happens, how it happens, and why it happens. Our assumption ought to be that this is as true in education as it is in atomic physics. But this leaves many other questions to answer. The crucial ones: What kind of science is proper or appropriate to education? How does it differ from physics? What is wrong with the prevai1~ ing, virtually unopposed research tradition in education? What could or should be done to replace it with a more adequate tradi tion? (...) What concepts are necessary to describe and explain what we find there? It is in this realm that we find ourselves. Where to start? One place - our place, needless to say - is with one limited but central concept in education, teaching. A long philosophical tradition concerned with the nature of teaching goes back (along with everything else) to Plato, divulging most recent ly in the work of such philosophers as B. O. Smith, Scheffler, Hirst, Komisar, Green, McClellan, Soltis, Kerr, Fenstermacher, et al. An empirical tradition runs parallelto the philosophers -it has its most notable modern proponents in Gage, the Soars, Berliner, Rosen shine, but its roots can be traced to the Sophists. These two tradi tions have been at loggerheads over the centuries. (shrink)

In responding to and examining Mary Anne Raywid's adoption of community building as an aim for schools, I survey a number of types of communities, including recreational, intentional and language communities. In considering all these communities, I try to show both the power of communities in our personal lives and some idea of why we might be of two minds about promoting community as an ideal in the modern world and in schools in particular.

The New Evil Demon problem has been hotly debated since the case was introduced in the early 1980’s (e.g. Lehrer and Cohen 1983; Cohen 1984), and there seems to be recent increased interest in the topic. In a forthcoming collection of papers on the New Evil Demon problem (Dutant and Dorsch, forthcoming), at least two of the papers, both by prominent epistemologists, attempt to resist the problem by appealing to the distinction between justification and excuses. My primary aim here is (...) to critically evaluate this new excuse maneuver as a response to the New Evil Demon problem. -/- Their response attempts to give us reason to reject the idea that victims of the New Evil Demon have justification for believing as they do. I shall argue that this approach is ultimately unsuccessful, however much of value can be learned from these attempts. In particular, progress in the debate can be made by following those who advance the excuse maneuver and make explicit the connection between epistemic justification and epistemic norms. By doing so, the questions being debated are clarified, as is the methodology being used to attempt to answer them. (shrink)

In common with traditional forms of epistemic internalism, epistemological disjunctivism attempts to incorporate an awareness condition on justification. Unlike traditional forms of internalism, however, epistemological disjunctivism rejects the so-called New Evil Genius thesis. In so far as epistemological disjunctivism rejects the New Evil Genius thesis, it is revisionary. -/- After explaining what epistemological disjunctivism is, and how it relates to traditional forms of epistemic internalism / externalism, I shall argue that the epistemological disjunctivist’s account of the intuitions underlying the New (...) Evil Genius thought experiment is at best incomplete. As presented, therefore, epistemological disjunctivism is unable to accommodate the core guiding intuitions of epistemic internalism. Given the stated aim of not being revisionary on this score, the view is at a dialectical disadvantage over the traditional forms of epistemic internalism the position is meant to replace. Unfortunately, therefore, at present, the impasse between internalism and externalism remains. (shrink)

In this article I argue that the value of epistemic justification cannot be adequately explained as being instrumental to truth. I intend to show that false belief, which is no means to truth, can nevertheless still be of epistemic value. This in turn will make a good prima facie case that justification is valuable for its own sake. If this is right, we will have also found reason to think that truth value monism is false: assuming that true belief does (...) have value, there is more of final epistemic value than mere true belief. (shrink)

What makes an intellectual virtue a virtue? A straightforward and influential answer to this question has been given by virtue-reliabilists: a trait is a virtue only insofar as it is truth-conducive. In this paper I shall contend that recent arguments advanced by Jack Kwong in defence of the reliabilist view are good as far as they go, in that they advance the debate by usefully clarifying ways in how best to understand the nature of open-mindedness. But I shall argue that (...) these considerations do not establish the desired conclusions that open-mindedness is truth-conducive. To establish these much stronger conclusions we would need an adequate reply to what I shall call Montmarquet’s objection. I argue that Linda Zagzebski’s reply to Montmarquet’s objection, to which Kwong defers, is inadequate. I conclude that it is contingent if open-mindedness is truth-conducive, and if a necessary tie to truth is what makes an intellectual virtue a virtue, then the status of open-mindedness as an intellectual virtue is jeopardised. We either need an adequate reliabilist response to Montmarquet’s objection, or else seek alternative accounts of what it is that makes a virtue a virtue. I conclude by briefly outlining some alternatives. (shrink)

One thing nearly all epistemologists agree upon is that Gettier cases are decisive counterexamples to the tripartite analysis of knowledge; whatever else is true of knowledge, it is not merely belief that is both justified and true. They now agree that knowledge is not justified true belief because this is consistent with there being too much luck present in the cases, and that knowledge excludes such luck. This is to endorse what has become known as the 'anti-luck platitude'. <br /><br (...) />But what if generations of philosophers have been mistaken about this, blinded at least partially by a deeply entrenched professional bias? There has been another, albeit minority, response to Gettier: to deny that the cases are counterexamples at all. <br /><br />Stephen Hetherington, a principal and vocal proponent of this view, advances what he calls the 'Knowing Luckily Proposal'. If Hetherington is correct, this would call for a major re-evaluation and re-orientation of post-Gettier analytic epistemology, since much of it assumes the anti-luck platitude both in elucidating the concept of knowledge, and in the application of such accounts to central philosophical problems. It is therefore imperative that the Knowing Luckily Proposal be considered and evaluated in detail. <br /><br />In this paper I critically assess the Knowing Luckily Proposal. I argue that while it draws our attention to certain important features of knowledge, ultimately it fails, and the anti-luck platitude emerges unscathed. Whatever else is true of knowledge, therefore, it is non-lucky true belief. For a proposition to count as knowledge, we cannot arrive at its truth accidentally or for the wrong reason. (shrink)

In general, epistemic internalists hold that an individual’s justification for a belief is exhausted by her reflectively accessible reasons for thinking that the contents of her beliefs are true. Applying this to the epistemology of testimony, a hearer’s justification for beliefs acquired through testimony is exhausted by her reflectively accessible reasons to think that the contents of the speaker’s testimony is true. A consequence of internalism is that subjects that are alike with respect to their reflectively accessible reasons are alike (...) with respect to what they have justification to believe. Testimony should be thought no different: hearers that are alike with respect to reflectively accessible reasons to think that a speaker’s testimony is true are alike with respect to their justification for beliefs based upon that testimony. But it has been recently argued that this view faces powerful counterexamples. So the central question is this: assuming that a hearer can acquire justification to believe a proposition through the testimony of a speaker, can epistemic internalism provide the resources to explain how such justification is possible? My aim in this paper is to address these counterexamples, and in so doing, defend epistemic internalist accounts of testimony. (shrink)

This chapter first surveys general issues in the epistemic internalism / externalism debate: what is the distinction, what motivates it, and what arguments can be given on both sides. -/- The second part of the chapter will examine the internalism / externalism debate as regards to the specific case of the epistemology of memory belief.

Epistemic internalism, by stressing the indispensability of the subject’s perspective, strikes many as plausible at first blush. However, many people have tended to reject the position because certain kinds of beliefs have been thought to pose special problems for epistemic internalism. For example, internalists tend to hold that so long as a justifier is available to the subject either immediately or upon introspection, it can serve to justify beliefs. Many have thought it obvious that no such view can be correct, (...) as it has been alleged that internalism cannot account for the possibility of the justification of beliefs stored in memory. -/- My aim in this paper is to offer a response that explains how memory justification is possible in a way that is consistent with epistemic internalism and an awareness condition on justification. Specifically, I will explore the plausibility of various options open to internalists, including both foundationalist and non-foundationalist approaches to the structure of justification. I intend to show that despite other difficult challenges that epistemic internalism might face, memory belief poses no special problems that the resources of internalism cannot adequately address. (shrink)

In this paper I consider a recent argument of Timothy Williamson’s that epistemic internalism and content externalism are indeed incompatible, and since he takes content externalism to be above reproach, so much the worse for epistemic internalism. However, I argue that epistemic internalism, properly understood, remains substantially unaffected no matter which view of content turns out to be correct. What is key to the New Evil Genius thought experiment is that, given everything of which the inhabitants are consciously aware, the (...) two worlds are subjectively indistinguishable for them, which is what matters on internalist accounts of epistemic justification. I argue that even if a standard moral of the New Evil Genius intuition is untenable due to considerations arising from content externalism, the case can be understood as supporting epistemic internalism in a way that is wholly compatible with content externalism. In short, epistemic internalism is committed to sameness of justificatory status between subjectively indistinguishable counterparts, not sameness of content of their justifiers. (shrink)

Influential cases have been provided that seem to suggest that one can fail to have knowledge because of the social environment. If not a distinct kind of social defeater, is there a uniquely social phenomenon that defeats knowledge? My aim in this paper is to explore these questions. I shall argue that despite initial appearances to the contrary, we have no reason to accept a special class of social defeater, nor any essentially social defeat phenomenon. We can explain putative cases (...) of social defeat with our existing epistemological apparatus. (shrink)

In its most basic form, Simple Reliabilism states that: a belief is justified iff it is formed as the result of a reliable belief-forming process. But so-called New Evil Demon cases have been given as counterexamples. A common response has been to complicate reliabilism from its simplest form to accommodate the basic reliabilist position, while at the same time granting the force of NED intuitions. But what if despite initial appearances, Simple Reliabilism, without qualification, is compatible with the NED intuition? (...) What we can call the Dispositionalist Response to the New Evil Demon problem is fascinating because it contends just that: Simple Reliabilism is fully compatible with the NED intuition. It is claimed that all we need to do to recognize their compatibility is appreciate that reliability is a dispositional property. In this paper I shall critically evaluate the Dispositionalist proposal. (shrink)

If knowledge requires safety, then one might think that when the epistemic source of knowledge is testimony, that testimony must itself be safe. Otherwise, will not the lack of safety transfer from testimony to hearer, such that hearer will lack knowledge? Resisting this natural line of reasoning, Goldberg (2005; 2007) argues that testimonial knowledge through unsafe testimony is possible on the basis of two cases. Lackey (2008) and Pelling (2013) criticize Goldberg’s examples. But Pelling goes on to provide his own (...) example that attempts to show that Goldberg’s thesis is true: one can gain safe testimonial belief from unsafe testimony. If any of these counterexamples were correct, they would undermine the main reason to think that knowledge based on unsafe testimony is impossible. My aim in this paper is to critically assess these arguments, and to consider the possibility of knowledge through unsafe testimony. Drawing a general moral from the analysis of these cases, I shall contend that it is impossible to acquire safe belief solely on the basis of unsafe testimony. If so, then testimonial knowledge based solely on unsafe testimony is impossible. (shrink)

In addition to the notion of defeat, do we need to expand the epistemological repertoire used in accounting for the context dependence of justification? It has recently been argued that we ought to admit a hitherto unrecognized fundamental epistemic kind called ‘disqualifiers’. Disqualifiers are taken to be not reducible to any other epistemic notion. Rather, they are meant to be primitive. If this is correct, it is a surprising and novel discovery, and so it is worthy of further epistemological investigation. (...) In this paper I shall first argue that the cases given do not motivate positing the notion of a disqualifier. Conclusions drawn about the existence of disqualifiers do not follow from the considerations advanced. Second, I shall directly argue that an essential core claim of those who would posit disqualifiers, that so-called disqualifiers actually do prevent epistemic bases from conferring justification, is false. In sum, I shall argue that there are no disqualifiers. (shrink)

Vice epistemology, as Quassim Cassam understands it, is the study of the nature, identity, and significance of the epistemic vices. But what makes an intellectual vice a vice? Cassam calls his own view “Obstructivism” – intellectual vices are those traits, thinking styles, or attitudes that systematically obstruct the acquisition, retention, and transmission of knowledge. -/- I shall argue that Cassam’s account is an improvement upon virtue-reliabilism, and that it fares better against what I call Montmarquet’s objection than its immediate rivals. (...) Nevertheless, I contend that it does not go far enough — Montmarquet’s objection stands. -/- I conclude that either the objection needs to be answered in some other way, or else proponents of Obstructivism need to explain why their account of the nature of the intellectual vices does not have the counterintuitive consequences it appears to have. Alternatively, another account of the nature of the intellectual vices needs to be sought. (shrink)

In The Realm of Reason (2004), Christopher Peacocke develops a “generalized rationalism” concerning, among other things, what it is for someone to be “entitled”, or justified, in forming a given belief. In the course of his discussion, Peacocke offers two arguments to the best explanation that aim to undermine scepticism and establish a justification for our belief in the reliability of sense perception, respectively. If sound, these ambitious arguments would answer some of the oldest and most vexing epistemological problems. In (...) this paper I will evaluate these arguments, concluding that they are inconclusive at best. Despite offering some interestingly original arguments, Peacocke gives us no reason to think that scepticism is false, and that perception is generally reliable. (shrink)

What does it take for a positive epistemic status to obtain? I argue throughout my thesis that if a positive epistemic status obtains, this is not a brute fact. Instead, if for example a belief is justified, it is justified in virtue of some further condition(s) obtaining. A fundamental topic in epistemology is the question of what sorts of factors can be relevant to determining the positive epistemic status of belief. Epistemic Internalism holds that these factors must be “internal” (in (...) a sense that needs to be specified). Epistemic Externalism is the denial of internalism. My thesis is an explanation and defense of an internalist theory of epistemic justification. -/- The central claim of my thesis is that something is “internal” in this sense only if it is, or can easily be, the object of the agent’s conscious awareness. By considering key cases, I show that without an awareness requirement on justification, the subject cannot avoid what I call the Subject’s Perspective Objection. In developing this objection I examine and respond to an argument against the awareness requirement which claims that such awareness either leads to a vicious regress of requiring higher order beliefs of increasing complexity (if any beliefs are to be justified), or else requiring such awareness is unmotivated. This regress is generated because it is assumed that the relevant kind of awareness must be doxastic. My solution invokes what I call ‘strong non-doxastic awareness’ that grounds non-inferential justification and thereby avoids this dilemma, while meeting the Subject’s Perspective Objection. -/- I also argue that external factors, such as the reliability (actual or conditional) of the mechanism supporting the belief, are not necessary for justification. I argue for this conclusion by comparing what constitutes justified belief in the actual world with one’s counterpart in a ‘demon world’. I argue that this intuition, correctly interpreted, counts in favour of internalism. As I explain, many philosophers moved by arguments presented by externalists about mental content deny that such a case is possible. In opposition I argue that the awareness requirement remains substantially unaffected, no matter which view of content turns out to be correct. What is key is that the two worlds are completely subjectively indistinguishable from each other for those who inhabit them in all the ways of which they are consciously aware. -/- If neither the obtaining of truth nor reliability is necessary for epistemic justification, what makes justification genuinely epistemic? In the final chapter I argue against recent work that assimilates justification with knowledge, as well as for a positive account of the truth connection. As to the former question, I defend the orthodoxy that they are distinct epistemic statuses; as to the latter, I argue that the connection between justification and truth is conceptual. That is, epistemic justification is epistemic because it turns on evidence; evidence is epistemic because it is conceptually linked with truth. Epistemic justification, therefore, is conceptually linked with the truth (via evidence), which is what makes it distinctively epistemic. -/- In short, this thesis is an explanation and defense of an internalist theory of epistemic justification. The central claim of the thesis is that something is “internal” in this sense only if it is, or can easily be, the object of the agent’s conscious awareness. I argue that conscious awareness is a necessary condition of epistemic justification obtaining, and that factors external to consciousness play no justificatory role. (shrink)

My thesis is on the intersection of epistemology and the philosophy of religion. Contemporary religious epistemology asks the question of how, if at all, can religious belief be rationally justified. I focus on a relatively new tradition that responds to this question known as Reformed Epistemology, as advanced by Alvin Plantinga. Reformed Epistemologists argue that belief in God can be rational, reasonable, and justified without appeal to evidence as was traditionally thought. Plantinga argues that religious belief stems from an innate (...) faculty which produces properly basic beliefs that need not rest on any other beliefs for their justification. My aim is to critically examine these claims. My thesis begins in section I with a discussion of Plantinga’s early attacks on classical foundationalism and Evidentialism, that is, the view that being rational means according one's belief with the evidence. His early goal is to discredit the Evidentialist objection by rebutting the flawed epistemological system he argues it presupposes. In so doing, Plantinga attempts to loosen the canons of basicality to include the belief in God as properly basic. -/- In section II I then discuss Plantinga’s notion of warrant, which is his term for justification – the hallmark difference between true belief and knowledge. After examining the tenability of Plantinga’s concept of what makes belief warranted, I examine how successfully he specifically applies this notion of justification to religious belief. Plantinga’s contention is that religious belief can enjoy enough warrant so that if the belief is true, it will constitute knowledge. In examining this claim I evaluate in section III Plantinga’s evolutionary argument against naturalism, his Aquinas/Calvin model in section IV, potential rationality defeaters in section V and in section VI the larger question of the internalism / externalism debate and its influence on these central issues.

We consider various curious features of general relativity, and relativistic field theory, in two spacetime dimensions. In particular, we discuss: the vanishing of the Einstein tensor; the failure of an initial-value formulation for vacuum spacetimes; the status of singularity theorems; the non-existence of a Newtonian limit; the status of the cosmological constant; and the character of matter fields, including perfect fluids and electromagnetic fields. We conclude with a discussion of what constrains our understanding of physics in different dimensions.

Threonine is an essential amino acid for mammals and birds and an adequate supply is necessary for growth and maintenance. Its production has become the aim of metabolic bioengineering and genetic manipulations. We propose in this paper a rational approach for increasing threonine production in anE. coli strain based on metabolic control theory. We have derived a way to measure the control coefficients of threonine pathwayin vivo. The method consists in modelling the results of presteady-state experiments. Thein vivo concentrations and (...) activities of the enzymes can then be measured and introduced into the model, so that thein vivo steady-state of the pathway can be evaluated. With such a model it is possible to calculate the theoretical values of the control coefficients of the threonine synthesis fluxin vivo. (shrink)

The sequencing of the human genome and decreasing costs of sequencing technology have led to the notion of ‘personalized medicine’. This has been taken by some authors to indicate that personalized medicine will provide individualized treatments solely based on one’s DNA sequence. We argue this is overly optimistic and misconstrues the notion of personalization. Such interpretations fail to account for economic, policy and structural constraints on the delivery of healthcare. Furthermore, notions of individualization based on genomic data potentially take us (...) down the road of genetic reductionism obscuring the role of environmental factors in disease and ill health. We propose that one should see personalized medicine as a way of using personal genomic information to stratify individuals into subpopulations and suggest that personalized medicine be seen within a broader idea of personalized healthcare, reflecting healthcare that integrates personal genomic data into cultural, environmental and personal contexts.
