This book argues that misinformation poses a multi-faceted threat to knowledge, while arguing that some forms of content moderation risk exacerbating these threats. It proposes alternative forms of content moderation that aim to address this complexity while enhancing human epistemic agency. The proliferation of fake news, false conspiracy theories, and other forms of misinformation on the internet and especially social media is widely recognized as a threat to individual knowledge and, consequently, to collective deliberation and democracy itself. This (...) book argues that misinformation presents a three-pronged threat to knowledge. While researchers often focus on the role of misinformation in causing false beliefs, this deceptive potential of misinformation exists alongside the potential to suppress trust and to distort the perception of evidence. Recognizing the multi-faceted nature of this threat is essential to the development of effective measures to mitigate the harms associated with misinformation. The book weaves together work in analytic epistemology with emerging empirical work in other disciplines to offer novel insights into the threats posed by misinformation. Additionally, it breaks new ground by systematically assessing different forms of content moderation from the perspective of epistemology. Misinformation, Content Moderation, and Epistemology will appeal to philosophers working in applied and social epistemology, as well as scholars and advanced students in disciplines such as communication studies, political science, and social psychology who are researching misinformation.

This paper will be concerned with the role acquaintance plays in contemporary theories of introspection. Traditionally, the relation of acquaintance has been conceived in analytic epistemology and philosophy of mind as being only epistemically relevant inasmuch as it causes, or enables, or justifies a peculiar kind of propositional knowledge, i.e., knowledge by acquaintance. However, in recent years a novel account of the role of acquaintance in our introspective knowledge has been offered. According to this novel constitutive approach, (...) acquaintance is, in itself, a sui generis—i.e., non-propositional—kind of knowledge. As we will suggest, a stalemate between David Chalmers’ account of direct phenomenal concepts—as a prototypical example of a causal view—and Anna Giustina’s account of primitive introspection—as a prototypical example of a constitutive view—is looming in the current controversy between the two families of theories. Towards the end of the essay, we will point to some possible ways for a constitutive theorist to break the stalemate. (shrink)

The paper explicates a new way to model the context-sensitivity of 'knows', namely a way that suggests a close connection between the content of 'knows' in a context C and what is pragmatically presupposed in C. After explicating my new approach in the first half of the paper and arguing that it is explanatorily superior to standard accounts of epistemic contextualism, the paper points, in its second half, to some interesting new features of the emerging account, such as its compatibility (...) with the intuitions of Moorean dogmatists. Finally, the paper shows that the account defended is not subject to the most prominent and familiar philosophical objections to epistemic contextualism discussed in the recent literature. (shrink)

Reductionists about knowledge-wh hold that "s knows-wh" (e.g. "John knows who stole his car") is reducible to "there is a proposition p such that s knows that p, and p answers the indirect question of the wh-clause." Anti-reductionists hold that "s knows-wh" is reducible to "s knows that p, as the true answer to the indirect question of the wh-clause." I argue that both of these positions are defective. I then offer a new analysis of knowledge-wh as a (...) special kind of de re knowledge. (shrink)

ABSTRACT This essay defends a qualified version of Quine's thesis of universal revisability against Chalmers's recent conditionalization-based criticisms of it. It is argued that an embodied view of cognitive processing undermines Chalmers's account of nonrevisable a priori justification, which presupposes that concepts prefigure the confirmation-relations into which they enter, so as to make such relations rationally accessible to anyone who possesses those concepts. On the view developed here, bodily interaction with the world and the accompanying subconscious processing can change subjects' (...) dispositions to apply their concepts, in ways that are not rationally accessible to them, even given a complete description of that interaction, and do not constitute a change in the content of the concepts involved. Thus a subject who treats a proposition as indefeasibly justified a priori might nevertheless significantly lower her credence in that proposition, in ways that are not accessible to the subject on the basis of her grasp of the content of the relevant concepts. This discussion has further implications concerning the role of the a priori in the philosophical enterprise. (shrink)

Can novels, plays and poetry tell us something important and true about who we are, about others, and about life generally? The question seems to be of interest not only to writers on literary theory and aesthetics, but to people generally. This paper considers the issues involved.

Expert testimony figures in recent debates over how best to understand the norm of assertion and the domain-specific epistemic expectations placed on testifiers. Cases of experts asserting with only isolated second-hand knowledge (Lackey 2011, 2013) have been used to shed light on whether knowledge is sufficient for epistemically permissible assertion. I argue that relying on such cases of expert testimony introduces several problems concerning how we understand expert knowledge, and the sharing of such knowledge through testimony. (...) Refinements are needed to clarify exactly what principles are being tested by such cases; but once refined, such cases raise more questions than they answer. (shrink)

This paper argues that both a limited doxastic voluntarism and anti-evidentialism are consistent with the views that the aim of belief is truth or knowledge and that this aim plays an important role in norm-setting for beliefs. More cautiously, it argues that limited doxastic voluntarism is (or would be) a useful capacity for agents concerned with truth tracking to possess, and that having it would confer some straightforward benefits of both an epistemic and non-epistemic variety to an agent concerned (...) with truth tracking.

According to social externalism, it is possible to possess a concept not solely in virtue of one’s intrinsic properties but also in virtue of relations to one’s linguistic community. Derek Ball (2009) argues, in effect, that (i) social externalism extends to our concepts of colour experience and (ii) this fact undermines both the knowledge argument against physicalism and the most popular physicalist response to it, known as the phenomenal concept strategy. I argue that Ball is mistaken about (ii) even (...) granting (i). The knowledge argument and the phenomenal concept strategy might have to be modified to make them consistent with social externalism, but not in fundamental or detrimental ways. (shrink)

My goal in this paper is to show that Kant’s prohibition on certain kinds of knowledge of things-in-themselves is motivated less by his anti-soporific encounter with Hume than by his new view of the distinction between “real” and “logical” modality, a view that developed out of his reflection on the rationalist tradition in which he was trained. In brief: at some point in the 1770’s, Kant came to hold that a necessary condition on knowing a proposition is that one (...) be able to prove that all the items it refers to are either really possible or really impossible. Most propositions about things-in-themselves, in turns out, cannot meet this condition. I conclude by suggesting that the best interpretation of this modal condition is as a kind of coherentist constraint. (shrink)

For millennia, knowledge has eluded a precise definition. The industrialization of knowledge (IoK) and the associated proliferation of the so-called knowledge communities in the last few decades caused this state of affairs to deteriorate, namely by creating a trio composed of data, knowledge, and information (DIK) that is not unlike the aporia of the trinity in philosophy. This calls for a general theory of knowledge (ToK) that can work as a foundation for a science of (...) knowledge (SoK) and additionally distinguishes knowledge from both data and information. In this paper, I attempt to sketch this generality via the establishing of both knowledge structures and knowledge systems that can then be adopted/adapted by the diverse communities for the respective knowledge technologies and practices. This is achieved by means of a formal–indeed, mathematical–approach to epistemological matters a.k.a. formal epistemology. The corresponding application focus is on knowledge systems implementable as computer programs. (shrink)

A crucial part of the contemporary interest in logicism in the philosophy of mathematics resides in its idea that arithmetical knowledge may be based on logical knowledge. Here an implementation of this idea is considered that holds that knowledge of arithmetical principles may be based on two things: (i) knowledge of logical principles and (ii) knowledge that the arithmetical principles are representable in the logical principles. The notions of representation considered here are related to theory-based (...) and structure-based notions of representation from contemporary mathematical logic. It is argued that the theory-based versions of such logicism are either too liberal (the plethora problem) or are committed to intuitively incorrect closure conditions (the consistency problem). Structure-based versions must on the other hand respond to a charge of begging the question (the circularity problem) or explain how one may have a knowledge of structure in advance of a knowledge of axioms (the signature problem). This discussion is significant because it gives us a better idea of what a notion of representation must look like if it is to aid in realizing some of the traditional epistemic aims of logicism in the philosophy of mathematics.

What is the relation between joint attention and common knowledge? On the one hand, the relation seems tight: the easiest and most reliable way of knowing something in common with another is for you and that other to be attentively aware of what you are together experiencing. On the other hand, they couldn’t seem further apart: joint attention is a mere perceptual phenomena that infants are capable of engaging in from nine months of age, whereas common knowledge is (...) a cognitive phenomenon involving (so it seems) complex, overlapping metarepresentational states that require the kind of sophisticated mindreading skills that developmental psychology has shown to be beyond the capabilities of young children. In 'The Shared World: Perceptual Common Knowledge, Demonstrative Communication, and Shared Social Space', Axel Seemann attempts, inter alia, to makensense of this conundrum. (shrink)

Much work in MKM depends on the application of formal logic to mathematics. However, much mathematical knowledge is informal. Luckily, formal logic only represents one tradition in logic, specifically the modeling of inference in terms of logical form. Many inferences cannot be captured in this manner. The study of such inferences is still within the domain of logic, and is sometimes called informal logic. This paper explores some of the benefits informal logic may have for the management of informal (...) mathematical knowledge. (shrink)

Epistemic contextualism is widely believed to be incompatible with the recently popular view that knowledge is the norm of assertion, practical reasoning, or belief. I argue in this article that the problems arising for contextualism from the mentioned normative views are only apparent and can be resolved by acknowledging the fairly widespread phenomenon of non-obvious context-sensitivity (recently embraced by even some of contextualism's most ardent former critics). Building on recent insights about non-obvious context-sensitivity, the article outlines an independently attractive (...) contextualist account of the mentioned epistemic norms and provides a solution to the puzzles they give rise to in a contextualist framework.

Few recent developments in information technology have been as hyped as blockchain, the first implementation of which was the cryptocurrency Bitcoin. Such hype furnishes ample reason to be skeptical about the promise of blockchain implementations, but I contend that there’s something to the hype. In particular, I think that certain blockchain implementations, in the right material, social, and political conditions, constitute excellent bases for common knowledge. As a case study, I focus on trust in election outcomes, where the ledger (...) records not financial transactions but vote tallies. I argue that blockchain implementations could foster warranted trust in vote tallies and thereby trust in the democratic process. Finally, I argue that if the promise of blockchain implementations as democratic infrastructure is to be realized, then democracies first need to ensure that these material, social, and political conditions obtain.

Abstract Timothy Williamson has recently proposed to undermine modal skepticism by appealing to the reducibility of modal to counterfactual logic ( Reducibility ). Central to Williamson’s strategy is the claim that use of the same non-deductive mode of inference ( counterfactual development , or CD ) whereby we typically arrive at knowledge of counterfactuals suffices for arriving at knowledge of metaphysical necessity via Reducibility. Granting Reducibility, I ask whether the use of CD plays any essential role in a (...) Reducibility-based reply to two kinds of modal skepticism. I argue that its use is entirely dispensable, and that Reducibility makes available replies to modal skeptics which show certain propositions to be metaphysically necessary by deductive arguments from premises the modal skeptic accepts can be known.

This book examines a main theme in religious epistemology, namely, the possibility of knowledge of God. Most often philosophers consider the rationality or justification of propositional belief about God, particularly beliefs about the existence and nature of God; and they will assess the conditions under which, if there is a God, such propositional beliefs would be knowledge, particularly in light of counter-evidence or the availability of religious disagreement. This book surveys such familiar areas, then turns toward newer and (...) less-developed terrain: interpersonal epistemology, namely what it is to know another person. It then explores the prospects for understanding what it might take to know God relationally, the contours of which are significant for many theistic traditions. (shrink)

Ideomotor actions are behaviours that are unconsciously initiated and express a thought rather than a response to a sensory stimulus. The question examined here is whether ideomotor actions can also express nonconscious knowledge. We investigated this via the use of implicit long-term semantic memory, which is not available to conscious recall. We compared accuracy of answers to yes/no questions using both volitional report and ideomotor response . Results show that when participants believed they knew the answer, responses in the (...) two modalities were similar. But when they believed they were guessing, accuracy was at chance for volitional report , but significantly higher for Ouija response . These results indicate that implicit semantic memory can be expressed through ideomotor actions. They also suggest that this approach can provide an interesting new methodology for studying implicit processes in cognition. (shrink)

Cumulative cultural knowledge [CCK], the knowledge we acquire via social learning and has been refined by previous generations, is of central importance to our species’ flourishing. Considering its importance, we should expect that our best epistemological theories can account for how this happens. Perhaps surprisingly, CCK and how we acquire it via cultural learning has only received little attention from social epistemologists. Here, I focus on how we should epistemically evaluate how agents acquire CCK. After sampling some reasons (...) why extant theories cannot account for CCK, I suggest that things aren’t as bleak as they might look. I explain how agents deserve epistemic credit for how CCK is transmitted in cultural learning by promoting a central need of their social group: The efficient and safe transmission of CCK. A good initial fit exists between this observation and Greco’s knowledge-economy framework. Ultimately, however, Greco’s account doesn’t straightforwardly account for CCK because of its strict focus on testimony. I point out two issues in the framework due to this focus. The resulting view advocates giving epistemic credit to agents when they act to promote their communities’ epistemic needs in the right way and highlights the various ways in which agents come to do this.

This chapter examines three characteristics of environmental sciences—prediction, replication and the use of models—to explore their dissonance with the traditional representation of science. While ‘Science’ is often idealised as objective, universal, and context-independent, environmental sciences operate in ways that do not fit into these assumptions. The chapter draws on Bruno Latour’s distinction between ‘Science’ and ‘sciences’ to argue that environmental sciences, with their inherent uncertainties, local contexts, and interdisciplinary methods, conflict with the image of science as a monolithic and universally (...) reliable source of knowledge. Referring to case studies, the text explores how environmental sciences craft complex, interconnected systems that defy the reproducibility and predictability often associated with ‘Science’. This dissonance, maintains, has led to issues such as climate denialism and the politicisation of scientific knowledge. From this perspective, a call is made for a revaluation of how environmental sciences are represented in both public and policy arenas, calling for a more nuanced understanding of their provisional, context-specific nature and for educational reforms that help the public better grasp the complexities of scientific knowledge production.

A discussion of Sosa's Knowing Full Well. The authors focus on the understood place and significance of animal and reflective knowledge.

Although Spinoza’s words about intuition, also called “the third kind of knowledge,” remain among the most difficult to grasp, I argue that he succeeds in providing an account of its distinctive character. Moreover, the special place that intuition holds in Spinoza’s philosophy is grounded not in its epistemological distinctiveness, but in its ethical promise. I will not go as far as one commentator to claim that the epistemological distinction is negligible (Malinowski-Charles 2003),but I do argue that its privileged place (...) in Spinoza’s system belongs primarily to its ethical importance, by which I mean that intuition’s value is prized by virtue of the agency it confers upon those who enjoy it. Spinoza often notes that what distinguishes the “wise man” is that he is more powerful, able to do more. That is,the wise and free person with whose description the Ethics culminates is set apart not, first and foremost, by virtue of possessing a scientific account of the true cosmological order. The Ethics is perhaps called an ethics, rather than a treatise on metaphysics or knowledge, because it concludes with a demonstration of how one comes to be able to do what is best and to live a more joyful life. Intuitive science is essential to the characterization of the power to think and live well. (shrink)

This chapter explores insights concerning the relations among imagination, imagined selves, and knowledge of one’s own self that are to be found in Fernando Pessoa’s The Book of Disquiet. The insights are explored via close reading of the text and comparison with contemporaries of Pessoa. First, a tempting account of the importance of imagination in The Book of Disquiet is set out. On this reading, Pessoa is immersed in miasmatic boredom, but able to temporarily rise above it through the (...) restorative powers of escapist imagination. But, it is suggested, Pessoa neither enjoys his prolific imaginings, nor returns from them restored. It is argued that Pessoa’s disquiet owes to failures of imagination; the book presents a sharp contrast between Pessoa’s keen awareness of the importance of a successful, active imaginative life, and his failure to maintain such a thing. It is further argued that these failures point us towards a better account of imagination’s importance to Pessoa, an account that both prefigures and goes beyond Sartre’s ideas about the relations between nothingness, imagination, and self-consciousness.

An impressive case has been built for the hypothesis that knowledge is the norm of assertion, otherwise known as the knowledge account of assertion. According to the knowledge account, you should assert something only if you know that it’s true. A wealth of observational data supports the knowledge account, and some recent empirical results lend further, indirect support. But the knowledge account has not yet been tested directly. This paper fills that gap by reporting the (...) results of such a test. The knowledge account passes with flying colors. (shrink)

Open peer commentary on the article “Ethics: A Radical-constructivist Approach” by Andreas Quale. Upshot: The first of my two main goals in this commentary is to establish thinking of ethics as concepts rather than as non-cognitive knowledge. The second is to argue that establishing models of individuals’ ethical concepts is a scientific enterprise that is quite similar to establishing models of individuals’ mathematical concepts. To accomplish these two primary goals, I draw from my experience of working scientifically with von (...) Glasersfeld for 25 years while he was developing radical constructivism as a coherent model of knowing, and appeal to several of his basic insights to establish constructing models of ethical concepts as a scientific enterprise.

The article aims at formulating a philosophical framework and by this giving some means at hand to save human libertarian freedom, God’s omniscience and God’s ”eternity’. This threefold aim is achieved by 1) conceiving of an agent as having different possibilities to act, 2) regarding God’s knowledge -- with respect to agents -- not only as being ”propositional’ in character but also as being ”experiential’: God knows an agent also from the ”first person perspective’, as the agent knows herself, (...) and, 3), formulating ”eternity’ and ”temporality’ as being homeomorphically related to each other. This gives rise to a coherent interplay that saves both human libertarian freedom and God’s omniscient ”view from eternity’. (shrink)

Williams Syndrome provides a striking test case for discourses on disability, because the characteristics associated with Williams Syndrome involve a combination of “abilities” and “disabilities”. For example, Williams Syndrome is associated with disabilities in mathematics and spatial cognition. However, Williams Syndrome individuals also tend to have a unique strength in their expressive language skills, and are socially outgoing and unselfconscious when meeting new people. Children with Williams are said to be typically unafraid of strangers and show a greater interest in (...) contact with adults than with their peers. This apparently keen social knowledge is a counterexample to the discussion of disability among academic philosophers, especially philosophers of the early modern period. Locke infamously used the example of disability to claim that Descartes’ arguments in favor of innate ideas were incorrect. On the contrary, Williams Syndrome may stand as an example of innate social knowledge; something that could benefit current discourse in philosophy, disability theory, and medical ethics. (shrink)

Let us call a thought or belief whose content would be expressed by a sentence of subject-predicate form (by the thinker or someone attributing the thought to the thinker) an ‘ascription’. Thus, the thought that Madonna is middle-aged is an ascription of the property of being middle-aged to Madonna. To call a thought of this form an ascription is to emphasize the predicate in the sentence that gives its content. Let us call an ‘x-ascription’ an ascription whose subject is x, (...) that is, an ascription such that the subject of the sentence which would express its content is x. Let us call a ‘self-ascription’ an ascription whose subject is identical with the ascriber. Let us call a ‘reflexive ascription’ a selfascription such that either (i) in the sentence the ascriber would use to attribute correctly the ascription to himself he would use the first person pronoun to refer to himself both as the ascriber and as the subject of the ascription, as in a sentence of the form, I believe that I ö.

This short enquiry investigates the relationships between knowledge of English and attitude towards the English language as held by Japanese university students. The goal of this study was to gain a better understanding of how attitude affects the learning of English and whether gender or geographic location of a student ’s hometown plays a role. A random sample of 85 participants completed a 26 item questionnaire which measured background information, attitude to English and knowledge of English. The difference (...) in English knowledge over several prefectures was tested using ANOVA and the results indicated that there was no statistical difference observed. Difference in attitude to English between male and female students was tested using a t-test and no statistical difference was observed. Pearson Correlation was used to test for any relationship between knowledge and attitude to English, but again no statistical different relationship was found. In addition , Multiple Regression was used to determine if there was a linear relationship between knowledge of English, and the 3 variables attitude to English, gender and prefecture. Again there was no statistically significant linear relationship between these variable. (shrink)

In this paper, we present a dialectical argument for a priori skepticism (i.e. the thesis that we can be skeptical about a priori knowledge). Then, we propose a framework that combines elements from inferential contextualism and logical conventionalism to offer a weak transcendental argument against a priori skepticism.

ABSTRACT. Thought experiments about de se attitudes and Jackson’s original Knowledge Argument are compared with each other and discussed from the perspective of a computational theory of mind. It is argued that internal knowledge, i.e. knowledge formed on the basis of signals that encode aspects of their own processing rather than being intentionally directed towards external objects, suffices for explaining the seminal puzzles without resorting to acquaintance or phenomenal character as primitive notions. Since computationalism is ontologically neutral, (...) the account also explains why neither Lewis’s two gods nor Mary’s surprise in the Knowledge Argument violate physicalism. (shrink)

In this article I want to alert investigators who are familiar only with our neuropsychological investigations of self-knowledge to our earlier work on model construction.

In this essay I take up Plato’s critique of poetry, which has little to do with epistemology and representational imitation, but rather the powerful effects that poeticperformances can have on audiences, enthralling them with vivid image-worlds and blocking the powers of critical reflection. By focusing on the perceived psychological dangers of poetry in performance and reception, I want to suggest that Plato’s critique was caught up in the larger story of momentous shifts in the Greek world, turning on the rise (...) of literacy and its far-reaching effects in modifying the original and persisting oral character of Greek culture. The story of Plato’s Republic in certain ways suggests something essential for comprehending the development of philosophy in Greece (and in any culture, I would add): that philosophy, as we understand it, would not have been possible apart from the skills and mental transformations stemming from education in reading and writing; and that primary features of oral language and practice were a significant barrier to the development of philosophical rationality (and also a worthy competitor for cultural status and authority). Accordingly, I go on to argue that the critique of writing in the Phaedrus is neither a defense or orality per se, nor a dismissal of writing, but rather a defense of a literate soul over against orality and the indiscriminate exposure of written texts to unworthy readers.

Scholars have long noted that, for Leibniz, the attributes or Ideas of God are the ultimate objects of human knowledge. In this paper, I go beyond these discussions to analyze Leibniz’s views about the nature and limitations of such knowledge. As with so many other aspects of his thought, Leibniz’s position on this issue—what I will call his divine epistemology—is both radical and conservative. It is also not what we might expect, given other tenets of his system. For (...) Leibniz, “God is the easiest and the hardest being to know.” God is the easiest to know, in that to grasp some property of an essence is to attain a knowledge of the divine essence, but God is also the most difficult to know, in that “real knowledge” of the divine essence is not available to finite beings. There is an enormous gap between the easy and the real knowledge of God, but for Leibniz, this gap is a good thing, since the very slowness of our epistemological journey prepares us morally for its end.

In his "On the Metaphysics of Knowledge" (this volume), Sven Bernecker introduces and defends a novel account of knowledge that he calls ‘identificationism’. In fact, Bernecker’s account is a hybrid view that combines a modal tracking condition – some variation on safety and/or sensitivity – with his original identificationist condition. The reason for including a tracking condition is that some Gettier cases, like the famous fake barn case, are best accommodated in this way. In making this more familiar (...) claim, Bernecker follows epistemologists like Nozick, Sosa, or Pritchard. But he also adds the less familiar claim that there are ‘intractable’ Gettier cases that cannot be dealt with by a tracking condition alone. These intractable cases involve necessary or modally stable propositions, such as '2+2=4' or 'there is carbon on earth', which are either true in all possible worlds, or at least true in all possible worlds that are close to the actual world. In this paper, I will not directly address the epistemological adequacy of Bernecker’s identificationism. Rather, I want to focus on the substantial metaphysical commitments that it incurs, in particular on the problematic idea that our epistemic reasons identify the truthmaker of our respective belief when we know something. My conclusion will be that being a truthmaker for p is metaphysically more demanding than being an epistemic reason for p. A truthmaker for p must necessitate the truth of p, while an epistemic reason for p must merely indicate the truth of p. Thus, we should not expect that epistemic reasons identify the truthmakers of our knowledge-constituting beliefs in the way that Bernecker suggests. (shrink)

Mainstream analytic epistemology regards knowledge as the property of individuals, rather ‎than groups. Drawing on insights from the reality of knowledge production and dissemination ‎in the sciences, I argue, from within the analytic framework, that this view is wrong. I defend ‎the thesis of ‘knowledge-level justification communalism’, which states that at least some ‎knowledge, typically knowledge obtained from expert testimony, is the property of a ‎community and possibly none of its individual members, in that only (...) the community or some ‎members of it collectively possesses knowledge-level justification for its individual members’ ‎beliefs. I address several objections that individuals, qua individuals, have or are able to ‎acquire knowledge-level justification for all the beliefs they obtain from expert testimony. I ‎argue that the problem I identify with individualism is invariant under any specific account of ‎justification, internalist or externalist. ‎. (shrink)

The question of how we can be certain that we have an epistemic justification for our self-knowledge has been among a central debate in philosophy of mind. The basic idea of the immunity to error through misidentification thesis (IEM) in explaining self-knowledge is that certain self-ascriptions of mental states concerning first-person content are not prone to error for the self-conscious ‘I’-thoughts. One of the accounts that supports that claim is agentialism. According to this view, we can have beliefs (...) and intentions about ourselves because we exercise agency over them. However, irrational factors such as emotional interference, inconsistent subject affiliation, and different views on the mind leading to different self-references can call this claim to the subject’s rational agency into question. This paper examines the agentialism, identifies its flaws, and presents two alternative strategies to support a rationalist account of self-knowledge—which is generally weaker than agentialism. It argues that the agential approach to self-knowledge is too demanding on the subject’s consciousness thus a more moderate approach is required to satisfy both first-person authority and the epistemic reliability of self-knowledge.

What do you know when you know what a sentence means? According to some theories, understanding a sentence is, in part, knowing its truth-conditions. Dorit Bar-On, Claire Horisk, and William Lycan have defended such theories on the grounds of an “epistemic determination argument”. That argument turns on the ideas that understanding a sentence, along with knowledge of the non-linguistic facts, suffices to know its truth-value, and that being able to determine a sentence’s truth-value given knowledge of the non-linguistic (...) facts is knowing its truth-conditions. I argue that the EDA withstands the objections recently raised by Daniel Cohnitz and Jaan Kangilaski, but fails for other reasons. It equivocates between a fine-grained and a coarse grained conception of “facts.”. (shrink)

According to rationalists about moral knowledge, some moral truths are knowable a priori. Rationalists often defend their position by claiming that some moral propositions are self-evidently true. Copp 2007 has recently challenged this rationalist strategy. Copp argues that even if some moral propositions are self-evident, this is not enough to secure rationalism about moral knowledge, since it turns out that such self-evident propositions are only knowable a posteriori. This paper considers the merits of Copp’s challenge. After clarifying the (...) rationalists’ appeal to self-evidence, I show why this rationalist strategy survives Copp’s challenges to it. (shrink)

Part of a book symposium on Ernest Sosa's Knowing Full Well. An important feature of Sosa's epistemology is his distinction between animal knowledge and reflective knowledge.

"Twilight of the Idols" plays an important role in Nietzsche’s work, since it represents the opening writing of the philosophical project called "Transvaluation of all values". In that text, Nietzsche aims to sound out the "eternal idols", which means to disclose the inconsistency of the principles of traditional metaphysics. The way Nietzsche addresses the "old truths" in Twilight of the Idols leads back to his early writings, when his theory of knowledge is first outlined, inspired by Schopenhauer as much (...) as neo- and post-Kantian thinkers such as F. Lange and A. Spir. As I shall show, these observations can be compared with Ernst Mach's anti-metaphisical attitude to the ordinary world-conception, insofar as Mach as much as Nietzsche stressed the importance of a historical approach as instrument to enlighten the "prejudices" of traditional scientists or philosophers.

I argue for the usefulness of the distinction between knowledge that is, and knowledge that is not, acquired in such a way as necessarily to be acquired along with other knowledge so acquired. Knowledge gained in the latter ways—e.g. by testimony, by linguistic stipulation—has proved philosophically puzzling. But this is because philosophers have used traditional epistemological vocabulary to try to describe what’s distinctive about it. Using the solitary/embedded distinction, we can frame descriptions that are both true, (...) and not stipulative-seeming, of what is distinctive of knowledge gained in these ways. I illustrate these points by discussing Saul Kripke’s claim that one can gain non-linguistic knowledge by linguistic stipulation. (shrink)

William Oliver Martin published "The Order and Integration of Knowledge" in 1957 to address the problem of the nature and the order of various kinds of knowledge; in particular, the theoretical problem of how one kind of knowledge is related to another kind. Martin characterizes kinds of knowledge as being either autonomous or synthetic. The latter are reducible to two or more of the autonomous (or irreducible) kinds of knowledge, viz., history (H), metaphysics (Meta), theology (...) (T), formal logic (FL), mathematics (Math), and generalizations of experimental science (G). Metaphysics and theology constitute the two domains of the ontological context while history and experimental science are the two domains of the phenomenological context. The relation of one kind of knowledge to another may be instrumental, constitutive, and/or regulative. For instance, historical propositions are constitutive of G, metaphysical propositions are regulative of G, and propositions in formal logic and mathematics are instrumental to G. Theological propositions are not related to G and so there is no conflict between science and theology. Martin's work sheds light on the possible areas of incompatibility between science and religion. (shrink)

The Relationship Between Language, Mathematics, Information, Knowledge, and New Discoveries in Understanding the Nature of Consciousness -/- Introduction -/- The nature of consciousness has long been a subject of philosophical and scientific inquiry.

These intellectual advancements not only reflect consciousness but also influence its development. By examining the interplay between language, mathematics, information, knowledge, and new (...) discoveries, we can gain deeper insight into how consciousness emerges, evolves, and expands. -/- Language: The Foundation of Conscious Thought -/- Language is the primary medium through which consciousness expresses itself. It allows individuals to articulate thoughts, share experiences, and construct complex ideas. Without language, higher-order thinking and self-reflection would be severely limited. -/- 1. Language and Self-Awareness – Internal dialogue, or the “voice in our head,” is a critical component of consciousness. It enables introspection, planning, and the ability to reflect on past experiences. -/- 2. Language and Social Consciousness – Through shared language, individuals contribute to collective intelligence. Cultural knowledge, traditions, and ideologies are preserved and transmitted across generations. -/- 3. Language and Abstract Thinking – Words enable humans to discuss non-physical concepts such as justice, morality, and the nature of existence, expanding the boundaries of conscious thought. -/- As language evolves, so does consciousness, leading to new ways of perceiving and interpreting reality. -/- Mathematics: The Language of Patterns and Conscious Awareness -/- Mathematics is often described as a universal language that reveals the underlying order of the universe. It provides structure to human cognition and enhances our ability to predict, measure, and manipulate reality. -/- 1. Mathematics and Logical Thought – Mathematical reasoning mirrors the logical structures of conscious thought. It allows for problem-solving, abstraction, and deductive reasoning. -/- 2. Mathematics and Scientific Discovery – From physics to neuroscience, mathematical models describe the fundamental principles governing existence, furthering our understanding of consciousness itself. -/- 3. Mathematics and Artificial Intelligence – The development of AI and machine learning relies on mathematical principles, raising questions about whether artificial systems can achieve a form of consciousness. -/- If consciousness operates under universal laws, mathematics may be the key to deciphering its principles. -/- Information and Knowledge: The Evolution of Consciousness -/- Information is the raw material from which knowledge is constructed. The accumulation, processing, and application of information drive the expansion of consciousness. -/- 1. Memory and Learning – The ability to store and recall information enhances cognitive abilities, shaping an individual’s awareness of the world. -/- 2. Collective Intelligence – The sharing of information across societies leads to cultural evolution, technological advancements, and the refinement of knowledge. -/- 3. External Storage of Consciousness – Books, digital databases, and AI systems act as extensions of human consciousness, preserving and expanding knowledge beyond biological limitations. -/- The more information consciousness can process, the more it expands its awareness and potential for discovery. -/- New Discoveries: The Feedback Loop of Expanding Consciousness -/- Scientific and philosophical discoveries continuously reshape how consciousness understands itself and the universe. Each breakthrough: -/- 1. Expands Perception – Tools like microscopes and telescopes extend human awareness beyond natural sensory limitations. -/- 2. Challenges Established Beliefs – Paradigm shifts force consciousness to adapt to new realities, redefining truth and understanding. -/- 3. Integrates Technology and Consciousness – Advancements in neuroscience, quantum mechanics, and artificial intelligence suggest that consciousness may be an emergent phenomenon shaped by computational and environmental factors. -/- The cycle of discovery feeds back into language, mathematics, and knowledge, leading to new levels of understanding and further expanding consciousness. -/- Conclusion: Consciousness as a Self-Perpetuating System -/- The relationship between language, mathematics, information, knowledge, and discovery forms a self-reinforcing loop that drives the evolution of consciousness. Each component influences and strengthens the others, creating a dynamic system of intellectual and cognitive growth. -/- Language provides structure for thought and communication. -/- Mathematics reveals underlying patterns of reality and enhances logical reasoning. -/- Information and knowledge serve as the building blocks of learning and awareness. -/- New discoveries expand the limits of consciousness, redefining human potential. -/- If consciousness operates under natural laws, this interconnected system may represent the fundamental process by which awareness evolves. The more humanity advances in these areas, the more profound our understanding of consciousness—and reality itself—becomes. -/- . (shrink)

Advocates of psychedelic drugs argue that they can induce experiences that are of great spiritual and philosophical value, and that they have the potential to ‘expand consciousness.’ But can drugs, as William James (1842-1910), Aldous Huxley (1894- 1963), and Timothy Leary (1920- 1996) argue, allow us to see beyond the horizon of ordinary perception — that is, see things as they really are? To put the philosophical question more generally, can an artificial change (by the means of drugs, electrical stimuli, (...) or psychosurgery) to the brain— to the mind’s material foundations — reveal knowledge through the resulting experience? And could such a change actually provide an authentic religious experience, or rather, knowledge of what it is like to have an authentic religious experience? Or are such claims of instant enlightenment merely a mystical façade? (shrink)
