14912 | There is no test for metaphysics, except devising alternative theories [Ladyman/Ross] |

14904 | Metaphysics builds consilience networks across science [Ladyman/Ross] |
14907 | Progress in metaphysics must be tied to progress in science [Ladyman/Ross] |
14908 | Metaphysics must involve at least two scientific hypotheses, one fundamental, and add to explanation [Ladyman/Ross] |

14940 | Cutting-edge physics has little to offer metaphysics [Ladyman/Ross] |
14945 | The aim of metaphysics is to unite the special sciences with physics [Ladyman/Ross] |
15003 | It seems unlikely that the way we speak will give insights into the universe [Sider] |
14898 | Modern metaphysics pursues aesthetic criteria like story-writing, and abandons scientific truth [Ladyman/Ross] |
14986 | Conceptual analysts trust particular intuitions much more than general ones [Sider] |
14899 | Why think that conceptual analysis reveals reality, rather than just how people think? [Ladyman/Ross] |

14905 | The supremacy of science rests on its iterated error filters [Ladyman/Ross] |
14897 | We should abandon intuitions, especially that the world is made of little things, and made of something [Ladyman/Ross] |
15015 | It seems possible for a correct definition to be factually incorrect, as in defining 'contact' [Sider] |
14981 | Philosophical concepts are rarely defined, and are not understood by means of definitions [Sider] |
14992 | We don't care about plain truth, but truth in joint-carving terms [Sider] |

14980 | There is a real issue over what is the 'correct' logic [Sider] |
15000 | 'It is raining' and 'it is not raining' can't be legislated, so we can't legislate 'p or ¬p' [Sider] |
15020 | Classical logic is good for mathematics and science, but less good for natural language [Sider] |
15029 | Modal accounts of logical consequence are simple necessity, or essential use of logical words [Sider] |
14943 | Maybe mathematical logic rests on information-processing [Ladyman/Ross] |
15019 | Define logical constants by role in proofs, or as fixed in meaning, or as topic-neutral [Sider] |

15017 | Supervenience is a modal connection [Sider] |
14941 | We say there is no fundamental level to ontology, and reality is just patterns [Ladyman/Ross] |
15008 | Is fundamentality in whole propositions (and holistic), or in concepts (and atomic)? [Sider] |
15013 | Tables and chairs have fundamental existence, but not fundamental natures [Sider] |
10493 | If concrete is spatio-temporal and causal, and abstract isn't, the distinction doesn't suit physics [Ladyman/Ross] |
14934 | Concrete and abstract are too crude for modern physics [Ladyman/Ross] |
15014 | Unlike things, stuff obeys unrestricted composition and mereological essentialism [Sider] |
14909 | Physicalism is 'part-whole' (all parts are physical), or 'supervenience/levels' (dependence on physical) [Ladyman/Ross] |

14983 | Accept the ontology of your best theory - and also that it carves nature at the joints [Sider] |
14926 | Relations without relata must be treated as universals, with their own formal properties [Ladyman/Ross] |
14929 | A belief in relations must be a belief in things that are related [Ladyman/Ross] |
14925 | The normal assumption is that relations depend on properties of the relata [Ladyman/Ross] |
14931 | That there are existent structures not made of entities is no stranger than the theory of universals [Ladyman/Ross] |
14978 | A property is intrinsic if an object alone in the world can instantiate it [Sider] |
14932 | Causal essentialism says properties are nothing but causal relations [Ladyman/Ross] |
14995 | Predicates can be 'sparse' if there is a universal, or if there is a natural property or relation [Sider] |
14920 | If science captures the modal structure of things, that explains why its predictions work [Ladyman/Ross] |
14952 | Things are constructs for tracking patterns (and not linguistic, because animals do it) [Ladyman/Ross] |
14950 | Maybe individuation can be explained by thermodynamic depth [Ladyman/Ross] |
14927 | Physics seems to imply that we must give up self-subsistent individuals [Ladyman/Ross] |
14944 | There is no single view of individuals, because different sciences operate on different scales [Ladyman/Ross] |
14946 | There are no cats in quantum theory, and no mountains in astrophysics [Ladyman/Ross] |
14928 | Things are abstractions from structures [Ladyman/Ross] |
14892 | The idea of composition, that parts of the world are 'made of' something, is no longer helpful [Ladyman/Ross] |
14949 | A sum of things is not a whole if the whole does not support some new generalisation [Ladyman/Ross] |

15030 | Humeans say that we decide what is necessary [Sider] |
15031 | Modal terms in English are entirely contextual, with no modality outside the language [Sider] |

15028 | Conventionalism doesn't seem to apply to examples of the necessary a posteriori [Sider] |
15033 | Humeans says mathematics and logic are necessary because that is how our concept of necessity works [Sider] |

14988 | A theory which doesn't fit nature is unexplanatory, even if it is true [Sider] |
14922 | The Ramsey sentence describes theoretical entities; it skips reference, but doesn't eliminate it [Ladyman/Ross] |
14982 | If I used Ramsey sentences to eliminate fundamentality from my theory, that would be a real loss [Sider] |
14921 | The Ramsey-sentence approach preserves observations, but eliminates unobservables [Ladyman/Ross] |
14953 | Induction is reasoning from the observed to the unobserved [Ladyman/Ross] |
14914 | Inductive defences of induction may be rule-circular, but not viciously premise-circular [Ladyman/Ross] |

16383 | Puzzled Pierre has two mental files about the same object [Recanati on Kripke] |
14999 | Prior to conventions, not all green things were green? [Sider] |
14998 | Conventions are contingent and analytic truths are necessary, so that isn't their explanation [Sider] |
15016 | Analyticity has lost its traditional role, which relied on truth by convention [Sider] |
14956 | Explanation by kinds and by clusters of properties just express the stability of reality [Ladyman/Ross] |
14957 | There is nothing more to a natural kind than a real pattern in nature [Ladyman/Ross] |
14954 | Causation is found in the special sciences, but may have no role in fundamental physics [Ladyman/Ross] |
14902 | Science may have uninstantiated laws, inferred from approaching some unrealised limit [Ladyman/Ross] |

14938 | A fixed foliation theory of quantum gravity could make presentism possible [Ladyman/Ross] |
