Anti-Razor: if you can't account for a truth, keep positing things until you can [Pasnau]
3. Truth / B. Truthmakers / 10. Making Future Truths
In the tenseless view, all times are equally real, so statements of the future have truth-values [Le Poidevin]

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 says in any two physically indiscernible worlds the positive facts are the same [Chalmers, by Bennett,K]
7. Existence / E. Categories / 3. Proposed Categories
All facts are either physical, experiential, laws of nature, second-order final facts, or indexical facts about me [Chalmers]
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 / 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]
9. Objects / A. Existence of Objects / 5. Individuation / a. Individuation
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 / 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
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 / 7. Substratum
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]
A substrate may be 'prime matter', which endures through every change [Pasnau]
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 / 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]
10. Modality / A. Necessity / 5. Metaphysical Necessity
Strong metaphysical necessity allows fewer possible worlds than logical necessity [Chalmers]
Metaphysical necessity is a bizarre, brute and inexplicable constraint on possibilities [Chalmers]
10. Modality / A. Necessity / 10. Impossibility
How can we know the metaphysical impossibilities; the a posteriori only concerns this world [Chalmers]
10. Modality / D. Knowledge of Modality / 1. A Priori Necessary
Kripke is often taken to be challenging a priori insights into necessity [Chalmers]
10. Modality / D. Knowledge of Modality / 4. Conceivable as Possible / a. Conceivable as possible
Maybe logical possibility does imply conceivability - by an ideal mind [Chalmers]
Modal Rationalism: conceivability gives a priori access to modal truths [Chalmers, by Stalnaker]
Evaluate primary possibility from some world, and secondary possibility from this world [Chalmers, by Vaidya]
10. Modality / D. Knowledge of Modality / 4. Conceivable as Possible / b. Conceivable but impossible
One can wrongly imagine two things being non-identical even though they are the same (morning/evening star) [Chalmers]
11. Knowledge Aims / A. Knowledge / 4. Belief / a. Beliefs
We attribute beliefs to people in order to explain their behaviour [Chalmers]
12. Knowledge Sources / A. A Priori Knowledge / 4. A Priori as Necessities
A sentence is a priori if no possible way the world might actually be could make it false [Chalmers]
12. Knowledge Sources / B. Perception / 1. Perception
'Perception' means either an action or a mental state [Chalmers]
12. Knowledge Sources / B. Perception / 4. Sense Data / a. Sense-data theory
The structure of the retina has already simplified the colour information which hits it [Chalmers]
14. Science / B. Scientific Theories / 2. Aim of Science
We want illuminating theories, rather than coherent theories [Le Poidevin]
14. Science / D. Explanation / 2. Types of Explanation / a. Types of explanation
In addition to causal explanations, they can also be inferential, or definitional, or purposive [Le Poidevin]
14. Science / D. Explanation / 2. Types of Explanation / j. Explanations by reduction
Reductive explanation is not the be-all and the end-all of explanation [Chalmers]
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]

Going down the scale, where would consciousness vanish? [Chalmers]
15. Nature of Minds / B. Features of Minds / 3. Privacy
Nothing in physics even suggests consciousness [Chalmers]
15. Nature of Minds / B. Features of Minds / 4. Intentionality / b. Intentionality theories
Is intentionality just causal connections? [Chalmers]

15. Nature of Minds / B. Features of Minds / 6. Inverted Qualia
It seems possible to invert qualia [Chalmers]
15. Nature of Minds / B. Features of Minds / 7. Blindsight
In blindsight both qualia and intentionality are missing [Chalmers]
16. Persons / C. Self-Awareness / 4. Errors in Introspection
When distracted we can totally misjudge our own experiences [Chalmers]

17. Mind and Body / A. Mind-Body Dualism / 3. Panpsychism
It is odd if experience is a very recent development [Chalmers]
17. Mind and Body / A. Mind-Body Dualism / 7. Zombies
If I can have a zombie twin, my own behaviour doesn't need consciousness [Chalmers]
17. Mind and Body / C. Functionalism / 3. Psycho-Functionalism
Does consciousness arise from fine-grained non-reductive functional organisation? [Chalmers]
17. Mind and Body / C. Functionalism / 7. Chinese Room
Maybe the whole Chinese Room understands Chinese, though the person doesn't [Chalmers]
17. Mind and Body / C. Functionalism / 8. Functionalism critique
The Chinese Mind doesn't seem conscious, but then nor do brains from outside [Chalmers]
17. Mind and Body / D. Property Dualism / 3. Property Dualism
H2O causes liquidity, but no one is a dualist about that [Chalmers]
17. Mind and Body / D. Property Dualism / 4. Emergentism

17. Mind and Body / D. Property Dualism / 6. Mysterianism
Phenomenal consciousness is fundamental, with no possible nonphenomenal explanation [Chalmers, by Kriegel/Williford]
Nothing external shows whether a mouse is conscious [Chalmers]
17. Mind and Body / E. Mind as Physical / 7. Anti-Physicalism / b. Multiple realisability
Temperature (etc.) is agreed to be reducible, but it is multiply realisable [Chalmers]
18. Thought / A. Modes of Thought / 9. Indexical Thought
Indexicals may not be objective, but they are a fact about the world as I see it [Chalmers]
19. Language / C. Assigning Meanings / 9. Indexical Semantics
We don't just describe a time as 'now' from a private viewpoint, but as a fact about the world [Le Poidevin]
19. Language / C. Assigning Meanings / 10. Two-Dimensional Semantics
Rationalist 2D semantics posits necessary relations between meaning, apriority, and possibility [Chalmers, by Schroeter]
The 'primary intension' is non-empirical, and fixes extensions based on the actual-world reference [Chalmers]
Meaning has split into primary ("watery stuff"), and secondary counterfactual meaning ("H2O") [Chalmers]
The 'secondary intension' is determined by rigidifying (as H2O) the 'water' picked out in the actual world [Chalmers]
Primary and secondary intensions are the a priori (actual) and a posteriori (counterfactual) aspects of meaning [Chalmers]
We have 'primary' truth-conditions for the actual world, and derived 'secondary' ones for counterfactual worlds [Chalmers]
'Water' is two-dimensionally inconstant, with different intensions in different worlds [Chalmers, by Sider]
19. Language / D. Propositions / 1. Propositions
Two-dimensional semantics gives a 'primary' and 'secondary' proposition for each statement [Chalmers]
19. Language / E. Analyticity / 2. Analytic Truths
In two-dimensional semantics we have two aspects to truth in virtue of meaning [Chalmers]
22. Metaethics / B. Value / 2. Values / e. Death
It is disturbing if we become unreal when we die, but if time is unreal, then we remain real after death [Le Poidevin]
22. Metaethics / B. Value / 2. Values / j. Evil
Evil can't be an illusion, because then the illusion that there is evil would be evil [Le Poidevin]
23. Ethics / F. Existentialism / 1. Existentialism
Existentialism focuses on freedom and self-making, and insertion into the world [Le Poidevin]
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 / C. Causation / 1. Causation
The logical properties of causation are asymmetry, transitivity and irreflexivity [Le Poidevin]
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 / D. Laws of Nature / 8. Scientific Essentialism / a. Scientific essentialism
Substantial forms were a step towards scientific essentialism [Pasnau]
27. Natural Reality / C. Space / 3. Points in Space
We can identify unoccupied points in space, so they must exist [Le Poidevin]
If spatial points exist, then they must be stationary, by definition [Le Poidevin]
27. Natural Reality / C. Space / 4. Substantival Space
Absolute space explains actual and potential positions, and geometrical truths [Le Poidevin]
27. Natural Reality / C. Space / 5. Relational Space
For relationists moving an object beyond the edge of space creates new space [Le Poidevin]
27. Natural Reality / C. Space / 6. Space-Time
We distinguish time from space, because it passes, and it has a unique present moment [Le Poidevin]
27. Natural Reality / D. Time / 1. Nature of Time / e. Eventless time
Since nothing occurs in a temporal vacuum, there is no way to measure its length [Le Poidevin]
Temporal vacuums would be unexperienced, unmeasured, and unending [Le Poidevin]
27. Natural Reality / D. Time / 1. Nature of Time / g. Growing block
If the future is not real, we don't seem to have any obligation to future individuals [Le Poidevin]
27. Natural Reality / D. Time / 1. Nature of Time / h. Presentism
If things don't persist through time, then change makes no sense [Le Poidevin]
27. Natural Reality / D. Time / 2. Passage of Time / b. Rate of time
Time can't speed up or slow down, so it doesn't seem to be a 'process' [Le Poidevin]
27. Natural Reality / D. Time / 2. Passage of Time / c. Tenses and time
At the very least, minds themselves seem to be tensed [Le Poidevin]
Fiction seems to lack a tensed perspective, and offers an example of tenseless language [Le Poidevin]
It is the view of the future that really decides between tensed and tenseless views of time [Le Poidevin]
27. Natural Reality / D. Time / 2. Passage of Time / d. Time series
In the B-series, time-positions are unchanging; in the A-series they change (from future to present to past) [Le Poidevin]
Things which have ceased change their A-series position; things that persist change their B-series position [Le Poidevin]
A-theory says past, present, future and flow exist; B-theory says this just reports our perspective [Le Poidevin]
27. Natural Reality / D. Time / 2. Passage of Time / e. Tensed (A) series
It is claimed that the tense view entails the unreality of both future and past [Le Poidevin]
Tensed theorists typically try to reduce the tenseless to the tensed [Le Poidevin]
We share a common now, but not a common here [Le Poidevin]
27. Natural Reality / D. Time / 2. Passage of Time / f. Tenseless (B) series
The new tenseless theory offers indexical truth-conditions, instead of a reductive analysis [Le Poidevin]
To say that the past causes the present needs them both to be equally real [Le Poidevin]
The B-series doesn't seem to allow change [Le Poidevin]
If the B-universe is eternal, why am I trapped in a changing moment of it? [Le Poidevin]
27. Natural Reality / D. Time / 2. Passage of Time / g. Time's arrow
An ordered series can be undirected, but time favours moving from earlier to later [Le Poidevin]
If time's arrow is causal, how can there be non-simultaneous events that are causally unconnected? [Le Poidevin]
If time's arrow is psychological then different minds can impose different orders on events [Le Poidevin]
There are Thermodynamic, Psychological and Causal arrows of time [Le Poidevin]
Presumably if time's arrow is thermodynamic then time ends when entropy is complete [Le Poidevin]
If time is thermodynamic then entropy is necessary - but the theory says it is probable [Le Poidevin]
Time's arrow is not causal if there is no temporal gap between cause and effect [Le Poidevin]
27. Natural Reality / D. Time / 2. Passage of Time / i. Time and motion
Instantaneous motion is an intrinsic disposition to be elsewhere [Le Poidevin]
The dynamic view of motion says it is primitive, and not reducible to objects, properties and times [Le Poidevin]
27. Natural Reality / D. Time / 2. Passage of Time / k. Temporal truths
If the present could have diverse pasts, then past truths can't have present truthmakers [Le Poidevin]
27. Natural Reality / D. Time / 3. Parts of Time / a. Beginning of time
The present is the past/future boundary, so the first moment of time was not present [Le Poidevin]
27. Natural Reality / D. Time / 3. Parts of Time / c. Intervals
The primitive parts of time are intervals, not instants [Le Poidevin]
27. Natural Reality / D. Time / 3. Parts of Time / e. Present moment
If time is infinitely divisible, then the present must be infinitely short [Le Poidevin]
27. Natural Reality / E. Cosmology / 3. The Beginning
Scholastic authors agree that matter was created by God, out of nothing [Pasnau]
27. Natural Reality / E. Cosmology / 10. Multiverse
The multiverse is distinct time-series, as well as spaces [Le Poidevin]
28. God / A. Divine Nature / 4. Divine Contradictions
Presumably God can do anything which is logically possible [Chalmers]
28. God / A. Divine Nature / 5. God and Time
God being inside or outside of time both raise a group of difficult problems [Le Poidevin]
How could a timeless God know what time it is? So could God be both timeless and omniscient? [Le Poidevin]
29. Religion / B. Monotheistic Religion / 4. Christianity / b. Transubstantiation
Transubstantion says accidents of bread and wine don't inhere in the substance [Pasnau]
