Over the last four decades arguments for and against the claim that creative hypothesis formation is based on Darwinian ‘blind’ variation have been put forward. This paper offers a new and systematic route through this long-lasting debate. It distinguishes between undirected, random, and unjustified variation, to prevent widespread confusions regarding the meaning of undirected variation. These misunderstandings concern Lamarckism, equiprobability, developmental constraints, and creative hypothesis formation. The paper then introduces and develops the standard critique that creative (...) hypothesis formation is guided rather than blind, integrating developments from contemporary research on creativity. On that basis, I discuss three compatibility arguments that have been used to answer the critique. These arguments do not deny guided variation but insist that an important analogy exists nonetheless. These compatibility arguments all fail, even though they do so for different reasons: trivialisation, conceptual confusion, and lack of evidence respectively. Revisiting the debate in this manner not only allows us to see where exactly a ‘Darwinian’ account of creative hypothesis formation goes wrong, but also to see that the debate is not about factual issues, but about the interpretation of these factual issues in Darwinian terms.

If the sight of cortically blind people were restored, could they visually recognize a cube or a sphere? This is Molyneux’s question. I argue that the answer to this question depends on the specificities of the mental setup of these cortically blind people. Some cortically blind people have (sometimes quite vivid) visual imagery. Others don’t. The answer to Molyneux’s question depends on whether the blind subjects have had visual imagery before their sight was restored. If they (...) did, the answer to Molyneux’s question is yes, if they didn’t, the answer is no. There is no generic answer to Molyneux’s question. (shrink)

An increasing number of scholars at the intersection of feminist philosophy and critical disability studies have turned to Merleau-Ponty to develop phenomenologies of disability or of what, following Rosemarie Garland-Thomson, I call "non-normate" embodiment. These studies buck the historical trend of philosophers employing disability as an example of deficiency or harm, a mere litmus test for normative theories, or an umbrella term for aphenotypical bodily variation. While a Merleau-Pontian-inspired phenomenology is a promising starting point for thinking about embodied experiences (...) of all sorts, I here draw a cautionary tale about how ableist assumptions can easily undermine accounts of non-normate experience. I first argue that the omission or misguided treatment of disability within the history of philosophy in general and the phenomenological tradition in particular is due to the inheritance of what I call “the ableist conflation” of disability with pain, suffering, and disadvantage. I then show that Merleau-Ponty’s famous reading of the blind man’s cane is problematic insofar as it omits the social dimensions of disabled experiences, misconstrues the radicality of blindness as a world-creating disability, and operates via an able-bodied simulation that confuses object annexation or extension with incorporation. In closing, I contend that if phenomenology is to overcome the errors of traditional philosophy, as Merleau-Ponty once hoped, it must heed the insights of “crip” or non-normate phenomenology, which takes the lived experience of disability as its point of departure.

Perceivers generally show a poor ability to detect changes, a condition referred to as “Change Blindness” . They are, in addition, “blind to their own blindness”. A common explanation of this “Change Blindness Blindness” is that it derives from an inadequate, “photographical” folk-theory about perception. This explanation, however, does not account for intra-individual variations of CBB across trials. Our study aims to explore an alternative theory, according to which participants base their self-evaluations on two activity-dependent cues, namely search time (...) and perceived success in prior trials. These cues were found to influence self-evaluation in two orthogonal ways: success-feedback influenced self-evaluation in a global, contextual way, presumably by recalibrating the norm of adequacy for the task. Search time influenced it in a local way, predicting the success of a given trial from its duration. (shrink)

Creativity pervades human life. It is the mark of individuality, the vehicle of self-expression, and the engine of progress in every human endeavor. It also raises a wealth of neglected and yet evocative philosophical questions: What is the role of consciousness in the creative process? How does the audience for a work for art influence its creation? How can creativity emerge through childhood pretending? Do great works of literature give us insight into human nature? Can a computer program really be (...) creative? How do we define creativity in the first place? Is it a virtue? What is the difference between creativity in science and art? Can creativity be taught? The new essays that comprise The Philosophy of Creativity take up these and other key questions and, in doing so, illustrate the value of interdisciplinary exchange. Written by leading philosophers and psychologists involved in studying creativity, the essays integrate philosophical insights with empirical research. CONTENTS I.

This chapter critically analyzes evolutionary epistemology as a theoretical framework for the study of science as a historical and cultural phenomenon. As spelled out by Campbell in the 1970s, evolutionary epistemology has an ambitious goal: it aims at understanding the complex relations between bio- logical evolution, especially the biological evolution of human cognition, and the cultural evolution of scientific knowledge. It eventually aims at forming an integrated causal theory of the evolution of science, starting with the evo- lution of human (...) cognition. In this chapter, the author considers Campbell’s project and specifies why it is still today a worthwhile project for explain- ing the evolution of science as a specific case of cultural evolution. But he also criticizes Campbell’s evolutionary epistemology for assuming that blind variation and selective retention are the processes through which science evolves. This assumption, the author argues, is at odds with much of what we know about scientific cognition and the history of science. He advocates (1) dropping the methodological constraint of looking for processes of blind variation and selective retention at the expense of other constructive processes and mechanisms of knowledge production; but (2) retaining the integrative point of evolutionary epistemology, which implies taking seriously the results of evolutionary psychology; and (3) retaining the populational framework for explaining the history of science, which means questioning why some scientific beliefs and practices eventually spread and stabilize in a scientific community. We end up with an updated research program for evolutionary epistemology, which faces new challenges. (shrink)

Understanding, for Kant, does not intuit, and intuition—which involves empirical information, i.e., sense-data—does not entail thinking. What is crucial to Kant’s famous claim that intuitions without concepts are blind and concepts without intuitions are empty is the idea that we have no knowledge unless we combine concepts with intuition. Although concepts and intuition are radically separated mental powers, without a way of bringing them together (i.e., synthesis) there is no knowledge for Kant. Thus Kant’s metaphysical-scientific dualism: (scientific) knowledge is (...) limited to the world of phenomena—the world of appearance—while the thing-in-itself is unknowable because there is no intuition that can correspond to the it. This paper sets to cull Béatrice Longuenesse’s recent work on the first-person ‘I’ and put forth a novel Kantian approach to the first-person reference of mental states, working in the tradition of P.F. Strawson, Rudolf Carnap, and Wilfrid Sellars, while offering an empirical study of deafferentation to ground the thesis that the binding of representations is separate from phenomenal consciousness. Accordingly, we stake a kind of self-consciousness vis-à-vis the Fundamental Reference-Rule qua apperception that, while intimately connected to consciousness of one’s own body, apperception is nevertheless distinct from it and is, moreover, the condition for any use of ‘I’. We compliment neuroscientist Oliver Sacks’ research with Ned Block’s recent work on “no-post‐perceptual cognition” and attentional variation to couch Kant’s schema in perceptual psychology. We navigate Kant’s work on intuitions (viz. sensation, perception, and the empirical side of the cognitive faculties) and indirect realism/weak representationism first via Sellars’ naturalization of Kant’s inaccessible thing-in-itself, before challenging Sellars’ functionalist and inferentialist conception of perception and discursive intentionality. We ultimately endeavor to conceptualize the limit-conditions regarding our having reportable knowledge about our access to percepts and concepts. (shrink)

Many of the poems of Louis MacNeice display a knowledge of the philosophical theories he studied during his undergraduate years in Oxford. In his ‘Variation on Heraclitus’ and in several other poems, MacNeice alludes to the ‘doctrine of flux’ Plato attributed to the Greek thinker Heraclitus of Ephesus. In ‘Plurality’, his most extended exploration of the conflict between the life-affirming doctrine of flux and a life-suppressing monism, MacNeice embraces the reality of change and rejects the monism he credits to (...) the philosopher Parmenides of Elea: ‘World is not like that, world is full of blind/ Gulfs across the flat, jags against the mind/ Swollen or diminished according to the dice/ Foaming, never finished, never the same twice.’ Although his understanding of the teachings of Heraclitus and Parmenides was controversial, it provided MacNeice with a framework within which to reflect on the conditions essential to living a free and productive life.

Large changes that occur in clear view of an observer can become difficult to notice if made during an eye movement, blink, or other such disturbance. This change blindness is consistent with the proposal that focused visual attention is necessary to see change, with a change becoming difficult to notice whenever conditions prevent attention from being automatically drawn to it. -/- It is shown here how the phenomenon of change blindness can provide new results on the nature of visual attention, (...) including estimates of its capacity and the extent to which it can bind visual properties into coherent descriptions. It is also shown how the resultant characterization of attention can in turn provide new insights into the role that it plays in the perception of scenes and events. (shrink)

In evolutionary biology, niche construction is sometimes described as a genuine evolutionary process whereby organisms, through their activities and regulatory mechanisms, modify their environment such as to steer their own evolutionary trajectory, and that of other species. There is ongoing debate, however, on the extent to which niche construction ought to be considered a bona fide evolutionary force, on a par with natural selection. Recent formulations of the variational free-energy principle as applied to the life sciences describe the properties of (...) living systems, and their selection in evolution, in terms of variational inference. We argue that niche construction can be described using a variational approach. We propose new arguments to support the niche construction perspective, and to extend the variational approach to niche construction to current perspectives in various scientific fields. (shrink)

This paper discusses the so-called non-interference assumption (NIA) grounding causal inference in trials in both medicine and the social sciences. It states that for each participant in the experiment, the value of the potential outcome depends only upon whether she or he gets the treatment. Drawing on methodological discussion in clinical trials and laboratory experiments in economics, I defend the necessity of partial forms of blinding as a warrant of the NIA, to control the participants’ expectations and their strategic interactions (...) with the experimenter.

Change blindness is the striking failure to see large changes that normally would be noticed easily. Over the past decade this phenomenon has greatly contributed to our understanding of attention, perception, and even consciousness. The surprising extent of change blindness explains its broad appeal, but its counterintuitive nature has also engendered confusions about the kinds of inferences that legitimately follow from it. Here we discuss the legitimate and the erroneous inferences that have been drawn, and offer a set of requirements (...) to help separate them. In doing so, we clarify the genuine contributions of change blindness research to our understanding of visual perception and awareness, and provide a glimpse of some ways in which change blindness might shape future research. (shrink)

Perhaps the most striking phenomenon of visual awareness is inattentional blindness (IB), in which a surprisingly salient event right in front of you may go completely unseen when unattended. Does IB reflect a failure of perception, or only of subsequent memory? Previous work has been unable to answer this question, due to a seemingly intractable dilemma: ruling out memory requires immediate perceptual reports, but soliciting such reports fuels an expectation that eliminates IB. Here we introduce a way of evoking repeated (...) IB in the same subjects and the same session: we show that observers fail to report seeing salient events’ not only when they have no expectation, but also when they have the wrong expectations about the events nature. This occurs when observers must immediately report seeing anything unexpected, even mid-event. Repeated IB thus demonstrates that IB is aptly named: it reflects a genuine deficit in moment-by-moment conscious perception, rather than a form of inattentional amnesia. (shrink)

Normativists about belief hold that belief formation is essentially rule- or norm-guided. On this view, certain norms are constitutive of or essential to belief in such a way that no mental state not guided by those norms counts as a belief, properly construed. In recent influential work, Kathrin Glüer and Åsa Wikforss develop novel arguments against normativism. According to their regress of motivations argument, not all belief formation can be rule- or norm-guided, on pain of a vicious infinite regress. I (...) argue that the regress of motivations argument is unsuccessful: an appeal to the notion of blind rule-following, drawn from a plausible interpretation of Ludwig Wittgenstein’s remarks on rule-following, stops the regress of motivations in its tracks.

I use an old challenge to motivate a new view. The old challenge is due to variation in our perceptions of secondary qualities. The challenge is to say whose perceptions are accurate. The new view is about how we manage to perceive secondary qualities, and thus manage to perceive them accurately or inaccurately. I call it perceptual structuralism. I first introduce the challenge and point out drawbacks with traditional responses. I spend the rest of the paper motivating and defending (...) a structuralist response. While I focus on color, both the challenge and the view generalize to the other secondary qualities. (shrink)

Animal ethicists have recently debated the ethical questions raised by disenhancing animals to improve their welfare. Here, we focus on the particular case of breeding hens for commercial egg-laying systems to become blind, in order to benefit their welfare. Many people find breeding blind hens intuitively repellent, yet ‘welfare-only’ positions appear to be committed to endorsing this possibility if it produces welfare gains. We call this the ‘Blind Hens’ Challenge’. In this paper, we argue that there are (...) both empirical and theoretical reasons why even those adopting ‘welfare-only’ views should be concerned about breeding blind hens. But we also argue that alternative views, which (for example) claim that it is important to respect the telos or rights of an animal, do not offer a more convincing solution to questions raised by the possibility of disenhancing animals for their own benefit.

The basis of perception is the processing and categorization of perceptual stimuli from the environment. Much progress has been made in the science of perceptual categorization. Yet there is still no consensus on how the brain generates sensory individuals, from sensory input and perceptual categories in memory. This chapter argues that perceptual categorization is highly variable across perceivers due to their use of different perceptual strategies for solving perceptual problems they encounter, and that the perceptual system structurally adjusts to the (...) strategies that are most successful. Despite this variability, the different sensory individuals that result when different perceivers rely on different strategies nonetheless correspond to actual external world objects/features. This view is called 'perceptual pluralism'. (shrink)

High percentages of submitted papers are rejected at editorial levels without offering a second chance to authors by sending their papers for further peer-reviews. In most cases, the rejections are typical quick answers without helpful argumentations related to the content of the rejected material. More surprisingly, some journals vaunt their high rejection rates as a “mark of prestige”!However, journals that reject high percentages of submitted papers have built their prominent positions based on a flawed measure, the impact factor, and from (...) a long and favorable historical context. Their shareholders may think that they are allowed to have a large margin of rejection rates without affecting their sponsorship or funding sources thanks to an extended anchorage since tens, or in some cases hundreds, of years compared to unknown or new journals that struggle to pave a way in the scientific publication world. Historical anchorage of some journals also makes it unfair to compare old and new .. (shrink)

In this paper, I argue that the ‘social meanings’ associated with sociolinguistic variation put pressure on the standard philosophical conception of language, according to which the foremost thing we do with words is exchange information. Drawing on parallels with the explanatory challenge posed by slurs and pejoratives, I argue that the best way to understand social meanings is to think of them in speech act theoretic terms. I develop a distinctive form of pluralism about the performances realized by means (...) of sociolinguistic variants, and I claim that engagement with such performances is an utterly pervasive feature of our linguistic activity.

In the not-too-distant past, vision was often said to involve three levels of processing: a low level concerned with descriptions of the geometric and photometric properties of the image, a high level concerned with abstract knowledge of the physical and semantic properties of the world, and a middle level concerned with anything not handled by the other two. The negative definition of mid-level vision contained in this description reflected a rather large gap in our understanding of visual processing: How could (...) the here-and-now descriptions of the low levels combine with the enduring knowledge of the high levels to produce our perception of the surrounding world? A number of experimental and theoretical efforts have been made over the past few decades to solve this "mid-level crisis". One of the more recent of these is based on the phenomenon of change blindness—the difficulty in seeing a large change in a scene when the transients accompanying that change no longer convey information about its location (Rensink, O'Regan, & Clark, 1997; Rensink, 2000a). Phenomenologically, this effect is quite striking: the change typically is not seen for several seconds, after which it suddenly snaps into awareness. During the time the change remains "invisible", there is an apparent disconnection of the low-level descriptions (which respond to the change) from subjective visual experience (which does not). As such, this effect would seem to have the potential to help us understand how mid-level mechanisms might knit low- and high-level processes into a coherent representation of our surroundings. -/- It is argued here that this potential can indeed be realized, and that change blindness can teach us much about the nature of mid-level vision.3 A number of studies are first reviewed showing that the perception of a scene does not involve a steady buildup of detailed representation: rather, it is a dynamic process, with focused attention playing one of the main roles, viz., forming coherent object representations whenever needed. It is then argued that change blindness can also shed considerable light on the nature of focused attention itself, such as its speed, capacity, selectivity, and ability to bind together visual properties into coherent structures.

The philosopher Ludwig Wittgenstein cites the Gestalt psychologist Wolfgang Koehler almost as often as he cites William James in his posthumously published writings on the philosophy of psychology. Yet, few treatments of the Wittgenstein–Koehler relation in the philosophical literature could be called sustained discussions. Moreover, most of them treat Koehler as a mere whipping boy for Wittgenstein, one more opportunity to criticize the practice of psychologists. This article emphasizes how much the two thinkers agreed, and the extent to which some (...) of Wittgenstein’s work not only agreed with but also has a logical structure parallel to some of Koehler’s text. Both thinkers hold that the theoretician should strive to recognize and resist the impulse to step in and purify, distill, streamline, or exclude phenomena: common, everyday experience for Koehler and common, everyday uses of words for Wittgenstein. They both aim to counteract the tendency to discount and disparage what is ordinary and common. (shrink)

According to Smell Objectivism, the smells we perceive in olfactory experience are objective and independent of perceivers, their experiences, and their perceptual systems. Variations in how things smell to different perceivers or in different contexts raise a challenge to this view. In this paper, I offer an objectivist account of non-illusory contextual variation: cases where the same thing smells different in different contexts of perception and there is no good reason to appeal to misperception. My central example is that (...) of dihydromyrcenol, a substance that can smell both woody and citrusy depending on what other odourants one has recently been exposed to. I first argue that the subjects’ apparently conflicting reports about the way dihydromyrcenol smells are best understood as comparative characterisations of a smell. Given this understanding, different reports can be correctly made in response to perceiving the very same smell. I then argue that the phenomenal difference between the experiences subjects have across contexts can be explained compatibly with Smell Objectivism. On the account proposed, subjects perceive the very same smell but different qualities, notes, or aspects of it are salient to them, depending on the context of perception. I then consider how the proposed defence of Smell Objectivism can be adapted to other cases where the same thing is reported as smelling different in different contexts. (shrink)

Parapsychology will only be accepted as part of mainstream science if physics can be extended to accommodate at least some so-called psychic phenomena. This paper disagrees with the argument of Reber and Alcock that these phenomena can be excluded a priori because they are incompatible with physics. On the other hand, it agrees with their claim that the phenomena cannot be explained in terms of current physics (eg. relativity theory and quantum theory). Rather one needs an extension of physics which (...) amalgamates these theories, this being an aim of mainstream physics anyway, with the new theory also linking to consciousness if this is regarded as a fundamental rather than incidental feature of the universe. One possible extension involves the idea that perceptual space and physical space are amalgamated as part of a 5-dimensional reality structure, the extra dimension being associated with mental (rather than physical) time. Such a model may be required to accommodate even normal mind and incorporating further dimensions might then allow some paranormal phenomena. This could also relate to the extra dimensions invoked in some models of particle physics. (shrink)

As observers, we generally have a strong impression of seeing everything in front of us at any moment. But compelling as it is, this impression is false – there are severe limits to what we can consciously experience in everyday life. Much of the evidence for this claim has come from two phenomena: change blindness (CB) and inattentional blindness (IB). -/- CB refers to the failure of an observer to visually experience changes that are easily seen once noticed. This can (...) happen even if the changes are large, constantly repeat, and the observer has been informed that they will occur. A related phenomenon is IB – the failure to visually experience an object or event when attention is directed elsewhere. For example, observers may fail to notice an unexpected object that enters their visual field, even if this object is large, appears for several seconds, and has important consequences for the selection of action. -/- Both phenomena involve a striking failure to report an object or event that is easily seen once noticed. As such, both are highly counterintuitive, not only in the subjective sense that observers have difficulty believing they could fail so badly at seeing but also in the objective sense that these findings challenge many existing ideas about how we see. But as counterintuitive as these phenomena are, progress has been made in understanding them. Indeed, doing so has allowed us to better understand the limitations of human perception in everyday life and to gain new insights into how our visual systems create the picture of the world that we experience each moment our eyes are open.

The topic of this paper is the complex interaction between attention, fixation, and one species of change blindness. The two main interpretations of the target phenomenon are the ‘blindness’ interpretation and the ‘inaccessibility’ interpretation. These correspond to the sparse view (Dennett 1991; Tye, 2007) and the rich view (Dretske 2007; Block, 2007a, 2007b) of visual consciousness respectively. Here I focus on the debate between Fred Dretske and Michael Tye. Section 1 describes the target phenomenon and the dialectics it entails. Section (...) 2 explains how attention and fixation weigh in these debates, and argues that Dretske’s hyper-rich view fails precisely because he overlooks certain effects of attention and fixation. Section 3 explains why Tye’s view is also unsatisfying, mainly because he misconceives the degree of access. Section 4 then puts forward the positive model covariance, which has it that the degree of cognitive access tracks the degree of phenomenology, and contrasts it with Block’s view on the Sperling iconic memory paradigm. The paper ends with a discussion of levels of seeing, which involve crowding, indexing, and other visual phenomena. Change ‘blindness’ is a set of phenomena that was discovered about two decades ago, yet an entirely satisfying understanding is still lacking. To move forward, a more detailed understanding of attention and fixation is called for. (shrink)

In this work, we will approach some essential questions about the collective imaginary and their relations with reality and truth. We should face this subject in a conceptual framework, followed by the corresponding factual analysis of demonstrable behavioral realities. We will adopt not only the methodology, but mostly the tenets and propositions of the analytic philosophy, which certainly will be apparent throughout the study, and may be identified by the features described by Perez : -/- Rabossi (1975) defends the idea (...) that analytic philosophy can be identified by considering certain family resemblances. He suggests the following family traits: a positive attitude toward scientific knowledge; a cautious attitude toward metaphysics; a conception of philosophy as a conceptual task, which takes conceptual analysis as a method; a close relationship between language and philosophy; a concern with seeking argumentative answers to philosophical problems; search for conceptual clarity Perez, Diana Ines, "Analytic Philosophy in Latin America”, The Stanford Encyclopedia of Philosophy ). These core concepts involve cultural, social, religious, scientific, philosophic, moral, and political contents, belonging to the individual and collective existence of each one of us. The present work grounds itself on analytical reflection. We will speculate the most comprehensive and profound way we can and express the results of our thoughts. Notwithstanding the multidisciplinary nature of the subject and the methodological openness for accepting contributions from any field of science, this work belongs to the aim of psychology and ontology or, in other terms, social and ontological psychology. The main scope of this paper is to observe how some essential evolutionary attributes of humankind, like creativity, imagination, and association, can become a hazardous sickness, sheltered in the misty shadows of the intelligence.

Individuals tend to judge bad side effects as more intentional than good side effects (the Knobe or side- effect effect). Here, we assessed how widespread these findings are by testing eleven adult cohorts of eight highly contrasted cultures on their attributions of intentional action as well as ratings of blame and praise. We found limited generalizability of the original side-effect effect, and even a reversal of the effect in two rural, traditional cultures (Samoa and Vanuatu) where participants were more likely (...) to judge the good side effect as intentional. Three follow-up experiments indicate that this reversal of the side-effect effect is not due to semantics and may be linked to the perception of the status of the protagonist. These results highlight the importance of factoring cultural context in our understanding of moral cognition. (shrink)

Our recent opinion article [1] examined what change blindness can and cannot tell us about visual representations. Among other things, we argued that change blindness can tell us a lot about how visual representations can be used, but little about their extent. We and others found the ‘sparse representations’ view appealing (and still do), and initially made the overly strong claim that change blindness supports the conclusion of sparse representations [2,3]. We wrote our article because change blindness continues to be (...) taken as evidence for sparse – or even absent – representations, and we used O’Regan and Noë’s influential paper [4] as an example. However, as has been noted for some time [5–8], this conclusion is logically flawed: lack of ability need not be caused by lack of representation. (shrink)

The ambiguity theory of ‘knows’ is the view that ‘knows’ and its cognates have more than one propositional sense – i.e. more than one sense that can properly be used in ‘knows that’ etc. constructions. Given that most of us are ‘intuitive invariantists’ – i.e. most of us initially have the intuition that ‘knows’ is univocal – defenders of the ambiguity theory need to offer an explanation for the semantic blindness present if ‘knows’ is in fact ambiguous. This paper is (...) an attempt to offer such an explanation. Section 1 contains a general argument for the ubiquity of semantic blindness for ambiguous words; the upshot being that semantic blindness for the ambiguity of ‘knows’ is thus unsurprising. Section 2 offers more specific arguments for why ‘knows’ is the type of ambiguous word that we’re very unlikely to quickly recognize is ambiguous. (shrink)

Today we find philosophical naturalists and Christian theists both expressing an interest in virtue epistemology, while starting out from vastly different assumptions. What can be done to increase fruitful dialogue among these divergent groups of virtue-theoretic thinkers? The primary aim of this paper is to uncover more substantial common ground for dialogue by wielding a double-edged critique of certain assumptions shared by `scientific' and `theistic' externalisms, assumptions that undermine proper attention to epistemic agency and responsibility. I employ a responsibilist virtue (...) epistemology to this end, utilizing it most extensively in critique of Alvin Plantinga’s Warranted Christian Belief (2000). Epistemological externalism presages, I also argue, a new demarcation problem, but a secondary aim of the paper is to suggest reasons to think that `responsibilist externalism,' especially as glossed in virtue-theoretic terms, provides its proponents with the ability to adequately address this problem as we find it represented in a potent thought-experiment developed by Barry Stroud.

There is variation in how people perceive colors and other secondary qualities. The challenge of perceptual variation is to say whose perceptions are accurate. According to Sextus, Protagoras’ response is that all of our perceptions might be accurate. As this response is traditionally developed, it is difficult to explain color illusion and color constancy. This difficulty is due to a widespread assumption called perceptual atomism. This chapter argues that, if we want to develop Protagoras’ response, we need to (...) give up perceptual atomism. It ends with a brief sketch of an alternative called perceptual structuralism. (shrink)

Though Socrates can easily look like a cosmopolitan in moral and political theory, a closer reading of the relevant texts shows that, in the most important sense of the term as we now use it, he turns out – disappointingly, perhaps – not to be. The reasons why not are instructive and important, both for readers of Plato and for political theorists; they have to do with the phenomenon that I shall call ethical blind-spots.

According to the traditional Bayesian view of credence, its structure is that of precise probability, its objects are descriptive propositions about the empirical world, and its dynamics are given by conditionalization. Each of the three essays that make up this thesis deals with a different variation on this traditional picture. The first variation replaces precise probability with sets of probabilities. The resulting imprecise Bayesianism is sometimes motivated on the grounds that our beliefs should not be more precise than (...) the evidence calls for. One known problem for this evidentially motivated imprecise view is that in certain cases, our imprecise credence in a particular proposition will remain the same no matter how much evidence we receive. In the first essay I argue that the problem is much more general than has been appreciated so far, and that it’s difficult to avoid without compromising the initial evidentialist motivation. The second variation replaces descriptive claims with moral claims as the objects of credence. I consider three standard arguments for probabilism with respect to descriptive uncertainty—representation theorem arguments, Dutch book arguments, and accuracy arguments—in order to examine whether such arguments can also be used to establish probabilism with respect to moral uncertainty. In the second essay, I argue that by and large they can, with some caveats. First, I don’t examine whether these arguments can be given sound non-cognitivist readings, and any conclusions therefore only hold conditional on cognitivism. Second, decision-theoretic representation theorems are found to be less convincing in the moral case, because there they implausibly commit us to thinking that intertheoretic comparisons of value are always possible. Third and finally, certain considerations may lead one to think that imprecise probabilism provides a more plausible model of moral epistemology. The third variation considers whether, in addition to conditionalization, agents may also change their minds by becoming aware of propositions they had not previously entertained, and therefore not previously assigned any probability. More specifically, I argue that if we wish to make room for reflective equilibrium in a probabilistic moral epistemology, we must allow for awareness growth. In the third essay, I sketch the outline of such a Bayesian account of reflective equilibrium. Given that this account gives a central place to awareness growth, and that the rationality constraints on belief change by awareness growth are much weaker than those on belief change by conditionalization, it follows that the rationality constraints on the credences of agents who are seeking reflective equilibrium are correspondingly weaker.

While we may not be able simply to choose what we believe, there is still scope for culpability for what we come to belief. I explore here the distinction between culpable and non-culpable theistic unbelief, investigating the process of self-deception to which we can voluntarily contribute in cases where we do become culpable for failing to believe something.

Semantic blindness is the inability to recognize semantic features of terms one can competently use. A theory that implies semantic blindness incurs a burden to explain how one can competently use a term without realizing how the term works. An argument advanced in favor of epistemic relativism is that its main competitors, contextualism and subject-sensitive invariantism, imply that speakers suffer from semantic blindness regarding ‘knows’ while relativism has no such implication. However, there is evidence that relativism also implies semantic blindness (...) regarding ‘knows,’ apparently crippling the case for relativism. In this paper I argue that the semantic blindness that affects relativism is not a problem at all. First, the blindness is not as widespread as it appears. It does not prevent ordinary speakers from expressing important epistemic truths. Further, I provide an error theory for relativism that has three features that render it unproblematic: there is evidence independent of relativism that people make this error, relativism predicts this error; it is not an ad hoc rescue, the error only occurs in rare and obscure situations. People are fallible and finite, and assuming relativism is true, they make mistakes exactly where we should expect them to. (shrink)

The ‘man born blind restored to light’ was one of the foundational myths of the Enlightenment, according to Foucault. With ophthalmic surgery in its infancy, the fascination by the sighted with blindness and what the blind might ‘see’ after sight restoration remained largely speculative. Was being blind, as Descartes once remarked, like ‘seeing with the hands’? Did evidence from early cataract operations begin to resolve epistemological debates about the relationship between vision and touch in the newly sighted, (...) such as the famous ‘Molyneux Question’ posed by William Molyneux to John Locke? More recently, how have autobiographical accounts of blind and vision impaired writers and poets advanced the sighted public’s understanding of blind subjectivity? -/- Through an unfolding historical, philosophical and literary narrative that includes Locke, Molyneux and Berkeley in Britain, and Diderot, Voltaire and Buffon in France, this book explores how the Molyneux Question and its aftermath has influenced attitudes towards blindness by the sighted, and sensory substitution technologies for the blind and vision impaired, to this day.

The Elephant and the Blind is a book about why we need a new culture of consciousness, and how to get it. A culture of consciousness (or Bewusstseinskultur) is a culture that values and cultivates the mental states of its members in an ethical and evidence-based way.

Three errors of "The Blind Watchmaker" theory are examined with Aristotelian thought.

Darwin's ideas on variation, heredity, and development differ significantly from twentieth-century views. First, Darwin held that environmental changes, acting either on the reproductive organs or the body, were necessary to generate variation. Second, heredity was a developmental, not a transmissional, process; variation was a change in the developmental process of change. An analysis of Darwin's elaboration and modification of these two positions from his early notebooks (1836-1844) to the last edition of the /Variation of Animals and (...) Plants Under Domestication/ (1875) complements previous Darwin scholarship on these issues. Included in this analysis is a description of the way Darwin employed the distinction between transmission and development, as well as the conceptual relationship he saw between heredity and variation. This paper is part of a larger project comparing commitments regarding variation during the latter half of the nineteenth century. (shrink)

The term psychopathy refers to a personality disorder associated with callous personality traits and antisocial behaviors. Throughout its research history, psychopathy has frequently been described as a peculiar form of moral blindness, engendering a narrative about a patient stereotype incapable of taking a genuine moral perspective, similar to a blind person who is deprived of proper visual perceptions. However, recent empirical research has shown that clinically diagnosed psychopaths are morally more fit than initially thought, and the blindness-analogy now comes (...) across as largely misleading. In this contribution, the moral-blindness analogy is explored in an attempt to qualify anew its relevance in psychopathy theory and research. It is demonstrated that there are indeed theoretically relevant parallels to be drawn between blindness and psychopathy, parallels that are especially illuminating when accounting for the potential symptomatology, dimensionality, and etiological nature of the disorder.

This paper is about the alethic aspect of epistemic rationality. The most common approaches to this aspect are either normative (what a reasoner ought to/may believe?) or evaluative (how rational is a reasoner?), where the evaluative approaches are usually comparative (one reasoner is assessed compared to another). These approaches often present problems with blindspots. For example, ought a reasoner to believe a currently true blindspot? Is she permitted to? Consequently, these approaches often fail in describing a situation of alethic maximality, (...) where a reasoner fulfills all the alethic norms and could be used as a standard of rationality (as they are, in fact, used in some of these approaches). I propose a function α, which accepts a set of beliefs as inputand returns a numeric alethic value. Then I use this function to define a notion of alethic maximality that is satisfiable by finite reasoners (reasoners with cognitive limitations) and does not present problems with blindspots. Function α may also be used in alethic norms and evaluation methods (comparative and non-comparative) that may be applied to finite reasoners and do not present problems with blindspots. A result of this investigation isthat the project of providing purely alethic norms is defective. The use of function α also sheds light on important epistemological issues, such as the lottery and the preface paradoxes, and the principles of clutter avoidance and reflection. (shrink)

A long-standing debate in group ontology and group epistemology concerns whether some groups possess mental states and/or epistemic states such as knowledge that do not reduce to the mental states and/or epistemic states of the individuals who comprise such groups (and are also states not possessed by any of the members). Call those who think there are such states inflationists. There has recently been a defense in the literature of a specific type of inflationary knowledge—viz., knowledge of facts about group (...) minds or group self-knowledge (GS-K). In this paper I address whether some groups do possess such knowledge. I argue that we have good reason to think they do not. I do so by exploring the most explicit defense of such knowledge in the literature—Lukas Schwengerer’s (2022) defense—as well as other ways of defending this thesis and arguing that such ways are problematic. In the latter part of the paper, I explain why the two most popular inflationary approaches to group knowledge simpliciter are incompatible with there being GS-K. In doing so I work to show why even inflationists should reject the view that there is inflationary group self-knowledge. (shrink)

This book surveys the ways in which languages of different types refer to past, present, and future events and how these referents are related to the knowledge and attitudes of discourse participants. The book is the culmination of fifteen years of research by the author. Four major language types are examined in-depth: tense-based English, tense-aspect-based Polish, aspect-based Chinese, and mood-based Kalaallisut. Each contributes to a series of logical representation languages, which together define a common logical language that is argued to (...) underlie all language types. The four types differ in whether they choose to grammaticalize discourse reference to times (tense), events (aspect), and/or attitudes (mood), and how non-grammaticalized elements are inferred. The common logical language is a dynamic update logic, building on DRT and Centering Theory, but with a novel architecture—e.g. the distinction between focal vs. peripheral attention plays a key role, parallel to focal vs. peripheral vision.

This paper is about teaching elementary logic to blind or visually impaired students. The targeted audience are teachers who all of sudden have a blind or visually impaired student in their introduction to logic class, find limited help from disability centers in their institution, and have no idea what to do. We provide simple techniques that allow direct communication between a teacher and a visually impaired student. We show how the use of what is known as Polish notation (...) simplifies communication, and pedagogically is a great notation for a Braille reader. (shrink)

Frege famously claimed that variations in the sense of a proper name can sometimes be ‘tolerated’. In this paper, we offer a novel explanation of this puzzling claim. Frege, we argue, follows Trendelenburg in holding that we think in language—sometimes individually and sometimes together. Variations in sense can be tolerated in just those cases where we are using language to coordinate our actions but are not engaged in thinking together about an issue.

Together, the code and inferential models of communication are often thought to range over all cases of communication. However, their prevailing versions seem unable to fully explain what I call underdeterminacy without ostension. The latter is constituted by communication where stimuli that are not (nor appear to be) produced with communicative or informative intentions nevertheless communicate information underdetermined by the relevant codes. Though the prevailing accounts of communication cannot fully explain how communication works in such cases, I suggest that some (...) version of the inferential model can—if we allow it to extend to non‐ostensive, non‐intentional behaviors.

The purpose of this paper is to contribute to the ongoing analyses that aim to confront the problem of marked variation. Negatively marked differences are those natural variations that are used to cleave human beings into different categories (e.g., of disablement, of medicalized pathology, of subnormalcy, or of deviance). The problem of marked variation is: Why are some rather than other variations marked as epistemically or culturally significant or as a diagnostic of pathology, and What is the epistemic (...) background that makes these—rather than other variations—marked as subnormal? For Wilson (2018a), critical examination of the problem of marked variation is central to understanding the epistemology of medicalized pathology that made the history of eugenics possible. My aim is to explore the role marked variation plays in eugenic and other problematic classifications and the inferences they appear to license. I pay particular attention to the normative valuations of marked variations, how these valuations affect the inferences that are made by others about those possessing the variation, and how those possessing the variation perceive themselves. In the final sections, I illustrate this by critically discussing three putative kinship conceptions of race. I rely on these to extend the scope of the puzzle of marked variation from the context of historic and current markings of an individual’s variation as disability in the eugenics movement to historic and current markings for assigning putative racial ascriptions to individuals and groups. Lastly, I suggest that the problem of marked variation is a problem that looms over any epistemic account that is dependent upon sorting or classifying. (shrink)
