Intuitive judgments elicited by verbal case-descriptions play key roles in philosophical problem-setting and argument. Experimental philosophy's ‘sources project’ seeks to develop psychological explanations of philosophically relevant intuitions which help us assess our warrant for accepting them. This article develops a psycholinguistic explanation of intuitions prompted by philosophical case-descriptions. For proof of concept, we target intuitions underlying a classic paradox about perception, trace them to stereotype-driven inferences automatically executed in verb comprehension, and employ a forced-choice plausibility-ranking task to elicit the relevant (...) stereotypical associations of perception- and appearance-verbs. We obtain a debunking explanation that resolves the philosophical paradox. (shrink)

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

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.

Primarily, this article emphasises that while conducting research, especially one involving human subjects, researchers are expected to comply with applicable global and national ethical standards. Should a researcher fail to do so, he/she stands the risk of breaching research ethics, and this is capable of rendering his/her research unacceptable. Accordingly, this article, making reference to relevant ethical theories, critically examines and analyses the actions of a researcher who set out to investigate treatment recommendations for diarrhoea. Ultimately, a number of ethical (...) pitfalls in the stated research are x-rayed and some recommendations for subsequent studies are provided in this paper. (shrink)

This addendum presents results that confound some commonly made claims about the sorts of environments in which the performance of TTB exceeds that of Franklin's rule, and vice versa.

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.

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

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)

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.

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.

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)

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.

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

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.

chapter on perception and bias including implicit bias.

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)

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.

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. -/- .

Blending the qualitative and analytic research methods, this article critically examines the nature and limitations of inductive arguments within the field of logic. Inductive arguments, unlike their deductive counterparts, provide conclusions that extend beyond the premises, thus offering probabilistic rather than certain conclusions. This critique emphasises the weak inferential connections inherent in inductive reasoning, where premises give only partial or probable support to conclusions. The analysis highlights the ampliative value of inductive arguments, illustrating how they broaden conceptual knowledge by introducing (...) new information. However, the article also delves into reasons for their limited acceptance in logic, focusing on their probabilistic nature, contingency, experiential basis, and susceptibility to fallacies such as hasty generalisation, composition, false cause, and appeal to authority. Despite these criticisms, the article recognises that inductive arguments hold significant merit in scientific inquiry and everyday reasoning, contrasting with the firm, analytic nature of deductive arguments used in formal logic and philosophical analysis. The article concludes by advocating for a balanced approach in argumentation, underscoring the need to appreciate the contextual strengths and limitations of both inductive and deductive reasoning in the pursuit of effective logical analysis.

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)

So much value is ascribed to human life. This is so because life is generally regarded as a precious gift to humanity, which should be cherished and protected, as failure to cherish and protect life will bring about the inevitable extinction of the entire human race. Abortion is one of the numerous contemporary issues that undermine the sanctity and value of human life; for it involves terminating a pregnancy by removing a fetus or embryo before it can survive independent of (...) the uterus, or killing the fetus inside the uterus. The issue of abortion is highly controversial; for while some individuals permit it, some others condemn it totally, as evident in the 'pro-life' versus 'pro-choice' controversy. 'Pro-life' advocates condemn abortion because it is an outright disrespect for the dignity and value of human life, and hold that there should be sustained discussions on it, to expose its danger and fatal consequences. 'Pro-choice' advocates are simply indifferent to the issue of abortion; for them, getting involved in abortion is a matter of choice for an individual - that is, one is at liberty to accept or reject abortion so that in the final analysis, abortion should not be an issue for discussion. This article explores several arguments and bioethical concerns on abortion, approaches to the issue of abortion, and Nigeria's abortion provisions, which are evident in the Criminal and Penal Codes, respectively. Ultimately, this article recommends that beyond merely stating punishments for those involved in abortion, the following should be done: (a) Correcting the disparity between the Criminal and Penal Codes by ensuring that both Codes have the same penalty stated, or completely reducing them into a single Code that will be applied across the country, (b) Modifying the Criminal and Penal Codes by including information that will serve the purpose of educating Nigerians on the bioethical issues associated with abortion, and (c) Designating a body charged with ensuring compliance with and implementation of the abortion laws.

My contribution to the first round of a tetralog with Bill Brewer, Anil Gupta, and John McDowell.

The world today is marked by linguistic diversity. It has nonetheless been described as a global village. Consequently, there is a growing interest in understanding issues across cultures and languages. This has necessitated the translation of texts and thoughts into languages that can reach out to a greater number of people. The challenge, however, has been to retain the originally intended meaning in the new language into which a text is translated. The concern of this paper is to elucidate the (...) concept of translation and the views of philosophers on the concept, with a view to understanding the problem of translation, especially as it relates to African Philosophy. Ultimately, this research establishes that the problem of translating African philosophical thought can be addressed through (a) improved capacity building of African translators, (b) better access to resources and increased collaboration between African and non-African scholars, and (c) use of a “third language” as a medium of communication, which can help bridge cultural and linguistic gaps between African and non-African philosophical thoughts.

This study examines the epistemological implications of the adoption of Artificial Intelligence (AI) in researches within the information age. Focusing on the particular case of Margaret Lawrence University, a leading research institution situated in Galilee, Ika North-East Local Government Area of Delta State, Nigeria, this study assesses the implications of AI-aided research and questions the integrity of AI-generated knowledge. Precisely, this study discusses the epistemological status of AI-generated knowledge by weighing the prospects and shortcomings of using AI in research. Also, (...) this study explores a number of ethical considerations associated with AI-aided research, such as potential bias, digital piracy, and the risk of misinterpretation of results. Collectively, the Findings of this study reveal that although AI has great potentials for advancing research, it has far-reaching implications for the integrity of research. This study concludes by recommending a number of measures which can be employed to foster responsible use of AI in research and ultimately ensure research integrity in Margaret Lawrence University and elsewhere.

Entry in Routledge handbook of skill and expertise. Discusses social perception, perceptual expertise, knowing what things look like, and a bit about about aesthetics at the end.

Are human beings actually free beings? The doctrine of determinism gives a negative response to this question. Determinism therefore claims that humans are not free to act or make choices, since they are always constrained in some way. By so doing, determinism denies human freedom and human moral responsibility. It rejects the idea that humans act freely, or that humans can be regarded as responsible for their actions and inactions. This outright denial of human freedom and human moral responsibility is (...) certainly pregnant with several implications, which this article is aimed at exposing. This article adopts the expository, analytic and critical methods. It begins with a clarification of the concept of determinism and then goes on to discuss five types of determinism, namely: (a) physical, (b) psychological, (c) historical, (d) ethical and (e) theological determinism, respectively. Also, this article discusses two categories of determinism known as soft and hard determinism. Furthermore, this article exposes some implications of determinism for events and humanity. Finally, adopting eclecticism as its theoretical framework, this article proposes that it is best to approach the doctrine of determinism by simply recognising and accepting the fact that there are aspects of humans that are determined, and there are equally aspects of humans that are not determined. By so doing, this article establishes that approaching the doctrine of determinism eclectically is the surest way of accommodating the opposing doctrines of determinism and 'freewillism.’. (shrink)

This paper offers a thorough appraisal of Peter David Klein's epistemological infinitism, emphasising his treatment of scepticism and the issue of infinite regress in epistemic justification. Klein, a prominent figure in contemporary epistemology, advocates for infinitism; a theory that argues justification is an unending process where each belief requires further reasons indefinitely. The study critically evaluates how Klein's defense of infinitism provides a distinctive response to the infinite regress problem, a core concern in scepticism. By contextualising Klein's theory within the (...) broader framework of epistemology, the research explores its implications for ongoing debates on justification and scepticism. The methodology includes a thematic analysis of Klein's key philosophical contributions, coupled with a critical examination of competing justification theories such as foundationalism, coherentism, and contextualism. Employing a comparative approach, the study assesses Klein's infinitism alongside these rival theories by drawing on primary texts and relevant secondary literature. The paper is divided into five sections: an introduction to scepticism and epistemic justification, an analysis of Klein's infinite regress argument, an exploration of traditional solutions to the regress problem, criticisms of infinitism, and an appraisal of Klein's contributions. The findings reveal that, despite its innovative approach, Klein's infinitism encounters significant theoretical and practical challenges. The conclusion assesses whether infinitism can adequately address the regress problem and considers its relevance to real-world epistemic practices. (shrink)

The problem of language in African philosophy is coextensive with the question as to whether there exists an African philosophy. This is so because when the question: "what language is African philosophy to be done?" arises, it implicitly calls into question the very foundation of the discipline. Little wonder then, that the language question has remained a front-burner issue in African philosophy. Essentially, the problem of Language in African philosophy raises the question as to whether the expression of the African (...) experience of reality in foreign languages can generate an authentically African philosophy. Put differently, the problem centers on whether or not foreign languages should be used to express African philosophical thoughts. In an attempt to address this problem, two camps have surfaced among African philosophers, namely, the conservatives and the progressives. For the conservatives, for a philosophy to be authentically African, it must be expressed in African languages. They base their argument on the fact that language is tied to culture and every culture has its peculiar conceptual framework. Consequently, to express the African experience of reality in a foreign language necessarily implicates 'conceptual superimposition.' In contrast, the progressives commit themselves to a more pragmatic approach to the question of language. They opine that the lack of a continental lingua franca in Africa legitimizes the use of foreign languages. This research therefore evaluates the position of both camps with a view to establishing the possibility and plausibility of having an authentic African philosophy in foreign languages. This is without prejudice to the significance of African languages in construing the African experience of reality. This research employs the expository, analytic, and evaluative methods. (shrink)

This dissertation is a critical examination of Kant's use of the notion of "moral progress" throughout all of his writings. The dissertation is divided into two sections. The first looks at Kant's analysis of history and teleology. I argue, against many commentators, that Kant is already aware of the limitations of the concept of teleology with the writing of the first Critique, and thus his important notion of moral progress does not go beyond the bounds set by the first Critique, (...) nor is it merely a misconstrued notion of teleology which is eliminated with the third Critique. ;In the first section I make three main points. First, I argue that Kant gives us two locations for the highest good: in an afterlife and on earth. I argue that we ought to take this division and its implications seriously. Second, I argue that Kant uses the notion of moral progress as a postulate of pure practical reason, necessary for the defense of a highest good on earth. Third, I show that there is a strong connection between moral progress and politics, arguing that political institutions are a necessary but not sufficient condition for moral progress. ;The second section is constructive, attempting to show exactly how this notion of moral progress operates in Kant's philosophy. In the first half, I present an intensive analysis of Kant's concept of the highest good, several problems with its conceivability, and its link between morality and politics. Next, I outline what I take to be the five steps involved in moral progress. In the last chapters I argue that the notion of moral progress is indeed a necessary postulate of practical reason given the rest of Kant's philosophical system. I conclude by showing how my interpretation strengthens Kant's position and gives new insight to his understanding of political theory. (shrink)

This paper defends an analysis of the epistemic contours of the interface between individuals and their cultural milieu.

Discourse shapes the way we see the world. In game design and game studies, discourse also shapes the games we make, the games we play, and how we think about games in general. One key discursive construction in contemporary game culture is to portray some games as ‘real’ or ‘authentic,’ rendering others as fake or lesser. In this essay we analyze the discourse of real games by focusing on four key discursive constructions that prop up notions of real games: developer (...) pedigree, game mechanics, the celebration of depth and complexity, and the payment structure for games. Using the framework of constitutive rhetoric we argue that these appeals also construct a category of real gamers that has a substantial impact on what games are available and how we think about them.

Vigilantism, commonly glossed as “taking the law into one’s own hands,” has been analyzed differently in studies of comparative politics, ethnography, history, and legal theory, but has attracted little attention from philosophers. What can “taking the law into one’s hands” amount to? How does vigilantism relate to mobs, protests, and self-defense? I distinguish between several categories of vigilantism, identify the questions they are most useful for addressing, and offer an analysis on which vigilantism is a kind of political initiative done (...) for the sake of enacting an immediate realignment of power in a polity in accordance with a political vision. In addition to defining a special kind of political initiative, my analysis helps us understand a range of rhetorical powers related to vigilantism, including some of the ways that attributions of vigilantism can mask instances of self-defense, and attributions of self-defense can mask instances of vigilantism.

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)
