Zusammenfassung:
In his A Realist Philosophy of Economics Karl Mittermaier (2023) commends the importance of distinguishing between two order of facts which he designates as ex post and ex ante facts. He argues that making this distinction allows us to identify and exploit useful ex ante facts such as structural and causal factors, which in turn can be used as an epistemic warrant for making predictions. This article scrutinises work in philosophy, economics and the social sciences where attempts are made to follow through on this strategy and make predictions underpinned by structural and causal facts. It explores points of comparison and contrasts between this work and the exposition of ex ante facts provided by Mittermaier.
