13734 | Modern Quinean metaphysics is about what exists, but Aristotelian metaphysics asks about grounding [Schaffer,J] |
13751 | If you tore the metaphysics out of philosophy, the whole enterprise would collapse [Schaffer,J] |
14600 | Analysis aims at secure necessary and sufficient conditions [Schaffer,J] |
13743 | We should not multiply basic entities, but we can have as many derivative entities as we like [Schaffer,J] |
14603 | 'Reification' occurs if we mistake a concept for a thing [Schaffer,J] |
14713 | Truth in a scenario is the negation in that scenario being a priori incoherent [Chalmers] |
14607 | T adds □p→p for reflexivity, and is ideal for modeling lawhood [Schaffer,J] |
10373 | Logical form can't dictate metaphysics, as it may propose an undesirable property [Schaffer,J] |
13741 | If 'there are red roses' implies 'there are roses', then 'there are prime numbers' implies 'there are numbers' [Schaffer,J] |
14604 | If a notion is ontologically basic, it should be needed in our best attempt at science [Schaffer,J] |
13748 | Grounding is unanalysable and primitive, and is the basic structuring concept in metaphysics [Schaffer,J] |
17306 | If ground is transitive and irreflexive, it has a strict partial ordering, giving structure [Schaffer,J] |
17304 | As causation links across time, grounding links the world across levels [Schaffer,J] |
14599 | Three types of reduction: Theoretical (of terms), Definitional (of concepts), Ontological (of reality) [Schaffer,J] |
2392 | Properties supervene if you can't have one without the other [Chalmers] |
13747 | Supervenience is just modal correlation [Schaffer,J] |
2393 | Logical supervenience is when one set of properties must be accompanied by another set [Chalmers] |

14601 | Individuation aims to count entities, by saying when there is one [Schaffer,J] |
14082 | No sortal could ever exactly pin down which set of particles count as this 'cup' [Schaffer,J] |
13742 | There exist heaps with no integral unity, so we should accept arbitrary composites in the same way [Schaffer,J] |
13752 | The notion of 'grounding' can explain integrated wholes in a way that mere aggregates can't [Schaffer,J] |
14081 | Identities can be true despite indeterminate reference, if true under all interpretations [Schaffer,J] |
16425 | Metaphysical necessity is a bizarre, brute and inexplicable constraint on possibilities [Chalmers] |
16424 | Strong metaphysical necessity allows fewer possible worlds than logical necessity [Chalmers] |
16426 | How can we know the metaphysical impossibilities; the a posteriori only concerns this world [Chalmers] |
13956 | Kripke is often taken to be challenging a priori insights into necessity [Chalmers] |
13963 | Maybe logical possibility does imply conceivability - by an ideal mind [Chalmers] |
16473 | Modal Rationalism: conceivability gives a priori access to modal truths [Chalmers, by Stalnaker] |
19258 | Evaluate primary possibility from some world, and secondary possibility from this world [Chalmers, by Vaidya] |

2390 | We attribute beliefs to people in order to explain their behaviour [Chalmers] |
13740 | 'Moorean certainties' are more credible than any sceptical argument [Schaffer,J] |
14712 | A sentence is a priori if no possible way the world might actually be could make it false [Chalmers] |
2397 | 'Perception' means either an action or a mental state [Chalmers] |
2422 | The structure of the retina has already simplified the colour information which hits it [Chalmers] |
17308 | Explaining 'Adam ate the apple' depends on emphasis, and thus implies a contrast [Schaffer,J] |
20653 | Six reduction levels: groups, lives, cells, molecules, atoms, particles [Putnam/Oppenheim, by Watson] |
2396 | Reductive explanation is not the be-all and the end-all of explanation [Chalmers] |
2426 | Why are minds homogeneous and brains fine-grained? [Chalmers] |
2391 | Can we be aware but not conscious? [Chalmers] |
2412 | Can we explain behaviour without consciousness? [Chalmers] |
2386 | Hard Problem: why brains experience things [Chalmers] |

2417 | Does consciousness arise from fine-grained non-reductive functional organisation? [Chalmers] |
2428 | Maybe the whole Chinese Room understands Chinese, though the person doesn't [Chalmers] |
2418 | The Chinese Mind doesn't seem conscious, but then nor do brains from outside [Chalmers] |
2406 | H2O causes liquidity, but no one is a dualist about that [Chalmers] |
2405 | Perhaps consciousness is physically based, but not logically required by that base [Chalmers] |

14708 | Rationalist 2D semantics posits necessary relations between meaning, apriority, and possibility [Chalmers, by Schroeter] |
13958 | The 'primary intension' is non-empirical, and fixes extensions based on the actual-world reference [Chalmers] |
2399 | Meaning has split into primary ("watery stuff"), and secondary counterfactual meaning ("H2O") [Chalmers] |
13959 | The 'secondary intension' is determined by rigidifying (as H2O) the 'water' picked out in the actual world [Chalmers] |
13957 | Primary and secondary intensions are the a priori (actual) and a posteriori (counterfactual) aspects of meaning [Chalmers] |
13961 | We have 'primary' truth-conditions for the actual world, and derived 'secondary' ones for counterfactual worlds [Chalmers] |
14739 | 'Water' is two-dimensionally inconstant, with different intensions in different worlds [Chalmers, by Sider] |
13962 | Two-dimensional semantics gives a 'primary' and 'secondary' proposition for each statement [Chalmers] |

17305 | I take what is fundamental to be the whole spatiotemporal manifold and its fields [Schaffer,J] |
10359 | In causation there are three problems of relata, and three metaphysical problems [Schaffer,J] |
10372 | Causation may not be transitive; the last event may follow from the first, but not be caused by it [Schaffer,J] |
10374 | There are at least ten theories about causal connections [Schaffer,J] |
17307 | Nowadays causation is usually understood in terms of equations and variable ranges [Schaffer,J] |
10366 | Causation transcends nature, because absences can cause things [Schaffer,J] |
10377 | Causation may not be a process, if a crucial part of the process is 'disconnected' [Schaffer,J] |
10378 | A causal process needs to be connected to the effect in the right way [Schaffer,J] |
10382 | Causation can't be a process, because a process needs causation as a primitive [Schaffer,J] |
10375 | At least four rivals have challenged the view that causal direction is time direction [Schaffer,J] |
10389 | Causal order must be temporal, or else causes could be blocked, and time couldn't be explained [Schaffer,J] |
10390 | Causal order is not temporal, because of time travel, and simultanous, joint or backward causes [Schaffer,J] |
10380 | Causation is primitive; it is too intractable and central to be reduced; all explanations require it [Schaffer,J] |
10385 | If causation is just observables, or part of common sense, or vacuous, it can't be primitive [Schaffer,J] |
10388 | Causation is utterly essential for numerous philosophical explanations [Schaffer,J] |
10387 | The notion of causation allows understanding of science, without appearing in equations [Schaffer,J] |
10384 | If two different causes are possible in one set of circumstances, causation is primitive [Schaffer,J] |
10386 | If causation is primitive, it can be experienced in ourselves, or inferred as best explanation [Schaffer,J] |
10361 | Events are fairly course-grained (just saying 'hello'), unlike facts (like saying 'hello' loudly) [Schaffer,J] |
10360 | Causal relata are events - or facts, features, tropes, states, situations or aspects [Schaffer,J] |
10362 | One may defend three or four causal relata, as in 'c causes e rather than e*' [Schaffer,J] |
10368 | If causal relata must be in nature and fine-grained, neither facts nor events will do [Schaffer,J] |
10383 | The relata of causation (such as events) need properties as explanation, which need causation! [Schaffer,J] |
10393 | Our selection of 'the' cause is very predictable, so must have a basis [Schaffer,J] |
10394 | Selecting 'the' cause must have a basis; there is no causation without such a selection [Schaffer,J] |
10376 | The actual cause may make an event less likely than a possible more effective cause [Schaffer,J] |
10381 | All four probability versions of causation may need causation to be primitive [Schaffer,J] |
16427 | Presumably God can do anything which is logically possible [Chalmers] |
