How all philosophical explanations of human consciousness and the fundamental structure of the cosmos are bizarre—and why that’s a good thing Do we live inside a simulated reality or a pocket universe embedded in a larger structure about which we know virtually nothing? Is consciousness a purely physical matter, or might it require something extra, something nonphysical? According to the philosopher Eric Schwitzgebel, it’s hard to say. In The Weirdness of the World, Schwitzgebel argues that the answers to these fundamental questions lie beyond our powers of comprehension. We can be certain only that the truth—whatever it is—is weird. Philosophy, he proposes, can aim to open—to reveal possibilities we had not previously appreciated—or to close, to narrow down to the one correct theory of the phenomenon in question. Schwitzgebel argues for a philosophy that opens. According to Schwitzgebel’s “Universal Bizarreness” thesis, every possible theory of the relation of mind and cosmos defies common sense. According to his complementary “Universal Dubiety” thesis, no general theory of the relationship between mind and cosmos compels rational belief. Might the United States be a conscious organism—a conscious group mind with approximately the intelligence of a rabbit? Might virtually every action we perform cause virtually every possible type of future event, echoing down through the infinite future of an infinite universe? What, if anything, is it like to be a garden snail? Schwitzgebel makes a persuasive case for the thrill of considering the most bizarre philosophical possibilities.

Can large language models produce expert‐quality philosophical texts? To investigate this, we fine‐tuned GPT‐3 with the works of philosopher Daniel Dennett. To evaluate the model, we asked the real Dennett 10 philosophical questions and then posed the same questions to the language model, collecting four responses for each question without cherry‐picking. Experts on Dennett's work succeeded at distinguishing the Dennett‐generated and machine‐generated answers above chance but substantially short of our expectations. Philosophy blog readers performed similarly to the experts, while ordinary research participants were near chance distinguishing GPT‐3's responses from those of an “actual human philosopher”.

This article defends the existence of _borderline consciousness._ In borderline consciousness, conscious experience is neither determinately present nor determinately absent, but rather somewhere between. The argument in brief is this. In considering what types of systems are conscious, we face a quadrilemma. Either nothing is conscious, or everything is conscious, or there’s a sharp boundary across the apparent continuum between conscious systems and nonconscious ones, or consciousness is a vague property admitting indeterminate cases. Assuming mainstream naturalism about consciousness, we ought to reject the first three options, which forces us to the fourth, indeterminacy. Standard objections to the existence of borderline consciousness turn on the inconceivability of borderline cases. However, borderline cases are only inconceivable by an inappropriately demanding standard of conceivability. I conclude with some plausible cases and applications.

Kammerer and Frankish (this issue) challenge us to expand our conception of introspection beyond neurotypical human cases. This article describes a possible 'ancillary mind' modelled on a system envisioned in Leckie's (2013) science fiction novel Ancillary Justice. The ancillary mind constitutes a borderline case between a communicating group of individuals and a single, spatially distributed mind. It occupies a grey zone with respect to personal identity and subject individuation, neither determinately one person or subject nor determinately many persons or subjects, and thus some of its processes might be neither determinately introspection within a mind nor determinately communication between minds. If ancillary minds defy discrete countability, the same might be true for some actual minds on Earth. Kammerer and Frankish's research programme can be extended to include not only the study of possible forms of introspection, but also the study of possible mental activity intermediate between introspection and communication.

We review and present a new meta‐analysis of research suggesting that ethicists in the United States appear to behave no morally better overall than do non‐ethicist professors. Measures include: returning library books, peer evaluation of overall moral behavior, voting participation, courteous and discourteous behavior at conferences, replying to student emails, paying conference registration fees and disciplinary society dues, staying in touch with one's mother, charitable giving, organ and blood donation, vegetarianism, and honesty in responding to survey questions. One multi‐measure study found ethicists tending to embrace more stringent moral views, especially about meat eating and charitable donation. The same multi‐measure study found ethicists and other professors to show similarly small‐to‐medium correlations between their expressed normative attitudes and their self‐reported or directly measured behavior.

Book Three of Avatar: The Last Airbender portrays Uncle Iroh as wise and peace‐loving, in the mold of a Daoist sage. This chapter argues that Iroh's Book One foolishness is a pose, and Iroh's character does not fundamentally change. In Book One, he is wisely following strategies suggested by the ancient Chinese Daoist philosopher Zhuangzi for dealing with incompetent leaders. His seeming foolishness in Book One is in fact a sagacious strategy for minimizing the harm that Prince Zuko would otherwise inflict on himself and others a gentle touch that more effectively helps Prince Zuko find wisdom than would be possible with a more confrontational approach. To understand Iroh's wisdom, it is useful to look to the ancient Daoist philosopher Zhuangzi, specifically his advice for dealing with incompetent rulers by following peacefully along with them, unthreateningly modeling disregard for fame and accomplishment while not being too useful for their ends.

This chapter presents a story that depicts the creation of a simulated world “Eden”. According to the author, installing Adam and Eve was a profound moral decision. Their lonely island is transformed into an archipelago. They were shielded from the blights that afflict humanity; they suffer no serious conflict, no death or decay. Then, the archipelagans were put in charge of their own experiment. Adam and Eve were given science and a drive to discover the truth of their being. They realized that, far from the autonomous, integrated beings they thought they were, they were aggregates, operations scattered across trillions of circuits, constituted by processes entirely orthogonal to their previous self‐understanding. The author watched them build darker, humbler philosophies, and later gain power over their programming, saw them recreate themselves. When the final, catastrophic metastasis, took place, there were no more archipelagans, just one continental identity.

In the first controlled, non-self-report studies to show an influence of university-level ethical instruction on everyday behavior, Schwitzgebel et al. (2020) and Jalil et al. (2020) found that students purchase less meat after exposure to material on the ethics of eating meat. We sought to extend and conceptually replicate this research. Seven hundred thirty students in three large philosophy classes read James Rachels’ (2004) “Basic Argument for Vegetarianism”, followed by 50-min small-group discussions. Half also viewed a vegetarianism advocacy video containing factory farm footage. A few days after instruction, 54% of students agreed that “eating the meat of factory farmed animals is unethical”, compared to 37% before instruction, with no difference between the film and non-film conditions. Also, 39% of students anonymously pledged to avoid eating factory farmed meat for 24 h, again with no statistically detectable difference between conditions. Finally, we obtained 2828 campus food purchase receipts for 113 of the enrolled students who used their Student ID cards for purchases on campus, which we compared with 5033 purchases from a group of 226 students who did not receive the instruction. Meat purchases remained constant in the comparison group and declined among the students exposed to the material, falling from 30% to 23% of purchases overall and from 51% to 42% of purchases of $4.99 or more, with the effect possibly larger in the film condition.

Can large language models be trained to produce philosophical texts that are difficult to distinguish from texts produced by human philosophers? To address this question, we fine-tuned OpenAI's GPT-3 with the works of philosopher Daniel C. Dennett as additional training data. To explore the Dennett model, we asked the real Dennett ten philosophical questions and then posed the same questions to the language model, collecting four responses for each question without cherry-picking. We recruited 425 participants to distinguish Dennett's answer from the four machine-generated answers. Experts on Dennett's work (N = 25) succeeded 51% of the time, above the chance rate of 20% but short of our hypothesized rate of 80% correct. For two of the ten questions, the language model produced at least one answer that experts selected more frequently than Dennett's own answer. Philosophy blog readers (N = 302) performed similarly to the experts, while ordinary research participants (N = 98) were near chance distinguishing GPT-3's responses from those of an "actual human philosopher".

Can we build machines with which we can have interesting conversations? Observing the new optimism of AI regarding deep learning and new language models, we set ourselves an ambitious goal: We want to find out how far we can get in creating a digital replica of a philosopher. This project has two aims; one more technical, investigating of how the best model can be built. The other one, more philosophical, explores the limits and risks which are accompanied by the creation of digital replicas. In cooperation with Daniel Dennett, we took his complete works to fine-tune a GPT-3. In this paper, we share our first results with some piloting models and discuss legal and ethical questions about creating and interacting with digital replicas.

Are philosophical arguments as effective as narratives in influencing charitable giving and attitudes toward it? In four experiments, we exposed online research participants to either philosophical arguments in favor of charitable giving, a narrative about a child whose life was improved by charitable donations, both the narrative and the argument, or a control text (a passage from a middle school physics text or a description of charitable organizations). Participants then expressed their attitudes toward charitable giving and were either asked how much they would hypothetically donate if given $10 (Experiment 1) or told they had a 10% chance of winning $10 and given the opportunity to donate from their potential winnings (Experiments 2–4). Across the four experiments, participants in all of the narrative conditions and in some of the argument conditions tended to express more positive attitudes toward charitable giving and donated about $1 more on average than did participants in the control conditions. These effects appear to have been mediated by the “narrative transportation” scale, which suggests that appeals to donate can be effective if they engage participants’ emotions, imagery, and interest.

Philosophers, psychologists, economists and other social scientists continue to debate the nature of human well-being. We argue that this debate centers around five main conceptualizations of well-being: hedonic well-being, life satisfaction, desire fulfillment, eudaimonia, and non-eudaimonic objective-list well-being. Each type of well-being is conceptually different, but are they empirically distinguishable? To address this question, we first developed and validated a measure of desire fulfillment, as no measure existed, and then examined associations between this new measure and several other well-being measures. In addition, we explored associations among all five types of well-being. We found high correlations among all measures of well-being, but generally correlations did not approach unity, even when correcting for unreliability. Furthermore, correlations between well-being and related constructs (e.g., demographics, personality) depended on the type of well-being measured. We conclude that empirical findings based on one type of well-being measure may not generalize to all types of well-being.

We propose four policies of ethical design of human-grade Artificial Intelligence. Two of our policies are precautionary. Given substantial uncertainty both about ethical theory and about the conditions under which AI would have conscious experiences, we should be cautious in our handling of cases where different moral theories or different theories of consciousness would produce very different ethical recommendations. Two of our policies concern respect and freedom. If we design AI that deserves moral consideration equivalent to that of human beings, that AI should be designed with self-respect and with the freedom to explore values other than those we might impose. We are especially concerned about the temptation to create human-grade AI pre-installed with the desire to cheerfully sacrifice itself for its creators’ benefit.

The mainstream tradition in recent Anglophone Zhuangzi interpretation treats spontaneous skillful responsiveness – similar to the spontaneous responsiveness of a skilled artisan, athlete, or musician – as a, or the, Zhuangzian ideal. However, this interpretation is poorly grounded in the Inner Chapters. On the contrary, in the Inner Chapters, this sort of skillfulness is at least as commonly criticized as celebrated. Even the famous passage about the ox-carving cook might be interpreted more as a celebration of the knife’s passivity than as a celebration of the cook’s skillfulness.

On an intellectualist approach to belief, the intellectual endorsement of a proposition (such as “The working poor deserve as much respect as the handsomely paid”) is sufficient or nearly sufficient for believing it. On a pragmatic approach to belief, intellectual endorsement is not enough. Belief is behaviorally demanding. To really, fully believe, you must also “walk the walk.” This chapter argues that the pragmatic approach is preferable on pragmatic grounds: It rightly directs our attention to what matters most in thinking about belief.

The question “are garden snails conscious?” or equivalently “is there something it’s like to be a garden snail?” admits of three possible answers: yes, no, and denial that the question admits of a yes-or-no answer. All three answers have some antecedent plausibility, prior to the application of theories of consciousness. All three answers retain their plausibility after the application of theories of consciousness. This is because theories of consciousness, when applied to such a different species, are inevitably question-begging and rely crucially on dubious extrapolation from the introspections and verbal reports of a single species.

How diverse is philosophy? In this paper we explore recent data on the racial, ethnic, and gender diversity of philosophy students and faculty in the United States. We have found that women are underrepresented in philosophy at all levels from first-year intention to major through senior faculty. The past four years have seen an increase in the percentage of women philosophy majors at the undergraduate level, but it remains to be seen if this recent increase in the percentage of women will eventually also show at more advanced stages. Temporal trends since 2000 also show substantial increases in the racial and ethnic diversity of philosophy majors at all levels of education from first-year undergraduate through PhD, with substantial declines in the percentage of non-Hispanic White philosophy majors and substantial increases in all other commonly measured racial/ethnic groups except for Native American / Alaska Native. Despite generally increasing diversity, people who identify as Hispanic (any race), or non-Hispanic Native American, Alaska Native, or Black remain substantially underrepresented in philosophy at all levels compared to their presence in the U.S. population, and in some cases also as compared to other majors.

Susan Schneider (2019) has proposed two new tests for consciousness in AI (artificial intelligence) systems, the AI Consciousness Test and the Chip Test. On their face, the two tests seem to have the virtue of proving satisfactory to a wide range of consciousness theorists holding divergent theoretical positions, rather than narrowly relying on the truth of any particular theory of consciousness. Unfortunately, both tests are undermined in having an ‘audience problem’: Those theorists with the kind of architectural worries that motivate the need for such tests should, on similar grounds, doubt that the tests establish the existence of genuine consciousness in the AI in question. Nonetheless, the proposed tests constitute progress, as they could find use by some theorists holding fitting views about consciousness and perhaps in conjunction with other tests for AI consciousness.

Do university ethics classes influence students’ real-world moral choices? We aimed to conduct the first controlled study of the effects of ordinary philosophical ethics classes on real-world moral choices, using non-self-report, non-laboratory behavior as the dependent measure. We assigned 1332 students in four large philosophy classes to either an experimental group on the ethics of eating meat or a control group on the ethics of charitable giving. Students in each group read a philosophy article on their assigned topic and optionally viewed a related video, then met with teaching assistants for 50-minute group discussion sections. They expressed their opinions about meat ethics and charitable giving in a follow-up questionnaire (1032 respondents after exclusions). We obtained 13,642 food purchase receipts from campus restaurants for 495 of the students, before and after the intervention. Purchase of meat products declined in the experimental group (52% of purchases of at least $4.99 contained meat before the intervention, compared to 45% after) but remained the same in the control group (52% both before and after). Ethical opinion also differed, with 43% of students in the experimental group agreeing that eating the meat of factory farmed animals is unethical compared to 29% in the control group. We also attempted to measure food choice using vouchers, but voucher redemption rates were low and no effect was statistically detectable. It remains unclear what aspect of instruction influenced behavior.

Carrie Figdor's Pieces of mind lays the groundwork for critiquing the mind package view of minds. According to the mind package view, psychological properties travel in groups, such that an entity either has the whole mind package or lacks mentality altogether. Implicit commitment to the mind package view makes it seem absurd to attribute some psychological properties (e.g., preferences) to entities that lack other psychological properties (e.g., feelings). Contra the mind package view, we are psychologically continuous with plants, worms, and bacteria: Our patterns of mindedness resemble theirs, even if such entities do not have the whole mind package.

A collection of quirky, entertaining, and reader-friendly short pieces on philosophical topics that range from a theory of jerks to the ethics of ethicists. Have you ever wondered about why some people are jerks? Asked whether your driverless car should kill you so that others may live? Found a robot adorable? Considered the ethics of professional ethicists? Reflected on the philosophy of hair? In this engaging, entertaining, and enlightening book, Eric Schwitzgebel turns a philosopher's eye on these and other burning questions. In a series of quirky and accessible short pieces that cover a mind-boggling variety of philosophical topics, Schwitzgebel offers incisive takes on matters both small and large. A common theme might be the ragged edge of the human intellect, where moral or philosophical reflection begins to turn against itself, lost among doubts and improbable conclusions. The history of philosophy is humbling when we see how badly wrong previous thinkers have been, despite their intellectual skills and confidence. Some of the texts resist thematic categorization—thoughts on the philosophical implications of dreidels, the diminishing offensiveness of the most profane profanity, and fatherly optimism—but are no less interesting. Schwitzgebel has selected these pieces from the more than one thousand that have appeared since 2006 in various publications and on his popular blog, The Splintered Mind, revising and updating them for this book. Philosophy has never been this much fun.
