When it comes to the question of objectivity in current philosophical debates, there is a growing prominence of two opposite approaches: nominalism and realism. By absolutising intersubjectivity, the nominalist approach is moving towards the abandonment of the very notion of truth and objective reality. For its part, the realist approach insists on the category of the object-in-itself as irreducible to any kind of subjective mediation. Despite their seeming mutual exclusiveness, both approaches share a fundamental presupposition, namely, that of a neat separation between the spheres of subjectivity and objectivity as well as between fiction and truth. This collection offers a rethinking of the relationship between objectivity and fiction through engaging with a series of ‘objective fictions’, including such topics as fetishes, semblances, lies, rumours, sophistry, fantasies and conspiracy theories. It does so through engagement with modern and contemporary philosophical traditions and psychoanalytic theory, with all of these orientations being irreducible to either nominalist or realist approaches.
