Abstract

One of the most interesting forms of antirealism developed in recent years is the irrealism of Nelson Goodman. According to that position, the widely held belief that there is one real world and one way the world is, and that the aim of our inquiry is to provide a true description of that world, is mistaken. We should not envisage our cognitive activity as involving recognition and description of the unique structure of the world, but rather as engaged in construction of various world versions. It should also be admitted that in this process we, in some important and nontrivial sense, make worlds corresponding to those versions. That is to say, this version of irrealism combines a constructionalist account of our knowledge with radical ontological pluralism. Such a view certainly leads to a relativism of some sort, but Goodman thinks that this is not the relativism of “anything goes” type, since construction and acceptance of world versions is constrained by some standards of rightness.
