Illusionism is a revisionary view of consciousness, which denies the existence of the phenomenal properties traditionally thought to render experience conscious. The view has theoretical attractions, but some think it also has objectionable ethical implications. They take illusionists to be denying the existence of consciousness itself, or at least of the thing that gives consciousness its ethical value, and thus as undermining our established ethical attitudes. This article responds to this objection. I argue that, properly understood, illusionism neither denies the (...) existence of consciousness nor entails that consciousness does not ground ethical value. It merely offers a different account of what consciousness is and why it grounds ethical value. The article goes on to argue that the theoretical revision proposed by illusionists does have some indirect implications for our ethical attitudes but that these are wholly attractive and progressive ones. The illusionist perspective on consciousness promises to make ethical decision making easier and to extend the scope of our ethical concern. Illusionism is good news. (shrink)

In light of recent breakneck pace in machine learning, questions about whether near-future artificial systems might be conscious and possess moral status are increasingly pressing. This paper argues that as matters stand these debates lack any clear criteria for resolution via the science of consciousness. Instead, insofar as they are settled at all, it is likely to be via shifts in public attitudes brought about by the increasingly close relationships between humans and AI users. Section 1 of the paper I (...) briefly lays out the current state of the science of consciousness and its limitations insofar as these pertain to machine consciousness, and claims that there are no obvious consensus frameworks to inform public opinion on AI consciousness. Section 2 examines the rise of conversational chatbots or Social AI, and argues that in many cases, these elicit strong and sincere attributions of consciousness, mentality, and moral status from users, a trend likely to become more widespread. Section 3 presents an inconsistent triad for theories that attempt to link consciousness, behaviour, and moral status, noting that the trends in Social AI systems will likely make the inconsistency of these three premises more pressing. Finally, Section 4 presents some limited suggestions for how consciousness and AI research communities should respond to the gap between expert opinion and folk judgment. (shrink)

The marker approach is taken as best practice for answering the distribution question: Which animals are conscious? However, the methodology can be used to increase confidence in animals many presume to be unconscious, including C. elegans, leading to a trilemma: accept the worms as conscious; reject the specific markers; or reject the marker methodology for answering the distribution question. I defend the third option and argue that answering the distribution question requires a secure theory of consciousness. Accepting the hypothesis all (...) animals are conscious will promote research leading to secure theory, which is needed to create reliable consciousness tests for animals and AIs. Rather than asking the distribution question, we should shift to the dimensions question: How are animals conscious? (shrink)

Peter Carruthers has recently argued for a surprising conditional: if a global workspace theory of phenomenal consciousness is both correct and fully reductive, then there are no substantive facts to discover about phenomenal consciousness in nonhuman animals. I present two problems for this conditional. First, it rests on an odd double-standard about the ordinary concept of phenomenal consciousness: its intuitive non-gradability is taken to be unchallengeable by future scientific developments, whereas its intuitive determinacy is predicted to fall by the wayside. (...) Second, it relies on dismissing, prematurely, the live empirical possibility that phenomenal consciousness may be linked to a core global broadcast mechanism that is shared by a wide range of animals. Future developments in the science of consciousness may lead us to reconsider the non-gradability of phenomenal consciousness, but they are unlikely to lead us to accept that there are no facts to discover outside the paradigm case of a healthy adult human.

A new research programme conceives of consciousness as a natural kind. One proposed virtue of this approach is that it can help resolve the methodological puzzle of consciousness, which involves distinguishing consciousness from cognitive access. The present article raises a novel problem for this approach. The problem is rooted in the fact that there may be episodes of conscious experience that have not been classified as such. I argue that conceiving of consciousness as a natural kind cannot distinguish consciousness from (...) cognitive access. (shrink)
