Philosophers have rightly condemned lookism—that is, discrimination in favor of attractive people or against unattractive people—in education, the justice system, the workplace and elsewhere. Surprisingly, however, the almost universal preference for attractive romantic and sexual partners has rarely received serious ethical scrutiny. On its face, it’s unclear whether this is a form of discrimination we should reject or tolerate. I consider arguments for both views. On the one hand, a strong case can be made that preferring attractive partners is bad. (...) The idea is that choosing partners based on looks seems essentially similar to other objectionable forms of discrimination. (In particular, the preference for attractive partners is arguably both unfair and harmful to a significant degree.) One can try to resist this conclusion in several ways. I consider three possible replies. The first has to do with the possibility of controlling our partner preferences. The second pertains to attractiveness and “good genes”. The last attempts to link certain aspects of attractiveness to a prospective partner’s personality and values. I argue that the first two replies fail conclusively, while the third only amounts to a limited defense of a particular kind of attractiveness preference. So the idea that we should often avoid preferring attractive partners is compelling. (shrink)

We discuss potential biorisks from large language models (LLMs). AI assistants based on LLMs such as ChatGPT have been shown to significantly reduce barriers to entry for actors wishing to synthesize dangerous, potentially novel pathogens and chemical weapons. The harms from deploying such bioagents could be further magnified by AI-assisted misinformation. We endorse several policy responses to these dangers, including prerelease evaluations of biomedical AIs by subject-matter experts, enhanced surveillance and lab screening procedures, restrictions on AI training data, and access (...) controls on biomedical AI. We conclude with a suggestion about future research directions in bioethics. (shrink)

According to a widespread view in metaphysics and philosophy of science, all explanations involve relations of ontic dependence between the items appearing in the explanandum and the items appearing in the explanans. I argue that a family of mathematical cases, which I call “viewing-as explanations”, are incompatible with the Dependence Thesis. These cases, I claim, feature genuine explanations that aren’t supported by ontic dependence relations. Hence the thesis isn’t true in general. The first part of the paper defends this claim (...) and discusses its significance. The second part of the paper considers whether viewing-as explanations occur in the empirical sciences, focusing on the case of so-called fictional models. It’s sometimes suggested that fictional models can be explanatory even though they fail to represent actual worldly dependence relations. Whether or not such models explain, I suggest, depends on whether we think scientific explanations necessarily give information relevant to intervention and control. Finally, I argue that counterfactual approaches to explanation also have trouble accommodating viewing-as cases. (shrink)

The problem of truth in fiction concerns how to tell whether a given proposition is true in a given fiction. Thus far, the nearly universal consensus has been that some propositions are ‘implicitly true’ in some fictions: such propositions are not expressed by any explicit statements in the relevant work, but are nevertheless held to be true in those works on the basis of some other set of criteria. I call this family of views ‘implicitism’. I argue that implicitism faces (...) serious problems, whereas the opposite view is much more plausible than has previously been thought. After mounting a limited defence of explicitism, I explore a difficult problem for the view and discuss some possible responses. (shrink)

Philosophers of science since Nagel have been interested in the links between intertheoretic reduction and explanation, understanding and other forms of epistemic progress. Although intertheoretic reduction is widely agreed to occur in pure mathematics as well as empirical science, the relationship between reduction and explanation in the mathematical setting has rarely been investigated in a similarly serious way. This paper examines an important particular case: the reduction of arithmetic to set theory. I claim that the reduction is unexplanatory. In defense (...) of this claim, I offer evidence from mathematical practice, and I respond to contrary suggestions due to Steinhart, Maddy, Kitcher and Quine. I then show how, even if set-theoretic reductions are generally not explanatory, set theory can nevertheless serve as a legitimate foundation for mathematics. Finally, some implications of my thesis for philosophy of mathematics and philosophy of science are discussed. In particular, I suggest that some reductions in mathematics are probably explanatory, and I propose that differing standards of theory acceptance might account for the apparent lack of unexplanatory reductions in the empirical sciences.

Much recent work on mathematical explanation has presupposed that the phenomenon involves explanatory proofs in an essential way. I argue that this view, ‘proof chauvinism’, is false. I then look in some detail at the explanation of the solvability of polynomial equations provided by Galois theory, which has often been thought to revolve around an explanatory proof. The article concludes with some general worries about the effects of chauvinism on the theory of mathematical explanation. 1Introduction 2Why I Am Not a (...)

The field of AI safety aims to prevent increasingly capable artificially intelligent systems from causing humans harm. Research on moral alignment is widely thought to offer a promising safety strategy: if we can equip AI systems with appropriate ethical rules, according to this line of thought, they'll be unlikely to disempower, destroy or otherwise seriously harm us. Deontological morality looks like a particularly attractive candidate for an alignment target, given its popularity, relative technical tractability and commitment to harm-avoidance principles. I (...) argue that the connection between moral alignment and safe behavior is more tenuous than many have hoped. In general, AI systems can possess either of these properties in the absence of the other, and we should favor safety when the two conflict. In particular, advanced AI systems governed by standard versions of deontology need not be especially safe. (shrink)

Mathematicians distinguish between proofs that explain their results and those that merely prove. This paper explores the nature of explanatory proofs, their role in mathematical practice, and some of the reasons why philosophers should care about them. Among the questions addressed are the following: what kinds of proofs are generally explanatory (or not)? What makes a proof explanatory? Do all mathematical explanations involve proof in an essential way? Are there really such things as explanatory proofs, and if so, how do (...) they relate to the sorts of explanation encountered in philosophy of science and metaphysics? (shrink)

Gauss’s quadratic reciprocity theorem is among the most important results in the history of number theory. It’s also among the most mysterious: since its discovery in the late 18th century, mathematicians have regarded reciprocity as a deeply surprising fact in need of explanation. Intriguingly, though, there’s little agreement on how the theorem is best explained. Two quite different kinds of proof are most often praised as explanatory: an elementary argument that gives the theorem an intuitive geometric interpretation, due to Gauss (...) and Eisenstein, and a sophisticated proof using algebraic number theory, due to Hilbert. Philosophers have yet to look carefully at such explanatory disagreements in mathematics. I do so here. According to the view I defend, there are two important explanatory virtues—depth and transparency—which different proofs (and other potential explanations) possess to different degrees. Although not mutually exclusive in principle, the packages of features associated with the two stand in some tension with one another, so that very deep explanations are rarely transparent, and vice versa. After developing the theory of depth and transparency and applying it to the case of quadratic reciprocity, I draw some morals about the nature of mathematical explanation. (shrink)

A proof P of a theorem T is transferable when a typical expert can become convinced of T solely on the basis of their prior knowledge and the information contained in P. Easwaran has argued that transferability is a constraint on acceptable proof. Meanwhile, a proof P is fixable when it’s possible for other experts to correct any mistakes P contains without having to develop significant new mathematics. Habgood-Coote and Tanswell have observed that some acceptable proofs are both fixable and (...) in need of fixing, in the sense that they contain nontrivial mistakes. The claim that acceptable proofs must be transferable seems quite plausible. The claim that some acceptable proofs need fixing seems plausible too. Unfortunately, these attractive suggestions stand in tension with one another. I argue that the transferability requirement is the problem. Acceptable proofs need only satisfy a weaker requirement I call “corrigibility”. I explain why, despite appearances, the corrigibility standard is preferable to stricter alternatives. (shrink)

Models are indispensable tools of scientific inquiry, and one of their main uses is to improve our understanding of the phenomena they represent. How do models accomplish this? And what does this tell us about the nature of understanding? While much recent work has aimed at answering these questions, philosophers' focus has been squarely on models in empirical science. I aim to show that pure mathematics also deserves a seat at the table. I begin by presenting two cases: Cramér’s random (...) model of the prime numbers and the function field model of the integers. These cases show that mathematicians, like empirical scientists, rely on unrealistic models to gain understanding of complex phenomena. They also have important implications for some much-discussed theses about scientific understanding. First, modeling practices in mathematics confirm that one can gain understanding without obtaining an explanation. Second, these cases undermine the popular thesis that unrealistic models confer understanding by imparting counterfactual knowledge. (shrink)

When you and I share an experience, each of us lives through a we-experience. The paper claims that we-experiences have unique phenomenality and structure. First, we-experiences’ phenomenality is characterised by the fact that they feel like ours to their subject. This specific phenomenality is contended to derive from the way these experiences self-represent: a we-experience exemplifies us-ness or togetherness because it self-represents as mine qua ours. Second, living through a we-experience together with somebody else is not to have this experience (...) in parallel with the experience of the other. Rather, the paper argues that a we-experience is partly co-constituted by the experience of the other. After offering an account of the phenomenality and constitution of we-experiences, which traces these two elements back to the subject’s self-understanding as a group member, the paper argues for the claim that an experience’s for-us-ness is committal to this experience being co-constituted by another we-experience.

The dominant conception of delusion in psychiatry (in textbooks, research papers, diagnostic manuals, etc.) is predominantly epistemic. Delusions are almost always characterized in terms of their epistemic defects, i.e., defects with respect to evidence, reasoning, judgment, etc. However, there is an individualistic bias in the epistemic conception; the alleged epistemic defects and abnormalities in delusions relate to individualistic epistemic processes rather than social epistemic processes. We endorse the social epistemological turn in recent philosophical epistemology, and claim that a corresponding turn (...) is needed in the study of delusions. It is a turn from the (purely) individualistic conception, which characterizes delusions only by individualistic epistemic defects and abnormalities, to the (partially) social epistemic conception, which characterizes delusions by individualistic as well as social epistemic defects and abnormalities. This paper is intended as an initial step toward such a social epistemological turn. In particular, we will develop a new model of the development of delusions according to which testimonial abnormalities, including testimonial isolation and testimonial discount, are a causal factor in the development of delusions.

The paper offers a systematic reconstruction of the relations that, in Husserl’s work, bind together our shared social world (“the spiritual world”) with shared intentionality. It is claimed that, by sharing experiences, persons create social reasons and that these reasons impose a normative structure on the social world. Because there are two ways in which persons can share experiences (depending on whether these experiences rest on mutual communication or on group’s identity), social normativity comes in two kinds. It is either (...) directed (it has an addressee) or it is collective or absolute (it applies to all group members). Social normativity should be distinguished from axiological normativity: The first is grounded in shared intentionality, the second in values. (shrink)

Is there a circular relationship between trust and ethics? Is it possible to alter their relationship, changing the perception that social actors have of them? How has trust changed in the transition from modernity to post-modernity and how does it change in times of crisis? Starting from the epistemological assumption that progress in the social sciences is determined by the change in the theoretical horizon produced by “a reformulation of metaphysical assumptions” [1] and combining this path with the relational perspective, (...) according to which “not the facts, but the relationship between the facts is what requires analysis” [2], we will examine definitions, meanings, functions and relationships between trust and ethics. Following the theoretical logical method, we will understand that trust and ethical behaviour are particular forms of gift [3] that co-own each other. As such, they are ambivalent in nature and their circle can also produce dysfunctional outcomes that depend on the ability of social systems to modify collective perceptions through forms of communication, in the awareness that distrust constitutes an ineliminable and, paradoxically, preparatory element for the restoration of the trust circle. The relational circle between gift, trust, collective ethics and personal morality does not end with distrust, but changes in a contingent way, determining perverse effects: correct behaviour could produce, unintentionally, a disaster; incorrect actions could generate unforeseen positive effects.The perverse effects cannot be defined as exceptional - as is believed in the theory of rational choice - but recurrent because daily practices are marked by an intuitive, emotional and moralistic trust circle that prevails over logical reasoning, as ascertained by both relational theory and behavioural economics. Functionalist paradigms cannot engineer and optimise the performance of trust. [1] See J. Alexander's strong programme in S. Segre, Le teorie sociologiche contemporanee, Carocci, Rome, 2019, p. 12.

In order to rebuild a useful theory that can aid in producing a profound change from the bottom up, it is fundamental to return to some of Habermas' greatest texts from his first thirty year of research and teaching, written by the Habermas who neo-reactionary and opportunitst Karl Marx considers dangerous because his ideas are too extreme and left-wing"--Page 4 of cover.

The centuries-long evolution of the iconography of Niccolò Machiavelli is itself a chapter in the history of Machiavelli’s reputation. As intuited by one of his foremost biographers, Oreste Tommasini, portraits of the Florentine are probably best considered as visual expressions of philosophical and literary anti-Machiavellism, which exercised, in their own way, a negative influence on the reception and interpretations of his writings. The Machiavelli who we have seen represented over the course of history in paintings, prints, and engravings may be (...) nothing more, therefore, than a Machiavellian persona: the visual translation of a conventional and stereotypical interpretation, which considers the author of The Prince to be the champion of a politics based on duplicity, cunning, deceit, and guile. This essay examines the origins and dissemination over the centuries of ‘La Testina’, one of the most celebrated and widely publicized portraits of Machiavelli. The conclusion, after comparing all of the extant variants of this portrait, is that it is an unfaithful and invented graphic representation of Machiavelli, whose fortunes in publishing and in the collective imagination have kept pace with the spread of a demonizing interpretation of Machiavelli, the master of evil, well-rooted even today in mass popular culture.

Alfred North Whitehead famously compares the philosophical method of knowledge acquisition with the process of flying an airplane. Likewise, “shamanic flight” marks stages of cognitive processing in navigation through perceptible and imperceptible worlds. This article focuses on the cosmovision of the Amazon people Huni Kuin, the Whiteheadian method of imaginative rationalization, and the concept of Amerindian perspectivism. This study also investigates shamanism as an experience of knowledge generation. Furthermore, “shamanic flight,” as an ecstatic technique experienced in many diverse Amerindian rituals, (...) will be explored as a method in the discovery and organization of nonhuman alterities. Finally, Amazonian-based shamanic epistemology will be discussed within a “multinaturalist” ontology. (shrink)

Whiteheadian concepts of life, food, "empty" and "occupied space" provide a theoretical basis to unpack an ontogenetic perspective on aging. Focusing on the so-called "Selective Optimization with Compensation " strategy, this work will explore this concept in relation to some scientific evidence in the fields of "epigenetics " and molecular nutrition. Further, the role of caloric restriction in health and longevity will be discussed as a SOC strategy, based on the metabolic theory of aging. SOC strategy applied to the processes (...) of aging, when linked with Whitehead's philosophy of organism, makes it possible for us to think about life as a selective process provided by "empty space. " A continuum within the physical field optimizes a "living society," which evolves in permanent social deficit, by means of compensation by nutritional metabolism. (shrink)

The present article conceptualizes morally controversial innovations as a category of innovations that raise ethical issues due to their potentially undesirable long-term consequences on society or the natural environment. Then, it analyzes the case of biofuel crops by applying an extended version of the theory of planned behavior, which includes moral norm and ethical self-identity. The obtained results show that attitude and subjective norms are positively related to farmers' intention to grow biofuel crops. Yet the intention of those farmers with (...) a higher ethical self-identity is also influenced by perceived behavioral control and moral norm. In particular, moral norm negatively affects their intention to grow biofuel crops, thus restraining the adoption of this innovation. Implications for theory, as well as for policymakers interested in promoting the diffusion of morally controversial innovations, are discussed. (shrink)

The present paper proposes to establish the data that can be drawn securely from a controversial testimonium on an oration of Cato contained in a late antique panegyric.13.3), and to illustrate some of its textual and exegetical problems. Further, in the light of a hitherto overlooked comparison with a gloss of Festus, proposals are made: for a new constitutio and interpretation of the text of the panegyric; and for the identification of a textual citation from the orations of Cato the (...) Censor, and the identification with Cato of the anonymous antiqui to whom Festus attributes the use of the rare substantive oliueta in feminine singular with the sense of ‘gathering of olives’. Finally some considerations are offered on the possible sources used by Festus and by the panegyrist. (shrink)

ABSTRACT ‘We’ is said in many ways. This paper investigates Kurt Stavenhagen’s neglected account of different kinds of ‘we’, which is maintained to be one of the most sophisticated within classical phenomenology. The paper starts by elaborating on the phenomenological distinction between mass, society, and community by claiming that individuals partake in episodes of experiential sharing only within communities. Stavenhagen conceptualizes experiential sharing as a meshing of conscious experiences infused by a feeling of us-ness. The remainder of the paper focuses (...) on Stavenhagen’s distinction of various senses of us: when individual share preferences, have mutual respect, or emotionally evaluate the world according to a cultural tradition, they elicit a sense of us of different kind and, thus, form communities of different kind. Within phenomenology, Stavenhagen should be credited with the merit of having unearthed the aggregative, we-generating force of preferences, of respect, and of (certain) emotions. (shrink)
