Perin argues that theSceptic is engaged in the search for truth and that since this is so, the Sceptic aims to satisfy certain basic rational requirements.

The Academics offered an argument from twins or perceptually indiscernible objects and an argument from dreams or madness in support of the indiscernibility thesis: that every true perceptual impression is such that some false impression just like it is possible. I claim that these arguments, unlike modern sceptical arguments, are supposed to establish mere counterfactual rather than epistemic possibilities. They purport to show that for any true perceptual impression j, there are a number of alternative causal histories j might have (...) had which would not have resulted in any change in the way in which j represents its object.

This chapter contains section titled: Introduction The Structure of Skeptical Arguments The Arguments of the Ancient Skeptics Reasons for Doubt vs. Reasons for Suspending Judgment Two Puzzles References and Further Reading.

This paper takes up two questions. Is there a sense in which the Sceptic as described by Sextus Empiricus is detached from himself? Does this self-detachment by itself make the Sceptic’s way of life undesirable? I sketch two conceptions of self-detachment, and then conclude that the Sceptic faces a dilemma: either he is more detached from himself than the non-Sceptic or he is vulnerable to a non-standard version of the apraxia objection.

In response to Tad Brennan’s critical notice of The Demands of Reason, I offer further arguments in defense of the distinction between appearance and belief, the claim that truth for its own sake is the Pyrrhonist’s goal, and the centrality of the rationalist interpretation of Sextus’s work.

This chapter concentrates on the edges of the lived body, which act to mediate between the outermost and innermost edges. The prospects for construing bodily edges are explored. Bodily edges realise the paradigm of definitive but incomplete self-knowledge in a very particular way: namely, that such edges are parts of parts. The internal and external edges of bodily parts are not only glimpsed in the course of ongoing experience but also offer a grip for hands. Inside/outside is an especially significant (...) binary edge structure, and is altogether central to edges that inhere in bodies. Bodily edges act as the mediatrix between the edges of the perceived earth and those of the inner psyche, and also provide the conjunctures for many things in experienced life-worlds. (shrink)

Since the development of assisted reproductive technologies, infertile individuals have crossed borders to obtain treatments unavailable or unaffordable in their own country. Recent media coverage has focused on the outsourcing of surrogacy to developing countries, where the cost for surrogacy is significantly less than the equivalent cost in a more developed country. This paper discusses the ethical arguments against international surrogacy. The major opposition viewpoints can be broadly divided into arguments about welfare, commodification and exploitation. It is argued that the (...) only valid objection to international surrogacy is that surrogate mothers may be exploited by being given too little compensation. However, the possibility of exploitation is a weak argument for prohibition, as employment alternatives for potential surrogate mothers may be more exploitative or more harmful than surrogacy. It is concluded that international surrogacy must be regulated, and the proposed regulatory mechanism is termed Fair Trade Surrogacy. The guidelines of Fair Trade Surrogacy focus on minimizing potential harms to all parties and ensuring fair compensation for surrogate mothers. (shrink)

Psychology without genuinely thoughtful philosophy winds up as self-help gimmicks; philosophy without the insights & feeling of psychology remains an arcane academic game out of touch with life. By re-joining spirit & soul, this book is a major work of both philosophy & psychology. Casey asks puzzling questions & gives lasting answers. In a clear & vivid manner, one of America's best professional thinkers takes up one of the great themes of imagination, fantasy, hallucination, remembering & perceiving. Film & (...) architecture provide surprising material for his brilliant & useful account of basic philosophical problems which are also major mysteries of the soul. (shrink)

Through extensive training, experts acquire specialized knowledge and abilities. In this paper, I argue that experts also acquire specialized visual experiences. Specifically, I articulate and defend the account that experts enjoy visual experiences that represent gestalt properties through perceptual learning. I survey an array of empirical studies on face perception and perceptual expertise that support this account. I also look at studies on perceptual adaptation that some might argue present a problem for my account. I show how the data are (...) subject to an interpretation that is friendly to it. Last, I address two theoretical objections to the claim that visual experiences represent gestalt properties. (shrink)

Barz (2018) contends that there is no specification of the phenomenon of first-person authority that avoids falsity or triviality. This paper offers one. When a subject self-ascribes a current conscious mental state in speech, there is a presumption that what she says is true. To defeat this presumption, one must be able to explain how she has been led astray.

Among philosophical analyses of Darwin’s Origin, a standard view says the theory presented there had no concrete observational consequences against which it might be checked. I challenge this idea with a new analysis of Darwin’s principal geographical distribution observations and how they connect to his common ancestry hypothesis.

Innovative research on decision making under ‘deep uncertainty’ is underway in applied fields such as engineering and operational research, largely outside the view of normative theorists grounded in decision theory. Applied methods and tools for decision support under deep uncertainty go beyond standard decision theory in the attention that they give to the structuring of decisions. Decision structuring is an important part of a broader philosophy of managing uncertainty in decision making, and normative decision theorists can both learn from, and (...) contribute to, the growing deep uncertainty decision support literature.

Educators are increasingly concerned with the use of artificial intelligence (AI) in student writing. Much of the concern focuses on the issue of students using ChatGPT to complete their work. I introduce the CUPID model for instructors to use when thinking about how to pedagogically handle ChatGPT. The CUPID model lays out five general approaches: Catch, Utilize, Prevent, Ignore, and Disincentivize. I suggest that instructors should especially consider using certain assignments that fall under the approach “Disincentivize”. Philosophy instructors in particular (...) should assign more low-stakes writing, such as journals and reflection pieces. The adoption of low-stakes writing assignments aims to discourage students from relying on AI while promoting clarity of thought and deeper engagement with philosophical ideas. (shrink)

Kriegel has recently developed an adverbial account of intentionality, in part to solve the problem of how we can think of non-existents. The view has real virtues: it endorses a non-relational conception of intentionality and is ontologically conservative. Alas, the view ultimately cannot replace the act-object model of intentionality that it seeks to, because it depends on the act-object model for its intelligibility at key points. It thus fails as a revisionistic theory. I argue that the virtues of adverbialism can (...) be had from within the act-object framework, provided we understand intentional objects correctly. I use Crane as a guide here, and build on his work on intentional objects. In the end, we can provide a suitable solution to the problem of thinking of non-existents within the act-object framework without adopting implausible ontological or metaphysical views. So, adverbialism is neither a possible stand-alone revisionary option nor a needed modif... (shrink)

Dystopian and postapocalyptic narratives are often vectors for utopian hope in decidedly anti-utopian historical moments. The twenty-first century has, arguably, been such a moment. The association of utopianism with some of the most devastating political projects of the twentieth century, the plurality of existential threats looming over the globalized world, and the hegemony of global capitalism converge to form a cultural milieu inundated with grim visions of the future. These visions, however, have a stubborn tendency to gesture toward their negation: (...) the emancipated society. Optimism and pessimism are intermingled in contemporary narratives that frame the end of civilization as the precondition for a utopian... (shrink)

In the heart of southeast Texas, an industrial powerhouse often referred to as the 'Golden Triangle', the oil refineries and petrochemical plants stand as stalwart testaments to the region's economic evolution. Interestingly, before the discovery of oil at Spindletop, the lumber and cattle industries powered this region's economy. A profound shift occurred when the Lucas Gusher, a fountain of oil spurting thousands of feet into the air, struck the lands of Spindletop Hill on January 10, 1901. This remarkable discovery of (...) the Spindletop oilfield on a slat dome formation south of Beaumont, Texas, marked the birth of the modern petroleum industry and fundamentally transformed the region's geopolitical, economic, and cultural landscapes. People from all over the country relocated to Gladys City and Beaumont in search of work and new opportunities, creating a boomtown as the town's population swelled from 10,000 to 50,000. The newfound urbanization brought by the oil industry transformed the town and the surrounding areas, creating a ripple effect across the region that would be felt for generations to come. The surge in oil-driven economic activity transmuted the region into a vibrant nexus of commerce, with the oil industry emerging as a critical architect of growth and advancement. This newfound affluence incited by the petroleum sector ushered in an era of economic diversification, laying the groundwork for industrialization’s further evolution. The Spindletop Oil Fields not only underscored the United States’ ascent as the foremost petroleum-producing nation but also signaled the nation’s initiation into the Petroleum Age. It was Spindletop that solidified its position as America’s first significant oil field, becoming an enduring symbol of its industrial might. By 1985, over 153,000,000 barrels of oil had been produced and extracted from the Spindletop oil fields, underscoring the magnitude of this extraordinary resource. (shrink)

The Centers for Medicare & Medicaid Services has initiated bundled payments for hip and knee total joint replacement in an effort to decrease healthcare costs and increase quality of care. The ethical implications of this program have not been studied. This article considers the ethics of patient selection to improve outcomes; specifically, screening patients by body mass index to determine eligibility for total joint replacement. I argue that this type of screening is not ethically defensible, and that the bundled payment (...) program as structured is likely to lead to unfair restrictions on who receives total joint replacements.

Linda Zagzebski makes a compelling and many-faceted case for the primacy of virtue in both epistemology and ethics, and for the thesis that "epistemic evaluation just is a form of moral evaluation". Along the way, she explores a variety of theoretical problems in both ethics and epistemology, advancing promising new analyses and solutions. For a work of contemporary epistemology, Virtues of the Mind is uncommonly readable, relevant, and historically informed—and Zagzebski manages all this without sacrificing depth or rigor. Specialists and (...) nonspecialists alike will find it a rewarding study. (shrink)

Pessimists about moral testimony hold that there is something suboptimal about forming moral beliefs by deferring to another. This paper motivates an analogous claim about self-knowledge of the reason-responsive attitudes. When it comes to your own mind, it seems important to know things “from the inside”, in the first-personal way, rather than putting your trust in another. After motivating Pessimism, the paper offers an explanation of its truth. First-person knowledge is distinctive because it involves knowing a state of mind and (...) finding it intelligible from one’s point of view. It concludes by considering the value of this form of self-understanding. (shrink)

As our scientific and technical abilities expand at breathtaking speeds, concern that modern genetics and bioengineering are leading us to a posthuman future is growing. Is Human Nature Obsolete? poses the overarching question of what it is to be human against the background of these current advances in biotechnology. Its perspective is philosophical and interdisciplinary rather than technical; the focus is on questions of fundamental ontological importance rather than the specifics of medical or scientific practice.The authors -- all distinguished scholars (...) in their fields -- take on questions about technology's goals and values that are often ignored or sidelined in the face of rapid scientific advances and the highly specialized nature of technical knowledge. The essays included represent a rich variety of thought, ranging from finely nuanced philosophical and theological arguments to historical studies and cultural commentaries. Several explore the historical background of today's biotechnology: Timothy Casey traces such developments as the emergence of cybernetic humanity from Cartesian dualism, and Diane Paul presents the history of "positive" versus coerced eugenics. Jean Bethke Elshtain discusses cloning as a "messianic project" to perfect the body and exclude natural diversity -- giving as an example the elimination of Down Syndrome as an acceptable human type -- while Harold Baillie calls for an examination of the metaphysical roots of personhood. Robert Proctor finds no evidence in paleontology for any "essence of humanity," and Tom Shannon argues against materialist reductionism. Addressing social concerns, Lisa Sowle Cahill finds the possibility of a political solution to the problems raised by genetic engineering in Catholic teachings on social justice, and Langdon Winner looks critically at the "scientific enthusiasts of a posthuman future." Taken as a whole, the book provides a humanistic overview of a subject too often considered only in its technological aspect. (shrink)

Marina Sbisà’s remarks on illocutionary pluralism suggest but do not constitute a full-blown theory. In this chapter I discuss two different attempts to build on those remarks. The first, illocutionary relativism, is my own attempt to develop the ideas presented in Sbisà’s remarks. The second, from Marcin Lewiński, differs in important ways. I then briefly compare these two varieties of illocutionary pluralism.

This is the first volume dedicated solely to the topic of epistemological disjunctivism. The original essays in this volume, written by leading and up-and-coming scholars on the topic, are divided into three thematic sections. The first set of chapters addresses the historical background of epistemological disjunctivism. It features essays on ancient epistemology, Immanuel Kant, J.L. Austin, Edmund Husserl, and Ludwig Wittgenstein. The second section tackles a number contemporary issues related to epistemological disjunctivism, including its relationship with perceptual disjunctivism, radical skepticism, (...) and reasons for belief. Finally, the third group of essays extends the framework of epistemological disjunctivism to other forms of knowledge, such as testimonial knowledge, knowledge of other minds, and self-knowledge. Epistemological Disjunctivism is a timely collection that engages with an increasingly important topic in philosophy. It will appeal to researches and graduate students working in epistemology, philosophy of mind, and philosophy of perception. (shrink)

At the center of much contemporary work on self-knowledge of our attitudes is a debate between Agentialists and Empiricists. Empiricists hold that first-person knowledge of one’s own attitudes possesses a broadly empirical basis, such as observation or inference. Agentialists insist that an account of self-knowledge must make sense of the intimate connection between knowing one’s attitudes and actively forming them in response to reasons. But it is plausible to suppose that a psychologically realistic account of self-knowledge will emphasize both active (...) and passive elements. Focusing on the idea that we form self-ascriptions of belief on the basis of active deliberation, this paper outlines such a middle ground position. (shrink)

Reports of the Intergovernmental Panel on Climate Change (IPCC) employ an evolving framework of calibrated language for assessing and communicating degrees of certainty in findings. A persistent challenge for this framework has been ambiguity in the relationship between multiple degree-of-certainty metrics. We aim to clarify the relationship between the likelihood and confidence metrics used in the Fifth Assessment Report (2013), with benefits for mathematical consistency among multiple findings and for usability in downstream modeling and decision analysis. We discuss how our (...) proposal meshes with current and proposed practice in IPCC uncertainty assessment. (shrink)

Following a synthesis of naturalistic and experimental studies of language creation, we propose a theoretical model that describes the process through which human communication systems might arise and evolve. Three key processes are proposed that give rise to effective, efficient and shared human communication systems: motivated signs that directly resemble their meaning facilitate cognitive alignment, improving communication success; behavioral alignment onto an inventory of shared sign-to-meaning mappings bolsters cognitive alignment between interacting partners; sign refinement, through interactive feedback, enhances the efficiency (...) of the evolving communication system. By integrating the findings across a range of diverse studies, we propose a theoretical model of the process through which the earliest human communication systems might have arisen and evolved. Importantly, because our model is not bound to a single modality it can describe the creation of shared sign systems across a range of contexts, informing theories of language creation and evolution.

Suppose I make an utterance, intending it to be a command. You don’t take it to be one. Must one of us be wrong? In other words, must each utterance have, at most, one illocutionary force? Current debates over the constitutive norm of assertion and over illocutionary silencing, tend to assume that the answer is yes—that each utterance must be either an assertion, or a command, or a question, but not more than one of these. While I think that this (...) assumption is intuitive, I will argue in this paper that it is not sustainable. I’ll argue that this assumption makes it hard to explain what determines illocutionary force in a consistent and non-ad hoc way. I will demonstrate this is not fatal for the notion of illocutionary force writ large by offering some alternatives. (shrink)
