Comment: In this paper, the author addresses the so-called "explanatory gap". In a nutshell, the "explanatory gap" refers to the existing difficulty of explaining consciousness in physical terms. The author considers Chalmers's argument which aims to show that there is a metaphysical gap. She argues that the existence of a metaphysical gap does not entail the existence of an explanatory gap, thereby failing to prevent scientists from discovering the nature of consciousness. Good as background reading on the topic of consciousness, its nature, and on whether we can explain in physicalist terms. The first half of the paper is particularly useful, as the author provides a survey of different theories regarding the link between consciousness and the neurological system.
