'Taking politics seriously: A prudential justification of political realism'

Political realists have devoted much effort to clarifying the methodological specificity of realist theorising and defending its consistency as an approach to political reasoning. Yet the question of how to justify the realist approach has not received the same attention. In this article, I offer a prudential justification of political realism. To do so, I first characterise realism as anti-moralism. I then outline three possible arguments for the realist approach by availing myself of recent inquiries into the metatheoretical basis of realism: The metaethical, the ethical and the prudential arguments. I explain that the prudential argument offers the most solid basis for political realism because it relies on the least controversial premises. Still, I delve into the metaethical and ethical arguments for two reasons: The prudential argument takes advantage of the theses defended by the rival arguments and elaborating the other arguments shows the comparative strengths of the prudential argument.
