We motivate the desire for self-driving and explain its potential and limitations, and explore the need for—and potential implementation of—morals, ethics, and other value systems as complementary “capabilities” to the Deep Technologies behind self-driving. We consider how the incorporation of such systems may drive or slow adoption of high automation within vehicles. First, we explore the role for morals, ethics, and other value systems in self-driving through a representative hypothetical dilemma faced by a self-driving car. Through the lens of engineering, (...) we explain in simple terms common moral and ethical frameworks including utilitarianism, deontology, and virtue ethics before characterizing their relationship to the fundamental algorithms enabling self-driving. The concepts of behavior cloning, state-based modeling, and reinforcement learning are introduced, with some algorithms being more suitable for the implementation of value systems than others. We touch upon the contemporary cross-disciplinary landscape of morals and ethics in self-driving systems from a joint philosophical and technical perspective, and close with considerations for practitioners and the public, particularly as individuals may not appreciate the nuance and complexity of using imperfect information to navigate diverse scenarios and tough-to-quantify value systems, while “typical” software development reduces complex problems to black and white decision-making.

My replies to Errol Lord, Adam Pautz, and Peter Railton's commentaries on The Rationality of Perception (2017).

What do we see? We are visually conscious of colors and shapes, but are we also visually conscious of complex properties such as being John Malkovich? In this book, Susanna Siegel develops a framework for understanding the contents of visual experience, and argues that these contents involve all sorts of complex properties. Siegel starts by analyzing the notion of the contents of experience, and by arguing that theorists of all stripes should accept that experiences have contents. She then (...) introduces a method for discovering the contents of experience: the method of phenomenal contrast. This method relies only minimally on introspection, and allows rigorous support for claims about experience. She then applies the method to make the case that we are conscious of many kinds of properties, of all sorts of causal properties, and of many other complex properties. She goes on to use the method to help analyze difficult questions about our consciousness of objects and their role in the contents of experience, and to reconceptualize the distinction between perception and sensation. Siegel's results are important for many areas of philosophy, including the philosophy of mind, epistemology, and the philosophy of science. They are also important for the psychology and cognitive neuroscience of vision. (shrink)

I distinguish between two kinds of selection effects on experience: selection of objects or features for experience, and anti-selection of experiences for cognitive uptake. I discuss the idea that both kinds of selection effects can lead to a form of confirmation bias at the level of perception, and argue that when this happens, selection effects can influence the rational role of experience.

Siegel and Byrne debate whether perceptual experiences present rich properties or exclusively thin properties.

An overview of the epistemology of perception, covering the nature of justification, immediate justification, the relationship between the metaphysics of perceptual experience and its rational role, the rational role of attention, and cognitive penetrability. The published version will contain a smaller bibliography, due to space constraints in the volume.

In this paper I offer a theory of what makes certain influences on visual experiences by prior mental states (including desires, beliefs, moods, and fears) reduce the justificatory force of those experiences. The main idea is that experiences, like beliefs, can have rationally assessable etiologies, and when those etiologies are irrational, the experiences are epistemically downgraded.

I discuss the roles of journalism in aspirational democracies, and argue that they generate set of pressures on attention that apply to people by virtue of the type of society they live in. These pressures, I argue, generate a problem of democratic attention: for journalism to play its roles in democracy, the attentional demands must be met, but there are numerous obstacles to meeting them. I propose a principle of salience to guide the selection and framing of news stories that (...) I argue may help address the puzzle: the public-as-protagonist principle. -/- . (shrink)

Is 'education' a thick epistemic concept? The answer depends, of course, on the viability of the 'thick/thin' distinction, as well as the degree to which education is an epistemic concept at all. I will concentrate mainly on the latter, and will argue that epistemological matters are central to education and our philosophical thinking about it; and that, insofar, education is indeed rightly thought of as an epistemic concept. In laying out education's epistemological dimensions, I hope to clarify the degree to (...) which it makes sense to regard the concept as 'thick'. I also discuss the relationship between philosophy of education and virtue epistemology and the sense in which being educated might itself be thought to be an epistemic virtue. Finally, I urge virtue epistemologists in particular and epistemologists generally to turn their attention to questions of education, to further both the philosophy of education and epistemology itself.

It is well known that the nature of consciousness is elusive, and that attempts to understand it generate problems in metaphysics, philosophy of mind, psychology, and neuroscience. Less appreciated are the important – even if still elusive – connections between consciousness and issues in ethics. In this chapter we consider three such connections. First, we consider the relevance of consciousness for questions surrounding an entity’s moral status. Second, we consider the relevance of consciousness for questions surrounding moral responsibility for action. (...) Third, we consider the relevance of consciousness for the acquisition of moral knowledge. (shrink)

Consider the following explanation: (1) George took his umbrella because it was just about to rain. This is an explanation of a quite distinctive sort. It is profoundly different from the sort of explanation we might use to explain, say, the movements of a bouncing ball or the gradual rise of the tide on a beach. Unlike these other types of explanations, it explains an agent’s behavior by describing the agent’s own _reasons_ for performing that behavior. Explanations that work in (...) this way have a number of distinctive and important properties, and we will refer to them here as _reason explanations_. Looking at the use of reason explanations with a philosophical eye, one is apt to experience a certain puzzlement. One wants to know precisely what makes a given reason explanation true or false. So, for example, the explanation given above seems to be saying that George’s reason for taking his umbrella was that it was just about to rain. But what exactly makes it the case that this is George’s reason? Does he have to actually be. (shrink)

Advocates of the use of intuitions in philosophy argue that they are treated as evidence because they are evidential. Their opponents agree that they are treated as evidence, but argue that they should not be so used, since they are the wrong kinds of things. In contrast to both, we argue that, despite appearances, intuitions are not treated as evidence in philosophy whether or not they should be. Our positive account is that intuitions are a subclass of inclinations to believe. (...) Our thesis explains why intuitions play a role in persuasion and inquiry, without conceding that they are evidential. The account also makes predictions about the structure of intuitions that are confirmed by independent arguments. (shrink)

Our brains were designed for tribal life, for getting along with a select group of others and for fighting off everyone else. But modern times have forced the world’s tribes into a shared space, resulting in epic clashes of values along with unprecedented opportunities. As the world shrinks, the moral lines that divide us become more salient and more puzzling. We fight over everything from tax codes to gay marriage to global warming, and we wonder where, if at all, we (...) can find our common ground. (shrink)

There are several important arguments in metaethics that rely on explanatory considerations. Gilbert Harman has presented a challenge to the existence of moral facts that depends on the claim that the best explanation of our moral beliefs does not involve moral facts. The Reliability Challenge against moral realism depends on the claim that moral realism is incompatible with there being a satisfying explanation of our reliability about moral truths. The purpose of this chapter is to examine these and related arguments. (...) In particular, this chapter will discuss four kinds of arguments – Harman’s Challenge, evolutionary debunking arguments, irrelevant influence arguments, and the Reliability Challenge – understood as arguments against moral realism. The main goals of this chapter are (i) to articulate the strongest version of these arguments; (ii) to present and assess the central epistemological principles underlying these arguments; and (iii) to determine what a realist would have to do to adequately respond to these arguments.

The correspondence theory of truth is a precise and innovative account of how the truth of a proposition depends upon that proposition's connection to a piece of reality. Joshua Rasmussen refines and defends the correspondence theory of truth, proposing new accounts of facts, propositions, and the correspondence between them. With these theories in hand, he then offers original solutions to the toughest objections facing correspondence theorists. Addressing the Problem of Funny Facts, Liar Paradoxes, and traditional epistemological questions concerning how (...) our minds can access reality, he challenges recent objections, and defends what has traditionally been the most popular theory of truth. Written with clarity, precision, and sensitivity to a range of philosophical backgrounds, his book will appeal to advanced students and scholars seeking a deeper understanding of the relationship between truth and reality.

This chapter examines when a word’s meaning can change. On the view explored here, the meaning of a term is fixed by language users having certain dispositions to use the term in certain ways. Consequently, meanings change—concepts shift—when the relevant dispositions change. After the view is articulated, it is put to use defending descriptivism from some recent objections. Finally, this chapter examines the extent to which terms really replace meanings at all—conceptual revolution—or just have their meanings and references change shape—conceptual (...) evolution.

Are properties perfectly natural (or not) relative to worlds, or are they perfectly natural (or not) tout court? That is, could there be a property P that is instanti-ated at worlds w1 and w2, and is perfectly natural at w1 but not at w2? Here, we offer an original argument for the non-world-relativity of perfect naturalness. Along the way, we reply to a prima facie compelling argument for the contin-gency of perfect naturalness, based upon the connection between natural prop-erties and (...) laws of nature. (shrink)

‘Argument’ has multiple meanings and referents in contemporary argumentation theory. Theorists are well aware of this but often fail to acknowledge it in their theories. In what follows, I distinguish several senses of ‘argument’ and argue that some highly visible theories are largely correct about some senses of the term but not others. In doing so, I hope to show that apparent theoretical rivals are better seen as collaborators or partners, rather than rivals, in the multi-disciplinary effort to understand ‘argument,’ (...) arguments, and argumentation in all their varieties. I argue as well for a pluralistic approach to argument evaluation and argumentative norms, since arguments and argumentation can be legitimately evaluated along several dimensions, but urge that epistemic norms enjoy conceptual priority.

We think of logic as objective. We also think that we are reliable about logic. These views jointly generate a puzzle: How is it that we are reliable about logic? How is it that our logical beliefs match an objective domain of logical fact? This is an instance of a more general challenge to explain our reliability about a priori domains. In this paper, I argue that the nature of this challenge has not been properly understood. I explicate the challenge (...) both in general and for the particular case of logic. I also argue that two seemingly attractive responses – appealing to a faculty of rational insight or to the nature of concept possession – are incapable of answering the challenge. (shrink)

We chart how neuroscience and philosophy have together advanced our understanding of moral judgment with implications for when it goes well or poorly. The field initially focused on brain areas associated with reason versus emotion in the moral evaluations of sacrificial dilemmas. But new threads of research have studied a wider range of moral evaluations and how they relate to models of brain development and learning. By weaving these threads together, we are developing a better understanding of the neurobiology of (...) moral judgment in adulthood and to some extent in childhood and adolescence. Combined with rigorous evidence from psychology and careful philosophical analysis, neuroscientific evidence can even help shed light on the extent of moral knowledge and on ways to promote healthy moral development.

One of the most influential methodological contributions of twentieth‐century philosophy was the approach known as conceptual analysis. The majority of experimental philosophy papers are doing cognitive science. They are revealing surprising new effects and then offering explanations those effects in terms of certain underlying cognitive processes. The best way to get a sense for actual research programs in experimental philosophy is to look in detail at one particular example. This chapter considers the effect of moral considerations on intuitions about intentional (...) action, as an example. Working in conceptual analysis aimed to develop analyses of concepts, and in that context, the obvious proposal would be that people should be aiming for simple analyses of concepts. The chapter also focuses on the study of intuitions about knowledge. Experimental philosophy has sought to capture the patterns in people's intuitions through theories about underlying cognitive processes. (shrink)

A summary of The Rationality of Perception, and my replies to symposium papers on it by Andy Clark and Christopher Peacocke.

Duncan Purves and Nicolas Delon have argued that one’s life will be meaningful to the extent that one contributes to valuable states of affairs and this contribution is a result of one’s intentional actions. They then argue, contrary to some theorists’ intuitions, that non-human animals are capable of fulfilling these requirements, and that this finding might entail important things for the animal ethics movement. In this paper, I also argue that things besides human beings can have meaningful existences, but I (...) disagree with Purves and Delon’s theory of meaning, and some of the practical implications they suggest arise from their conclusion. Specifically, I argue that Purves and Delon are wrong to suggest that intentional agency is necessary for one’s life to be meaningful; contributing to valuable states of affairs can be sufficient by itself. Purves and Delon’s objection to such a claim is that it would allow even inanimate objects’ existences to count as meaningful. However, while I accept this... (shrink)

What does it mean to look? How does looking relate to damage? These are the fundamental questions addressed in Overlooking Damage. From the Roman triumph to the iconoclasm of ISIS and the Taliban to the aerial views of looted landscapes and destroyed temples visible on Google, the relationship between beauty and violence is far more intimate than we sometimes acknowledge. Jonah Siegel makes the daring argument that a thoughtful reaction to images of damage need not stop at melancholy, but (...) can lead us to a new reckoning. Would the objects we admire be more beautiful if they were not injured or displaced, if they did not remind us of unbearable violence? Siegel takes up writers from the time of the French Revolution to today who have reacted to the depredations of revolutionary iconoclasm, colonial looting, and industrial capitalism, and proposes that in these authors we may find resources with which to navigate our contemporary situation. Deftly bringing the methods of literary studies to bear on important debates in the study of heritage, archaeology, and visual culture, Overlooking Damage reflects on the ways in which concepts of beauty intersect with periods of epochal violence in an attempt to resist the separation of broken things from the worlds in which they have come to be embedded.

This first anthology of the most important writings by Danny Siegel, spanning and modernizing fifty years of his insights, Radiance intersperses soulful Jewish texts with innovative Mitzvah ideas to rouse individuals and communities to transform our lives, communities, and world.

_Hailed by the _New York Times_ as a book that “examines the role that argument has played throughout history and how it has shaped human existence”__ “An invigorating reflection on the nature and value of disagreement.... Sharp and taut.... A lesson in a well-constructed argument itself.”—_Publishers Weekly_, starred review__ “Perhaps more than any other commentary, _Why Argument Matters_ illuminates the root causes of our partisan, venomous, irrational times—and yet somehow rescues from the morass the true nature of argument, its power (...) and beauty.”—Michael Wolff, author of ___Fire and Fury: Inside the Trump White House__ From Eve’s crafty exchange with the serpent, to Martin Luther King Jr.’s soaring, subtle ultimatums, to the throes of Twitter—argument’s drainpipe—the human desire to prevail with words has been not just a moral but an existential compulsion. In this dazzling reformulation of argument, renowned critic Lee Siegel portrays the true art of argument as much deeper and far more embracing than mere quarrel, dispute, or debate. It is the supreme expression of humanity’s longing for a better life, born of empathy and of care for the world and those who inhabit it. With wit, passion, and striking insights, Siegel plumbs the emotional and psychological sources of clashing words, weaving through his exploration the untold story of the role argument has played in societies throughout history. Each life, he maintains, is an argument for that particular way of living; every individual style of argument is also a case that is being made for that person’s right to argue. Argument is at the heart of the human experience, and language, at its most liberated and expressive, inexorably bends toward argument. (shrink)

This chapter discusses epistemic objections to non-naturalist moral realism. The goal of the chapter is to determine which objections are pressing and which objections can safely be dismissed. The chapter examines five families of objections: (i) one involving necessary conditions on knowledge, (ii) one involving the idea that the causal history of our moral beliefs reflects the significant impact of irrelevant influences, (iii) one relying on the idea that moral truths do not play a role in explaining our moral beliefs, (...) (iv) one involving the claim that if moral realism is true then our moral beliefs are unlikely to be reliable, and (v) one involving the claim that moral realism is incompatible with there being a plausible explanation of our reliability about morality. The overall conclusion of the chapter is that the final objection is by far the most pressing. (shrink)

In his writing, Gilles Deleuze drew on a vast array of source material, from philosophy and psychoanalysis to science and art. Yet scholars have largely neglected one of the intellectual currents underlying his work: Western esotericism, specifically the lineage of hermetic thought that extends from Late Antiquity into the Renaissance through the work of figures such as Iamblichus, Nicholas of Cusa, Pico della Mirandola, and Giordano Bruno. In this book, Joshua Ramey examines the extent to which Deleuze's ethics, metaphysics, (...) and politics were informed by, and can only be fully understood through, this hermetic tradition. Identifying key hermetic moments in Deleuze's thought, including his theories of art, subjectivity, and immanence, Ramey argues that the philosopher's work represents a kind of contemporary hermeticism, a consistent experiment in unifying thought and affect, percept and concept, and mind and nature in order to engender new relations between knowledge, power, and desire. By uncovering and clarifying the hermetic strand in Deleuze's work, Ramey offers both a new interpretation of Deleuze, particularly his insistence that the development of thought demands a spiritual ordeal, and a framework for retrieving the pre-Kantian paradigm of philosophy as spiritual practice.

This paper is a discussion note on Isaacs et al. (2022), who have claimed to offer a new motivation for imprecise probabilities, based on the mathematical phenomenon of non-measurability. In this note, I clarify some consequences of their proposal. In particular, I show that if their proposal is applied to a bounded 3-dimensional space, then they have to reject at least one of the following: (i) If A is at most as probable as B and B is at most as (...) probable as C, then A is at most as probable as C. (ii) Let A ∩ C = B ∩ C = ∅. A is at most as probable as B iff (A ∪ C) is at most as probable as (B ∪ C). But rejecting either statement seems unattractive. (shrink)

While developments of a shared intellectual tradition, the enactivist approach and the organizational account proffer importantly different accounts of organismic normativity. Where enactivists tend to follow Hans Jonas, Andres Weber, and Francisco Varela in grounding intrinsic affordance norms in existential concern, organizational theorists such as Alvaro Moreno, Matteo Mossio, and Leonardo Bich seek a more deflationary account of these normative phenomena. Critiques directed at both of these accounts of organismic normativity motivate the introduction of the precedential account of organismic normativity, (...) which I nevertheless locate within the enactivist approach, broadly construed. After detailing empirical evidence that would seem to vindicate the precedential account, I explore some of its implications. (shrink)

Are there any things that are such that any things whatsoever are among them. I argue that there are not. My thesis follows from these three premises: (1) There are two or more things; (2) for any things, there is a unique thing that corresponds to those things; (3) for any two or more things, there are fewer of them than there are pluralities of them.

Experimental philosophy uses experimental research methods from psychology and cognitive science in order to investigate both philosophical and metaphilosophical questions. It explores philosophical questions about the nature of the psychological world - the very structure or meaning of our concepts of things, and about the nature of the non-psychological world - the things themselves. It also explores metaphilosophical questions about the nature of philosophical inquiry and its proper methodology. This book provides a detailed and provocative introduction to this innovative field, (...) focusing on the relationship between experimental philosophy and the aims and methods of more traditional analytic philosophy. Special attention is paid to carefully examining experimental philosophy's quite different philosophical programs, their individual strengths and weaknesses, and the different kinds of contributions that they can make to our philosophical understanding. Clear and accessible throughout, it situates experimental philosophy within both a contemporary and historical context, explains its aims and methods, examines and critically evaluates its most significant claims and arguments, and engages with its critics.

The rhetoric of disgust is common in moral discourse and political propaganda. Some believe it's pernicious, for it convinces without evidence. But scientific research now suggests that disgust is typically an effect, not a cause, of moral judgment. At best the emotion on its own only sometimes slightly amplifies a moral belief one already has. Appeals to disgust are thus dialectically unhelpful in discourse that seeks to convince. When opponents of abortion use repulsive images to make their case, they convince (...) few, even if they rally their base. When champions of animal rights show graphic depictions of the torturous conditions of animals in factory farms, they convince only those previously ignorant of the severity of such conditions. Ultimately, disgust may be less pernicious than it is useless. (shrink)

It has been standard philosophical practice in analytic philosophy to employ intuitions generated in response to thought-experiments as evidence in the evaluation of philosophical claims. In part as a response to this practice, an exciting new movement—experimental philosophy—has recently emerged. This movement is unified behind both a common methodology and a common aim: the application of methods of experimental psychology to the study of the nature of intuitions. In this paper, we will introduce two different views concerning the relationship that (...) holds between experimental philosophy and the future of standard philosophical practice (what we call, the proper foundation view and the restrictionist view), discuss some of the more interesting and important results obtained by proponents of both views, and examine the pressure these results put on analytic philosophers to reform standard philosophical practice. We will also defend experimental philosophy from some recent objections, suggest future directions for work in experimental philosophy, and suggest what future lines of epistemological response might be available to those wishing to defend analytic epistemology from the challenges posed by experimental philosophy.
