Irrealism is a philosophical position first advanced by Nelson Goodman in "Ways of Worldmaking",[1] encompassing epistemology, metaphysics, and aesthetics.
[2] Rather than viewing either as prior to the other, Goodman described them both as alternative "world-versions", both useful in some circumstances, but neither capable of capturing the other in an entirely satisfactory way, a point he emphasizes with examples from psychology.
[3] He goes on to extend this epistemic pluralism to all areas of knowledge, from equivalent formal systems in mathematics (sometimes it is useful to think of points as primitives, sometimes it is more useful to consider lines the primitive) to alternative schools of art (for some paintings thinking in terms of representational accuracy is the most useful way of considering them, for others it is not).
Reality is plurality - we partially create it, we must open our universes and our perceptions to all new versions that may promote the concept of human rights and expand its possibilities.
"[7] The sociologist Nikolas Rose subscribes to irrealism in his Powers of Freedom, though his irrealism differs from Goodman's in being 'technical, not psychologistic, furthering Goodman's assertions of the human mind are only capable of a limited understanding and that it is a construct built upon itself."
