 It is commonly supposed that logical empiricism and scientific realism are systematically at odds. However, Feigl’s diverse contributions to the scientific realism debate just suggest the opposite: Influenced by the early ‘critical’ realism of his teacher Schlick, Feigl (like Reichenbach and Eino Kaila) argued in terms of a reconciliation of both positions, that is, he attempted to combine logical empiricist methods with a scientific realist account of theoretically postulated entities (see, in this connection, also Neuber 2012, esp. pp. 45–51, and especially Neuber 2018b, ch. 5).
