| 9065 | S5 collapses iterated modalities (◊□P→□P, and ◊◊P→◊P) [Keefe/Smith] |
| 17867 | If a concept is not compact, it will not be presentable to finite minds [Almog] |
| 17877 | The number series is primitive, not the result of some set theoretic axioms [Almog] |
| 9064 | Objects such as a cloud or Mount Everest seem to have fuzzy boundaries in nature [Keefe/Smith] |
| 9044 | If someone is borderline tall, no further information is likely to resolve the question [Keefe/Smith] |
| 9048 | The simplest approach, that vagueness is just ignorance, retains classical logic and semantics [Keefe/Smith] |
| 9055 | The epistemic view of vagueness must explain why we don't know the predicate boundary [Keefe/Smith] |
| 9049 | Supervaluationism keeps true-or-false where precision can be produced, but not otherwise [Keefe/Smith] |
| 9056 | Vague statements lack truth value if attempts to make them precise fail [Keefe/Smith] |
| 9058 | Some of the principles of classical logic still fail with supervaluationism [Keefe/Smith] |
| 9059 | The semantics of supervaluation (e.g. disjunction and quantification) is not classical [Keefe/Smith] |
| 9060 | Supervaluation misunderstands vagueness, treating it as a failure to make things precise [Keefe/Smith] |
| 9050 | A third truth-value at borderlines might be 'indeterminate', or a value somewhere between 0 and 1 [Keefe/Smith] |
| 9061 | People can't be placed in a precise order according to how 'nice' they are [Keefe/Smith] |
| 9062 | If truth-values for vagueness range from 0 to 1, there must be someone who is 'completely tall' [Keefe/Smith] |
| 9063 | How do we decide if my coat is red to degree 0.322 or 0.321? [Keefe/Smith] |
| 9045 | Vague predicates involve uncertain properties, uncertain objects, and paradoxes of gradual change [Keefe/Smith] |
| 9047 | Many vague predicates are multi-dimensional; 'big' involves height and volume; heaps include arrangement [Keefe/Smith] |
| 9053 | If there is a precise borderline area, that is not a case of vagueness [Keefe/Smith] |
| 17871 | Fregean meanings are analogous to conceptual essence, defining a kind [Almog] |
| 17866 | Essential definition aims at existence conditions and structural truths [Almog] |
| 17868 | Surface accounts aren't exhaustive as they always allow unintended twin cases [Almog] |
| 17872 | Definitionalists rely on snapshot-concepts, instead of on the real processes [Almog] |
| 17870 | Alien 'tigers' can't be tigers if they are not related to our tigers [Almog] |
| 17869 | Kripke and Putnam offer an intermediary between real and nominal essences [Almog] |
| 17876 | Individual essences are just cobbled together classificatory predicates [Almog] |
| 17873 | Water must be related to water, just as tigers must be related to tigers [Almog] |
| 7903 | The six perfections are giving, morality, patience, vigour, meditation, and wisdom [Nagarjuna] |
| 17864 | Defining an essence comes no where near giving a thing's nature [Almog] |
| 17863 | Essences promise to reveal reality, but actually drive us away from it [Almog] |
