Abstract
Although it is, often considered a form of anti-realism, here it is argued that Bohr's complementarity viewpoint must accept entity realism based on its analysis of the causal interaction involved in observation. However, because Bohr accepts the quantum postulate he must reject the view that the goal of theory is to represent the independently existing object apart from observation. Thus he abandons the spectator account of knowledge and with it the correspondence theory of truth. In this respect his view is parallel to the positions held by Hacking, Cartwright, and Ellis.
