More Species, Less Spread: A Global Pattern in Biodiversity Distribution

A central question in ecology is how species are distributed across space and time. In a recent study, Shipley and Saupe [2] investigated the relationship between regional species richness (the number of species present in an area) and regional occupancy (how widely each species occurs within that area). Surprisingly, their findings reveal a consistent, negative relationship: regions with higher biodiversity tend to have fewer species that are broadly distributed

The Normative Power of Resolutions

This article argues that resolutions are reason-giving: when an agent resolves to φ, she incurs an additional normative reason to φ. I argue that the reasons we incur from making resolutions are importantly similar to the reasons we incur from making promises. My account explains why it can be rational for an agent to act on a past resolution even if temptation causes preference and even judgment shifts at the time of action, and offers a response to a common objection to the normativity of resolutions known as the bootstrapping problem, on which if resolutions were reason-giving they would problematically allow us to bootstrap any action into rationality simply by resolving to perform it

Nietzsche on the Eternal Recurrence

The idea of the eternal recurrence is that everyone will live the exact same lives again an infinite number of times. Nietzsche appreciates that this would multiply the value of a single life by infinity, justifying intense emotional responses. His unpublished notes provide a cosmological argument for the eternal recurrence that anticipates Poincaré’s recurrence theorem. Nietzsche’s Thus Spoke Zarathustra describes its hero discovering this idea and struggling to accept the recurrence of all bad things. He eventually comes to love the eternal recurrence because it will bring back all the joys of his life, and teaches this idea to others

Why you shouldn’t serve meat at your next catered event

Much has been written about the ethics of eating meat. Far less has been said about the ethics of serving meat. In this paper I argue that we often shouldn’t serve meat, even if it is morally permissible for individuals to purchase and eat meat. Historically, the ethical conversation surrounding meat has been limited to individual diets, meat producers, and government actors. I argue that if we stop the conversation there, then the urgent moral problems associated with industrial animal agriculture will go unsolved. Instead, we must also consider the important but overlooked role that midsized institutions play in addressing major collective problems. I focus mostly on the harms that industrial animal agriculture inflicts on humans, animals, and the environment, but the discussion bears on other global issues like climate change. Institutional choices are an underexplored avenue for driving social change—their power and influence outstrip individual actions, and they can shape behavior in modest ways that promote social goods. Here I highlight the paradigmatic case of catered events and suggest three ways that institutional actors can reduce meat consumption and shape cultural attitudes surrounding meat: large impact decisions, subtly shaping incentives, and consolidating burdens

Health, Disease, and the Medicalization of Low Sexual Desire: A Vignette-Based Experimental Study

Debates about the genuine disease status of controversial diseases rely on intuitions about a range of factors. Adopting tools from experimental philosophy, this paper explores some of the factors that influence judgments about whether low sexual desire should be considered a disease and whether it should be medically treated. Drawing in part on some assumptions underpinning a divide in the literature between viewing low sexual desire as a genuine disease and seeing it as improperly medicalized, we investigate whether health and disease judgments are affected by factors such as an individual’s gender, the cause of the low desire, whether the desire is high or low, and both personal and societal valuations of the condition. Our main findings indicate that (a) the cause of a condition influences whether it is judged a disorder, (b) how the individual values the condition influences whether the condition is seen as a proper target of medical intervention, and (c) perceived dysfunction influences judgments regarding health, disorder classification, medicalization, and medical intervention. Our findings help further illuminate the intricate interplay of factors that influence judgments about health and disease in controversial conditions

What can we know about unanswerable questions?

I present two arguments that aim to establish logical limits on what we can know. More specifically, I argue for two results concerning what we can know about questions that we cannot answer. I also discuss a line of thought, found in the writings of Pierce and of Rescher, in support of the idea that we cannot identify specific scientific questions that will never be answered

The Depth of Margaret Cavendish's Ecology

We examine Margaret Cavendish’s ecological views and argue that, in the Appendix to her final published work, Grounds of Natural Philosophy (1668), Cavendish is defending a normative account of the way that humans ought to interact with their environment. On this basis, we argue that Cavendish is committed to a form of what, for the purposes of this paper, we call ‘deep ecology,’ where that is understood as the view that humans ought to treat the rest of nature as something of intrinsic value. The reading of Cavendish we defend in this paper also commits her to a naturalistic account of ‘moral facts’ about how humans ought to interact with their environment. That is, on our reading of Cavendish, ‘moral facts’ (i.e., facts about how we ought and ought not to behave, and what it is right or wrong for us to do) are grounded in facts about nature—and, in Cavendish’s case, its (ir)regularity. Such facts are hypothetical, rather than categorical: they are facts about how we ought to act if we wish to attain happiness or flourishing. We thus contend that Cavendish anticipates, at least loosely speaking, movements in both deep ecology and in naturalistic meta-ethics that came to prominence well after the time in which she was writing

Unseen Threats: Health Risks from Low-Dose Radiation Near Nuclear Power Plants

Although international regulations aim to limit radiation exposure, emerging evidence suggests that even low-dose radiation from nuclear power plants may pose significant health risks. A comprehensive meta-analysis by Lin et al. [1], encompassing 47 studies across 17 countries and involving over 480,000 workers and 7.5 million residents, highlights the persistent dangers associated with occupational and environmental exposure within current regulatory limits
