Which beings have moral status? I argue that moral status requires some capacity for hedonic feelings of pleasure or displeasure. David Chalmers rejects this view on the grounds that it denies moral status to Vulcans, which are defined as conscious creatures with no capacity for hedonic feelings. On his more inclusive view, all conscious beings have moral status. We agree that only conscious beings have moral status, but we disagree about how to explain this. I argue that we cannot explain (...) why consciousness is necessary for moral status without denying that it is sufficient for moral status. Hence, we cannot exclude unconscious zombies without excluding conscious Vulcans too. (shrink)

The aesthetic tradition has identified as paradigmatically sublime such objects as imposing mountains and intense storms, as well as monumental art. But the tradition also acknowledges less paradigmatic cases, including sometimes mathematical structures or abstract concepts. In this paper, we argue that there is also a case for considering phenomenal consciousness – the experiential quality of subjective awareness – as a sublime phenomenon. One appreciates this, we argue, when one is struck by (fitting) awe upon contemplating (a) the perplexing existence (...) of something like phenomenal consciousness in an otherwise completely material universe and (b) the role of consciousness in injecting meaning and value in an otherwise brutally factual reality.

Many think that a specific aspect of phenomenal consciousness – valenced or affective experience – is essential to consciousness’s moral significance (valence sentientism). They hold that valenced experience is necessary for well-being, or moral status, or psychological intrinsic value (or all three). Some think that phenomenal consciousness generally is necessary for non-derivative moral significance (broad sentientism). Few think that consciousness is unnecessary for moral significance (non-necessitarianism). In this paper I consider the prospects for these views. I first consider the prospects (...) for valence sentientism in light of Vulcans, beings who are conscious but without affect or valence of any sort. I think Vulcans pressure us to accept broad sentientism. But I argue that a consideration of explanations for broad sentientism opens up possible explanations for non-necessitarianism about the moral significance of consciousness. That is, once one leans away from valence sentientism because of Vulcans, one should feel pressure to accept a view on which consciousness is not necessary for well-being, moral status, or psychological intrinsic value.

Under what conditions would an artificially intelligent system have wellbeing? Despite its clear bearing on the ethics of human interactions with artificial systems, this question has received little direct attention. Because all major theories of wellbeing hold that an individual’s welfare level is partially determined by their mental life, we begin by considering whether artificial systems have mental states. We show that a wide range of theories of mental states, when combined with leading theories of wellbeing, predict that certain existing (...) artificial systems have wellbeing. Along the way, we argue that there are good reasons to believe that artificial systems can have wellbeing even if they are not phenomenally conscious. While we do not claim to demonstrate conclusively that AI systems have wellbeing, we argue that there is a significant probability that some AI systems have or will soon have wellbeing, and that this should lead us to reassess our relationship with the intelligent systems we create.

If moral status depends on the capacity for consciousness, what kind of consciousness matters exactly? Two popular answers are that any kind of consciousness matters (Broad Sentientism), and that what matters is the capacity for pleasure and suffering (Narrow Sentientism). I argue that the broad answer is too broad, while the narrow answer is likely too narrow, as Chalmers has recently argued by appeal to ‘philosophical Vulcans’. I defend a middle position, Motivational Sentientism, on which what matters is motivating consciousness: (...) any kind of consciousness which presents its subject with reasons for action. (shrink)

There is a strong intuition that a zombie’s life is never good or bad for the zombie. What explains this? In this paper, I consider five possible explanations of the intuition that a zombie’s life is never worth living, plus the option of rejecting the intuition. I point out the considerable costs of each option, though making clear which option strikes me as least problematic.

Prudential value is the kind of value that something has when it is good for someone, in the sense that is conceptually tied to welfare or well‐being. Impersonal value is the kind of value that something has when it is good simply, absolutely, or “from the point of view of the universe.” According to the Moorean position on prudential value, the concept of prudential value can be analyzed in terms of that of impersonal value and is unintelligible if it is (...) not so analyzed. I answer some recent arguments for the Moorean position due to Kris McDaniel and Thomas Hurka, and I make a more comprehensive case than has thus far been made for rejecting that position. (shrink)

Intuitively, there is a close link between moral status and phenomenal consciousness. Taking the link seriously can serve as the basis of a proposal that appears to have a surprising number of theoretical benefits. This proposal is the moral option, according to which moral status is partly determinative of phenomenal consciousness, and phenomenal consciousness is sufficient for possession of a moral property I refer to as “moral status.” I argue for this view on the basis of its ability to shed (...) light on the distribution problem of determining which systems are phenomenally conscious. I explicate it by drawing on a theory of attributions of phenomenal consciousness, and considering its relationship to positions on the metaphysics of consciousness. I defend it against a series of objections, including three based on previous theories of the link between phenomenal consciousness and moral status. The moral option should, in my view, be a serious contender among theories of phenomenal consciousness. (shrink)

In this critical discussion, I evaluate David Chalmers’ position on the moral grounding question from his (2022) Reality +. The moral grounding question asks: in virtue of what does an entity x have moral standing? Chalmers argues for the claim that phenomenal consciousness is a necessary condition for moral standing. After a brief introduction to his book, I evaluate his position on the moral grounding question from the perspective of access consciousness as opposed to phenomenal consciousness, as well as the (...) Jain doctrine of non-violence, and the differentiation of creatures in terms of their sense capacities. (shrink)

Most philosophers think that phenomenal consciousness underlies, or at any rate makes a large contribution, to moral considerability. This paper argues that many such accounts invoke question-begging arguments. Moreover, they’re unable to explain apparent differences in moral status across and within different species. In the light of these problems, I argue that we ought to take very seriously a view according to which moral considerability is grounded in functional properties. Phenomenal consciousness may be sufficient for having a moral value, but (...) it may not be necessary, and it may contribute relatively little to our overall considerability. (shrink)
