In his new foreword to this edition, Hilary Putnam forcefully rejects these nativist claims.

CONTRARY TO GOODMAN’S VIEW, A CLEAR DISTINCTION CAN BE MADE BETWEEN QUALITATIVE AND POSITIONAL PREDICATES. HENCE WE CAN EXPLAIN THAT WE OUGHT TO PROJECT ’GREEN’ RATHER THAN ’GRUE’ BECAUSE THE LATTER IS A POSITIONAL PREDICATE, RATHER THAN BECAUSE THE LATTER IS LESS WELL ENTRENCHED. A PREDICATE IS POSITIONAL IF, TO FIND OUT AS CERTAINLY AS WE CAN WHETHER IT APPLIES TO AN OBJECT, WE HAVE TO FIND OUT THE LATTER’S SPATIO-TEMPORAL LOCATION.

Discussion of Wittgenstein's philosophy has suffered from a scarcity of commentators who understand his work well enough to explain it in their own words. Apart from certain notable exceptions, all too many advocates and critics alike have tended merely to repeat slogans, with approval or ridicule as the case may be. The result has been an unusual degree of polarization and acrimony—some philosophers abandoning normal critical standards, falling under the spell and becoming fanatical supporters; and others taking an equally extreme (...) opposite view, deriding the absence of analytic technique, and refusing to see anything of value in Wittgenstein's work.

Professor Goodman first presented his "new riddle of induction" in 1946 but it was mainly the more elaborated version published in his Fact, Fiction and Forecast in 1955 that has captured the attention of philosophers. Since then, numerous attempts to solve his "paradox of grue" appeared in press; none of them, however, proved to be wholly satisfactory. In this paper I want to present a solution to this 30-years old puzzle. In the first section I shall try to show that (...) my solution, which is based on a Gedankenexperiment, is immune to the objections leveled against previous attempts. In light of this solution I shall re-examine the status of the paradox and show that in order to preserve the meaningfulness of the paradox some type of Platonic framework for the theory of meaning should have to be assumed. In the last section I shall discuss a proposed solution to the paradox using counterfactual claims. I will show that despite the similarity between counterfactuals and thought-experiments, the counterfactual approach does not lead to a satisfactory solution. (shrink)
