14684 | A world is 'accessible' to another iff the first is possible according to the second [Salmon,N] |
14669 | For metaphysics, T may be the only correct system of modal logic [Salmon,N] |
14692 | System B implies that possibly-being-realized is an essential property of the world [Salmon,N] |
14667 | System B has not been justified as fallacy-free for reasoning on what might have been [Salmon,N] |
14668 | In B it seems logically possible to have both p true and p is necessarily possibly false [Salmon,N] |
14671 | What is necessary is not always necessarily necessary, so S4 is fallacious [Salmon,N] |
14686 | S5 modal logic ignores accessibility altogether [Salmon,N] |
14691 | S5 believers say that-things-might-have-been-that-way is essential to ways things might have been [Salmon,N] |
14693 | The unsatisfactory counterpart-theory allows the retention of S5 [Salmon,N] |
14670 | Metaphysical (alethic) modal logic concerns simple necessity and possibility (not physical, epistemic..) [Salmon,N] |
14678 | Any property is attached to anything in some possible world, so I am a radical anti-essentialist [Salmon,N] |
14680 | Logical possibility contains metaphysical possibility, which contains nomological possibility [Salmon,N] |
14685 | Metaphysical necessity is NOT truth in all (unrestricted) worlds; necessity comes first, and is restricted [Salmon,N] |
14690 | In the S5 account, nested modalities may be unseen, but they are still there [Salmon,N] |
14688 | Without impossible worlds, the unrestricted modality that is metaphysical has S5 logic [Salmon,N] |
14677 | Metaphysical necessity is said to be unrestricted necessity, true in every world whatsoever [Salmon,N] |
14679 | Bizarre identities are logically but not metaphysically possible, so metaphysical modality is restricted [Salmon,N] |
14681 | Logical necessity is free of constraints, and may accommodate all of S5 logic [Salmon,N] |
14676 | Nomological necessity is expressed with intransitive relations in modal semantics [Salmon,N] |
14689 | Necessity and possibility are not just necessity and possibility according to the actual world [Salmon,N] |
14674 | Impossible worlds are also ways for things to be [Salmon,N] |
14682 | Denial of impossible worlds involves two different confusions [Salmon,N] |
14687 | Without impossible worlds, how things might have been is the only way for things to be [Salmon,N] |
14683 | Possible worlds rely on what might have been, so they can' be used to define or analyse modality [Salmon,N] |
14675 | Possible worlds just have to be 'maximal', but they don't have to be consistent [Salmon,N] |
14672 | Possible worlds are maximal abstract ways that things might have been [Salmon,N] |
14673 | You can't define worlds as sets of propositions, and then define propositions using worlds [Salmon,N] |
4983 | There are no rules linking thought and behaviour, because endless other thoughts intervene [Davidson] |
3529 | Reduction is impossible because mind is holistic and brain isn't [Davidson, by Maslin] |
2307 | Anomalous monism says nothing at all about the relationship between mental and physical [Davidson, by Kim] |
5497 | Mind is outside science, because it is humanistic and partly normative [Davidson, by Lycan] |
4081 | Anomalous monism says causes are events, so the mental and physical are identical, without identical properties [Davidson, by Crane] |
2321 | If rule-following and reason are 'anomalies', does that make reductionism impossible? [Davidson, by Kim] |
3404 | Davidson claims that mental must be physical, to make mental causation possible [Davidson, by Kim] |
3405 | If mental causation is lawless, it is only possible if mental events have physical properties [Davidson, by Kim] |
16041 | Supervenience of the mental means physical changes mental, and mental changes physical [Davidson] |
6620 | Davidson sees identity as between events, not states, since they are related in causation [Davidson, by Lowe] |
3429 | Multiple realisability was worse news for physicalism than anomalous monism was [Davidson, by Kim] |
15998 | Perfect love is not in spite of imperfections; the imperfections must be loved as well [Kierkegaard] |
3524 | Causation is either between events, or between descriptions of events [Davidson, by Maslin] |
3526 | Whether an event is a causal explanation depends on how it is described [Davidson, by Maslin] |
