There is a familiar teleological picture of epistemic normativity on which it is grounded in the goal or good of belief, which is taken in turn to be the acquisition of truth and the avoidance of error. This traditional picture has faced numerous challenges, but one of the most interesting of these is an argument that rests on the nearly universally accepted view that this truth goal, as it is known, is at heart two distinct goals that are in tension (...) with one another. This paper will look more closely at the standard way of understanding the truth goal, drawing out both its explicit and implicit features. My aim will be to show that this conception of the truth goal is deeply mistaken, to propose and defend an alternative model, and to show how this alternative model restores the unity of the goal and its potential to ground and explain the normative dimensions of belief.

In this paper it is argued that we have three dispositions, each of which is very laudable in itself: a preference for the positive, constructive and creative aspects of human endeavours; a desire to be open‐minded and tolerant concerning ideas and beliefs; and an admiration of profundity. I have suggested that these dispositions can, if exaggerated or employed uncritically, seduce us into intellectual positions that are very dubious. These arguments are applied to some of the debates within the philosophy of (...) nursing. (shrink)

Susan Haack has always maintained that her unquestionably important foundherentist theory of epistemic justification is not a foundationalism. In a 1997 Synthese exchange, Laurence BonJour questioned her right to this claim, and she dug in and defended it. What was at stake is of timeless importance to epistemology: it goes directly to the question, “What is foundationalism?” I inquire with greater care than either Haack or BonJour took in 1997, and I find decisively in favor of the view that foundherentism (...) is a foundationalism. In the process, I explore the outer limits of foundationalism: I examine just how far a foundationalism can go in allowing the relevance of coherence to epistemic justification. (shrink)

This paper explores the ethical relevance of a precise new characterization of coherence as maximization of satisfaction of positive and negative constraints. A coherence problem can be stated by specifying a set of elements to be accepted or rejected along with sets of positive and negative constraints that incline pairs of elements to be accepted together or rejected together. Computationally tractable and psychologically plausible algorithms are available for determining the acceptance and rejection of elements in a way that reliably approximates (...) coherence maximization. This paper shows how justification of ethical principles and particular judgments can be accomplished by taking into account deductive, explanatory, analogical, and deliberative coherence. (shrink)

This paper provides a computational characterization of coherence that applies to a wide range of philosophical problems and psychological phenomena. Maximizing coherence is a matter of maximizing satisfaction of a set of positive and negative constraints. After comparing five algorithms for maximizing coherence, we show how our characterization of coherence overcomes traditional philosophical objections about circularity and truth.

Paul Boghossian and Hilary Putnam have presented arguments designed to show self-referential difficulties within Rorty’s pragmatism. I respond to these arguments by drawing out the details of the pragmatic account of justification implicit within Rorty’s writings, thereby revealing it to be a sophisticated form of relativism that does not undermine itself. In Section I and II, I motivate my strategy of attributing a positive position to Rorty in order to respond to detailed, analytical arguments such as those of Boghossian, and (...) present an outline of this position, agreeing with Rorty’s critics that it can be justifiably classified as a form of relativism. Sections III to V concern the detail of Boghossian’s argument, in which I show that Boghossian’s contention that Rorty’s rejection of all absolute justification is inconsistent can be satisfactorily answered by explaining the differences between “epistemic systems” in terms of the different purposes they serve. Then in Sections VI to VIII, I further develop Rorty’s account of justification in order to answer Putnam’s charge that Rorty tries to say “from a God’s-Eye View there is no God’s-Eye View.” I reject Rorty’s own “social-reformer” response to this argument, but show that it can be satisfactorily answered by distinguishing two integrated components within Rorty’s pragmatism, one holistic and coherentist, and the other causal and social-evolutionary.

The author uses a series of potential counterexamples to argue against attempts by Bergmann and Plantinga to articulate a distinction between malignant and benign epistemic circularity and, more radically, to argue that epistemic circularity per se is no fallacy, and the concept of epistemic circularity plays no role in the explanation of why some instances of epistemic circularity are irrational. The author contrasts an inferential framework, in which circularity is a problem, with an equilibrium framework, in which the concept of (...) circularity plays no useful role and argues that defeasible reasoning can only be understood in an equilibrium, not an inferential, framework. The author uses an example of reasoning about the reliability of one’s own memory to explain how seemingly malignant epistemic circularity can be rational in an equilibrium framework. The author discusses the relevance of this conclusion to two contemporary issues: the cogency of Plantinga’s Evolutionary Argument against Naturalism and the evolutionary naturalists’ challenges to non-naturalist moral realism—and, indeed, to all forms of non-naturalist normative realism.

According to metaphysical coherentism, grounding relations form an interconnected system in which things ground each other and nothing is ungrounded. This potentially viable view’s logical territory remains largely unexplored. In this paper, I describe that territory by articulating four varieties of metaphysical coherentism. I do not argue for any variety in particular. Rather, I aim to show that not all issues which might be raised against coherentism will be equally problematic for all the versions of that view, which features far (...) more nuance and diversity than is typically ascribed to it.

Abstract Epistemic infinitism is certainly not a majority view in contemporary epistemology. While there are some examples of infinitism in the history of philosophy, more work needs to be done mining this history in order to provide a richer understanding of how infinitism might be formulated internal to different philosophical frameworks. Accordingly, we argue that the philosophy of Emmanuel Levinas can be read as operating according to an ?impure? model of epistemic infinitism. The infinite obligation inaugurated by the ?face to (...) face encounter? with the Other yields an approach to the ethics of belief that accords with infinitism. This reading of Levinas brings his ethical thought into dialogue with contemporary epistemology as well as provides an historical example of infinitism within the current debates. (shrink)

[Significantly updated in Chapter 7 of Awareness and the Substructure of Knowledge] Many have found it plausible that knowledge is a constitutively normative state, i.e. a state that is grounded in the possession of reasons. Many have also found it plausible that certain cases of proprioceptive knowledge, memorial knowledge, and self-evident knowledge are cases of knowledge that are not grounded in the possession of reasons. I refer to these as cases of basic knowledge. The existence of basic knowledge forms a (...) primary objection to the idea that knowledge is a constitutively normative state. In what follows I offer a way through the apparent dilemma of having to choose between either basic knowledge or the normativity of knowledge. The solution involves homing in on a state of awareness (≈non-accidental true representation) that is distinct from knowledge and which in turn grounds the normativity of knowledge in a way that is fully consistent with the existence of basic knowledge. An upshot of this is that externalist theories of knowledge turn out to be fully compatible with the thesis that knowledgeable beliefs are always beliefs that are justified by the reasons one possesses.

The paper seeks to answer two new questions about truth and scientific change: What lessons does the phenomenon of scientific change teach us about the nature of truth? What light do recent developments in the theory of truth, incorporating these lessons, throw on problems arising from the prevalence of scientific change, specifically, the problem of pessimistic meta-induction?

The article investigates and defends central elements of Quine’s naturalized epistemology. Davidson’s coherentist attacks on Quine’s empiricismare dismissed. The view is advocated that sensory experience plays an essential epistemic role, and that, therefore, the study of perception must be taken seriously in the theory of knowledge. The author rejects, however, Quine’s behavioristic conception of experience as stimulation of sensory receptors and instead argues for a richer conception, according to which an experience is a sensory state of things appearing in certain (...) ways to us. Finally, it is shown that this standpoint allows us to acknowledge a given element in experience without falling victim to a myth. (shrink)

The author argues that coherence views of justification, in spite of their crucial insight into the interpenetration of our beliefs, neglect a key constraint on justification: they are unable to accommodate the epistemic significance of experience. Epistemic justification is not just a function of our beliefs and their interrelations. Both, beliefs and experiences, are relevant to the justification of an empirical belief. Experience is not itself a form of belief or disposition to believe; it cannot be analyzed in doxastic terms. (...) And, yet, nondoxastic experiences play a justificatory role, not merely a causal role. The positive epistemic status of a perceptual belief depends upon being appeared to in appropriate ways. It is important that, for an ordinary perceptual belief to be justified, one does not have to believe that one is appeared to in these ways. It is the experiences themselves, the ways of being appeared to, not our beliefs about them, that are required for justification. (shrink)

Design has usually been linked to art and applied in scenarios related to everyday life. Even when design has, on occasion, made its way into the world of academia, it has always been closely linked to art and scenarios related everyday life. At last, however, the idea of design has reached the field of epistemology: an area within the very heart of philosophy that has always focused, in theory, on the foundations of knowledge. Consequently, design is being studied from different (...) approaches interested in the foundation of knowledge, theoretical and practical. This is one of the reasons why abduction and pragmatism have been considered relevant from a design perspective. This paper first shows the main features of abduction and pragmatism, describes their evolution and considers their mutual implications. Second, the epistemology of design is analysed considering its most relevant characteristics. Third, the connection between abduction and, on the one hand, pragmatism and, on the other, design epistemology is addressed. Finally, the role of abductive inference in grounding a real epistemology for design theory from the naturalised cognitive perspective of abduction is outlined. The central proposition is that this approach is essential as a methodological innovation, as it allows us to analyse both the inquiry process and the design process as interdependent when dealing with practical problems of a social and cultural nature. This approach allows us to analyse how human actions determine changes in the theoretical framework from which we make our inquiry. In short, the world is an open-ended project that humans design through our daily inquiry. (shrink)

RESUMO A percepção, o modo pelo qual sentimos o mundo, é comumente distinta da cognição, o modo pelo qual o pensamos. Entretanto, a percepção parece exercer um papel importante na justificação de crenças empíricas, ainda que haja divergência a respeito de como isso ocorre. A hipótese da penetrabilidade cognitiva da percepção problematiza ambas essas afirmações. Segundo essa teoria, estados cognitivos anteriores podem afetar a etiologia do conteúdo sensório da experiência, gerando, como efeito, uma espécie de insensibilidade aos estímulos externos. Como (...) resultado, lançam-se suspeitas quanto à isenção do “tribunal” da experiência. Este artigo tem o propósito de discutir casos de má penetrabilidade cognitiva como consequências de vícios intelectuais. Vícios intelectuais são traços de caráter, como dogmatismo e preconceito, que impedem o exercício apto e responsável da inquirição e outras práticas epistêmicas. Essa abordagem tem a dupla vantagem de, por um lado, elucidar esse “comércio ilegal” entre percepção e cognição, e por outro, responder ao problema da circularidade epistêmica, causado pela penetrabilidade cognitiva da percepção. ABSTRACT Perception, the way we experience the world, is often distinguished from cognition, the way we think about the world. However, even though there is no agreement about how it happens, perception seems to have an important role in the justification of empirical beliefs. The hypothesis of cognitive penetration ofperception contradicts such claims. According to such hypothesis, early cognitive states can affect the etiology of the contents of sensory experience, yielding a kind of insensibility to external stimuli. This casts doubts on impartiality of the “tribunal” of sense experience. The aim of this article is to discuss cases of bad cognitive penetrability which result from intellectual vices. Intellectual vices are character traits, such as dogmatism and prejudice, which prevent the apt and responsible exercise of inquiry and others epistemicpractices. This approach has two advantages: first, it elucidates “illegal trades” between perception and cognition, and second, it answers the problem of epistemic circularity, posed by the cognitive penetrability of perception.

I argue that coherence is truth-conducive in that coherence implies an increase in the probability of truth. Central to my argument is a certain principle for transitivity in probabilistic support. I then address a question concerning the truth-conduciveness of coherence as it relates to (something else I argue for) the truth-conduciveness of consistency, and consider how the truth-conduciveness of coherence bears on coherentist theories of justification.

Following Quine, Davidson, and Dennett, I take mental states and linguistic meaning to be individuated with reference to interpretation. The regulative principle of ideal interpretation is to maximize rationality, and this accounts for the distinctiveness and autonomy of the vocabulary of agency. This rationality-maxim can accommodate empirical cognitive-psychological investigation into the nature and limitations of human mental processing. Interpretivism is explicitly anti-reductionist, but in the context of Rorty's neo-pragmatism provides a naturalized view of agents. The interpretivist strategy affords a less (...) despondent view of constructive philosophical activity than Rorty's own. (shrink)

This article surveys work in epistemology since the mid-1980s. It focuses on contextualism about knowledge attributions, modest forms of foundationalism, and the internalism/externalism debate and its connections to the ethics of belief.

This paper exposits and makes steps towards solving a puzzle about epistemic value. The puzzle is that several principles about the epistemic value of true beliefs and epistemic disvalue of false beliefs are, individually, plausible but, collectively, contradictory. My solution claims that sometimes false beliefs are epistemically valuable. I nonetheless show how my solution is not in deep tension with the Jamesian idea that true beliefs are epistemically valuable and false beliefs are epistemically disvaluable. I conclude by indicating how the (...) results here are relevant to formulating and defending Veritism. (shrink)

This paper examines some of the most important metaphors and analogies that epistemologists have used to discuss the structure and validity of knowledge. After reviewing foundational, coherentist, and other metaphors for knowledge, we discuss the metaphilosophical significance of the prevalence of such metaphors. We argue that they support a view of philosophy as akin to science rather than poetry or rhetoric. Keywords: epistemology, metaphor, analogy, metaphilosophy, foundations, coherence.

This paper evaluates attempts to defend established concepts of expertise and clinical judgement against the incursions of evidence‐based practice. Two related arguments are considered. The first suggests that standard accounts of evidence‐based practice imply an overly narrow view of ‘evidence’, and that a more inclusive concept, incorporating ‘patterns of knowing’ not recognised by the familiar evidence hierarchies, should be adopted. The second suggests that statistical generalisations cannot be applied non‐problematically to individual patients in specific contexts, and points out that this (...) is why we need clinical judgement. In evaluating the first argument, I propose a criterion for what counts as evidence. It is a minimalist criterion but the ‘patterns of knowing’, referred to in the literature, still fail to meet it. In evaluating the second argument, I will outline the powerful empirical reasons we have for thinking that decisions based on research evidence are usually better than decisions based on clinical judgement; and show that current efforts to rehabilitate clinical judgement seriously underestimate the strength of these reasons. By way of conclusion, I will sketch the ways in which the concept of expertise will have to be modified if we accept evidence‐based practice as a template for health‐care. (shrink)

Psychological research has shown that cognitive illusions, of which visual illusions are just a special case, are systematic and pervasive, raising epistemological questions about how error in all forms of research can be identified and eliminated. The quantitative sciences make use of statistical techniques for this purpose, but it is not clear what the qualitative equivalent is, particularly in view of widespread scepticism about validity and objectivity. I argue that, in the light of cognitive psychology, the ‘error question’ cannot be (...) dismissed as a positivist obsession, and that the concepts of truth and objectivity are unavoidable. However, they constitute only a ‘minimal realism’, which does not necessarily bring a commitment to ‘absolute’ truth, certainty, correspondence, causation, reductionism, or universal laws in its wake. The assumption that it does reflects a misreading of positivism and, ironically, precipitates a ‘crisis of legitimation and representation’, as described by constructivist authors. (shrink)

Interest in the Keynesian concept of evidential weight has led to divergent views concerning the burden of proof in adjudication. It is argued that Keynes's concept is properly engaged only in the context of one special kind of decision, the decision whether or not the evidence is ripe for a decision on the underlying merits, whether the latter decision is based on probability, relative plausibility, coherence or otherwise. As a general matter, this question of ripeness is appropriately assigned to the (...) judiciary for resolution as part of the burden of production, rather than to the jury or other factfinder as part of the burden of persuasion.

“The day the Enlightenment went out”, is how Gary Wills described the re-election of President George W. Bush in an op-ed column in the New York Times (November 4, 2004). Reflecting upon the conservative religious vote that put Bush back in the White House, Wills wondered if there was any connection between the fact that many more Americans believe in the Virgin Birth than in Darwin’s theory of evolution and that 75 percent of Bush supporters actually believed—without an iota of (...) credible evidence— that Iraq was directly responsible for the terrorist attack on 9/11. Wills asks if a people that have lost respect for evidence and critical reasoning can still be called an enlightened nation. “Belief that does not require proof or evidence” is how the Webster New World Dictionary defines the word “faith”. It also defines “faith” as “faith in God”. The American elections, then, turned out to be a massive faith-based initiative in both these senses of the word. Belief and policies backed not by evidence, but by religious values wedded to an aggressive nationalism are driving American politics. In this America is not alone. India, the subject matter of much of what follows, has had its own brush with faith-driven politics in which an aggressive Hindu nationalism came to color public policies, including science education.1 The question is: how do secular democracies like the United States and India (the world’s first and the world’s largest democracies, respectively), manage to square off their official commitment to enlightened values of openness and religion–state separation with the realities of faith-based politics? How do matters of fact—that is, questions that in principle can be decided by empirical evidence—end up getting decided on the basis of religious faith. This alchemy of turning secular matters of fact into religiouscivilizational matters holds the key to understanding the democratic-populist route to religious fundamentalism.. (shrink)

The innovation systems approach has swiftly spread out worldwide in the last three decades and stood as an important framework for policy-making in the fields of science, technology, and innovation. At the same time, there have been serious and untreated concerns in the literature about the theoretical soundness of this approach. Our discussion in this paper is based on the belief that a detailed analysis on epistemological foundations of the approach could shed a judgmental light on the aforementioned concerns. To (...) provide that analysis, we reconstructed and studied the nature and evolution of innovation systems approach as a case of conceptual revolution against the more established traditions in economics of innovation. Our analyses show that the rise of the systemic view of innovation include radical changes in conceptual structures pertaining to orthodox view of innovation. These developments also go so far as to include significant shifts in epistemological foundations of the old paradigm. These later shifts provide us with an epistemological base from which we can shelter the innovation systems approach from the hard criticisms rooted in a quasi-positivist point of view. That epistemological base also shows the path for the future development of the approach towards more robustness and precision. (shrink)

This is a very selective survey of developments in epistemology, concentrating on work from the past twenty years that is of interest to philosophers of science. The selection is organized around interesting connections between distinct themes. I first connect issues about skepticism to issues about the reliability of belief-acquiring processes. Next I connect discussions of the defeasibility of reasons for belief to accounts of the theory-independence of evidence. Then I connect doubts about Bayesian epistemology to issues about the content of (...) perception. The last detailed connection is between considerations of the finiteness of cognition and epistemic virtues. To connect the connections I end by briefly discussing the pressure that consideration of social roles in the transmission of belief puts on the purposes of epistemology. (shrink)

It is well known that the process of scientific inquiry, according to Peirce, is drivenby three types of inference, namely abduction, deduction, and induction. What isbehind these labels is, however, not so clear. In particular, the common identificationof abduction with Inference to the Best Explanation (IBE) begs the question,since IBE appears to be covered by Peirce's concept of induction, not that of abduction.Consequently, abduction ought to be distinguished from IBE, at least on Peirce's account. The main aim of the paper, (...) however, is to show that this distinction is most relevant with respect to current problems in philosophy of science and epistemology (like attempts to supply suitable notions of realism and truth as well as related concepts like coherence and unification). In particular, I also try to show that (and in what way) Peirce's inferential triad can function as a method that ensures both coherence and correspondence. It is in this respect that his careful distinction between abduction and induction (or IBE) ought to be heeded. (shrink)

The article is an attempt to better understand the objections to the doctrine of 'reliabilism' made by prominent epistemologists. The view argued for here is that while one extreme case of anti-reliabilism seems to be the paradigm case against the entire concept, this very case points out some additional, and implicit, problems with the standard account of epistemic justification. The most notable is that the standard view attacks reliabilism on the grounds that it lacks a means of giving adequate reasons (...) or evidence for its claims. We argue that the standard view, while correct on its paradigm case against reliabilism, is itself weakened by its lack of recognition of the central role theories of evidence must play in its basic account. Since theories of evidence are themselves divergent and problematic in terms of explaining how claims are justified, the standard account needs to address the issues of which account of evidence is 'adequate' and why it is. It is finally suggested that traditional epistemology might be more accurately described as a branch of confirmation theory. (shrink)

The article argues for the possibility of translation manuals having an implicit internal structure. This structure is composed of specific methodological assumptions and techniques. Using the (N)-type and (G)-type distinction developed by Fuller for the study of scientific behavior, it is shown that these are incomplete characterizations of translation manuals. A more complete characterization must involve an analysis of how the presence or absence of methodological rules influences the interpretation of specific research questions. It is further argued that while Quine's (...) original indeterminacy thesis cannot be completely rejected, in some cases it can be modified to reflect the importance of the methodological constraints. Finally, it is suggested that the more critical analysis of translation manuals will benefit the on-going debates in the study of scientific behavior. (shrink)

The phenomenon of mutual support presents a specific challenge to the foundationalist epistemologist: Is it possible to model mutual support accurately without using circles of evidential support? We argue that the appearance of loops of support arises from a failure to distinguish different synchronic lines of evidential force. The ban on loops should be clarified to exclude loops within any such line, and basing should be understood as taking place within lines of evidence. Uncertain propositions involved in mutual support relations (...) are conduits to each other of independent evidence originating ultimately in the foundations. We examine several putative examples of benign loops of support and show that, given the distinctions noted, they can be accurately modeled in a foundationalist fashion. We define an evidential "tangle," a relation among three propositions that appears to require a loop for modeling, and prove that all such tangles are trivial in a sense that precludes modeling them with an evidential circle.

The article remarks that, despite what many relativists claim, realism still is an arguable and defendable position. Realism is for sure quite an unpopular stance today, but the standard arguments against it are by no means conclusive. If one asks what difference is made to our knowledge claims if we accept the existence of an extra-conceptual world, the answer is the following: such recognition is likely to undermine the largely diffused anthropocentric stance which identifies reality with our knowledge of it.

What role does language play in the process of building worldviews? To address this question, in the first section of this paper we will clarify what we mean by worldviews and how they differ, in our perspective, from cosmovisions. In a nutshell, we define worldviews as the biological interpretations agents create of the world around them and cosmovision the more general cultural-based reflections on it. After presenting our definition for worldview, we will also present the multi-shaped viewpoint that frames our (...) analysis, adopting three concepts that can help us explain how agents construct and develop their worldviews: saliences, pregnances, and abduction. While the notions of saliences and pregnances will explain how agents recognize anomalies in their worldview, the concept of abduction will help us discuss how they can learn to approach, explain, and use these anomalies to get new skills and abilities. This other point will lead us to discuss the role of language in this process, which will be describe as an artifact that permits the agent to use abduction to “normalize” and exploit anomalies, being now the ultimate artifact to build, develop, and update their worldviews.

The New Evil Demon Problem is supposed to show that straightforward versions of reliabilism are false: reliability is not necessary for justification after all. I argue that it does no such thing. The reliabilist can count a number of beliefs as justified even in demon worlds, others as unjustified but having positive epistemic status nonetheless. The remaining beliefs---primarily perceptual beliefs---are not, on further reflection, intuitively justified after all. The reliabilist is right to count these beliefs as unjustified in demon worlds, (...) and it is a challenge for the internalist to be able to do so as well. (shrink)

The Sellarsian dilemma is a famous argument that attempts to show that nondoxastic experiential states cannot confer justification on basic beliefs. The usual conclusion of the Sellarsian dilemma is a coherentist epistemology, and the usual response to the dilemma is to find it quite unconvincing. By distinguishing between two importantly different justification relations (evidential and nonevidential), I hope to show that the Sellarsian dilemma, or something like it, does offer a powerful argument against standard nondoxastic foundationalist theories. But this reconceived (...) version of the argument does not support coherentism. Instead, I use it to argue for a strongly externalist epistemology. (shrink)

Unlike natural agents, artificial agents are, to varying extent, designed according to sets of principles or assumptions. We argue that the designer’s philosophical position on truth, belief and knowledge has far reaching implications for the design and performance of the resulting agents. Of the many sources of design information and background we believe philosophical theories are under-rated as valuable influences on the design process. To explore this idea we have implemented some computer-based agents with their control algorithms inspired by two (...) strongly contrasting philosophical positions. A series of experiments on these agents shows that, despite having common tasks and goals, the behaviour of the agents is markedly different and this can be attributed to their individual approaches to belief and knowledge. We discuss these findings and their support for the view that epistemological theories have a particular relevance for artificial agent design. (shrink)

The aim of this paper is to argue that doxastic responsibility, i.e., responsibility for holding a certain doxastic attitude, is not based on direct doxastic control. There are two different kinds of direct doxastic control to be found in the literature, intentional doxastic control and evaluative doxastic control. Although many epistemologists agree that we do not have intentional doxastic control over our doxastic attitudes, it has been argued that we have evaluative doxastic control over the majority of our doxastic attitudes. (...) This has led to the assumption that doxastic responsibility is based on evaluative doxastic control. In the first part of this paper I will introduce the notion of doxastic responsibility and the framework of doxastic guidance control as well as the approaches to direct and indirect doxastic control. I will then argue that doxastic responsibility is not based on direct doxastic control by showing that doxastic responsibility is neither based on intentional nor on evaluative doxastic control.

The paper discusses Bernard Bolzano’s epistemological approach to believing and knowing with regard to the epistemic requirements of an axiomatic model of science. It relates Bolzano’s notions of believing, knowing and evaluation to notions of infallibility, immediacy and foundational truth. If axiomatic systems require their foundational truths to be infallibly known, this knowledge involves both evaluation of the infallibility of the asserted truth and evaluation of its being foundational. The twofold attempt to examine one’s assertions and to do so by (...) searching for the objective grounds of the truths asserted lies at the heart of Bolzano’s notion of knowledge. However, the explanatory task of searching for grounds requires methods that cannot warrant infallibility. Hence, its constitutive role in a conception of knowledge seems to imply the fallibility of such knowledge. I argue that the explanatory task contained in Bolzanian knowing involves a high degree of epistemic virtues, and that it is only through some salient virtue that the credit of infallibility can distinguish Bolzanian knowing from a high degree of Bolzanian believing.
