2781 | Realism says that most perceived objects exist, and have some of their perceived properties [Dancy,J] |
Full Idea: Realism in the theory of perception is that objects we perceive usually do exist, and retain some at least of the properties we perceive them as having. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 10.2) |
5736 | No sort of plain language or levels of logic can express modal facts properly [Melia] |
Full Idea: Some philosophers say that modal facts cannot be expressed either by name/predicate language, or by first-order predicate calculus, or even by second-order logic. | |
From: Joseph Melia (Modality [2003], Ch.2) | |
A reaction: If 'possible' were a predicate, none of this paraphernalia would be needed. If possible worlds are accepted, then the quantifiers of first-order predicate calculus will do the job. If neither of these will do, there seems to be a problem. |
5735 | Maybe names and predicates can capture any fact [Melia] |
Full Idea: Some philosophers think that any fact can be captured in a language containing only names and predicates. | |
From: Joseph Melia (Modality [2003], Ch.2) | |
A reaction: The problem case Melia is discussing is modal facts, such as 'x is possible'. It is hard to see how 'possible' could be an ordinary predicate, but then McGinn claims that 'existence' is, and that there are some predicates with unusual characters. |
