The essay discusses Donald Davidson's concept of anomalous monism in the framework of Husserlian phenomenology. It develops in four stages. Section 1 is devoted to a critical presentation of the argument for anomalous monism. Section 2 succinctly examines those Husserlian notions that best provide the ground for a discussion parallel to Davidson's. In Sect. 3, the aporetic status of "mental causation" is analyzed by providing a genetic-phenomenological account of efficient causation. Section href="#Sec4">4 draws some general conclusions concerning the kind of efficaciousness that must be attributed to consciousness and discusses the sense in which anomalous monism can be defended in a phenomenological framework, but not in a naturalistic one.
