Our present moral traits are unable to provide the level of large-scale co-operation necessary to deal with risks such as nuclear proliferation, drastic climate change and pandemics. In order to survive in an environment with powerful and easily available technologies, some authors claim that we need to improve our moral traits with moral enhancement. But this is prone to produce paradoxical effects, be self-reinforcing and harm personal identity. The risks of moral enhancement require the use of a safety framework; such (...) a framework should guarantee practical robustness to moral uncertainty, empirical adequacy, correct balance between dispositions, preservation of identity, and be sensitive to practical considerations such as emergent social effects. A virtue theory can meet all these desiderata. Possible frameworks incorporate them to variable degrees. The social value orientations framework is one of the most promising candidates. (shrink)

What makes someone the same person over time? There are (at least) two ways of understanding this question: A person can be the same in the sense of being very similar to how they used to be (similarity), or they can be the same in the sense of being the same individual (numerical identity). In recent years, several papers have claimed to explore the commonsense notion of numerical identity. However, we suggest here that these researchers have instead been studying similarity. (...) We develop a novel method that uses simple intuitions about objects to illustrate these two notions of “same person”, and then asks which concept applies to instances of personal change. Across 4 studies (N = 2446), we find that these previously documented intuitions are best understood as reflecting judgments about similarity, not identity (Experiments 1 and 2). We then use this method to explore the situations in which participants do perceive a change in numerical identity. We find that when a person's entire brain (Experiments 3 and 4) or soul (Experiment 4) has been replaced with that of another person, the majority of participants judge that numerical identity has changed. However, we also note that a substantial minority of participants denied that identity had changed, opening new questions about the role of the body in intuitive judgments of personal identity.

A prominent view on personal identity over time, Jeff McMahan’s ‘Embodied Mind Account’ (2002) holds that we cease to exist only once our brains can no longer sustain the basic capacity to uphold consciousness. One of the many implications of this view on identity persistence is that we continue to exist throughout even the most severe cases of dementia, until our consciousness irreversibly shuts down. In this paper, I argue that, while the most convincing of prominent accounts of personal identity (...) over time, McMahan’s account faces serious challenges in explanatory power of dementias and related neurodegenerative conditions. Particularly, this becomes visible in the face of emerging methods for neural tissue regeneration, and the possibility of ‘re-emerging patients’. I argue that medical professionals’ neglecting qualitative aspects of identity risks resulting in grave misunderstandings in decision-making processes, and ethically objectionable outcomes in future practices. Finally, I propose revisions which could potentially salvage the great benefits that Embodied Mind Theory still can bring to the field of dementia care in terms of understanding life, death, and identity across the lifespan.

Fabiano argues that virtue theory offers the best “safety framework” for mitigating the risks of moral enhancement (1). He advances five desiderata for an ideal safety framework and then explains how virtue theory satisfies each. Among these desiderata is the “preservation of identity” (1). Fabiano argues that moral enhancement can safely preserve personal identity when carried out within the framework of virtue theory. We suggest Fabiano's argument for this conclusion falls short, since contra Fabiano’s claim, enhancing virtues may not preserve—and (...) could even damage—personal identity. We draw on three sources of evidence: 1) virtue theory scholarship that argues for the importance of habituation for virtue formation, 2) Focquaert and Schermer’s (2015) distinction between active and passive enhancement and attendant endorsement of more active paths to virtue enhancement, and 3) empirical research suggesting that technologies which support moral enhancements may have damaging effects on personal identity.

The Centred View offers an account of the connection between imagination and possibility that combines the centred world framework with some allegedly appealing intuitions regarding our persistence over time. In particular, Dilip Ninan suggests that the Centred View has the theoretical advantage of respecting our intuitions about cases of personal identity in certain imaginative scenarios while also being compatible with physicalism. Unfortunately, the Centred View faces a series of serious objections and should ultimately be rejected.

Deliberative analysis enables us to weigh features, simulate futures, and arrive at good, tractable decisions. So why do we so often eschew deliberation, and instead rely on more intuitive, gut responses? We propose that intuition might be prescribed for some decisions because people’s folk theory of decision-making accords a special role to authenticity, which is associated with intuitive choice. Five pre-registered experiments find evidence in favor of this claim. In Experiment 1 (N = 654), we show that participants prescribe intuition (...) and deliberation as a basis for decisions differentially across domains, and that these prescriptions predict reported choice. In Experiment 2 (N = 555), we find that choosing intuitively vs. deliberately leads to different inferences concerning the decision-maker’s commitment and authenticity—with only inferences about the decision-maker’s authenticity showing variation across domains that matches that observed for the prescription of intuition in Experiment 1. In Experiment 3 (N = 631), we replicate our prior results and rule out plausible confounds. Finally, in Experiment 4 (N = 177) and Experiment 5 (N = 526), we find that an experimental manipulation of the importance of authenticity affects the prescribed role for intuition as well as the endorsement of expert human or algorithmic advice. These effects hold beyond previously recognized influences on intuitive vs. deliberative choice, such as computational costs, presumed reliability, objectivity, complexity, and expertise. (shrink)

Most contemporary accounts of moral responsibility take desert to play a central role in the nature of moral responsibility. It is also assumed that desert is a backward-looking concept that is not directly derivable from any forward-looking or consequentialist considerations, such as whether blaming an agent would deter the agent from performing similar bad actions in the future. When determining which account of moral responsibility is correct, proponents of desert-based accounts often take intuitions about cases to provide evidence either in (...) favor of or against a proposed theory. In this paper, I discuss two experiments that test whether folk intuitions accord with what desert-based accounts would predict. Results suggest that moral responsibility intuitions are sensitive to forward-looking considerations, thus posing a problem for desert-based accounts of moral responsibility. If appealing to intuitions about cases is a valid method of discovering the nature of moral responsibility and desert, it seems either desert is not entirely backward-looking or moral responsibility is not exclusively desert-based. These experimental results also suggest that consequentialist accounts of moral responsibility, which have largely been abandoned due to their counterintuitive nature, are perhaps not so counterintuitive after all.

What does it mean to become older? This question cannot be answered by biology or sociology alone but must be addressed by studying how aging appears to aging persons and to others who encounter them. The paper presents the outline of such a phenomenological analysis of aging. In contrast to a problematic tendency to reduce phenomenology to the study of first-person experience, it is suggested that aging should be understood as a complex process comprising of both subjective and objective (mental, (...) social and biological) elements, and as partly transcendent to experience, that is, not completely transparent to the aging person. In this it resembles physical and other “transcendent” objects as described by early phenomenologists like Husserl. It is further shown how Marcel Proust’s elaborate description of aging in the last volume of his Remembrance of Time Past can support and contribute to such an analysis, and how it is supported or at least compatible with findings from contemporary gerontology and cognitive psychology.
