What does it mean to consider the world of AI through a Christian lens? Rapid developments in AI continue to reshape society, raising new ethical questions and challenging our understanding of the human person. Encountering Artificial Intelligence draws on Pope Francis’ discussion of a culture of encounter and broader themes in Catholic social thought in order to examine how current AI applications affect human relationships in various social spheres and offers concrete recommendations for better implementation. The document also explores questions (...) regarding personhood, consciousness, and the kinds of relationships humans might have with even the most advanced AI. Through these discussions, this book investigates the theoretical and practical challenges to interpersonal encounter raised by the age of AI.

Summary By using the example of a single proposition and its diagrams, this paper makes explicit a number of the processes in effect in the textual transmission of works in the exact sciences of the ancient and medieval periods. By examining the diagrams of proposition 13 as they appear in the Greek, Arabic, and Latin traditions of Aristarchus's On the Sizes and Distances of the Sun and Moon, we can see a number of ways in which medieval, and early (...) modern, scholars interpreted their sources in an effort to understand and transmit canonical ancient texts. This study highlights the need for modern scholars to take into consideration all aspects of the medieval transmission in our efforts to understand ancient practices. (shrink)

Epistemic trespassers judge matters outside their field of expertise. Trespassing is ubiquitous in this age of interdisciplinary research and recognizing this will require us to be more intellectually modest.

The concept of a reason is now central to many areas of contemporary philosophy. Key theses in ethics, epistemology, political philosophy, philosophy of action, and the philosophy of the emotions, among others, have come to be framed in terms of reasons. And yet, despite their centrality, theorists seem to take inconsistent things for granted about how reasons work, what kinds of things can be reasons, what reasons favor, and more. Somehow reasons have come to be both indispensable and impenetrable. -/- (...) The Fundamentals of Reasons offers a comprehensive introduction to the philosophy of reasons. Focusing on the twin roles of reasons in explanation and deliberation, the book not only emphasizes what has made reasons central across philosophy but it also explores why philosophers have such incompatible pictures about what reasons are and how they work. Working from the inside out, Howard and Schroeder identify contentious assumptions about not only the internal structure of reasons but also their relationship to other important concepts, and then show how these contentious assumptions shape the many downstream applications of reasons in ethics, epistemology, political philosophy, and beyond. -/- This mildly opinionated exploration of key questions about the significance and nature of reasons helps the reader to navigate this important part of the philosophical landscape and to get clearer about why reasons seem important and what their import, ultimately, is.

This article evaluates an emerging element in popular debate and inquiry: DYOR. (Haven’t heard of the acronym? Then Do Your Own Research.) The slogan is flexible and versatile. It is used frequently on social media platforms about topics from medical science to financial investing to conspiracy theories. Using conceptual and empirical resources drawn from philosophy and psychology, we examine key questions about the slogan’s operation in human cognition and epistemic culture.

Toward a theory of n-tuples of individuals and concepts as surrogates for Russellian singular propositions and singular concepts. Alonzo Church proposed a powerful and elegant theory of sequences of functions and their arguments as singular-concept surrogates. Church’s account accords with his Alternative (0), the strictest of his three competing criteria for strict synonymy. The currently popular objection to strict criteria like (0) on the basis of the Russell-Myhill paradox is misguided. Russell-Myhill is not a problem specifically for Alternative (0). Rather (...) it is a disproof of unrestricted concept comprehension. Unrestricted comprehension is also inconsistent with facts about sets of properties. It is demonstrated furthermore that the principal rival conception of propositions, as classes of possible worlds, is subject to a fatal philosophical collapse: It follows on that conception, given that each of us is fallible, that everyone believes everything. Although it is far superior to its principal rival conception, Church’s proposed theory is vulnerable under (0) to a version of Russell’s notorious Gray’s /Elegy/ objection. Some amendments to Church’s proposal are proffered that address Russell’s objection, including an amendment first proposed in the present author’s /Frege’s Puzzle/ (1986). Church’s response (personal correspondence) is considered. (shrink)

Rather infamously, Kit Fine provided a series of counter‐examples which purport to show that attempts to understand essence in terms of metaphysical necessity are ‘fundamentally misguided’. Here, my aim is to put forward a new version of modalism that is, I argue, immune to Fine's counter‐examples. The core of this new modalist account is a sparseness restriction, such that an object's essential properties are those sparse properties it has in every world in which it exists. After first motivating this sparseness (...) restriction, I proceed to show how the resulting sparse modalism circumvents Fine's original counter‐examples. After dismissing a potential problem concerning the membership relation, I conclude that, as at least one form of modalism is viable, the project of understanding essence in terms of metaphysical necessity is not so fundamentally misguided after all.

In recent years there has been an explosion of philosophical work on blame. Much of this work has focused on explicating the nature of blame or on examining the norms that govern it, and the primary motivation for theorizing about blame seems to derive from blame’s tight connection to responsibility. However, very little philosophical attention has been given to praise and its attendant practices. In this paper, I identify three possible explanations for this lack of attention. My goal is to (...) show that each of these lines of thought is mistaken and to argue that praise is deserving of careful, independent analysis by philosophers interested in theorizing about responsibility.

Two theses are central to recent work on the epistemology of disagreement: Conciliationism:?In a revealed peer disagreement over P, each thinker should give at least some weight to her peer's attitude. Uniqueness:?For any given proposition and total body of evidence, the evidence fully justifies exactly one level of confidence in the proposition. 1This paper is the product of full and equal collaboration between its authors. Does Conciliationism commit one to Uniqueness? Thomas Kelly 2010 has argued that it does. After some (...) scene-setting (?1), in ?2 we explain and criticize Kelly's argument, thereby defeating his larger argument that Conciliationism deserves no dialectical special treatment. But we argue further that Conciliationists are committed to a disjunction, one of whose disjuncts is Uniqueness, that amounts to an ?extremely strong and unobvious position? (??3?4). If we are correct, theorists should not treat Conciliationism as a default position in debates about the epistemic significance of disagreement. (shrink)

Two theses figure centrally in work on the epistemology of disagreement: Equal Weight (‘EW’) and Uniqueness (‘U’). According to EW, you should give precisely as much weight to the attitude of a disagreeing epistemic peer as you give to your own attitude. U has it that, for any given proposition and total body of evidence, some doxastic attitude is the one the evidence makes rational (justifies) toward that proposition. Although EW has received considerable discussion, the case for U has not (...) been critically evaluated. Endorsing U, we argue, commits one to the highly controversial thesis that whatever fixes your rational attitudes can do so only by fixing what evidence you have. This commitment imposes a relatively demanding requirement on justified belief in U, one that we argue is not satisfied by what is currently the strongest available case for U, due to Roger White [2005]. Our challenge to U makes more trouble for its proponents than do the worries about U expressed by Gideon Rosen [2001] and Thomas Kelly [2010]. Moreover, if Kelly [2010] is correct in thinking that EW “carries with it a commitment to” U—a claim which we accept for reasons similar to Kelly’s but is beyond this paper’s scope (but see Ballantyne and Coffman [forthcoming])—then our challenge to U bears importantly on EW: to the extent that our challenge to U succeeds, EW also suffers.

It is a truth universally acknowledged that a claim of metaphysical modality, in possession of good alethic standing, must be in want of an essentialist foundation. Or at least so say the advocates of thereductive-essence-firstview, according to which all modality is to be reductively defined in terms of essence. Here, I contest this bit of current wisdom. In particular, I offer two puzzles—one concerning the essences of non-compossible, complementary entities, and a second involving entities whose essences are modally ‘loaded’—that together (...) strongly call into question the possibility of reducing modality to essence.

While it is tempting to suppose that an act has moral worth just when and because it is motivated by sufficient moral reasons, philosophers have, largely, come to doubt this analysis. Doubt is rooted in two claims. The first is that some facts can motivate a given act in multiple ways, not all of which are consistent with moral worth. The second is the orthodox view that normative reasons are facts. I defend the tempting analysis by proposing and defending a (...) heterodox account of both normative and motivating reasons that is inspired by Donald Davidson’s primary reasons. We should adopt the heterodox view, I argue, because it addresses an overlooked but fatal defect in the orthodox conception of reasons, of which challenges to the tempting analysis are a special case.

ABSTRACT: Most of what we believe comes to us from the word of others, but we do not always believe what we are told. We often reject thinkers' reports by attributing biases to them. We may call this debunking. In this essay, I consider how debunking might work and then examine whether, and how often, it can help to preserve rational belief in the face of disagreement.

There is general consensus that explainable artificial intelligence is valuable, but there is significant divergence when we try to articulate why, exactly, it is desirable. This question must be distinguished from two other kinds of questions asked in the XAI literature that are sometimes asked and addressed simultaneously. The first and most obvious is the ‘how’ question—some version of: ‘how do we develop technical strategies to achieve XAI?’ Another question is specifying what kind of explanation is worth having in the (...) first place. As difficult and important as the challenges are in answering these questions, they are distinct from a third question: why do we want XAI at all? There is vast literature on this question as well, but I wish to explore a different kind of answer. The most obvious way to answer this question is by describing a desirable outcome that would likely be achieved with the right kind of explanation, which would make the explanation valuable instrumentally. That is, XAI is desirable to attain some other value, such as fairness, trust, accountability, or governance. This family of arguments is obviously important, but I argue that explanations are also intrinsically valuable, because unexplainable systems can be dehumanizing. I argue that there are at least three independently valid versions of this kind of argument: an argument from participation, from knowledge, and from actualization. Each of these arguments that XAI is intrinsically valuable is independently compelling, in addition to the more obvious instrumental benefits of XAI. (shrink)

While intimately familiar, gender eludes theorizing. We argue that well-known challenges to gender’s analysis originate in a subtle ambiguity: questions about gender sometimes express questions about gender categories themselves (e.g., womanhood, manhood, and so on), while at other times expressing questions about what makes someone a member of these categories. Distinguishing these questions accentuates gender’s connections to morality, making a novel “antirealist” view of gender, or as we call it, “unrealist” view, especially natural. Gender’s relations to identity, sex, and social (...) position are illuminated along the way. Taking cues from both historical and contemporary debates in metaethics about the roles that attitudes can play in metaphysical and semantic analysis, we introduce and begin developing a comprehensive non-ameliorative framework for explicating gender’s nature and our thought and talk about it. In a slogan, on the view we defend, you belong to the gender category to which you intrinsically desire to belong. (shrink)

I argue that reflection on philosophers who could have been working among us but aren’t can lead us to give up our philosophical beliefs.

Some philosophers think that the challenge of justifying punishment can be met by a theory that emphasizes the expressive character of punishment. A particular type of theories of this sort - call it Expressive Retributivism [ER] - combines retributivist and expressivist considerations. These theories are retributivist since they justify punishment as an intrinsically appropriate response to wrongdoing, as something wrongdoers deserve, but the expressivist element in these theories seeks to correct for the traditional obscurity of retributivism. Retributivists often rely on (...) appeals to controversial intuitions involving obscure concepts. While retributive intuitions can be compelling, some worry that the justificatory challenge cannot be met merely by appealing to them. ER tries to enhance the clarity and justificatory power of these intuitions and the concepts they invoke by appealing to an expressive conception of punishment. I argue that these theories fail to justify punishment and that there is reason to think that they cannot, in principle, justify punishment. (shrink)

Current discussions of hermeneutical injustice, I argue, poorly characterise the cognitive state of victims by failing to account for the communicative success that victims have when they describe their experience to other similarly situated persons. I argue that victims, especially when they suffer moral wrongs that are yet unnamed, are able (1) to grasp certain salient aspects of the wrong they experience and (2) to cultivate the ability to identify instances of the wrong in virtue of moral emotions. By moral (...) emotions I mean emotions like indignation that reflect an agent’s ethical commitments and bear on her ethical assessments. Further, I argue that victims can impart their partial understanding of the wrong they suffer to others who are not similarly situated by eliciting moral emotions such as pity that are tied to broad notions of justice and fairness.

Some epistemologists hold that exploration and elaboration of the nature of luck will allow us to better understand knowledge. I argue this is a mistake.

During his celebrated 1922 debate with Bergson, Einstein famously proclaimed: “the time of the philosopher does not exist, there remains only a psychological time that differs from the physicist’s.” Einstein’s dictum, I maintain, has been metabolized by the natural sciences, which typically presuppose, more or less explicitly, the existence of a single, univocal, temporal substratum, ultimately determined by physics. This reductionistic assumption pervades much biological and biomedical practice. The chronological age allotted to individuals is conceived as an objective quantity, allowing (...) one to straightforwardly assign and compare the biological age of organisms. This essay argues that the standard practice of assessing the age and aging of organisms against the backdrop of a physical conception of time is problematic. This becomes especially evident in light of recent discoveries of various levels of senescence underlying the development of individual organisms—a phenomenon known as ‘age mosaicism.’ The bottom line is that the study of age and aging requires a biological conception of time, as opposed to a physical one. Einstein clearly wasn’t wrong about his operationalization of time in relativity theory. Still time may be less monolithic than he surmised. (shrink)

ABSTRACTMany philosophers have suggested that disagreement is good grounds for scepticism. One response says that disagreement-motivated scepticism can be mitigated to some extent by the thesis that philosophical disputes are often verbal, not genuine. I consider the implications of this anti-sceptical strategy, arguing that it trades one kind of scepticism for others. I conclude with suggestions for further investigation of the epistemic significance of the nature of philosophical disagreement.

Many philosophers think that punishment is intentionally harmful and that this makes it especially hard to morally justify. Explanations for the latter intuition often say questionable things about the moral significance of the intent to harm. I argue that there’s a better way to explain this intuition.

Much recent work in virtue epistemology has focused on the analysis of such intellectual virtues as responsibility, conscientiousness, honesty, courage, open-mindedness, firmness, humility, charity, and wisdom. Absent from the literature is an extended examination of perseverance as an intellectual virtue. The present paper aims to fill this void. In Sect. 1, I clarify the concept of an intellectual virtue, and distinguish intellectual virtues from other personal characters and properties. In Sect. 2, I provide a conceptual analysis of intellectually virtuous perseverance (...) that places perseverance in opposition to its vice -counterparts, intransigence and irresolution. The virtue is a matter of continuing in one’s intellectual activities for an appropriate amount of time, in the pursuit of intellectual goods, despite obstacles to one’s attainment of those goods. In Sect. 3, I explore relations between intellectually virtuous perseverance and other intellectual virtues. I argue that such perseverance is necessary for the possession and exercise of several other intellectual virtues, including courage. These connections highlight the importance of perseverance in a comprehensive account of such virtues. (shrink)

The aim of this chapter is to explain why Locke thinks religious belief requires evidence and, on his view, what evidence there is for religious belief. I will explain and defend Locke’s view that revelation can provide evidence for religious beliefs so long as there is evidence that God revealed it. Further, I will show how he takes the historical evidence of the miracles of Jesus as justification for belief in Christianity.

How is it that we can rationally assert that sport outcomes do not really matter, while also seeming to care about them to an absurd degree? This is the so-called puzzle of sport. The broadly Waltonian solution to the puzzle has it that we make-believe the outcomes matter. Recently, Stear has critiqued this Waltonian solution, raising a series of five objections. He has also leveraged these objections to motive his own contextualist solution to the puzzle. The aim of this paper (...) is to defend the Waltonian solution. The general upshot is that, contra Stear, a make-believe based solution to the puzzle is viable after all. (shrink)

What can just about any philosophical person who agrees with many goals that are often considered feminist do in response to the problems of the world? Among many other things, they can do philosophy, online, on various social media platforms, to try to help steer the world in better directions, at least a little. -/- Now “doing philosophy” with these goals in mind can mean many different things to different people: there are many different ways to be engaged in “public (...) philosophy.” Here though I’ll briefly describe some what I have been doing for at least a few years, which could be described as a type of “philosophical fact-checking” that basically amounts to this: -/- when people and organizations make importantly problematic claims about philosophical and ethical issues that one has expertise in, provide responses and resources that correct that misinformation.

While there is a great deal to agree with in the essay Expanded Terminal Sedation in End-of-Life Care there is, we think, a need to more fully appreciate the humanistic side of both palliative and end-of-life care.1 Not only does the underlying philosophy of palliative care arguably differ from that which guides curative medicine,2 dying patients are in a uniquely vulnerable position given our cultural disinclination towards open discussions of death and dying. In this brief response, we critically engage Gilbertson (...) et al ’s essay and seek to contextualise the perspective they put forward. According to Cassell, we should distinguish between pain and suffering.3 The former often gives rise to the latter, but suffering has other causes. This includes existential distress, indicating that, unlike pain, suffering is not simply physiological phenomena. Suffering involves the disintegration of the person, meaning that it can impact patient autonomy. Certainly, that a patient is suffering does not equate to a lack autonomy. Nevertheless, we should take care when making decisions in circumstance where the integrity of our embodied personhood is under threat, something that is clearly the case for those who are dying, particularly those who have refractory symptoms while doing so. Generally speaking, refractory symptoms are those which are intractable. They persist despite attempts at palliation. While this implies that such symptoms—and the suffering they cause—cannot be reversed this is not necessarily the case. Not only can the symptoms experienced by dying patients change …. (shrink)

I criticize an increasingly popular set of arguments for the justifiability of punishment. Some philosophers try to justify punishment by appealing to what Peter Strawson calls the reactive attitudes – emotions like resentment, indignation, remorse and guilt. These arguments fail. The view that these emotions commit us to punishment rests on unsophisticated views of punishment and of these emotions and their associated behaviors. I offer more sophisticated accounts of punishment, of these emotions and of their associated behaviors that are consistent (...) with Abolitionism, the view that punishment is unjustified. (shrink)

A major point of debate about morally good motives concerns an ambiguity in the truism that good and strong-willed people desire to do what is right. This debate is shaped by the assumption that “what’s right” combines in only two ways with “desire,” leading to distinct de dicto and de re readings of the truism. However, a third reading of such expressions is possible, first identified by Janet Fodor, which has gone wholly unappreciated by philosophers in this debate. I identify (...) Fodor’s nonspecific reading of “desire to do what’s right” and briefly discuss its merits. (shrink)

To counter the imbalance in vaccine distribution during the COVID-19 pandemic, Albertsen and more recently Germaniet alhave suggested a new system of taxation coined as ‘VaxTax’ that would force higher-income countries to fund the access of low-income and middle-income countries (LMICs) to new vaccines in times of pandemic. I will argue that this idea faces numerous challenges of ethical, sociopolitical and economical nature that may hinder any effort to solve the numerous health challenges that LMICs face. I argue that while (...) it is an interesting idea, it is neither sufficient nor will it ever be easily implemented because of socioeconomic or practical reasons. (shrink)

Economists have long treated technological phenomena as events transpiring inside a black box and, on the whole, have adhered rather strictly to a self-imposed ordinance not to inquire too seriously into what transpires inside that box. The purpose of Professor Rosenberg's work is to break open and examine the contents of the black box. In so doing, a number of important economic problems be powerfully illuminated. The author clearly shows how specific features of individual technologies have shaped a number of (...) variables of great concern to economists: the rate of productivity improvement, the nature of learning processes underlying technological change itself, the speed of technology transfer, and the effectiveness of government policies that are intended to influence technologies in particular ways. The separate chapters of this book reflect a primary concern with some of the distinctive aspects of industrial technologies in the twentieth century, such as the increasing reliance upon science, but also the considerable subtlety and complexity of the dialectic between science and technology. Other concerns include the rapid growth in the development of costs associated with new technologies as well as the difficulty of predicting the eventual performance characteristics of newly emerging technologies.

Walter Sinnott-Armstrong has developed and progressively refined an argument against moral intuitionism—the view on which some moral beliefs enjoy non-inferential justification. He has stated his argument in a few different forms, but the basic idea is straightforward. To start with, Sinnott-Armstrong highlights facts relevant to the truth of moral beliefs: such beliefs are sometimes biased, influenced by various irrelevant factors, and often subject to disagreement. Given these facts, Sinnott-Armstrong infers that many moral beliefs are false. What then shall we think (...) of our own moral beliefs? Either we have reason to think some of our moral beliefs are reliably formed or we have no such reason. If the latter, our moral beliefs are unjustified. If we have reason to think some moral beliefs are reliably formed, then those beliefs are not non-inferentially justified, because then we’ll have reason to accept something—namely, that they are reliably formed—that entails or supports those beliefs. But then, either way, our moral beliefs are not non-inferentially justified, and so moral intuitionism is false. This paper takes issue with Sinnott-Armstrong’s interesting and widely discussed argument, which we here call the Empirical Defeat Argument (EDA). According to us, the EDA does not defeat moral intuitionism. In section 1, we will set out the argument, briefly reviewing the rationale Sinnott-Armstrong offers for the premises. Then, in section 2, we identify a critical but dubious epistemological assumption concerning the nature of defeat that undergirds the argument. Finally, in section 3, we will defend our challenge to the EDA by answering two objections. (shrink)

I argue that contemporary liberal theory cannot give a general justification for the institution or practice of punishment, i.e., a justification that would hold across a broad range of reasonably realistic conditions. I examine the general justifications offered by three prominent contemporary liberal theorists and show how their justifications fail in light of the possibility of an alternative to punishment. I argue that, because of their common commitments regarding the nature of justification, these theorists have decisive reasons to reject punishment (...) in favor of a non-punitive alternative. I demonstrate the possibility of this alternative by means of a careful examination of the nature of punishment, isolating one essential characteristic—the aim to impose suffering—and showing how this characteristic need not guide enforcement. There is logical space for a forceful and coercive, yet non-punitive method of enforcement. This fact poses difficulties for many classical and contemporary justifications of punishment, but it poses particularly crippling problems for general liberal justifications. (shrink)

"Nobis argues that Singer's consequentialist approach is inadequate for defending the moral obligation to become a vegetarian or vegan. The consequentialist case rests on the idea that being a vegetarian or vegan maximizes utility -- the fewer animals that are raised and killed for food, the less suffering. Nobis argues that this argument does not work on an individual level -- my becoming a vegetarian makes no difference to the overall utility of reducing animal suffering in a context of a (...) huge industry and market unaffected by my actions. Nobis merges the insights of virtue ethics with consequentialism to argue that individuals can bring about more goodness if they have the virtues of compassion, care, and sensitivity to unnecessary cruelty and suffering. If one ought to be compassionate, sensitive to cruelty, resist injustice, and be morally integrated, then, Nobis argues, one ought to be a vegetarian or vegan.". (shrink)

Plant-based milk alternatives–or mylks–have surged in popularity over the past ten years. We consider the politics and consumer subjectivities fostered by mylks as part of the broader trend towards ‘plant-based’ food. We demonstrate how mylk companies inherit and strategically deploy positive framings of milk as wholesome and convenient, as well as negative framings of dairy as environmentally damaging and cruel, to position plant-based as the ‘better’ alternative. By navigating this affective landscape, brands attempt to make mylk as simultaneously palatable and (...) disruptive to the status quo. We examine the politics of mylks through the concept of palatable disruption, where people are encouraged to care about the environment, health, and animal welfare enough to adopt mylks but to ultimately remain consumers of a commodity food. By encouraging consumers to reach for “plant-based” as a way to cope with environmental catastrophe and a life out of balance, mylks promote a neoliberal ethic: they individualize systemic problems and further entrench market mechanisms as solutions, thereby reinforcing the political economy of industrial agriculture. In conclusion, we reflect on the limits of the current plant-based trend for transitioning to more just and sustainable food production and consumption. (shrink)

The “somewhat vague, intuitive” notion from computability theory of an effective procedure (method) or algorithm can be fairly precisely defined even if it is not sufficiently formal and precise to belong to mathematics proper (in a narrow sense)—and even if (as many have asserted) for that reason the Church–Turing thesis is unprovable. It is proved logically that the class of effective procedures is not decidable, i.e., that no effective procedure is possible for ascertaining whether a given procedure is effective. This (...) undecidability result is proved directly from the notion itself of an effective procedure, without reliance on any (partly) mathematical lemma, conjecture, or thesis invoking recursiveness or Turing-computability. In fact, there is no reliance on anything very mathematical. The proof does not even appeal to a precise definition of ‘effective procedure’. Instead, it relies solely and entirely on a basic grasp of the intuitive notion of an effective procedure. Though the result that effectiveness is undecidable is not surprising, it is also not without significance. It has the consequence, for example, that the solution to a decision problem, if it is to be complete, must be accompanied by a separate argument that the proposed ascertainment procedure invariably terminates with the correct verdict.

Music and language are universal human abilities with many apparent similarities relating to their acoustics, structure, and frequent use in social situations. We might therefore expect them to be understood and processed similarly, and indeed an emerging body of research suggests that this is the case. But the focus has historically been on the individual, looking at the passive listener or the isolated speaker or performer, even though social interaction is the primary site of use for both domains. Nonetheless, an (...) important goal of emerging research is to compare music and language in terms of acoustics and structure, social interaction, and functional origins to develop parallel accounts across the two domains. Indeed, a central aim of both of evolutionary musicology and language evolution research is to understand the adaptive significance or functional origin of human music and language. An influential proposal to emerge in recent years has been referred to as the social bonding hypothesis. Here, within a comparative approach to animal communication systems, I review empirical studies in support of the social bonding hypothesis in humans, non-human primates, songbirds, and various other mammals. In support of this hypothesis, I review six research fields: (i) the functional origins of music; (ii) the functional origins of language; (iii) mechanisms of social synchrony for human social bonding; (iv) language and social bonding in humans; (v) music and social bonding in humans; and (vi) pitch, tone and emotional expression in human speech and music. I conclude that the comparative study of complex vocalizations and behaviors in various extant species can provide important insights into the adaptive function(s) of these traits in these species, as well as offer evidence-based speculations for the existence of “musilanguage” in our primate ancestors, and thus inform our understanding of the biology and evolution of human music and language.

Recent research offers good reason to think that various psychedelic drugs—including psilocybin, ayahuasca, ketamine, MDMA, and LSD—may have significant therapeutic potential in the treatment of various mental health conditions, including post-traumatic stress disorder, depression, existential distress, and addiction. Although the use of psychoactive drugs, such as Diazepam or Ritalin, is well established, psychedelics arguably represent a therapeutic step change. As experiential therapies, their value would seem to lie in the subjective experiences they induce. As it is the only way for (...) trainee psychedelic therapists to fully understand their subjective effects, some have suggested that firsthand experience of psychedelics should form part of training programs. We question this notion. First, we consider whether the epistemic benefits offered by drug-induced psychedelic experience are as unique as is supposed. We then reflect on the value it might have in regard to the training of psychedelic therapists. We conclude that, absent stronger evidence of the contribution drug-induced experiences make to the training of psychedelic therapists, requiring trainees to take psychedelic drugs does not seem ethically legitimate. However, given the potential for epistemic benefit cannot be entirely ruled out, permitting trainees who wish to gain first-hand experience of psychedelics may be permissible. (shrink)
