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)

There is an important division in the human mind between perception and reasoning. We reason from information that we have already, but perception is a means of taking in new information. Susanna Siegel argues that these two aspects of the mind become deeply intertwined when beliefs, fears, desires, or prejudice influence what we perceive.

What is involved in acquiring a new dialect - for example, when Canadian English speakers move to Australia or African American English-speaking children go to school? How is such learning different from second language acquisition, and why is it in some ways more difficult? These are some of the questions Jeff Siegel examines in this book, which focuses specifically on second dialect acquisition. Siegel surveys a wide range of studies that throw light on SDA. These concern dialects of (...) English as well as those of other languages, including Dutch, German, Greek, Norwegian, Portuguese and Spanish. He also describes the individual and linguistic factors that affect SDA, such as age, social identity and language complexity. The book discusses problems faced by students who have to acquire the standard dialect without any special teaching, and presents some educational approaches that have been successful in promoting SDA in the classroom.

In Educating Reason, Harvey Siegel presented the case regarding rationality and critical thinking as fundamental education ideals. In Rationality Redeemed? , a collection of essays written since that time, he develops this view, responds to major criticisms raised against it, and engages those critics in dialogue. In developing his ideas and responding to critics, Siegel addresses main currents in contemporary thought, including feminism, postmodernism and multiculturalism.

In this paper I argue that it's possible that the contents of some visual experiences are influenced by the subject's prior beliefs, hopes, suspicions, desires, fears or other mental states, and that this possibility places constraints on the theory of perceptual justification that 'dogmatism' or 'phenomenal conservativism' cannot respect.

Beginning with a discussion of the Informal Logic Movement and the renewed interest in critical thinking in education, this book critically assesses the work of Robert Ennis, Richard Paul and John McPeck.

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)

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

I analyze a type of practice related to inquiry: treating things as zetetically relevant to questions, and argue that this practice is a central normatively evaluable way to extend lines of inquiry. My strategy is to introduce the practice and its normative features by examining its relationship to something already well-understood: the ways that news stories produced by journalists frame events. I then argue that the same core zetetic practice can be found across domains, just not in journalism. Finding the (...) same practice across such different human settings suggests it is a core feature of inquiry. (shrink)

The phylogenetic data are inconsistent with the hypothesis that REM sleep duration is correlated with learning or learning ability. Humans do not have uniquely high amounts of REM sleep. The platypus, marsupials, and other mammals not generally thought to have extraordinary learning abilities have the largest amounts of REM sleep. The whales and dolphins (cetaceans) have the lowest amounts of REM sleep and may go without REM sleep for extended periods of time, despite their prodigious learning abilities. Vertes & Eastman].

A short overview of the philosophical significance of perceptual contents.

This paper defends the Content View: the thesis that all visual experiences have contents.

Inquiry is guided, in the minimal sense that it is not haphazard. It is also often thought to have as a natural stopping point ceasing to inquire, once inquiry into a question yields knowledge of an answer. On this picture, inquiry is both telic and guided. By contrast, mind-wandering is unguided and atelic, according to the most extensively developed philosophical theory of it. This paper articulates a puzzle that arises from this combination of claims: there seem to be plenty of (...) examples of inquiry progressing within mind-wandering, yet theories of inquiry and mind-wandering can make wandering inquiry seem impossible or incoherent. I offer several solutions to this puzzle and make the case that taken together, they illuminate a prevalent form of inquiry that the burgeoning literature on that topic overlooks: inquiry that progresses spontaneously.

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

In Biro and Siegel we argued that a theory of argumentation mustfully engage the normativity of judgments about arguments, and we developedsuch a theory. In this paper we further develop and defend our theory.

In light of recent criticisms by Woodward (2017) and Rescorla (2018), we examine the relationship between mechanistic explanation and phenomenological laws. We disambiguate several uses of the phrase “phenomenological law” and show how a mechanistic theory of explanation sorts them into those that are and are not explanatory. We also distinguish the problem of phenomenological laws from arguments about the explanatory power of purely phenomenal models, showing that Woodward and Rescorla conflate these problems. Finally, we argue that the temptation to (...) pit mechanistic and interventionist theories of explanation against one another occludes important and scientifically relevant research questions.

Perceptual learning is characterized by long-term changes in perception as a result of practice or experience. In this paper, I argue that through perceptual learning we can become newly sensitive to basic perceptual features. First, I provide a novel account of basic perceptual features. Then, I argue that evidence from experience-based plasticity suggests that basic perceptual features can be learned. Lastly, I discuss the common scientific and philosophical view that perceptual learning comes in at least four varieties: differentiation, unitization, attentional (...) weighting and stimulus imprinting (Goldstone 1998, Connolly 2019). Becoming newly sensitive to basic perceptual features, I argue, does not fit into any of these categories. This paper’s contribution to the literature is twofold. First, I present a novel view of basic perceptual features which can be used in subsequent theorizing. Second, I show that learning basic perceptual features, since it does not fit into this standardized taxonomy, constitutes an underappreciated form of perceptual learning. This result has important implications for recent discussions in the philosophy of perception and epistemology. (shrink)

Some have defended a Fregean view of perceptual content. On this view, the constituents of perceptual contents are Fregean modes of presentation (MOPs). In this paper, I propose that perceptual MOPs are best understood in terms of object files. Object files are episodic representations that store perceptual information about objects. This information is updated when sensory conditions change. On the proposed view, when a subject perceptually represents some object a under two distinct MOPs, then the subject initiates two object files (...) that both refer to a. My defense of this view appeals to its satisfaction of four constraints that I argue theories of perceptual MOPs should satisfy. Furthermore, I show that some existent accounts of perceptual MOPs fail to satisfy them. The defended constraints also indicate what is unique about perceptual, as opposed to linguistic or cognitive, MOPs. (shrink)

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.

Education's Epistemology extends and defends Siegel's "reasons conception" of critical thinking, developing it in both philosophical and educational directions. Of particular note is its emphasis on epistemic quality and epistemic rationality and its concerted defense of "universal" educational and philosophical ideals in the face of multicultural, postmodern, and other challenges.

‘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.

In discussions of perception and its relation to knowledge, it is common to distinguish what one comes to believe on the basis of perception from the distinctively perceptual basis of one's belief. The distinction can be drawn in terms of propositional contents: there are the contents that a perceiver comes to believe on the basis of her perception, on the one hand; and there are the contents properly attributed to perception itself, on the other. Consider the content.

When does a model explain? When does it promote understanding? A dominant approach to scientific explanation is the interventionist view. According to this view, when X explains Y, intervening on X can produce, prevent or alter Y in some predictable way. In this paper, I argue for two claims. First, I reject a position that many interventionist theorists endorse. This position is that to explain some phenomenon by providing a model is also to understand that phenomenon. While endorsing the interventionist (...) view, I argue that explaining and understanding are distinct scientific achievements. Second, I defend a novel theory of scientific understanding. According to this view, when some model M promotes understanding, M makes available a distinctive mental state. This state is of the same psychological kind as when we grasp events in a narrative as bearing on some ultimate conclusion. To conclude, I show that, given this view, mechanistic explanations often provide a powerful source of understanding that many causal-historical models lack. This paper will be of interest to both philosophers of science and epistemologists engaged in the topics of explanation and understanding. (shrink)

Can perceptual experiences be states of uncertainty? We might expect them to be, if the perceptual processes from which they're generated, as well as the behaviors they help produce, take account of probabilistic information. Yet it has long been presumed that perceptual experiences purport to tell us about our environment, without hedging or qualifying. Against this long-standing view, I argue that perceptual experiences may well occasionally be states of uncertainty, but that they are never probabilistically structured. I criticize a powerful (...) line of reasoning that we should expect perceptual experience to be probabilistic, given their interfaces with unconscious probabilistic information, with behavior responsive to it, and with credences.

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.

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 volume, a well-known psychoanalyst, dance therapist, and educational consultant chronicles her clinical work with deeply troubled children who fall between the cracks of our diagnostic and educational systems. These children, who frequently turn out to have been sexually or punitively abused, have no real emotional home despite the fact that they live in materially comfortable circumstances. In spite of their apparent brightness and precocity, they do not thrive in the classroom, where their disruptive behavior, tendency to act out, (...) and fragmented learning bring them to the attention of teachers, counselors, and school psychologists. Standard diagnoses do not explain their plight; such children are neither retarded nor learning disabled nor neurotic. Through poignant case studies, Siegel reviews the developmental circumstances that bring these middle-class waifs to a critical impasse with both their parents and the educational establishment. Time and again she discovers that the children's expectable developmental course has been derailed by their accommodation to parental abuse and deformed parental expectations. Psychodynamic treatment invariably uncovers the maladaptive solutions that fueled the children's behavioral and learning disturbances. This volume speaks to a broad clinical and non-clinical readership: psychoanalytic clinicians; psychologists; counselors; social workers; art, dance, and music therapists; special education teachers; child therapists; and child care workers. They will all join in admiration of Siegel's treatment approach which focuses on what is healthy in deeply traumatized children and, in so doing, helps debunk the myth of the untreatable child.

_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)

I argue that inference can tolerate forms of self-ignorance and that these cases of inference undermine canonical models of inference on which inferrers have to appreciate (or purport to appreciate) the support provided by the premises for the conclusion. I propose an alternative model of inference that belongs to a family of rational responses in which the subject cannot pinpoint exactly what she is responding to or why, where this kind of self-ignorance does nothing to undermine the intelligence of the (...) response.

Replies to commentaries on "Can experiences be rational?", forthcoming in Analytic Philosophy.

Siegel defends "Limited Intentionism", a theory of what secures the semantic reference of uses of bare demonstratives ("this", "that" and their plurals). According to Limited Intentionism, demonstrative reference is fixed by perceptually anchored intentions on the part of the speaker.

With what modes of mentality can we build a visceral, subjective sense of being in some specific mass-political society? Theorists and political cultivators standardly call upon the imagination – the kind prompted by symbols and rituals, for example. Could perception ever play such a role? I argue that it can, but that perceptions of mass-political publics come with costs of cruelty and illusion that neither democratic theorists nor participants should be willing to pay. The clearest examples of such perceptions are (...) found in fascist political culture. My discussion aims to illuminate what it is about publics, perception, and democracy that makes this so. -/- .
