6. Mathematics / C. Sources of Mathematics / 7. Formalism
The subject matter of mathematics is immediate and clear concrete symbols [Hilbert]
6. Mathematics / C. Sources of Mathematics / 8. Finitism
Mathematics divides in two: meaningful finitary statements, and empty idealised statements [Hilbert]

Intuitionism says that totality of numbers is only potential, but is still determinate [Dummett]
7. Existence / C. Structure of Existence / 7. Abstract/Concrete / a. Abstract/concrete
Ostension is possible for concreta; abstracta can only be referred to via other objects [Dummett, by Hale]
The concrete/abstract distinction seems crude: in which category is the Mistral? [Dummett]
We don't need a sharp concrete/abstract distinction [Dummett]
We can't say that light is concrete but radio waves abstract [Dummett]
7. Existence / D. Theories of Reality / 11. Ontological Commitment / a. Ontological commitment
The context principle for names rules out a special philosophical sense for 'existence' [Dummett]
The objects we recognise the world as containing depends on the structure of our language [Dummett]
8. Modes of Existence / D. Universals / 1. Universals
We can understand universals by studying predication [Dummett]
8. Modes of Existence / E. Nominalism / 1. Nominalism / a. Nominalism
'Nominalism' used to mean denial of universals, but now means denial of abstract objects [Dummett]
9. Objects / A. Existence of Objects / 1. Physical Objects
Concrete objects such as sounds and smells may not be possible objects of ostension [Dummett]
9. Objects / A. Existence of Objects / 2. Abstract Objects / a. Nature of abstracta
Abstract objects may not cause changes, but they can be the subject of change [Dummett]
9. Objects / A. Existence of Objects / 2. Abstract Objects / b. Need for abstracta
If we can intuitively apprehend abstract objects, this makes them observable and causally active [Dummett]
9. Objects / A. Existence of Objects / 2. Abstract Objects / c. Modern abstracta
Abstract objects must have names that fall within the range of some functional expression [Dummett]
9. Objects / A. Existence of Objects / 2. Abstract Objects / d. Problems with abstracta
If a genuine singular term needs a criterion of identity, we must exclude abstract nouns [Dummett, by Hale]
Abstract objects can never be confronted, and need verbal phrases for reference [Dummett]
9. Objects / A. Existence of Objects / 3. Objects in Thought
There is a modern philosophical notion of 'object', first introduced by Frege [Dummett]
11. Knowledge Aims / B. Certain Knowledge / 1. Certainty
My theory aims at the certitude of mathematical methods [Hilbert]
12. Knowledge Sources / B. Perception / 7. Causal Perception
Perceptual concepts can't just refer to what causes classification [Papineau]
15. Nature of Minds / A. Nature of Mind / 1. Mind / e. Questions about mind
The only serious mind-brain theories now are identity, token identity, realization and supervenience [Papineau]
15. Nature of Minds / A. Nature of Mind / 3. Mental Causation
Maybe mind and body do overdetermine acts, but are linked (for some reason) [Papineau]
15. Nature of Minds / A. Nature of Mind / 4. Other Minds / c. Knowing other minds
Young children can see that other individuals sometimes have false beliefs [Papineau]
Do we understand other minds by simulation-theory, or by theory-theory? [Papineau]
15. Nature of Minds / A. Nature of Mind / 8. Brain
Researching phenomenal consciousness is peculiar, because the concepts involved are peculiar [Papineau]
15. Nature of Minds / B. Features of Minds / 1. Consciousness / a. Consciousness
Whether octopuses feel pain is unclear, because our phenomenal concepts are too vague [Papineau]
Our concept of consciousness is crude, and lacks theoretical articulation [Papineau]
We can’t decide what 'conscious' means, so it is undecidable whether cats are conscious [Papineau]
15. Nature of Minds / B. Features of Minds / 1. Consciousness / e. Cause of consciousness
Maybe a creature is conscious if its mental states represent things in a distinct way [Papineau]
15. Nature of Minds / B. Features of Minds / 1. Consciousness / f. Higher-order thought
The 'actualist' HOT theory says consciousness comes from actual higher judgements of mental states [Papineau]
Actualist HOT theories imply that a non-conscious mental event could become conscious when remembered [Papineau]
States are conscious if they could be the subject of higher-order mental judgements [Papineau]
Higher-order judgements may be possible where the subject denies having been conscious [Papineau]
17. Mind and Body / A. Mind-Body Dualism / 6. Epiphenomenalism
The epiphenomenal relation of mind and brain is a 'causal dangler', unlike anything else [Papineau]
Maybe minds do not cause actions, but do cause us to report our decisions [Papineau]
17. Mind and Body / C. Functionalism / 8. Functionalism critique
Role concepts either name the realising property, or the higher property constituting the role [Papineau]
17. Mind and Body / D. Property Dualism / 2. Anomalous Monism
If causes are basic particulars, this doesn't make conscious and physical properties identical [Papineau]
17. Mind and Body / D. Property Dualism / 5. Supervenience of mind
Supervenience can be replaced by identifying mind with higher-order or disjunctional properties [Papineau]
17. Mind and Body / E. Mind as Physical / 1. Physical Mind
The completeness of physics is needed for mind-brain identity [Papineau]
17. Mind and Body / E. Mind as Physical / 2. Reduction of Mind
Mind-brain reduction is less explanatory, because phenomenal concepts lack causal roles [Papineau]
Weak reduction of mind is to physical causes; strong reduction is also to physical laws [Papineau]
17. Mind and Body / E. Mind as Physical / 5. Causal Argument
It is absurd to think that physical effects are caused twice, so conscious causes must be physical [Papineau]
17. Mind and Body / E. Mind as Physical / 6. Conceptual Dualism
Accept ontological monism, but conceptual dualism; we think in a different way about phenomenal thought [Papineau]
17. Mind and Body / E. Mind as Physical / 7. Anti-Physicalism / c. Knowledge argument
Mary acquires new concepts; she previously thought about the same property using material concepts [Papineau]
18. Thought / A. Modes of Thought / 1. Thought
Thinking about a thing doesn't require activating it [Papineau]
Consciousness affects bodily movement, so thoughts must be material states [Papineau]
18. Thought / C. Content / 6. Broad Content
Most reductive accounts of representation imply broad content [Papineau]
If content hinges on matters outside of you, how can it causally influence your actions? [Papineau]

Concepts only have a 'functional character', because they map to truth values, not objects [Dummett, by Davidson]

Since abstract objects cannot be picked out, we must rely on identity statements [Dummett]
19. Language / A. Nature of Meaning / 5. Meaning as Verification
Verificationists tend to infer indefinite answers from undecidable questions [Papineau]
19. Language / B. Reference / 3. Direct Reference / b. Causal reference
A realistic view of reference is possible for concrete objects, but not for abstract objects [Dummett, by Hale]
19. Language / C. Assigning Meanings / 2. Semantics
Teleosemantics equates meaning with the item the concept is intended to track [Papineau]
19. Language / C. Assigning Meanings / 8. Possible Worlds Semantics
Truth conditions in possible worlds can't handle statements about impossibilities [Papineau]
Thought content is possible worlds that make the thought true; if that includes the actual world, it's true [Papineau]
26. Natural Theory / C. Causation / 8. Particular Causation / b. Causal relata
Causation is based on either events, or facts, or states of affairs [Papineau]
Causes are instantiations of properties by particulars, or they are themselves basic particulars [Papineau]
26. Natural Theory / D. Laws of Nature / 10. Closure of Physics
The completeness of physics cannot be proved [Papineau]
Determinism is possible without a complete physics, if mental forces play a role [Papineau]
