This chapter argues that if a global workspace theory of phenomenal consciousness is correct, and is fully reductive in nature, then we should stop asking questions about consciousness in nonhuman animals. But this is not because those questions are too hard to answer, but because there are no substantive facts to discover. The argument in support of this conclusion turns on the idea that while global broadcasting is all-or-nothing in the human mind, it is framed in terms that imply gradations across species. Yet our concept of phenomenal consciousness doesn’t permit mental states to be to some degree conscious. Moreover, the first-person concepts that give rise to the problem of consciousness cannot intelligibly be projected into minds significantly different from our own.
