Ross]
If spacetime is substantial, what is the substance? [Ladyman/Ross]
27. Natural Reality / D. Time / 1. Nature of Time / h. Presentism
A fixed foliation theory of quantum gravity could make presentism possible [Ladyman/Ross]
27. Natural Reality / E. Cosmology / 3. The Beginning
Scholastic authors agree that matter was created by God, out of nothing [Pasnau]
29. Religion / B. Monotheistic Religion / 4. Christianity / b. Transubstantiation
Transubstantion says accidents of bread and wine don't inhere in the substance [Pasnau]
