Abstract
I argue that the hard problem of consciousness should be viewed from the perspective of the philosophy of science. In this context, the hard problem can be reformulated as a serious anomaly for the currently dominating research programme in the cognitive neurosciences. I cite empirical evidence from dream research to argue that for this research programme, consciousness is a phenomenon located inside the brain, but for whose constitution no plausible underlying constitutive mechanisms can at the moment be pointed out. Evidence from dream research demonstrates the anomaly in a particularly clear and challenging form, and the empirical facts of dreaming also demonstrate that externalist, embodied, and enactive explanations of consciousness will not be able to solve the problem.
