The pursuit of artificial consciousness requires conceptual clarity to navigate its theoretical and empirical challenges. This paper introduces a composite, multilevel, and multidimensional model of consciousness as a heuristic framework to guide research in this field. Consciousness is treated as a complex phenomenon, with distinct constituents and dimensions that can be operationalized for study and for evaluating their replication. We argue that this model provides a balanced approach to artificial consciousness research by avoiding binary thinking (e.g., conscious vs. non-conscious) and (...) offering a structured basis for testable hypotheses. To illustrate its utility, we focus on "awareness" as a case study, demonstrating how specific dimensions of consciousness can be pragmatically analyzed and targeted for potential artificial instantiation. By breaking down the conceptual intricacies of consciousness and aligning them with practical research goals, this paper lays the groundwork for a robust strategy to advance the scientific and technical understanding of artificial consciousness.

Psychedelics require cross-cultural, interdisciplinary study, and we were happy to see a contribution from the field of medical anthropology. Such a study holds the promise of characterizing the ways in which psychedelics are situated in contemporary societies, both within and beyond research and clinical contexts. Here, we offer some friendly criticism of the target article by Noorani while also highlighting various points of agreement and looking ahead to future research in this field.Noorani’s article is structured around an organizing theme of (...) “containment.” The term is not formally defined, but functions more as a poetic metaphor, allowing the author to explore various ways in which psychedelics...

In a recent study, Lantian and colleagues (2024) measured public attitudestoward the use of ‘love drugs’ as introduced through the work of Earp,Savulescu, and their collaborators. Use of a “revolutionary pill” (described as“100% reliable”) to bring about love is seen as less morally acceptable thanpsychological therapy toward the same end, and this is partly explained byperceptions that the pill-induced love is less authentic. However, the “pill” inquestion bears little resemblance to the real-world uses of love drugs discussedby Earp (...) and Savulescu, such as MDMA-assisted couples therapy. In this partialreplication and extension study, we show that more ecologically valid ‘lovedrugs’ scenarios lead to much higher ratings of moral acceptability and perceived authenticity of the resulting love.

Evidence suggests that psychedelics bring about their therapeutic outcomes in part through the subjective or qualitative effects they engender and how the individual interprets the resulting experiences. However, psychedelics are contraindicated for individuals who have been diagnosed with certain mental illnesses, on the grounds that these subjective effects may be disturbing or otherwise counter-therapeutic. Substantial resources are therefore currently being devoted to creating psychedelic substances that produce many of the same biological changes as psychedelics, but without their characteristic subjective effects. (...) In this article, we consider ethical issues arising from the prospect of such potential “nonsubjective” psychedelics. We are broadly supportive of efforts to produce such substances for both scientific and clinical reasons. However, we argue that such nonsubjective psychedelics should be reserved for those special cases in which the subjective effects of psychedelics are specifically contraindicated, whereas classic psychedelics that affect subjective experience should be considered the default and standard of care. After reviewing evidence regarding the subjective effects of psychedelics, we raise a number of ethical concerns around the prospect of withholding such typically positive, meaningful, and therapeutic experiences from most patients.

The psychedelic psilocybin has shown promise both as treatment for psychiatric conditions and as a means of improving well-being in healthy individuals. In some jurisdictions (e.g., Oregon, USA), psilocybin use for both purposes is or will soon be allowed and yet, public attitudes toward this shift are understudied. We asked a nationally representative sample of 795 US Americans to evaluate the moral status of psilocybin use in an appropriately licensed setting for either treatment of a psychiatric condition or well-being enhancement. (...) Showing strong bipartisan support, participants rated the individual’s decision as morally positive in both contexts. These results can inform effective policy-making decisions around supervised psilocybin use, given robust public attitudes as elicited in the context of an innovative regulatory model. We did not explore attitudes to psilocybin use in unsupervised or non-licensed community or social settings. (shrink)

Endosex, in contrast to intersex, refers to innate physical sex characteristics judged to fall within the broad range of what is considered normative or typical for ‘binary’ female or male bodies by the medical field, or to persons with such characteristics1 (p. 437). In this short contribution, we explain the origins and increasing use of this little-known term and discuss its practical and ethical relevance to medicine as well as to scholarship from a range of disciplines concerned with individuals’ sexed (...) embodiment. There is growing awareness in many quarters of the term intersex— used within some discourses to refer to clusters of bodily attributes (as in ‘intersex traits’, also termed differences of sex development or variations of sex characteristics)1 or more broadly to persons (as in ‘intersex persons’) whose bodily attributes differ from the dominant clinical, biological, or legal paradigms that categorise and differentiate female and male bodies. Intersex traits have historically been stigmatised as monstrous, morbid or tragic, justifying surgical and hormonal ‘fixing’.2 Persons born with the attributes named with these terms, even if physically healthy, therefore risk unnecessary pathologisation and medicalisation, prompting interventions, often non-voluntary, into their bodies to make them appear or function in ways that are deemed more typically female or male. In addition, some legal and social systems automatically associate persons with these traits with third categories of sex—neither female nor male—which may or may not align with their sex designation at birth, sex of rearing, personal experience or self-conception (see Coda). Being seen as intersex or being judged to have …. (shrink)

When used clinically, psychedelics may appear unusual or even unique when compared to more familiar or long-standing medical interventions, prompting some to suggest that the ethical issues raised may likewise be exceptional. If that is correct, then perhaps psychedelics should be treated differently from other medical substances: for example, by being subjected to different ethical or evidentiary standards. Alternatively, it may be that psychedelics have more in common with various existing medical interventions than first meets the eye. We argue in (...) favor of the latter position, drawing on parallels from earlier debates around genetic exceptionalism in bioethics. We suggest there are risks to adopting a stance of “psychedelic ethical exceptionalism,” and propose that consistent ethical rules and evidentiary standards should be applied across all relevant areas of clinical medicine. Importantly, this does not preclude the possibility that changes to existing standards should be made; but if so, this should not be justified by appealing to the alleged uniqueness of psychedelics.

ABSTRACT:Psychedelics, including psilocybin, and other consciousness-altering compounds such as 3,4-methylenedioxymethamphetamine (MDMA), currently are being scientifically investigated for their potential therapeutic uses, with a primary focus on measurable outcomes: for example, alleviation of symptoms or increases in self-reported well-being. Accordingly, much recent discussion about the possible value of these substances has turned on estimates of the magnitude and duration of persisting positive effects in comparison to harms. However, many have described the value of a psychedelic experience with little or no reference (...) to such therapeutic benefits, instead seeming to find the experience valuable in its own right. How can we make sense of such testimony? Could a psychedelic experience be valuable even if there were no persisting beneficial effects? If so, how? Using the concept of psychological richness, combined with insights from the philosophy of aesthetics and the enhancement literature, this essay explores potential sources of value in the acute subjective experience, apart from the value derived from persisting beneficial effects.

Psychedelics such as psilocybin reliably produce significantly altered states of consciousness with a variety of subjectively experienced effects. These include certain changes to perception, cognition, and affect,1 which we refer to here as the acute subjective effects of psychedelics. In recent years, psychedelics such as psilocybin have also shown considerable promise as therapeutic agents when combined with talk therapy, for example, in the treatment of major depression or substance use disorder.2 However, it is currently unclear whether the aforementioned acute subjective (...) effects are necessary to bring about the observed therapeutic effects of psilocybin and other psychedelics. This uncertainty has sparked a lively—though still largely hypothetical—debate on whether psychedelics without subjective effects (“nonsubjective psychedelics” or “non-hallucinogenic psychedelics”) could still have the same therapeutic impact, or whether the acute subjective effects are in fact necessary for this impact to be fully realized.3,4,5.

We propose to expand the conversation around moral enhancement from direct brain-altering methods to include technological means of modifying the environments and media through which agents can achieve moral improvement. Virtual Reality (VR) based enhancement would not bypass a person’s agency, much less their capacity for reasoned reflection. It would allow agents to critically engage with moral insights occasioned by a technologically mediated intervention. Users would gain access to a vivid ‘experience machine’ that allows for embodied presence and immersion in (...) a virtual world that meaningfully replicates relevant aspects of real life. We explore how VR can train empathy and foster moral growth in complex ways that would be inaccessible even for traditional moral education. Virtual Reality Perspective Taking is a unique medium for making empathy more reflective. (shrink)

The question of what makes someone the same person through time and change has long been a preoccupation of philosophers. In recent years, the question of what makes ordinary or lay people judge that someone is—or isn’t—the same person has caught the interest of experimental psychologists. These latter, empirically oriented researchers have sought to understand the cognitive processes and eliciting factors that shape ordinary people’s judgments about personal identity and the self. Still more recently, practitioners within an emerging discipline, experimental (...) philosophical bioethics or “bioxphi”—the focus of this chapter—have adopted a similar aim and employed similar methodologies, but with two distinctive features: (a) a special concern for enhanced ecological validity in the examples and populations studied; and (b) an interest in contributing to substantive normative debates within the wider field of bioethics. Our aim in this chapter is to sample illustrative work on personal identity in bioxphi, explore how it relates to studies in psychology covering similar terrain, and draw out the implications of this work for matters of bioethical concern. In pursuing these issues, we highlight recent work in bioxphi that includes the perceived validity of advance directives following neurodegeneration, the right of psychologically altered study participants to withdraw from research, how drug addiction may cause one to be regarded by others as “a completely different person,” the effect of deep-brain stimulation on perceptions of the self, and the potential influence of moral enhancement interventions on intuitive impressions of a person’s character.

Past research has found that the value of a person's activities can affect observers' judgments about whether that person is experiencing certain emotions (e.g., people consider morally good agents happier than morally bad agents). One proposed explanation for this effect is that emotion attributions are influenced by judgments about fittingness (whether the emotion is merited). Another hypothesis is that emotion attributions are influenced by judgments about the agent's true self (whether the emotion reflects how the agent feels “deep down”). We (...) tested these hypotheses in six studies. After finding that people think a wide range of emotions can be fitting and reflect a person's true self (Study 1), we tested the predictions of these two hypotheses for attributions of happiness, love, sadness, and hatred. We manipulated the emotions' fittingness (Studies 2a-b and 4) and whether the emotions reflected an agent's true self (Studies 3 and 5), measuring emotion attributions as well as fittingness judgments and true self judgments. The fittingness manipulation only impacted emotion attributions in the cases where it also impacted true self judgments, whereas the true self manipulation impacted emotion attribution in all cases, including those where it did not impact fittingness judgments. These results cast serious doubt on the fittingness hypothesis and offer some support for the true self hypothesis, which could be developed further in future work. -/- . (shrink)

In addition to facing the known competitors in the formal economy, entrepreneurs must also be concerned with rivalry emanating from the informal economy. The informal economy is characterized by actions outside the normal scope of commerce, such as unsanctioned payments and gift-giving, as means of influencing competition. Scholars and policy makers alike have an interest in mitigating the impacts of such informal activity in that it might present an obstacle for legitimate commerce. Received theory suggests that country institutions can enable (...) and constrain productive activity, and, in doing so, influence competitive obstacles in a country. Leveraging 13,670 responses from entrepreneurs distributed across 59 countries, we provide evidence that two particular types of enabling institutions, countries’ property rights regulations and cooperative actions, are useful for lowering the obstacles presented by informal activity. We also find evidence that two constraining institutions, economic and financial regulations lead to more obstacles presented by informal activity. We describe implications for entrepreneurs, policy makers, and future researchers stemming from these findings. (shrink)

This first article is intended as a brief introduction to the general philosophical assumptions of Newton: namely, his mathematicism, empiricism, positivism, reductionism, and dualism. These five "isms" provide an important background to the main articles that are also briefly described.

Rome and Carthage had established peaceful diplomatic relations before 300 b.c. — as early as the close of the sixth century according to Polybius, whose dating there no longer seems good cause to doubt. A second treaty was struck probably in 348. Both dealt essentially with traders' and travellers' obligations and entitlements, so any military or political terms sprang from that context. In both, the Carthaginians agreed to hand over any independent town they captured in Latium. In the first treaty (...) they were not to establish a fort in Latium either; in the second, the Romans were not to found a city in Carthaginian Africa, Spain or Sardinia. But independent military considerations are the stuff of a third treaty concluded during Rome's war with Pyrrhus. Rome and Carthage now pledged each other military aid in certain circumstances, as we shall see. And ‘geopolitical’ concerns of a very broad kind imbued a treaty which was reported by the third-century historian Philinus of Agrigentum. By this, he stated, ‘the Romans must keep out of the whole of Sicily, the Carthaginians out of Italy’ . This is Polybius' citation of Philinus' allegation; Polybius himself then roundly rejects the very existence of such a pact and declares himself at a loss to understand how his predecessor could record it, but modern scholarship is no longer all that ready to accept his view. A strong majority of historians prefer to follow the Agrigentine, and many see 306 b.c. as the likely year for the agreement because Livy records a ‘renewal’ then of a foedus with Carthage. (shrink)

Participation in research is supposed to be voluntary and informed. Yet it is difficult to ensure people are adequately informed about the potential uses of their biological materials when they donate samples for future research. We propose a novel consent framework which we call “demonstrated consent” that leverages blockchain technology and generative AI to address this problem. In a demonstrated consent model, each donated sample is associated with a unique non-fungible token (NFT) on a blockchain, which records in its metadata (...) information about the planned and past uses of the sample in research, and is updated with each use of the sample. This information is accessible to a large language model (LLM) customized to present this information in an understandable and interactive manner. Thus, our model uses blockchain and generative AI technologies to track, make available, and explain information regarding planned and past uses of donated samples. (shrink)

Aristotle's rejection of the Platonic ideas robbed him of Plato's unity of Being and Value as well. By an extensive, clear interpretation and analysis of the whole Aristotelian corpus, Oates shows that Aristotle lacks a coherent theory of value. While considerations of value unavoidably occur in the Metaphysics, just as ontological ones do in the Ethics, nowhere in Aristotle is there a unification of axiology and ontology. For this reason, Oates argues, the Nicomachean Ethics fails to be a theory of (...) moral good. The book is a temperate, perhaps non-controversial critique of Aristotle, and its polished, easy style makes it a pleasure to read.—A. B. D. (shrink)

A far less exhaustive work than Richardson's scholarly tome, but more focused than Vycinas' ventriloquial interpretation, Guilead's book concentrates on the theme of freedom in Sein und Zeit and in Heidegger's later works. The author is in full control of Heidegger's terminology and he succinctly reports how Heidegger uncovers and destroys the subjectivism of modern philosophy, as represented by Descartes, Leibniz, Kant, Nietzsche, and Marx. Guilead contends that the germ of the "Kehre" was already present in Sein und Seit [[sic]]. (...) Heidegger's later thought shows that man is a cosmic being, a relation to Being, and his freedom can not be rooted in subjectivity but in the realization of his authentic cosmic being, in his "habitation," "dwelling," and "building." The author finds two problems in Heidegger's philosophy: a lack of real otherness in beings, and a danger of humanizing Being. But are they not one problem?—A. B. D. (shrink)

This is a compact, comparative analysis of Western and Chinese thought according to distinctive styles of thought and attitudes toward the world and what can be known of it. The model of Western Philosophy is presented as an abstract whole beyond experience—the Kantian ideal; the model of Chinese thought is a concrete whole found in experience. Chinese thought, as amply represented by passages from Confucius, Mencius and others, always has a feeling for the concrete, for a particular fact intuitively suggesting (...) a universal law; and it always has a predilection for paradox. The author thinks that abstract Western thought is still under the sway of Kant's concepts and forms of judgment, even in its current tendency toward the concrete.—A. B. D. (shrink)
