 (2) Donald Davidson’s (1970) anomalous monism held that (i) each mental event is identical with a physical event, but (ii) there are no psychophysical laws. Davidson accepted the view that causation involves laws and, in view of (ii), held that the laws into which mental events entered related physical properties (or, mental events under their physical descriptions). Many philosophers regarded this view as tantamount to epiphenomenalism, i.e., to the view that causation of our behavior involves only the physical properties of our parts, and that the mental properties as such have no efficacy.
