There are at least three interpretations that attempt to read from the Sense-Certainty Chapter a Hegelian theory of indexicals. First, the Impossibility of Singular Reference Reading understands Hegel as excluding in principle the possibility of any linguistic cognition of individuals. Second, the Theory of Reference Reading criticizes the first reading and interprets from Hegel the classical idea of direct reference theory. Third, Brandom’s Anaphoric Theory Reading suggests an alternative explanation while still defending the possibility of knowledge of individuals (...) in Hegel. I criticize the first two readings and argue that the third is the most exegetically and philosophically adequate interpretation. The first interpretation attempts to ascribe to Hegel a sort of skepticism, but this can be at most in a very restricted sense successful and the skepticism constructed in such a way is too trivial to refute Hegel’s position. The second reading is more adequate in that it does not fall into the error that the first one committed, but is still flawed because it introduces a subject-object or mind-world dualism that Hegel denies. The third reading has great advantages compared to the first two readings in terms that it provides a suitable account of indexical knowledge on individuals while avoiding skepticism and dualism which arise in the former readings.

In Sense-certainty, the being of the particular object of sense was found to belong to the universality - of consciousness. This relationship between the universal truth of the object and its sensuous determinate particularity is called the Thing of Perception, basically a Thing and its perceived properties. However, in perception it was concluded that the particular Thing is ultimately resolved into the unconditioned universality of the Understanding. Thus in both Sense-certainty and Perception the particular object (...) or Thing proves to be essentially universality. It is important to recollect the development that has taken place up to this point, i.e., the various moments and movements of thinking that constitute the activity, or dynamic essence, of what is called, in totality, consciousness or knowing. The full explication of what consciousness is in its completely developed form has not yet been reached, but only what may broadly be referred to as the first three stages (Sense-certainty, Perception, Understanding) in the complete activity that will be necessary and sufficient to adequately comprehend consciousness. When the movement of consciousness is completed, the development will continue onward to the stages of Self-consciousness, Reason, and Spirit. (shrink)

The object of study is consciousness. The activity of consciousness is called knowing. The study of a subject may only begin with immediacy, because a beginning implies that there is no prior mediation, i.e. no explicit differences or determinations. Such a beginning is mere being — what immediately is. Being as such is pure generality. Since consciousness is not a physical object that appears before the eyes like a tree, it has to be treated as an object of thought or, (...) as it is said, “before the mind’s eye.” When consciousness apprehends itself as an object, then the objective consciousness must be in the form of something immediate. Thus apprehension is in a purely receptive mode without intervention of explicit thinking or comprehension. So the first passive observation of immediate consciousness as an object reveals a consciousness that simply is. The knowing activity of this immediate consciousness is also immediate so that what it knows is immediate knowledge. Because of this immediacy (non-differentiation) there is no distinction made between consciousness and what it knows. A consciousness thus absorbed in the wealth of the world, i.e. in what it sees, hears, smells, touches and tastes, is sensuous consciousness or sense-certainty. The word ‘certainty’ implies immediate knowledge that something is. Thus sensuous certainty of something means that it is, and no further thought determination interrupts that immediate knowledge. “That” refers only to indeterminate being, whereas “what” refers to the determination of that being — these are two distinct indexicals. So here in sense-certainty only that is implied. Consciousness itself is just another immediate ‘this’ opposed to all the other immediate individual ‘thises’ that are encountered by the senses. This immediate consciousness is called “I.” Certainty is the connection between “I” and its object, but this connection or mediation is transparent (invisible) to or not known by sense-certainty in its immediacy.

In this paper, I explore the largely ignored ethical dimension in the first section of Hegel’s Phenomenology of Spirit, Sense-certainty, which tends to be understood exclusively as an epistemological critique of sense-data empiricism. I approach the ethical aspect of the chapter through Hegel’s analysis of language, there, as unable to refer to individual things. I then show that the position Hegel analyses is akin to the one presented by Thomas Hobbes in his Leviathan, as well as in (...) his De Corpore, and which serves to ground his naturalistic ethics. The linguistic juxtaposition consequently allows me to relate the ethics of sense-certainty to Hobbes, not only to his “shallow” empiricism, as Hegel puts it, but to the ethical vision Hobbes presents in his state of nature.

Why do we tend to think that phenomenal consciousness poses a hard problem? The answer seems to lie in part in the fact that we have the impression that phenomenal experiences are presented to us in a particularly immediate and revelatory way: we have a sense of acquaintance with our experiences. Recent views have offered resources to explain such persisting impression, by hypothesizing that the very design of our cognitive systems inevitably leads us to hold beliefs about our own (...) experiences with certainty. I argue against this kind of “designed certainty” views. First, I claim that it is doubtful that we really hold beliefs about our own experiences with certainty—in any sense of certainty that would make our phenomenal beliefs special. Second, I claim that, even if it were the case that we hold beliefs about experiences with certainty, this would fall short of explaining our sense of acquaintance. (shrink)

We ordinarily assume that we have reliable knowledge of our immediate surroundings, so much so that almost all the time we entrust our lives to the truth of what we take ourselves to know, without a moment’s thought. But if, as Karl Popper and others have maintained, all our knowledge is conjectural, then this habitual assumption that our common sense knowledge of our environment is secure and trustworthy would seem to be an illusion. Popper’s philosophy of science, in particular, (...) fails to do justice to the distinction we ordinarily draw between secure knowledge and mere conjecture. But Popper’s philosophy of science, in particular his attempted solution to the problem of induction, is defective. It fails to take into account that physics, in only accepting unified theories, even though endlessly empirically more successful disunified rivals are always available, makes the persistent metaphysical assumption that all disunified theories are false. Once this point is acknowledged, it becomes clear that a new conception of scientific method is required which sees science as making a hierarchy of metaphysical assumptions concerning the comprehensibility and knowability of the universe. This provides a framework of relatively unproblematic assumptions and associated methods of science within which much more problematic assumptions and associated methods can be critically assessed and improved. This hierarchical view seems at first to intensify the problem of distinguishing certainty from conjecture, in that it emphasizes that scientific knowledge, and even humble common sense knowledge, contain usually unacknowledged cosmological conjectures. But actually it explicates the basis we have for drawing the distinction between trustworthy knowledge and mere conjecture, and even goes some way towards providing a rationale for this distinction, in so far as one exists.

This book explores a question central to philosophy--namely, what does it take for a belief to be justified or rational? According to a widespread view, whether one has justification for believing a proposition is determined by how probable that proposition is, given one's evidence. In this book this view is rejected and replaced with another: in order for one to have justification for believing a proposition, one's evidence must normically support it--roughly, one's evidence must make the falsity of that proposition (...) abnormal in the sense of calling for special, independent explanation. This conception of justification bears upon a range of topics in epistemology and beyond. Ultimately, this way of looking at justification guides us to a new, unfamiliar picture of how we should respond to our evidence and manage our own fallibility. This picture is developed here.

A common sense view is illustrated by Doubting Thomas, and surfaces in many philosophical and psychological writings : Touching is better than seeing. But can we make sense of this privilege? We rule out that it could mean that touch is more informative than vision, more ‘objective’ or more directly in contact with reality. Instead, we propose that touch offers not a perceptual, but a metacognitive advantage: touch is not more objective than vision but rather provides comparatively higher (...) subjective certainty.

_ Source: _Volume 6, Issue 2-3, pp 120 - 142 This paper aims to contribute to the debate over epistemic versus non-epistemic readings of the ‘hinges’ in Wittgenstein’s _On Certainty_. I follow Marie McGinn’s and Daniele Moyal-Sharrock’s lead in developing an analogy between mathematical sentences and certainties, and using the former as a model for the latter. However, I disagree with McGinn’s and Moyal-Sharrock’s interpretations concerning Wittgenstein’s views of both relata. I argue that mathematical sentences as well as certainties are (...) true and are propositions; that some of them can be epistemically justified; that in some senses they are not prior to empirical knowledge; that they are not ineffable; and that their primary function is epistemic as much as it is semantic.

In Leibniz’s New Essays stands out, within many important topics, his doctrine of innate ideas, which supposes the division between sense knowledge and innate knowledge and implies the distinction between truths of reason and truths of fact. That doctrine is particularly relevant for Leibniz’s philosophy, but implicitly entails the epistemological difference between belief, on one hand, and certainty, on the other. In this paper I outline, according to my interpretation, how Leibniz explains that humans can have certainty (...) about innate ideas. This topic is important because if Leibniz demonstrates the possibility of having certainty of those ideas, then, it is feasible to believe in its existence. However, if his explanation is unsatisfactory his metaphysical doctrine would be seriously weakened and, at the same time, both skepticism and Locke’s empiricist doctrine would be reinforced.

Some people insist that they are dead. Rather than starting with the usual assumption that delusions are ‘false beliefs about external reality’ I want to consider how interpreting their claim as a report of a certain kind of anomalous experience assists us in understanding why they are certain, why their claim is immune from evidence to the contrary, and why they do not act in ways we would expect were they to believe their claim to be true of the world. (...) While this helps us understand cases where people do not act on their delusions, more must be said about the people who do act on their delusions. I shall attempt to describe a process where an intense anomalous experience leads to a context-specific narrowing of attention. The ultimate result of this is that the appearance / reality distinction becomes lost in the context of the anomalous experience. The sense of conviction that would be appropriately associated with a report of experience thus becomes inappropriately associated with a claim about external reality. While there have been efforts to provide cognitive therapy for delusional subjects such therapy seems to be based on the notion that confronting them with their contradictions will assist in weakening their sense of certainty about the delusional utterance. I consider whether more progress could be made via empathetic validation of the sense of certainty which is appropriate when associated with the person’s anomalous experience. (shrink)

I argue that being wide awake is an epistemic virtue which enables me to recognize immediately that I'm wide awake. Also I argue that dreams are imaginings and that the wide awake mind can immediately discern the difference between imaginings and vivid sense experience. Descartes need only pinch himself.

I can be wrong about things I seem to perceive; the conditions might lead me to be mistaken about them. Since I can't rule out the possibility that the conditions are misleading, I can't be sure that I am perceiving this thing in my hand correctly. But suppose that I am able to examine it actively—handling it, looking closer, shining a light on it, and so on. Then, my level of uncertainty goes down; in the limit it is eliminated entirely. (...) Of course, I might be mistaken because I am a brain in a vat, or because some other sceptical scenario obtains. But sceptical scenarios apply not just to this thing in my hand, but to everything all at once. Define "empirical certainty" as the absence of the kind of doubt that spreads to all empirical states of affairs. Sensory exploration, or active examination, can in principle lead to empirical certainty. (shrink)

This thesis develops an account of ethics called the Linguistic Perspective, which is realist in a practical, non-theoretical sense, and is rooted Wittgenstein’s 'On Certainty'. On this account, normativity is intrinsic to human action and language; the norms of ethics are the logical limits of the most basic, unassailable concepts that practical reasoning requires for intelligibility. Part I lays the groundwork for this account by developing a Tractarian Reading of 'On Certainty'. Here, I contend that 'On (...) class='Hi'>Certainty' is primarily concerned with the logical requirements and limits of language, and like the 'Tractatus' it develops these concerns in a realist direction. 'On Certainty', I argue, does so by advancing three key claims about logic: Everything descriptive of a language-game is part of logic; the boundary between logical and empirical propositions is not sharp; logic is founded on action. I investigate these claims, with particular emphasis on how natural human reactions provide logical conditions for the possibility of language. Hinge propositions, I argue, are rooted in these reactions; they point us to the limits of intelligibility of our concepts, though these limits are vague and inarticulable. In Part II, I discuss the practical syllogism and its validity. I argue that practical reasoning is distinct from theoretical reasoning and embodies a different standard of logical validity for inference. This standard is not strict and narrow, but creative and wide open; furthermore, it is an intrinsically ethical standard. Then, I advance my Linguistic Perspective on ethics, according to which human reactions provide the conditions for ethical normativity, just as they do for language. I argue that we can access ethical norms by reflecting on those linguistic concepts that are rooted in the most basic patterns of action, and by identifying the norms of behaviour that ensure the development of those concepts without contradiction.

In the preface to On Certainty Anscombe and von Wright say that in 1949 Malcolm suggested to Wittgenstein to think again about Moore’s “Defense of Common Sense” (1925) and “Proof of an External World” (1939). Malcolm himself had written on the issue in “Defending Common Sense” (1949). In the preface to the Philosophical Investigations Wittgenstein quotes Nestroy saying that there is usually very little progress in philosophy. But I think some progress has been made from Moore and (...) Malcolm to Wittgenstein regarding skepticism. There is more awareness of practice and perspective and this opens the discussion in novel ways. But it also gives rise to new problems, in particular of morality and relativity. (shrink)

A popular account of luck, with a firm basis in common sense, holds that a necessary condition for an event to be lucky, is that it was suitably improbable. It has recently been proposed that this improbability condition is best understood in epistemic terms. Two different versions of this proposal have been advanced. According to my own proposal :361–377, 2010), whether an event is lucky for some agent depends on whether the agent was in a position to know that (...) the event would occur. And according to Stoutenburg :319–334, 2015, Synthese, 1–15, 2018), whether an event is lucky for an agent depends on whether the event was guaranteed or certain to occur in light of the agent’s evidence. In this paper, I argue that we should prefer the account in terms of knowledge over that in terms of evidential certainty. (shrink)

“Our later and more critical philosophies are mere fads and fancies compared with this natural mother-tongue of thought”, says William James in his lecture on common sense. The deep bond connecting language, common sense and nature is also one of the main concerns of the later Wittgenstein. The aim of this paper is to compare the two philosophers in this respect, particularly focusing on James’ Pragmatism and on Wittgenstein’s On Certainty. Similarities, but also differences, will be highlighted. (...) A further element will be offered by the analysis of a fragment of Wittgenstein’s Nachlass, which anticipates his image of the river-bed of thought through the critique of James’ stream of thought. By means of this comparison, I will question Wittgenstein’s explicit refusal of pragmatism. I will argue that his late philosophy can be said to be even more pragmatist than James’, in that it delineates a conception of the common sense certainties which shape our Weltbild (world-picture) as practically, and not merely epistemically, connected to our life.

Meaning, for example Sam's meaning that it rains by saying "es regnet", forms of life and the senses of propositions or thoughts are three categories that loom large in Wittgenstein's writings on language and mind. How do they stand to one another, how are they connected? The question was addressed before Wittgenstein by the realist phenomenologists, Scheler, Hartmann and Ortega as well as by the Viennese philosopher and psychologist, Karl Bühler. Like Wittgenstein, these philosophers were quite clear that the category (...) to which meaning belongs and the category to which belong the senses of individual propositions cover a great variety of cases and that a form of life has many dimensions. Language is only one of the phenomena which go to make up human life or culture. The acts and activities of a person are one thing, the acts and activities of interacting persons another thing and the contents of both yet another thing. (shrink)

Sense-certainty is the consciousness that Truth (what is/being) lies in particular external objects. For example, considering that the mountain is true, the tree is true, and so on. But truth is not immediate. Truth is necessarily mediated, i.e. a result, implying that it is arrived at. Thus, if a crime is claimed against someone before a judge, the judge does not accept it immediately as true. The truth of the claim has to be established, arrived at, through due (...) process of presenting evidence, circumstances and arguments. The naïve realist accepts the evidence of his/her senses as true, as does the empirical scientist, but is unaware of the fact that there is process involved in making that determination. Divine Reason acts within all of creation, in which Man participates to some finite degree and, accordingly, is able to articulate that in the world. It is not so clear-cut as this, however, as the understanding would like it to be. The principle of the identity of identity and difference blurs the distinctions between God and Man so that, although the distinction is there, identity is also to be accounted for. It is this principle of simultaneous oneness and difference beyond understanding, and comprehensible only to what Hegel calls Speculative Reason that unlocks the door to the sphere of Spirit, or Absolute Knowledge. This is of course the broader perspective—the real science is in the details. Study of the Phenomenology is useful because it deals with the perspective of Reality from within consciousness and gradually leads to the comprehension of the Concept of which consciousness is only one aspect.

According to Danièle Moyal-Sharrock, Wittgenstein’s On Certainty presents a theory of hinges, and hinges have a role to play in a foundationalist epistemology (2013). Michael Williams (2005) and Annalisa Coliva (2013 ) have claimed that the hinges are not suitable to play such a role as they are not shared universally. Moyal-Sharrock has replied that a subset of the hinges is suitable to play such a role: the “universal” hinges. I argue that for Moyal-Sharrock’s reply to be sustained, she (...) must construe the set of universal hinges much more narrowly than she does currently. For instance, Moyal-Sharrock claims that “I have a brain” is a universal hinge, which consigns people who know nothing about brains to stand outside the bounds of sense. I also provide a novel way of thinking about the universal hinges, which I argue is better textually motivated than Moyal-Sharrock’s own way, and which provides a set of hinges more suitable to play a role in foundationalist epistemology.

Matters of Certainty and Conviction. In the section on certainty, Shaw puts forth a proof of the external world, and considers topics such as change, difference, time, consciousness, substance and quality.

Wittgenstein’s concepts shed light on the phenomenon of schizophrenia in at least three different ways: with a view to empathy, scientific explanation, or philosophical clarification. I consider two different “positive” wittgensteinian accounts―Campbell’s idea that delusions involve a mechanism of which different framework propositions are parts, Sass’ proposal that the schizophrenic patient can be described as a solipsist, and a Rhodes’ and Gipp’s account, where epistemic aspects of schizophrenia are explained as failures in the ordinary background of certainties. I argue that (...) none of them amounts to empathic-phenomenological understanding, but they provide examples of how philosophical concepts can contribute to scientific explanation, and to philosophical clarification respectively.

In the sense-certainty chapter of the Phenomenology of Spirit, we find one of Hegel’s famous puns, which utilizes homophonic affinities and differences between the verb beiherspielen and the noun Beispiel. I argue that the effect of this pun is that the word Beispiel acquires, beyond its usual meaning of ‘example’ or ‘instance’, the meaning of a play of something inessential, a play in passing. After reviewing all available translations into English, I suggest that, in order to preserve this (...) wordplay, one can translate Beispiel as ‘by-play’. Furthermore, I analyse other occurrences of the word beiherspielen in the Phenomenology and elsewhere in Hegel’s texts. Next, I focus on the crucial importance of this pun for Derrida’s interpretation and critique of Hegel’s dialectic. Only for a certain loose translation of beiherspielen does Derrida’s reasoning appear plausible. I conclude with a discussion of the ideal of terminological uniformity in translating Hegel’s texts. In preserving the wordplay by translating Beispiel as ‘by-play’, one is forced to sacrifice the uniformity of translation. (shrink)

Our senses provide us with information about the world, but what exactly do they tell us? I argue that in order to optimally respond to sensory stimulations, an agent’s doxastic space may have an extra, “imaginary” dimension of possibility; perceptual experiences confer certainty on propositions in this dimension. To some extent, the resulting picture vindicates the old-fashioned empiricist idea that all empirical knowledge is based on a solid foundation of sense-datum propositions, but it avoids most of the problems (...) traditionally associated with that idea. The proposal might also explain why experiences appear to have a non-physical phenomenal character, even if the world is entirely physical. (shrink)

The consciousness of sense-certainty proves itself to be dialectical. It starts out with the certainty that its object is a singular immediate being. But it is just this ‘singular immediate being’ that turns around into its opposite to become a universal – i.e. it is true not only for a single but all individual objects since everything is a ‘singular immediate being’. ‘Every individual is different’ because each has free will and is independent of others. If this (...) is universally true then it dialectically turns around to its opposite and becomes ‘everyone is the same.’ This is called “negative movement” or dialectical because each side of the individual-universal relation negates itself to become the other. Immediate consciousness is called ego. The consciousness of immediate sense-certainty is not aware that ego is related to the object which it considers as immediately being. The admission of relationship cancels immediacy because a relation is something that mediates between two things that unites them, i.e. changes them from two independent beings into a unity or oneness. This change is negation, thus the many-ness is negated to become one-ness or unity as a relation. Of course the many-ness is not destroyed in a relation, or the relationship itself could not exist as such. This is the nature of negation – it does not annihilate but sublimates; unity implies that two or more things have been united, i.e. the explicit multiplicity is sublimated (becomes implicit) in the concept of unity. The change in going from one moment to another in this movement or process is called experience (as discussed in the November 2011 issue). [1] Taken together these experiences of consciousness are called its history. It is not a history of the world, or the development of consciousness through historical time. It is simply the experience or change due to the movement of thought explained previously – involving the purely philosophical, logical or conceptual events. The series of these experiences is called its history. (shrink)

This paper walks through four different approaches to Hegel's notion of Consciousness in the Phenomenology of Spirit. Through taking four different approaches our aim is to explore the multifaceted nature of the phenomenological movement of consciousness. The first part provides an overview of the three chapters of the section on Consciousness, namely Sense-Certainty, Perception and Force and the Understanding, attempting to unearth the implicit logic that undergirds Consciousness’ experience. The second part focuses specifically on the shape of (...) class='Hi'>Sense-Certainty, providing an analysis of the movement from Sense-Certainty to Perception from a neuroscientific view. Thirdly, we consider an inferentialist reading of the chapters on Consciousness which has been made popular by Robert Brandom. We think that while this view elucidates the connection that Hegel draws between meaning and use, it fails to account for the vital place of immediacy in each of the shapes. Finally, the fourth part suggests that Hegel’s notion of Consciousness improves the reading of tragedy he develops in chapters 5 and 7 of the Phenomenology. While many critics have noted that Hegel fails to do justice to tragic experience, Consciousness contains an epistemology that develops analogously to the heroes of ancient tragedy. Each approach in this paper comes at Hegel’s description of the journey of Consciousness from a different angle, and together they paint a multi-layered picture of a highly important part of Hegel’s corpus.

The initial one-third of the paper is devoted to exposing the first chapter (“Sense-Certainty”) of Hegel’s PHENOMENOLOGY OF SPIRIT as a thesis about reference, viz., that singular demonstrative reference is impossible. In the remainder I basically argue that such a view commits one to radically undermining our conceptions of space, time, and substance (concrete individuality), and rests on the central mistake of construing <this> on the model of a predicable (or property).

In this paper I focus Hegelian conception of limit trying to clarify its main features. I begin locating Hegel’s philosophy in the broader philosophical context of German Idealism, understanding it as the intellectual movementconcerned with the project of providing a transcendental deduction of the Absolute. Having this as a background, Iexamine Hegelian critique of Kantian philosophy, mainly in the “Introduction” of Phenomenology of Spirit, and I conclude the paper testing the way I elucidated the problem of limit in this paper showing how this notion can beused to interpret the treatment of “sense certainty” in Hegel’s Phenomenology of Spirit.

Consciousness in the form of sense-certainty wants to apprehend its particular object as being-there (existing). But as demonstrated in previous articles in this series, the only truth of sense-certainty is merely that something is, and because everything is, being is universal. Here it will be shown that perception is the consciousness of the universal as the truth of a particular being. And because universality is the very principle of perception, both object and the I are also (...) universal. Because this universality is arrived at through a mediating process or thinking, it is not just an immediate ‘happening’ as is found in sense-certainty - rather, it proves to be a logically necessitated content.

A framework is developed for understanding what is “taken for granted” both in philosophy and in life generally, which may serve to orient philosophical inquiry and make it more effective. The framework takes in language and its development, as well as mathematics, logic, and the empirical sphere with particular reference to the exigencies of life. It is evaluated through consideration of seven philosophical issues concerned with such topics as solipsism, sense data as the route to knowledge, the possible reduction (...) of geometry to logic, and the existence and status of human rights. Various dichotomies and the notion of continuity are evidently highly strategic. (shrink)

It is sometimes claimed that in his 1912 work, "The Problems of Philosophy" (POP), and possibly as early as “on Denoting”, Russell conceives of the mind's acquaintance with sense-data as providing an indubitable or certain foundation for empirical knowledge. However, although he does say things suggestive of this view in certain of his 1914 works, Russell also makes remarks in POP that conflict with any such broadly "Cartesian" interpretation of this work. This paper attempts to resolve this apparent tension, (...) while also offering a close examination of Russell's views on the nature of acquaintance and their relationship to certain ideas in William James.

In the text the author tries to investigate Wittgenstein’s notions of action, practice and pragmatism in his book On Certainty. An attempt is made to sketch the criterion of Wittgenstein’s analysis of certainty and to define the crucial concepts such as world-picture, practice, certainty and justification. The analysis shows that Wittgenstein applies a specific form of pragmatic solution to the problem of justification, which after all, can and should be called a kind of pragmatismus. This is the (...) subject of the first and the second part of the text. The third part shows the application of this pragmatic theory of justification to Wittgenstein’s refutation of scepticism. The author suggests that his pragmatic analysis of certainty presents an adequate means for the refutation of scepticism. However, his anti-scepticism is situated in the tradition of common sense and ordinary language philosophy and epistemology (Moore, Chisholm, Lehrer, Austin, Grice, Strawson, etc.). In the conclusion the author applies this anti-sceptical solution to the so called rule-following problem (as stated in Kripke’s work) and shows that there are some far reaching consequences of this interpretation of Wittgenstein’s later work to his position on language, learning, ontology and knowledge.

In this paper, I discuss the legitimacy of using the term “to know” in morality and I develop an approach based on Kantian morality. In my analysis, I take the notion “to know” in the sense that Timothy Williamson does. That is to say, I regard it in opposition to the perspectives that claim “knowledge is jus-tified true belief”. Therefore, in the first part, I briefly introduce “knowledge first epistemology”. In the second part, I build a perspective pointing to (...) the strong correlation between acting and knowing. After that, I provide an analysis of Kantian morality in connection with my discussion. I show how Kant argues for a lawful certainty in morality that allows us to use the verb “know” (in the sense that is evaluated in the first part of this paper). In the next part, I comment on the un-analyzability of knowing in the practical sphere with reference to free will. In my conclusion, upon a general review of the paper, I introduce very briefly an alternative epistemology from Islamic thought regarding the theoreti-cal and practical sphere distinctions. (shrink)

Clear and distinct perception is the centrepiece of Descartes’s philosophy — it is the source of all certainty — but what does he mean by ‘clear’ and ‘distinct’? According to the prevailing approach, what it means for a perception to be clear is that its content has a certain objective property, like truth. I argue instead that clarity is at least partly a subjective, phenomenal quality whereby a content is presented as true to the perceiving subject. Clarity comes in (...) degrees. Any weak degree of clarity, available to the senses, can be merely subjective, since what it presents as true may not actually be true. But complete clarity, available to intellectual perception, has an objective dimension, since what it presents as true is always some truth, some bit of reality. Further, I argue that the other perceptual qualities that Descartes identifies — obscurity, confusion, and distinctness — are all defined in terms of clarity. Of particular note is the fact that distinctness is not a positive feature to be added to clarity: a distinct perception is just a completely clear perception. (shrink)

Recent work has argued that belief is weak: the level of rational credence required for belief is relatively low. That literature has contrasted belief with assertion, arguing that the latter requires an epistemic state much stronger than (weak) belief---perhaps knowledge or even certainty. We argue that this is wrong: assertion is just as weak as belief. We first present a variety of new arguments for this, and then show that the standard arguments for stronger norms are not convincing. Finally, (...) we sketch an alternative picture on which the fundamental norm of assertion is to say what you believe, but both belief and assertion are weak. To help make sense of this, we propose that both belief and assertion involve navigating a tradeoff between accuracy and informativity, and so it can makes sense to believe/say something you only have weak evidence for, if it is informative enough.

The purpose of this study is exposition on the themes of method and mysticism in the work of Simone Weil. Nearly a decade before the onset of her first mystical experience, Weil developed a method to be rigorously applied in daily philosophical reflection. She outlines this method in her dissertation on Descartes (1929-1930). I examine the question of how Weil applied method to philosophical reflection on her mystical experiences (onset 1938-1939). I analyze Weil’s mystical experiences as a type of transformative (...) experience in L. A. Paul’s strict sense of the term. On Paul’s view, an experience is transformative if it is both epistemically and personally transformative. An experience is epistemically transformative if the only way to know what it is like to have it is to have it yourself. An experience is personally transformative if it changes your point of view, including your core preferences (Paul, 2014). I present a thought experiment and textual evidence to motivate the claim that Weil’s mystical experiences meet Paul’s conditions for transformative experience. I then propose two epistemological facts that can be revealed by philosophical reflection on mystical experience. First, it is possible to read meaning erroneously in the appearances of things. Second, it is possible to come to hold to the certainty of a conviction for reasons that elude the intellect. My findings suggest that Weil’s late views on philosophy accommodate these two epistemological constraints, thereby demonstrating a possible connection between Weil’s mystical experiences and her mature views on the nature, scope, and proper method of philosophy. However, my preliminary findings also suggest that Weil’s early work on method may have anticipated these epistemological obstacles prior to the onset of her first mystical experience. Thus, further exposition of Weil’s method is needed to support or elucidate the claim (Rozelle-Stone and Davis, 2021) that Weil’s epistemology underwent significant changes because of her mystical experiences.

The fact of religious diversity is vital for the philosopher of religion but also, to some extent, for the believer of a given faith. It takes place in such a dimension in which the views of a given believer or the meaning of the practice of a given religion presupposes the truthfulness of specific claims concerning a given religion or the beliefs included in it. If now on the part of the philosopher of religion or the followers of another religion, (...) there is a direct or indirect challenge to such a key proposition, religious disagreement with epistemic dimension is involved. At the same time, it is not the case that any religious diversity is a case of epistemically significant religious dissent. The paper, by distinguishing different aspects of religions and functions performed by religion, tries to show in which situations religious diversification leads to religious disagreement. Both the follower of religion and the philosopher of religion can and should seek the truth in matters of crucial importance to religion. The difference is that the follower of a given religion is more interested in the salvific and practical functions of religion, along with the associated sense of value and meaningfulness of life and, to a lesser degree, the theoretical certainty that her religion is correct at crucial points. On the other hand, the achievement of ‘the soteriological’ purpose of religion based on false belief is impossible, just as the meaningfulness of life 'based on the sand and not on the rock’. It is because the false foundation is devoid of higher value. That is why there is a community of a philosopher of religion and a follower of a given religion to search for the truth of it. (shrink)

Recent work in philosophy and cognitive science shows that knowledge is the norm of our social practice of assertion, in the sense that an assertion should express knowledge. But why should an assertion express knowledge? I hypothesize that an assertion should express knowledge because the point of assertion is to transmit knowledge. I present evidence supporting this hypothesis.

The new narcissist is haunted not by guilt but by anxiety. He seeks not to inflict his own certainties on others but to find a meaning in life. Liberated from the superstitions of the past, he doubts even the reality of his own existence. Superficially relaxed and tolerant, he finds little use for dogmas of racial and ethnic purity but at the same time forfeits the security of group loyalties and regards everyone as a rival for the favors conferred by (...) a paternalistic state. His sexual attitudes are permissive rather than puritanical, even though his emancipation from ancient taboos brings him no sexual peace. Fiercely competitive in his demand for approval and acclaim, he distrusts competition because he associates it unconsciously with an unbridled urge to destroy. Hence he repudiates the competitive ideologies that flourished at an earlier stage of capitalist development and distrusts even their limited expression in sports and games. He extols cooperation and teamwork while harboring deeply antisocial impulses. He praises respect for rules and regulations in the secret belief that they do not apply to himself. Acquisitive in the sense that his cravings have no limits, he does not accumulate goods and provisions against the future, in the manner of the acquisitive individualist of nineteenth-century political economy, but demands immediate gratification and lives in a state of restless, perpetually unsatisfied desire.

Lisa Tessman (2016: 164) recounts the case of a Jewish mother, running from Nazis, who faced a terrible choice. She could (a) drown her infant, or (b) accept the virtual certainty that her baby’s cries would doom the refugee group she was fleeing with. Given those options, (b) is worse. If the whole group is discovered, many will die, including the infant. Still, preemptively drowning a baby—indeed one’s own baby—is a terrible act. To make sense of cases like (...) this, Tessman turns to the concept of moral failure: an act that violates an important moral value such that the loss cannot be fully redeemed by gains elsewhere. I will argue that criminal justice needs a moral framework like Tessman’s. It needs to make sense of the fact that some options are genuinely better than others, without letting honorifics like ‘justice’ obscure the equally important fact the best available option might be terrible. More specifically, I will argue that when punishment involves prison, as it often does, it is a moral failure. It can be justified only in the sense that preemptively drowning an infant can be justified: like the fleeing mother, society might on some terrible occasions find itself with no better alternative.

How is what we believe related to how we act? That depends on what we mean by ‘believe’. On the one hand, there is what we're sure of: what our names are, where we were born, whether we are sitting in front of a screen. Surety, in this sense, is not uncommon — it does not imply Cartesian absolute certainty, from which no possible course of experience could dislodge us. But there are many things that we think that (...) we are not sure of. For example, you might think that it will rain sometime this month, but not be sure that it will. Both what we're sure of and what we think have important normative connections to action. But the connections are quite different. This paper explores these issues with respect to assertion, inquiry, and decision making. We conclude by arguing that there is no theoretically significant notion of ‘full belief’ intermediate in strength between thinking and being sure. (shrink)

Some metaphysicians believe that existence debates are easily resolved by trivial inferences from Moorean premises. This paper considers how the introduction of negative Moorean facts—negative existentials that command Moorean certainty—complicates this picture. In particular, it shows how such facts, when combined with certain plausible metaontological principles, generate a puzzle that commits the proponents of this method to a contradiction.

The Cartesian thesis that some justifications are infallible faces a gradation puzzle. On the one hand, infallible justification tolerates absolutely no possibility for error. On the other hand, infallible justifications can vary in evidential force: e.g. two persons can both be infallible regarding their pains while the one with stronger pain is nevertheless more justified. However, if a type of justification is gradable in strength, why can it always be absolute? This paper explores the potential of this gradation challenge by (...) rejecting Fumerton's recent ‘semantic decision' solution. On Fumerton's suggestion, the putative gradation of infallible justifications is essentially semantic. It concerns only how we use the relevant term but not how well we perceive the truth. Regardless of its intuitive appeal, Fumerton's solution does not cover all the related situations. There is an irreducibly epistemic sense in which infallible justifications vary in degrees.

In the opening chapter of his Essay Concerning Human Understanding, John Locke explains that the self-understanding or self-measure of the human mind includes an account of the mind’s limits, and so the mind’s self-understanding can provide adequate grounds for intellectual self-moderation or self-control: “If we can find out, how far the Understanding can extend its view; how far it has Faculties to attain Certainty; and in what Cases it can only judge and guess, we may learn to content our (...) selves with what is attainable by us in this State.” Furthermore: “If we can find out those Measures, whereby a rational Creature put in that State, which Man is in, in this World, may, and ought to govern his Opinions, and Actions depending thereon, we need not be troubled, that some other things escape our Knowledge.” Compared to Locke’s Essay Concerning Human Understanding, Fichte’s Wissenschaftslehre may appear to exemplify the very opposite of intellectual modesty and self-control. Unlike Locke, Fichte argues that a true system of knowledge should not seek to limit or moderate itself by reference to what is allegedly unknowable outside of it. A true system of knowledge, writes Fichte, “. . . only has to agree with itself. It can be explained only by itself, and it can be proven - or refuted - only on its own terms.” Furthermore, Fichte suggests that an appreciation of his system of knowledge requires not modesty in his readers, but rather an implicit sense of superiority: “I wish to have nothing to do with those who, as a result of protracted spiritual servitude, have lost their own selves and, along with this loss of themselves, have lost any feeling for their own conviction . . .” In this essay, I shall seek to show that, contrary to initial impressions, it is Fichtean idealism, and not Lockean (or any similar) realism, that is truly modest. According to my account, Locke’s explicit declarations concerning the modesty and limitedness of his own project exhibit a certain ignorance concerning the genuine problems at issue. In his claim to be modest, the realist Locke professes to know more than he actually does, and thus manifests his own immodesty. By contrast, the idealist Fichte must refrain from such direct claims to modesty and must appear to be immodest, precisely because he has a greater understanding of how radically limited human knowledge always is. Like Plato’s Charmides, Fichte realizes that any explicit claim to self-limitation and self-moderation would actually give lie to itself. (shrink)

I intend to: a) clarify the origins and de facto meanings of the term relativism; b) reconstruct the reasons for the birth of the thesis named “cultural relativism”; d) reconstruct ethical implications of the above thesis; c) revisit the recent discussion between universalists and particularists in the light of the idea of cultural relativism.. -/- 1.Prescriptive Moral Relativism: “everybody is justified in acting in the way imposed by criteria accepted by the group he belongs to”. Universalism: there are at least (...) some judgments which are valid inter-culturally Absolutism: there are at least some particular prescriptions which are valid without exception everywhere and always -/- 2. The traditional proof of prescriptive moral relativism: the argument from variability: Judgments, rules, and shared values are de facto variable in time and space. The traditional counter-proof: examples of variability do not prove what skeptics contend. -/- 3. Pre-history of the doctrine -Ancient sophists: either immoralist or contractualist -Modern moral scepticism (xvii c.): variability as an historical and ethnographic fact supports a sceptical conclusion more moderate than sheer immoralism. - Voltaire, Kant, Reid counter-attack pointing at a universally shared moral sense - Romantics and idealists stage an even more moderate reformulation: instead of universally shared moral sense they point at the Spirit of a People which is: a)alternative to abstract and universal philosophical systems as far as it is lived ‘culture’; b) indivisible unity with an inner harmony and a source of normative standards; c) dynamic, in so far as it is a manifestation of the Spirit through the becoming of National cultures. -/- 4. The birth of Cultural Relativism and its ethical implications 4.1. The 18th c. doctrine was the noble savage (a non-historical doctrine: state of nature vs. social state) 4.2 Edward Tylor (1832-1817) and ethnocentric historicism Savage moral standards are real enough, but they are far and weaker than ours. 4.3 Boas and Malinowski and an holistic reaction to ethnocentric historicism -/- Franz Boas (1858-1942): a) Development of civilizations is not ruled by technical progress nor does it follow a one-way path; instead there are parallel developments (for ex. Agriculture does not follow stock-raising); b) racial characters have no relevance in development of civilization; c) we are not yet in a position to compare externally identical kinds of behaviour till we have not yet understood beliefs and intentions laying at their roots (for ex.: “From an ethnological point of view murder cannot be considered as a single phenomenon”; d) we should distinguish among different practices which are only superficially similar (fro ex. practices traditionally classified under the label “tabù”); e) there is as a fact just one normative ethic, constant in its contents but varying in its extension; f) the implication is not that we cannot judge behavior by members of other groups; it is only a recommendation of caution. -/- Bronislaw Malinowski (1884-1942): a) against Tylor’s and Frazer’s “magpie” methodology, field-work is required, a culture as a whole should be observed from inside; individual elements are incomprehensible; b) a culture is an organic whole; c) its elements are accounted for by their function (economy), avoiding non-observables (empio-criticism). -/- Ruth Benedict and Melville Herskovitz identify Boas’s approach with “cultural relativism”. Benedict: what is normal and abnormal is to be judged on a culture’s own standards, not on our own (“Anthropology and the Abnormal”). Herskovits: “Boas adumbrates what we have come to call cultural relativism” (The Mind, p. 10); “Judgements are based on experience, and experience is interpreted by each individual in terms of his own enculturation” (Man and his Works). -/- 4. How analytic philosophy understood and misunderstood the discussion 4.1. At the beginning of the 20th c., the new view in ethics was non-cognitivism (emotivist and subjectivist). Eric Westermark combines this view with an old-style ethnographic approach in support of relativity of moralities. Moralities are codes, or systems of emotive ‘disinterested’ reactions selected by evolution on their usefulness in terms of survival value for the society that is the carrier of such systems or codes. The moral relativity thesis: there are cases of disagreement that cannot be settled even after agreement about facts. 4.2 Anti-realists Brandt, Mackie, Gilbert, Harman adopt Westermark’s approach in a more sophisticated version: a) moralities are codes with an overall function and may be appraised only as wholes; b) variability is an argument for moral subjectivism; c) apparent legitimacy of deriving shift from ought is legitimized only within one institution d) morality should not be described but instead made, and existing moralities may be improved. Is it ‘real’ relativism? It is clearly subjectivism (a metaethical thesis). The normative thesis is that there better and worse codes, and survival values is the normative standard. -/- 4.3 Particularists MacIntyre, Sandel, Taylor, Wiggins, McDowell ‘Wittgensteinian’ prospectivist arguments bent to support weak-relativist claims MacIntyre: there is ‘incommensurability’ between different theoretical systems in both science and ethics. No argument is possible through different systems Different traditions may coexist for a long time without being able to bring their conflicts to a rational solution. -/- 4.4 Kantian universalists Baier, Gewirth, Rawls, Apel, Habermas Shared claim: justice concerns the right and is universal in so far as it may be based on minimal assumptions Other virtues are relative to context in so far as they are related to comprehensive views of the good - O’Neill criticism: a) it is an assumption shared by both alignments; b) after an alleged crisis brought about by alleged loss of metaphysical certainties, theories of justice have dropped demanding assumptions and kept universalism, virtue theories have kept demanding assumptions and dropped universalism; c) the opposition of virtue and justice has arisen in an unjustified way. O’Neill’s positive proposal: ‘constructive’ procedures may be adopted both (i) concerning all the range of virtues and (ii) across cultures once we abandon idealization and confine ourselves to abstraction from real-world cases. -/- 4.5 A metaethical relativist and anti-relativist normative ethicists: Bernard Williams Williams: vulgar relativism may be assumed to claim that: a) 'just' means 'just in a given society'; b) 'just in a given society' is to be understood in functionalist sense; c) it is wrong for one society’s members to condemn another society’s values. It is inconsistent since in (c) uses ‘just’ in a non-relative way that has been excluded in (a). William’s positive proposal: i) keep a number of substantive or thick ethical concepts that will be different in space and time; ii) admit that public choices are to be legitimized through recourse to more abstract procedures and relying on more thin ethical concepts. -/- 5. Critical remarks 5.1 The only real relativism available is ‘vulgar’ relativism (Westermark?) 5.2. Descriptive universalism (or absolutism) has a long pedigree, from Cicero on, reaching Boas himself but it is useless as an answer to normative questions 5.3. Twentieth-century philosophical discussion seems to discuss an ad hoc doctrine reconstructed by assembling obsolete philosophical ideas but ignoring the real theory of cultural relativism as formulated by anthropologists. -/- 6. A distinction between ethoi and ethical theories as a way out of confusions a)There are systems of conventions de facto existing. These may be studies from outside as phenomena or facts. b)There is moral argument and this, when studies from outside, is a fact, but this does not influence in any degree the possible validity of claims advanced. c) the difference between the above claims and Mackie’s criticism to Searle’s argument of the promising game is that promises, arguments etc. are also phenomena, but they are also communicative phenomena with a logical and pragmatic structure. -/- 7.Conclusions: a) cultural relativism, as a name for Boas’s methodology is a valuable discovery, and in this sense we are all relativists; b) ethical relativism, as an alleged implication of cultural relativism, has been argued in a philosophically quite unsophisticated way by Benedict and Herskovits; philosophers apparently discussed ethical relativism in the basis of a rather faint impression of what cultural relativism had been. c) a full-fledged ethical relativism has hardly been defended by anybody among philosophers; virtually no modern philosopher really argued a prescriptive version of the thesis; d) we may accept the grain of truth in ethical relativism by including relativist critique to ethical absolutism into a universalist normative doctrine that be careful in separating open-textured formulations of universal claims from culturally conditioned particular prescriptions. -/- .

How were reliable predictions made before Pascal and Fermat's discovery of the mathematics of probability in 1654? What methods in law, science, commerce, philosophy, and logic helped us to get at the truth in cases where certainty was not attainable? The book examines how judges, witch inquisitors, and juries evaluated evidence; how scientists weighed reasons for and against scientific theories; and how merchants counted shipwrecks to determine insurance rates. Also included are the problem of induction before Hume, design arguments (...) for the existence of God, and theories on how to evaluate scientific and historical hypotheses. It is explained how Pascal and Fermat's work on chance arose out of legal thought on aleatory contracts. The book interprets pre-Pascalian unquantified probability in a generally objective Bayesian or logical probabilist sense. (shrink)

Theistic evolutionists often suggest that one can reconcile evolutionary theory with biblical teaching. But in fact Christians have accepted Darwinian theory only after reinterpreting the opening chapters of Genesis. Is such a reinterpretation justified? Within Western Christian thought, there exists a hermeneutical tradition that dates back to St Augustine and which offers guidelines regarding apparent conflicts between biblical teaching and natural philosophy (or “science”). These state that the literal meaning of the text may be abandoned only if the natural-philosophical conclusions (...) are established beyond doubt. But no large-scale scientific theory, such as Darwin’s, can claim this degree of certainty. It follows that to justify their reinterpretation of Genesis 1–3, Christians must either argue that the literal sense of the biblical text can be maintained or accept that the Augustinian view of biblical authority is untenable. Three alternative views are discussed: a first that attempts to limit the scope of biblical authority, a second that distinguishes between the Bible and the Word of God, and a third that abandons the idea that religious faith offers certain knowledge. While the third view seems the most defensible, it comes at a cost: the recognition that, as John Locke put it, “reason must be our last judge and guide in everything.”. (shrink)

Horwich gives a fine analysis of Wittgenstein (W) and is a leading W scholar, but in my view, they all fall short of a full appreciation, as I explain at length in this review and many others. If one does not understand W (and preferably Searle also) then I don't see how one could have more than a superficial understanding of philosophy and of higher order thought and thus of all complex behavior (psychology, sociology, anthropology, history, literature, society). In a (...) nutshell, W demonstrated that when you have shown how a sentence is used in the context of interest, there is nothing more to say. I will start with a few notable quotes and then give what I think are the minimum considerations necessary to understand Wittgenstein, philosophy and human behavior. -/- First one might note that putting “meta” in front of any word should be suspect. W remarked e.g., that metamathematics is mathematics like any other. The notion that we can step outside philosophy (i.e., the descriptive psychology of higher order thought) is itself a profound confusion. Another irritation here (and throughout academic writing for the last 4 decades) is the constant reverse linguistic sexism of “her” and “hers” and “she” or “he/she” etc., where “they” and “theirs” and “them” would do nicely. Likewise, the use of the French word 'repertoire' where the English 'repertory' will do quite well. The major deficiency is the complete failure (though very common) to employ what I see as the hugely powerful and intuitive two systems view of HOT and Searle’s framework which I have outlined above. This is especially poignant in the chapter on meaning p111 et seq. (especially in footnotes 2-7), where we swim in very muddy water without the framework of automated true only S1, propositional dispositional S2, COS etc. One can also get a better view of the inner and the outer by reading e.g., Johnston or Budd (see my reviews). Horwich however makes many incisive comments. I especially liked his summary of the import of W’s anti-theoretical stance on p65. He needs to give more emphasis to ‘On Certainty’, recently the subject of much effort by Daniele Moyal- Sharrock, Coliva and others and summarized in my recent articles. -/- Horwich is first rate and his work well worth the effort. One hopes that he (and everyone) will study Searle and some modern psychology as well as Hutto, Read, Hutchinson, Stern, Moyal-Sharrock, Stroll, Hacker and Baker etc. to attain a broad modern view of behavior. Most of their papers are on academia dot edu and philpapers dot org , but for PMS Hacker see his papers on his Oxford page. -/- He gives one of the most beautiful summaries of where an understanding of Wittgenstein leaves us that I have ever seen. -/- “There must be no attempt to explain our linguistic/conceptual activity (PI 126) as in Frege’s reduction of arithmetic to logic; no attempt to give it epistemological foundations (PI 124) as in meaning based accounts of a priori knowledge; no attempt to characterize idealized forms of it (PI 130) as in sense logics; no attempt to reform it (PI 124, 132) as in Mackie’s error theory or Dummett’s intuitionism; no attempt to streamline it (PI 133) as in Quine’s account of existence; no attempt to make it more consistent (PI 132) as in Tarski’s response to the liar paradoxes; and no attempt to make it more complete (PI 133) as in the settling of questions of personal identity for bizarre hypothetical ‘teleportation’ scenarios.” -/- Finally, let me suggest that with the perspective I have encouraged here, W is at the center of contemporary philosophy and psychology and is not obscure, difficult or irrelevant, but scintillating, profound and crystal clear and that to miss him is to miss one of the greatest intellectual adventures possible. -/- Those wishing a comprehensive up to date framework for human behavior from the modern two systems view may consult my book ‘The Logical Structure of Philosophy, Psychology, Mind and Language in Ludwig Wittgenstein and John Searle’ 2nd ed (2019). Those interested in more of my writings may see ‘Talking Monkeys--Philosophy, Psychology, Science, Religion and Politics on a Doomed Planet--Articles and Reviews 2006-2019 3rd ed (2019), The Logical Structure of Human Behavior (2019), and Suicidal Utopian Delusions in the 21st Century 4th ed (2019) .

My interest is the kind of philosophical vertigo that is a theme of Cavell’s work on scepticism. This describes the anxiety that is elicited via philosophical engagement with certain kinds of sceptical questions. There is a standing puzzle about this notion of vertigo, however, forcefully pressed, for example, by McDowell. Why should a resolution of the sceptical problem, one that putatively completely undercuts the motivation for scepticism in that domain, nonetheless generate vertigo in this sense? I aim to resolve (...) the puzzle, in a way that I believe underwrites this Cavellian notion, via consideration of Wittgenstein’s remarks on the structure of rational evaluation in his final notebooks, published as On Certainty.

There is an important sense in which one can be sure without being certain, i.e., without assigning unit probability. I will offer an explication of this sense of sureness, connecting it with the level of credence that a rational agent would need to have to be confident that she won’t ever lose her confidence. A simple formal result then gives us an explicit formula connecting the threshold α for credence needed for confidence with the threshold needed for being (...) sure: one needs 1−(1−α) to be sure. I then suggest that stepping between α and 1−(1−α) gives a procedure that generates an interesting hierarchy of credential thresholds. (shrink)
