12010 | Is the meaning of 'and' given by its truth table, or by its introduction and elimination rules? [Forbes,G] |

11885 | Only individual essences will ground identities across worlds in other properties [Forbes,G, by Mackie,P] |
12014 | An individual essence is a set of essential properties which only that object can have [Forbes,G] |
12015 | Non-trivial individual essence is properties other than de dicto, or universal, or relational [Forbes,G] |
12013 | Essential properties depend on a category, and perhaps also on particular facts [Forbes,G] |
12012 | Essential properties are those without which an object could not exist [Forbes,G] |
12025 | Artefacts have fuzzy essences [Forbes,G] |
12022 | Same parts does not ensure same artefact, if those parts could constitute a different artefact [Forbes,G] |
12020 | An individual might change their sex in a world, but couldn't have differed in sex at origin [Forbes,G] |
11888 | Identities must hold because of other facts, which must be instrinsic [Forbes,G, by Mackie,P] |
12003 | De re modal formulae, unlike de dicto, are sensitive to transworld identities [Forbes,G] |
12028 | De re necessity is a form of conceptual necessity, just as de dicto necessity is [Forbes,G] |
12008 | Unlike places and times, we cannot separate possible worlds from what is true at them [Forbes,G] |
12009 | The problem with possible worlds realism is epistemological; we can't know properties of possible objects [Forbes,G] |
12007 | Possible worlds are points of logical space, rather like other times than our own [Forbes,G] |
12011 | Transworld identity concerns the limits of possibility for ordinary things [Forbes,G] |
12016 | The problem of transworld identity can be solved by individual essences [Forbes,G] |
12004 | Counterpart theory is not good at handling the logic of identity [Forbes,G] |
12021 | Haecceitism attributes to each individual a primitive identity or thisness [Forbes,G] |
12029 | We believe in thisnesses, because we reject bizarre possibilities as not being about that individual [Forbes,G] |
11141 | Modern empiricism tends to emphasise psychological connections, not semantic relations [Margolis/Laurence] |
11142 | Body-type seems to affect a mind's cognition and conceptual scheme [Margolis/Laurence] |
11121 | Language of thought has subject/predicate form and includes logical devices [Margolis/Laurence] |
11120 | Concepts are either representations, or abilities, or Fregean senses [Margolis/Laurence] |
11122 | A computer may have propositional attitudes without representations [Margolis/Laurence] |
11124 | Do mental representations just lead to a vicious regress of explanations [Margolis/Laurence] |
11123 | Maybe the concept CAT is just the ability to discriminate and infer about cats [Margolis/Laurence] |
11125 | The abilities view cannot explain the productivity of thought, or mental processes [Margolis/Laurence] |
11140 | Concept-structure explains typicality, categories, development, reference and composition [Margolis/Laurence] |
11128 | Classically, concepts give necessary and sufficient conditions for falling under them [Margolis/Laurence] |
11129 | The classical theory explains acquisition, categorization and reference [Margolis/Laurence] |
11130 | Typicality challenges the classical view; we see better fruit-prototypes in apples than in plums [Margolis/Laurence] |
11131 | It may be that our concepts (such as 'knowledge') have no definitional structure [Margolis/Laurence] |
11134 | People don't just categorise by apparent similarities [Margolis/Laurence] |
11136 | Many complex concepts obviously have no prototype [Margolis/Laurence] |
11133 | Prototype theory categorises by computing the number of shared constituents [Margolis/Laurence] |
11135 | Complex concepts have emergent properties not in the ingredient prototypes [Margolis/Laurence] |
11132 | The prototype theory is probabilistic, picking something out if it has sufficient of the properties [Margolis/Laurence] |
11137 | The theory theory of concepts says they are parts of theories, defined by their roles [Margolis/Laurence] |
11138 | The theory theory is holistic, so how can people have identical concepts? [Margolis/Laurence] |
11139 | Maybe concepts have no structure, and determined by relations to the world, not to other concepts [Margolis/Laurence] |
11146 | People can formulate new concepts which are only named later [Margolis/Laurence] |
