Grue, philosophy: Artificial predicate in a thought experiment by Nelson Goodman (N. Goodman, Fact, Fiction and Forecast, Indianapolis, 1965) to illustrate his "New riddle of induction". An object x is grue iff x has been observed before time t and is green or has been observed after t and is blue, the time t being in the future. The problem of uncertainty as to whether something is green or grue arises because the set of green objects is a subset of the set of grue objects. See also induction, projectability, predicates._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

R. Carnap on Grue - Dictionary of Arguments
IV 31 Grue /CarnapVsGoodman: "red", etc. are purely qualitative predicates; ’grue’, etc. are positional predicates. GoodmanvsCarnap: the distinction qualitative/positional is relative to a perspective on a respective base language. This could also include gred/reen as basic predicates, then "red" and "green" would have to be interpreted in relation to a time. IV 32 Then the attributions "qualitative"/"positional" was reversed. There is no perceptible color change: who understands "green" in the sense of "gred" understands understands "color" in the sense of "blolor": things of equal blolor are those which are gred etc. See more authors on >Grueness._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
