 Henceforth, we shall often just use the term ‘realism’ to mean metaphysical realism. Opposition to realism can take many forms so there is no single theoretical view denoted by the term ‘anti-realism’. In particular, anti-realism is not Idealism, even though Idealism is its most recognised form. One approach, popular in Continental Philosophy, rejects realism on the grounds that words can only acquire their meaning intra-linguistically, through their semantic relations with other words, where these relations are grounded in our linguistic and cultural practices, rather than through referential relations to the world outside of language. This view, Anti-Representationalism as it is sometimes called, has gained traction in analytic philosophy also [See Price 2009].
