In this paper we secure the explanatory value of affordances by treating them as relational properties and as inherently linked to unintentional movements and possible intentional actions. We distinguish between Basic affordances, which are related to unintentional movements, and Complex affordances, which are subjective and executively controlled by individuals. The linkage between affordances and motor intentions allows for accounting for the infinite number of affordances that any given object potentially has. Appealing to objective systematic contingencies that provide the actor with (...) information about the effects of her actions, allows for accounting for perception of affordances and for securing their explanatory value.

Philosophical/epistemic theories of rationality differ over the role of judgment in rational argumentation. According to the “classical model” of rationality, rational justification is a matter of conformity with explicit rules or principles. Critics of the classical model, such as Harold Brown and Trudy Govier, argue that the model is subject to insuperable difficulties. They propose, instead, that rationality be understood, ultimately, in terms of judgment rather than rules. In this article I respond to Brown's and Govier's criticisms of the classical (...) model, and to the “judgment model” they propose in its place. I argue that that model is unable both to distinguish between rational and irrational judgment and to avoid recourse to rules, and is therefore inadequate as an account of rationality, critical thinking, or argument appraisal. More positively, I argue that an adequate account of rationality must include a place for both rules and judgment. (shrink)

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.

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

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)

Reichenbach's well-known distinction between the context of discovery and the context of justification has recently come under attack from several quarters. In this paper I attempt to reconsider the distinction and evaluate various recent criticisms of it. These criticisms fall into two main groups: those which directly challenge Reichenbach's distinction; and those which (I argue) indirectly but no less seriously challenge that distinction by rejecting the related distinction between psychology and epistemology, and defending the "naturalizing" of epistemology. I argue that (...) these recent criticisms fail, and that the distinction remains an important conceptual tool necessary for an adequate understanding of the way in which scientific claims purport to appropriately portray our natural environment.

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.

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.

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)

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.

I am most grateful to the editors of Informal Logic for their willingness to publish my absurdly long paper (Siegel 2023a) in its entirety, and for organizing the four commentaries published along with it. I am grateful as well to Bart Garssen, Andrew Aberdein, Paula Olmos and Christoph Lumer for their insightful and challenging discussions. In what follows I respond to their criticisms and suggestions in the order in which they appear in the journal.

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

Observational learning is ubiquitous. We very often observe and pick up information about how others behave and subsequently replicate similar behaviours in one way or another. Focusing on observational learning, I investigate human imitation, the mechanisms that underpin it as well as the processes that complement it, in order to assess its contribution to learning and education. Furthermore, I construe emotion as a scaffold for observational learning and bring together evidence about its influence on selective attention. Finally, I flesh out (...) possible ways in which the insights about the role of imitation in learning could help design a more effective and equally rewarding learning environment. Specifically, I suggest that perhaps the simplest and most effective way to foster learning via promoting imitation is through letting learners of various ages co-exist. The benefits of learning in a mixed-age group are assessed. (shrink)

Central to argumentation theory is a concern with normativity. Argumentation theorists are concerned, among other things, with explaining why some arguments are good (or at least better than others) in the sense that a given argument provides reasons for embracing its conclusion which are such that a fair- minded appraisal of the argument yields the judgment that the conclusion ought to be accepted -- is worthy of acceptance -- by all who so appraise it.

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)

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.

The traditional views of science as the possessor of a special method, and as the epitome or apex of rationality, have come under severe challenges for a variety of historical, psychological, sociological, political, and philosophical reasons. As a result, many philosophers are either denying science its claim to rationality, or else casting about for a new account of its rationality. In this paper a defense of the traditional view is offered. It is argued that contemporary philosophical discussion regarding the rationality (...) of science is plagued by a failure to distinguish among three different questions, all taken to be "the" question of the rationality of science. Once these questions are delineated, it becomes possible to answer one of them in such a way that the traditional link between science's rationality and its method is reestablished--although the scientific method is itself given a non-traditional rendering. In short, it is argued that there is a feature of science which is appropriately characterized as its method; that this method does in fact secure science's rationality; and that science is therefore correctly construed as preeminently rational. It is suggested in addition that the philosophy of science is itself best seen as a primarily epistemological activity, and consequently that a correction from the excessively historicist conception of recent philosophy of science is in order.

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.

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.

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)

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.

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)

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.

A critique of reflective equilibrium as an account of epistemic justification.

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

In this paper I argue that causal relations between objects are represented in visual experience, and contrast my argument and its conclusion with Michotte's results from the 1960's.

Unlike more standard non-normative naturalizations of epistemology and philosophy of science, Larry Laudan's naturalized philosophy of science explicitly maintains a normative dimension. This paper critically assesses Laudan's normative naturalism. After summarizing Laudan's position, the paper examines (1) Laudan's construal of methodological rules as 'instrumentalities' connecting methodological means and cognitive ends; (2) Laudan's instrumental conception of scientific rationality; (3) Laudan's naturalistic account of the axiology of science; and (4) the extent to which a normative philosophy of science can be naturalized. It (...) is concluded that Laudan's normative naturalism is as problematic as its non-normative naturalist cousins. (shrink)

In this paper I discuss several proposals for how to find out which contents visual experiences have, and I defend the method I.

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.

This paper makes the case that when wishful thinking ill-founds belief, the belief depends on the desire in ways can be recapitulated at the level of perceptual experience. The relevant kinds of desires include motivations, hopes, preferences, and goals. I distinguish between two modes of dependence of belief on desire in wishful thinking: selective or inquiry-related, and responsive or evidence-related. I offers a theory of basing on which beliefs are badly-based on desires, due to patterns of dependence that can found (...) in the relationship between experiences and desires as well. This conclusion brings us a large part of the way to the conclusion that like beliefs, experiences can be ill-founded by depending on a desire. (shrink)
