The Causal Role of Consciousness in a Physical World

According to Papineau’s qualitative view, experiences instantiate both representational and phenomenal properties. The instantiation of phenomenal properties is people undergoing the relevant experience. In contrast, the instantiation of representational properties relies on changing relationships between the person and the environment in which the person is embedded. The upshot is that phenomenal and representational properties are only contingently related: phenomenal properties are neither identical to, nor supervene on, representational properties. In this article, the author gives a detailed criticism of Papineau’s qualitative view. Papineau’s qualitative view left unexplained the relevant causal role of consciousness in accounting for actions—assuming that a mental state only becomes conscious when it is poised to make a direct difference to what the subject believes and later remembers, how the subject reasons, what decisions the subject makes, and what rational actions the subject performs. The author argues that the same reasons that support Papineau’s complaint that it is hard to see how distal particulars and properties make their way into the realm of consciousness—namely some traditional arguments against representationalism—also show that it is hard to see how phenomenal consciousness makes its way back into the outside world in explaining the rational control of actions.
