As an introduction to explicating the concept of basic knowledge, I shall examine Aristotle's argument for the existence of basic knowledge and urge two basic points. The first point is that Aristotle's argument, properly viewed, establishes the existence of a kind of knowledge, basic or non-demonstrative knowledge, the definition of which does not require the specification of, and hence the satisfaction of,anyevidence condition. This point has been urged by philosophers like Peirce and Austin but it needs further argumentation because most (...) analytic epistemologists still insist thatallknowledge, whether basic or non-basic, requires the satisfaction of some evidence condition. Secondly, to urge that the basic propositions whose existence is established by Aristotle's argument could be privileged but not known, for the reason that there is no evidence condition for them, would be to adopt a position that either entails wholesale skepticism or undermines the basic distinction between knowledge and belief.

Conductive Arguments are held to be defeasible, non-conclusive, and neither inductive nor deductive (Blair and Johnson in Conductive argument: An overlooked type of defeasible reasoning. College, London, 2011). Of the different kinds of Conductive Arguments, I am concerned only with those for which it is claimed that countervailing considerations detract from the support for the conclusion, complimentary to the positive reasons increasing that support. Here’s an example from Wellman (Challenge and response: justification in ethics. Southern Illinois University Press, Chicago, 1971): (...) Although your lawn needs cutting, you ought to take your son to the movies because the picture is ideal for children and will be gone by tomorrow. (1971: 57) I argue that Conductive Arguments are not possible—the “ought” conclusion only holds if countervailing considerations are nullified. (shrink)

In a recent paper, Tristan Haze offers two examples that, he claims, are counterexamples to Nozick's Theory of Knowledge. Haze claims his examples work against Nozick's theory understood as relativized to belief forming methods M. We believe that they fail to be counterexamples to Nozick's theory. Since he aims the examples at tracking theories generally, we will also explain why they are not counterexamples to Dretske's Conclusive Reasons Theory of Knowledge.

Tracking theories of knowledge are widely known to have the consequence that knowledge is not closed. Recent arguments by Vogel and Hawthorne claim both that there are no legitimate examples of knowledge without closure and that the costs of theories that deny closure are too great. This paper considers the tracking theories of Dretske and Nozick and the arguments by Vogel and Hawthorne. We reject the arguments of Vogel and Hawthorne and evaluate the costs of closure denial for tracking theories (...) of knowledge. (shrink)

Much of contemporary epistemology proceeds on the assumption that tracking theories of knowledge, such as those of Dretske and Nozick, are dead. The word on the street is that Kripke and others killed these theories with their counterexamples, and that epistemology must move in a new direction as a result. In this paper we defend the tracking theories against purportedly deadly objections. We detect life in the tracking theories, despite what we perceive to be a premature burial.

ABSTRACT Drawing inspiration from Fred Dretske, L. S. Carrier, John A. Barker, and Robert Nozick, we develop a tracking analysis of knowing according to which a true belief constitutes knowledge if and only if it is based on reasons that are sensitive to the fact that makes it true, that is, reasons that wouldn’t obtain if the belief weren’t true. We show that our sensitivity analysis handles numerous Gettier-type cases and lottery problems, blocks pathways leading to skepticism, and validates the (...) epistemic closure thesis that correct inferences from known premises yield knowledge of the conclusions. We discuss the plausible views of Ted Warfield and Branden Fitelson regarding cases of knowledge acquired via inference from false premises, and we show how our sensitivity analysis can account for such cases. We present arguments designed to discredit putative counterexamples to sensitivity analyses recently proffered by Tristan Haze, John Williams and Neil Sinhababu, which involve true statements made by untrustworthy informants and strange clocks that sometimes display the correct time while running backwards. Finally, we show that in virtue of employing the paradox-free subjunctive conditionals codified by Relevance Logic theorists instead of the paradox-laden subjunctive conditionals codified by Robert Stalnaker and David Lewis.

Abstract: Luciano Floridi has impressively applied the concept of information to problems in semantics and epistemology, among other areas. In this essay, I briefly review two areas where I think one may usefully raise questions about some of Floridi's conclusions. One area is in the project to naturalize semantics and Floridi's use of the derived versus nonderived notion of semantic content. The other area is in the logic of information and knowledge and whether knowledge based on information necessarily supports closure, (...) in every instance. I suggest that it does not and, thereby, raise a challenge to Floridi's logic of being informed. (shrink)

This article examines the intersection of the theory of extended mind/cognition and theory of knowledge. In the minds of some, it matters to conditions for knowing whether the mind extends beyond the boundaries of body and brain. I examine these intuitions and find no support for this view from tracking theories of knowledge. I then argue that the apparent difference extended mind is supposed to have for ability or credit theories is also illusory.

In a recent very interesting and important challenge to tracking theories of knowledge, Williams & Sinhababu claim to have devised a counter-example to tracking theories of knowledge of a sort that escapes the defense of those theories by Adams & Clarke. In this paper we will explain why this is not true. Tracking theories are not undermined by the example of the backward clock, as interesting as the case is.

Theories of epistemically justified belief have long assumed individualism. In its extreme, or Lockean, form individualism rules out justified belief on testimony by insisting that a subject is justified in believing a proposition only if he or she possesses first-hand justification for it. The skeptical consequences of extreme individualism have led many to adopt a milder version, attributable to Hume, on which a subject is justified in believing a proposition only if he or she is justified in believing that there (...) is testimony in favor of the proposition deriving from a reliable source. I argue that this Humean individualism also leads to skepticism in a wide range of cases; it makes it impossible for a layperson to be justified on expert testimony. In addition, I argue that the apparent motivation for the Humean view, an insistence on intellectual autonomy in justification, does not succeed in motivating it. I then explore the contours of a collectivist view of justification on testimony, with special attention to the place of a subject's intellectual autonomy in such justification. I try to bring empirical results of the psychology of persuasion to bear on the epistemological issues. (shrink)

I argue against the Standard View of ignorance, according to which ignorance is defined as equivalent to lack of knowledge, that cases of environmental epistemic luck, though entailing lack of knowledge, do not necessarily entail ignorance. In support of my argument, I contend that in cases of environmental luck an agent retains what I call epistemic access to the relevant fact by successfully exercising her epistemic agency and that ignorance and non-ignorance, contrary to what the Standard View predicts, are not (...) modal in the sense that knowledge is. After responding to objections, I conclude by sketching an alternative account of ignorance centered on the notions of epistemic access and epistemic agency. (shrink)

It is often said that belief aims at truth. I argue that if belief has an aim then that aim is knowledge rather than merely truth. My main argument appeals to the impossibility of forming a belief on the basis of evidence that only weakly favours a proposition. This phenomenon, I argue, is a problem for the truth-aim hypothesis. By contrast, it can be given a simple and satisfying explanation on the knowledge-aim hypothesis. Furthermore, the knowledge-aim hypothesis suggests a very (...) plausible account of what it takes for evidence to be sufficiently good to make belief possible. I offer several further considerations in favour of the knowledge-aim hypothesis, and deal with objections. Although the main point of the paper is not to defend the view that belief has an aim, but to adjudicate between accounts of what that aim is, my argument nevertheless requires some attention to the motivation for attributing an aim to belief in the first place. In particular, I will explain an important advantage that this view has over the view that belief is not aim-directed, but only subject to a constitutive norm. (shrink)

Wem wird geglaubt und wem nicht? Wessen Wissen wird weitergegeben und wessen nicht? Wer hat eine Stimme und wer nicht? Theorien der epistemischen Ungerechtigkeit befassen sich mit dem breiten Feld der ungerechten oder unfairen Behandlung, die mit Fragen des Wissens, Verstehens und Kommunizierens zusammenhängen, wie z.B. die Möglichkeit, vom Wissen oder von kommunikativen Praktiken ausgeschlossen zu werden oder zum Schweigen gebracht zu werden, aber auch Kontexte, in denen die Bedeutungen mancher systematisch verzerrt oder falsch gehört und falsch dargestellt werden, in (...) denen manchen misstraut wird oder es an epistemischer Handlungsfähigkeit mangelt. In diesem Buch wird eine Übersicht über die breite Debatte epistemischer Ungerechtigkeit, epistemischer Unterdrückung und epistemischer Gewalt gegeben, in dem unterschiedliche Theorien, die sich auf der Schnittstelle von Gerechtigkeitstheorie und epistemischen Fragen befinden, systematisch und kritisch diskutiert sowie theoretische Vorgänger dieser Theorien beleuchtet werden.

Single-premise epistemic closure is the principle that: if one is in an evidential position to know that P where P entails Q, then one is in an evidential position to know that Q. In this paper, I defend the viability of opposition to closure. A key task for such an opponent is to precisely formulate a restricted closure principle that remains true to the motivations for abandoning unrestricted closure but does not endorse particularly egregious instances of closure violation. I focus (...) on two brands of epistemic theory that naturally incorporate closure restrictions. The first type holds that the truth value of a knowledge ascription is relative to a relevant question. The second holds that the truth value of a knowledge ascription is relative to a relevant topic. For each approach, I offer a formalization of a leading theory from the literature and use this formalization to evaluate the theory’s adequacy in terms of a precise set of desiderata. I conclude that neither theory succeeds in meeting these desiderata, casting doubt on the viability of the underlying approaches. Finally, I offer a novel variant of the topic-sensitive approach that fares better. (shrink)

Social knowledge, for the most part, is knowledge through testimony. This essay is an overview of the epistemology of testimony. The essay separates knowledge from justification, characterizes testimony as a source of belief, explains why testimony is a source of knowledge, canvasses arguments for anti-reductionism and for reductionism in the reductionism vs. anti-reductionism debate, addresses counterexamples to knowledge transmission, defends a safe basis account of testimonial knowledge, and turns to social norms as a partial explanation for the reliability of testimony.

A ‘lottery belief’ is a belief that a particular ticket has lost a large, fair lottery, based on nothing more than the odds against it winning. The lottery paradox brings out a tension between the idea that lottery beliefs are justified and the idea that that one can always justifiably believe the deductive consequences of things that one justifiably believes – what is sometimes called the principle of closure. Many philosophers have treated the lottery paradox as an argument against the (...) second idea – but I make a case here that it is the first idea that should be given up. As I shall show, there are a number of independent arguments for denying that lottery beliefs are justified. (shrink)

In order to perform certain actions – such as incarcerating a person or revoking parental rights – the state must establish certain facts to a particular standard of proof. These standards – such as preponderance of evidence and beyond reasonable doubt – are often interpreted as likelihoods or epistemic confidences. Many theorists construe them numerically; beyond reasonable doubt, for example, is often construed as 90 to 95% confidence in the guilt of the defendant. -/- A family of influential cases suggests (...) standards of proof should not be interpreted numerically. These ‘proof paradoxes’ illustrate that purely statistical evidence can warrant high credence in a disputed fact without satisfying the relevant legal standard. In this essay I evaluate three influential attempts to explain why merely statistical evidence cannot satisfy legal standards. (shrink)

This article develops and defends a full account of the nature and normativity of resistance to evidence, according to which resistance to evidence is an instance of input-level epistemic malfunctioning. At the core of this epistemic normative picture lies the notion of knowledge indicators, as evidential probability increasing facts that one is in a position to know; resistance to evidence is construed as a failure to uptake knowledge indicators.

Our folk epistemology says that if someone knows that P and tells you that P, then, given the absence of defeaters, if you believe what they tell you, you will come to know that P as well. A speaker's knowledge that P is then, for the most part, enough for a hearer to come to know that P. But there are counterexamples to this principle: testimonial knowledge does not always transfer from the speaker to the hearer. Why should that be (...) so? Because testimonial knowledge arises through the flow of information--from conclusive grounds--from the speaker through the speaker's assertion to the hearer's state of comprehension as of the speaker's assertion. A speaker's belief can be based on conclusive grounds, but the speaker's assertion may fail to provide conclusive grounds to the hearer. Then the hearer won't acquire knowledge, even from a knowledgeable speaker. Knowledge from testimony then works more like knowledge through perception. But wait, you say, that can't be so because testimony involves free will but perception does not. The essay ends with a broadly Hume inspired reply to this objection. (shrink)

Dogmatism is sometimes thought to be incompatible with Bayesian models of rational learning. I show that the best model for updating imprecise credences is compatible with dogmatism.

In Bias: A Philosophical Study, Thomas Kelly offers a response to epistemological skepticism grounded in his account of bias. According to Kelly, the classic argument for skepticism is best understood as an attempt to show that our commonsense beliefs are biased against the skeptic. Kelly grants that this is true but argues that biased beliefs can still be knowledge. I offer two objections. First, if we are applying Kelly’s theory of bias to skepticism, it is best to think of the (...) skeptic’s challenge to be that our anti-skeptical beliefs are based on what we know to be biased reasons. Kelly has not shown that this sort of bias is compatible with knowledge. Second, Kelly’s approach to the problem of skepticism is an example of what I have called “unambitious epistemology.” And, for that reason, it is not a satisfactory answer to skepticism. (shrink)

After providing some historical and systematic background, I introduce the structure of a very natural and influential sceptical underdetermination argument. The argument assumes that it is metaphysically possible for a deceived subject to have the same evidence that a non-deceived subject has, and tries to draw consequences about justification from that assumption of metaphysical possibility. I first variously object to the transition from the assumption to its supposed consequences. In the central part of the paper, I then critically consider some (...) influential ways of bridging the gap between the assumption and its supposed consequences, which generally consist in strengthening the assumption from one of metaphysical possibility into one of either counterfactual implication or entailment. The discussion indicates that epistemic facts are much more independent from metaphysically modal facts than the sceptical underdetermination argument requires. (shrink)

Knowledge is closed under implication, according to standard theories. Orthodoxy can allow, though, that apparent counterexamples to closure exist, much as Kripkeans recognize the existence of illusions of possibility which they seek to explain away. Should not everyone, orthodox or not, want to make sense of “intimations of openness”? This paper compares two styles of explanation: evidence that boosts P’s probability need not boost that of its consequence Q; evidence bearing on P’s subject matter may not bear on the subject (...) matter of Q.

The regress of reasons threatens an epistemic agent’s right to claim that any beliefs are justified. In response, Peter Klein’s infinitism argues that an infinite series of supporting reasons of the right type not only is not vicious but can make for epistemic justification. In order to resist the sceptic, infinitism needs to provide reason to think that there is at least one justified belief in the world. Under an infinitist conception this involves showing that at least one belief is (...) supported by an infinite series of supporting reasons. This paper argues that showing this makes problems for the infinitist. The finite minds problem that prevents completion of an infinite series is well documented. This paper examines alternative attempts to provide evidence of infinity that the infinitist might take, whether by using a notion of justification without infinite reasons or by altering the notion of evidence. It concludes that both of these fail and consequently infinitism is unable to offer a solution to Agrippa’s trilemma. (shrink)

Neil Sinhababu and I presented Backward Clock, an original counterexample to Robert Nozick’s truth-tracking analysis of propositional knowledge. Fred Adams, John Barker and Murray Clarke argue that Backward Clock is no such counterexample. Their argument fails to nullify Backward Clock which also shows that other tracking analyses, such as Dretske’s and one that Adams et al. may well have in mind, are inadequate.

In “The Backward Clock, Truth-Tracking, and Safety”, Neil Sinhababu and I gave Backward Clock, a counterexample to Robert Nozick’s truth-tracking analysis of knowledge. In “Knowledge as Fact-Tracking True Belief”, Fred Adams, John Barker and Murray Clarke propose that a true belief constitutes knowledge if and only if it is based on reasons that are sensitive to the fact that makes it true, that is, reasons that wouldn’t obtain if the belief weren’t true. They argue that their analysis evades Backward Clock. (...) Here I show that it doesn’t. Backward Clock likewise shows their analysis to be too weak. The broader lesson seems to be that Backward Clock tells us the time is up for purely modal analyses of knowledge. (shrink)

This paper explicates and argues for the thesis that individual rational judgment, of the kind required for rational justification in non-formal, substantive domains – i.e. in empirical knowledge or in morals (both ethics and justice) – is in fundamental part socially and historically based, although these social and historical aspects of rational justification are consistent with realism about the objects of empirical knowledge and with strict objectivity about basic moral principles. The central thesis is that, to judge fully rationally that (...) one judges – in ways which provide rational justification of one’s judgment about any substantive matter – requires recognising one’s inherent fallibility and consequently also recognising our mutual interdependence for assessing our own and each others’ judgments and their justification. This explication provides a pragmatic account of rational justification in substantive domains which puts paid to the traditional distinction, still influential today, between ‘rational’ and ‘historical’ knowledge. (Note: This paper is a counterpart to Westphal 2011b; each paper contains substantial material not included in the other.). (shrink)

In order to reply to the contemporary skeptic’s argument for the conclusion that we don’t have any empirical knowledge about the external world, several authors have proposed different fallibilist theories of knowledge that reject the epistemic closure principle. Holliday, 1–62 2015a), however, shows that almost all of them suffer from either the problem of containment or the problem of vacuous knowledge or both. Furthermore, Holliday suggests that the fallibilist should allow a proposition to have multiple sets of relevant alternatives, each (...) of which is sufficient while none is necessary, if all its members are eliminated, for knowing that proposition. Not completely satisfied with Holliday’s multi-path reply to the skeptic, the author suggests a new single-path relevant-possibility theory of knowledge and argues that it can avoid both the problem of containment and the problem of vacuous knowledge of a certain sort while rejecting skepticism about the external world.

Crispin Wright’s “Unified Strategy” for addressing some familiar sceptical paradoxes exploits a subtle distinction between two different ways in which we can be related to a proposition: (full-blown) belief and (mere) acceptance. The importance of the distinction for his strategy stems from his conviction that we cannot acquire any kind of evidence, either empirical or a priori, for the “cornerstones” of our cognitive projects, i.e., for those basic presuppositions of our inquiries that we must be warranted to endorse if we (...) are to claim warrant for any of the beliefs formed as a result of such inquiries: regarding the idea of a non-evidential warrant to believe a proposition as a kind of “conceptual solecism”, he doesn’t set himself the task of showing that we are evidentially warranted to believe such presuppositions, but only that of showing that we are non-evidentially warranted to accept them. In the present paper, I argue that such choice involves a fatal departure from a basic principle governing doxastic commitment—a principle that requires that we regard cornerstones propositions as propositions we are rationally committed to believe, not just entitled to accept. I press the point by presenting the Acceptance Argument, a sceptical paradox whose consideration leads to the conclusion that the Unified Strategy is caught between the Scylla of incoherently invoking a rather dubious form of epistemic alchemy and the Charybdis of placing an unexpected and apparently ad hoc restriction on the doxastic commitments we undertake by believing the things we believe. My final suggestion is that the Unified Strategy might be spared this dilemma only by undergoing a rather radical revision—a revision that would require setting aside the distinction between belief and acceptance to re-conceptualise its goal unabashedly in terms of (non-evidentially) warranted belief.

Subjunctivitis is the doctrine that what is distinctive about knowledge is essential modal in character, and thus is captured by certain subjunctive conditionals. One principal formulation of subjunctivism invokes a ``sensitivity condition'' (Nozick, De Rose), the other invokes a ``safety condition'' (Sosa). It is shown in detail how defects in the sensitivity condition generate unwanted results, and that the virtues of that condition are merely apparent. The safety condition is untenable also, because it is too easily satisfied. A powerful motivation (...) for adopting subjunctivism would be that it provides a solution to the problem of misleading evidence, but in fact, it does not. (shrink)

In this paper, I first introduce the main motivations for the internalism/externalism dichotomy in epistemology and explore different accounts of epistemic justification, mostly externalist, arising from Dretske’s relevant alternatives theory of knowledge, namely the reliabilism of Goldman and Nozick, the contextualism of Cohen and DeRose, which is governed by fallibilist standards, and Lewis’ version of contextualism, to which infallibilist standards apply. I then argue that Wittgenstein critically anticipates many of these strategies and tries to avoid such a dichotomy by assuming (...) a form of infallibilism which is neither internal nor external. After introducing the idea of a Wittgensteinian hinge epistemology and how it responds to the problem of epistemic justification and to the particular challenge posed by radical scepticism, I defend the view that infallibility is logically unavoidable when we realize that we are always trapped in one language-game or another, even if we constantly switch between language-games.

The conclusive reasons view of knowledge entails the “abominable conjunction” that I know that I have hands but I do not know that I am not a brain in a vat. The argument from abomination takes this as a reason to reject the view. This paper aims to buttress the argument from abomination by adding a new sort to this list: the logical abominations. These include: “I know that argument is sound and that sound arguments have true conclusions but I (...) don’t know whether the conclusion of that argument is true”. Two standard replies to the argument from abomination are raised. It is argued that the logical abominations open new holes in both. (shrink)

In a Normal Case, a subject has a justified true belief that P and also knows that P. In a Gettier Case, a subject has a justified true belief that P but does not know that P.

I argue that the received view is mistaken and I discuss the implications this has (...) on some other epistemological issues. (shrink)

Although the fallible/infallible distinction in the theory of knowledge has traditionally been upheld by most epistemologists, almost all contemporary theories of knowledge claim to be fallibilist. Fallibilists have, however, been forced to accommodate knowledge of necessary truths. This has proved to be a daunting task, not least because there is as yet no consensus on how the fallible/infallible divide is to be understood. In this article, after examining and rejecting a number of representative accounts of the notion of fallible knowledge, (...) I argue that the main problems with these accounts actually stem from the very coherence of that notion. I then claim that the distinction is best understood in terms of the externalist/internalist conceptions of knowledge. Finally, I seek to garner some independent support for the proposal by highlighting some of its consequences, including its surprising bearing on certain recent and seemingly distant controversies involving issues in epistemology and philosophy of mind.

There is a virtual consensus in contemporary epistemology that knowledge must be reliably produced. Everyone, it seems, is a reliabilist about knowledge in that sense. I present and defend two arguments that unreliable knowledge is possible. My first argument proceeds from an observation about the nature of achievements, namely, that achievements can proceed from unreliable abilities. My second argument proceeds from an observation about the epistemic efficacy of explanatory inference, namely, that inference to the best explanation seems to produce knowledge, (...) even if it isn't reliable. I also propose a successor to standard versions of reliabilism, which I call ‘ecumenical reliabilism’. Ecumenical reliabilism is consistent with unreliably produced knowledge and helps explain why unreliably produced knowledge is possible. (shrink)

Having direct doxastic control would not be particularly desirable if exercising it required a failure of epistemic rationality. With that thought in mind, recent writers have invoked the view that epistemic rationality gives us options to defend the possibility of a significant form of direct doxastic control. Specifically, they suggest that when the evidence for p is sufficient but not conclusive, it would be epistemically rational either to believe p or to be agnostic on p, and they argue that we (...) can in these cases effectively decide to form either attitude without irrationality. This paper argues against the version of epistemic permissivism invoked by these writers and shows that other plausible versions of permissivism do not support their cause. It concludes that if we can exercise direct doxastic control without irrationality, it is not because epistemic rationality gives us options. (shrink)

It is argued that a number of important, and seemingly disparate, types of representation are species of a single relation, here called structural representation, that can be described in detail and studied in a way that is of considerable philosophical interest. A structural representation depends on the existence of a common structure between a representation and that which it represents, and it is important because it allows us to reason directly about the representation in order to draw conclusions about the (...) phenomenon that it depicts. The present goal is to give a general and precise account of structural representation, then to use that account to illuminate several problems of current philosophical interest — including some that do not initially seem to involve representation at all. In particular, it is argued that ontological reductions (like that of the natural numbers to sets), compositional accounts of semantics, several important sorts of mental representation, and (perhaps) possible worlds semantics for intensional logics are all species of structural representation and are fruitfully studied in the framework developed here.

Perception is typically distinguished from cognition. For example, seeing is importantly different from believing. And while what one sees clearly influences what one thinks, it is debatable whether what one believes and otherwise thinks can influence, in some direct and non-trivial way, what one sees. The latter possible relation is the cognitive penetration of perception. Cognitive penetration, if it occurs, has implications for philosophy of science, epistemology, philosophy of mind, and cognitive science. This paper offers an analysis of the phenomenon, (...) its theoretical consequences, and a variety of experimental results and possible interpretations of them. The paper concludes by proposing some constraints for analyses and definitions of cognitive penetrability. (shrink)

Amongst philosophers and cognitive scientists, modularity remains a popular choice for an architecture of the human mind, primarily because of the supposed explanatory value of this approach. Modular architectures can vary both with respect to the strength of the notion of modularity and the scope of the modularity of mind. We propose a dilemma for modular architectures, no matter how these architectures vary along these two dimensions. First, if a modular architecture commits to the informational encapsulation of modules, as it (...) is the case for modularity theories of perception, then modules are on this account impenetrable. However, we argue that there are genuine cases of the cognitive penetrability of perception and that these cases challenge any strong, encapsulated modular architecture of perception. Second, many recent massive modularity theories weaken the strength of the notion of module, while broadening the scope of modularity. These theories do not require any robust informational encapsulation, and thus avoid the incompatibility with cognitive penetrability. However, the weakened commitment to informational encapsulation greatly weakens the explanatory force of the theory and, ultimately, is conceptually at odds with the core of modularity. (shrink)

This paper aims to show that Sosa’s theory of knowledge based on safety condition can provide a convincing response to the problem of philosophical skepticism. With regard to that, it is divided in three sections. The first section is dedicated to presenting the form of skeptical argument and few options we encounter when skeptic rises the challenge in the form of the so-called radical alternatives. The second section consists of the presentation of Sosa’s theory and safety condition, as well as (...) its differences and similarities with Nozick’s sensitivity condition and Dretske’s condition of conclusive reason. Finally, the third section evaluates Sosa’s theory in the light of Comesana’s counterexample. After the careful analysis of the hypothetical situation, it is shown that Comesana overlooks one important moment when he fixes the initial set of circumstances, which allows a successful defense of Sosa’s analysis of knowledge and safety condition.
