It is argued that a subject's evidence consists of all and only the propositions that the subject knows.

Since publication of the 1986 Carnegie Commission report, A Nation Prepared: Teachers for the 21st Century, the professional teaching standards movement has gained noticeable momentum. The professional standards movement in teaching has been fueled by national organizations such as the National Council for Accreditation of Teacher Education, the Interstate New Teachers Assessment and Support Consortium, the National Board for Professional Teaching Standards, the National Commission on Teaching and America's Future, and by close collaboration among these four entities. Further, nearly all (...) of the fifty states are embracing the professional standards movement through formal participation in the work of one or more of these organizations. Although the professional standards movement in teaching is strong and growing stronger, its implications are not clear for instructional programs in social foundations of education, either at the teacher preparation or the advanced graduate levels. In response to the standards movement, social foundations educators have a number of options before them, three of which are to (1) largely ignore these developments, as "this too shall pass"; (2) critically interpret and resist these developments through scholarship and collective professional action, as social foundations scholars did with Competency Based Teacher Education in the 1970s; and (3) critically interpret these developments while working to strengthen the potential of the professional teaching standards movement to achieve its stated goal of providing caring and qualified teachers for every classroom in the nation. Of these three options, the last is most advisable, but it presents a considerable challenge to social foundations educators. Although the absence of social foundations skills, perspectives, and understanding should make it very difficult for teacher candidates and teachers to perform well on standards-based teaching assessments, there is no guarantee that these assessments will hold candidates accountable for social foundations learning. Implications for social foundations educators and activists are significant. (shrink)

O meu objetivo neste artigo é mostrar que o teísmo cético, particularmente a versão proposta por Wykstra em “O obstáculo humiano aos argumentos indiciários do mal: evitar os males da ‘aparência”’, não é uma resposta satisfatória para o problema do mal. Para tanto, desenvolvo duas linhas de raciocínio. Em primeiro lugar, argumento que um princípio central na resposta de Wykstra, a condição de acesso epistêmico razoável, não é condição necessária para a evidência; em seguida, mostro que o argumento por analogia (...) proposto por ele falha ou conduz a uma versão social do problema do mal.

, Peter Achinstein argues against the long-standing claim that ‘evidence’ is ambiguous in possessing a sense of confirming evidence and a sense of supporting evidence. He argues that explications of supporting evidence will necessarily violate his contentions that evidence is a discontinuous ‘threshold concept’ and that any philosophical account of supporting evidence will be too weak to be useful to working scientists. But an account of supporting evidence may be formulated which includes Achinstein's notion of epistemic thresholds that finds examples (...) in Achinstein's own historical case studies.

The notion of a severe test has played an important methodological role in the history of science. But it has not until recently been analyzed in any detail. We develop a generally Bayesian analysis of the notion, compare it with Deborah Mayo’s error-statistical approach by way of sample diagnostic tests in the medical sciences, and consider various objections to both. At the core of our analysis is a distinction between evidence and confirmation or belief. These notions must be kept separate (...) if mistakes are to be avoided; combined in the right way, they provide an adequate understanding of severity. Those who think that the weight of the evidence always enables you to choose between hypotheses “ignore one of the factors (the prior probability) altogether, and treat the other (the likelihood) as though it ...meant something other than it actually does. This is the same mistake as is made by someone who has scruples about measuring the arms of a balance (having only a tape measure at his disposal ...), but is willing to assert that the heavier load will always tilt the balance (thereby implicitly assuming, although without admitting it, that the arms are of equal length!).

A aceitação ou a escolha de uma teoria científica por parte de uma comunidade científica é um evento ou processo central na dinâmica científica. É, também, um evento ou processo complexo –já que dele participam as teorias, a experiência e alguma forma de relação inferencial entre a teoria e a experiência.

For any normative domain, we can theorize about what is good in that domain. Such theories include utilitarianism, a view about what is good morally. But there are many domains other than the moral; these include the prudential, the aesthetic, and the intellectual or epistemic. In this last domain, it is good to be knowledgeable and bad to ignore evidence, quite apart from the morality, prudence, and aesthetics of these things. This dissertation builds a theory that stands to the epistemic (...) domain as utilitarianism stands to the moral domain. It builds an epistemic value theory. (shrink)

This essay purports to be a “negative” defense of acquaintance foundationalism. It is “negative” in that I do not do much in the way of advancing novel argument for the position, nor do I extend the position very much. Rather, I focus on demonstrating that the position has the resources to overcome objections that have been proposed to it. In particular, I argue that it can overcome the dilemma proposed by Wilfrid Sellars and developed by Laurence BonJour against foundationalism, as (...) well as dilemmas proposed by Jack Lyons and Michael Bergmann targeting internalism. Acquaintance foundationalism is what I will call any theory of justification that is internalist in what may justify us, foundationalist in the structure of justification, and relies on the concept of acquaintance in justifying our basic beliefs. Internalism requires that what justifies us improves the belief from the perspective of the believing subject. Foundationalism states that the justification for all beliefs depends ultimately on basic beliefs. Finally, acquaintance is a relation between a person and other things such that these other things are before the “mind’s eye” of the subject. The general idea behind each of these dilemmas, so I will argue, is to claim that acquaintance foundationalism cannot provide epistemic reasons for basic beliefs, where epistemic reason means something that contributes to justification from the subject’s perspective. Each dilemma will ask whether the alleged justifier has some feature x. However, each dilemma contends that, whether the alleged has the feature x or not, it cannot serve as an epistemic reason. For example, BonJour will ask whether our allegedly basic beliefs are cognitive or not. He argues that if they are cognitive, they need justification, but if they are not cognitive, they cannot provide justification. Thus, no allegedly basic belief can serve as an epistemic reason. I argue that the notion of acquaintance allows us to escape such dilemmas because our states of acquaintance allow us to justify our basic beliefs without requiring justification themselves. I do so by borrowing, in part, Richard Fumerton’s theory of non-inferential justification, plus adding on a few epicycles to allow us to base our basic beliefs on our acquaintances. The first chapter sets up the issues of the dissertation: it gives context to the project, defines acquaintance foundationalism and epistemic reason, and discusses our dilemmas in broad outline. It also summarizes the rest of the essay. I use epistemic reasons in a specialized sense in the dissertation, which necessitates an extended discussion. This is the focus of chapter two. I argue that an epistemic reason is a mental complex that consists of Fumertonian acquaintances. When we have an epistemic reason, we have a mental complex that is related in the appropriate way to a belief. This is just what provides justification for the belief. This chapter explicates this notion. It includes an extended discussion of Richard Fumerton’s theory of non-inferential justification, which I follow in outline but diverge from in detail. This discussion focuses on his notion of acquaintance, and the items with which we may be acquainted. I then move to a discussion of the metaphysics of epistemic reasons, explaining how they consist of these acquaintances. I also discuss the relationship between epistemic reasons and epistemic justification. The third chapter is historical in focus. I examine Sellars’s famous dilemma for foundationalism, and contend that it can be best understood as an attempt to deny the foundationalist epistemic reasons for his beliefs. I also examine Laurence BonJour’s later formulation of the Sellarsian dilemma, and again argue that it is best understood as denying epistemic reasons to foundationalists. I then review the options that an acquaintance foundationalist has to respond to these dilemmas, as these responses will allow us to see where our more recent dilemmas go wrong. Chapter four address Jack Lyons’s dilemma. I consider what Lyons says about his dilemma at some length. I then argue that it is structurally similar to the Sellarsian dilemma, and tries to undermine the internalist’s ability to offer epistemic reasons for his beliefs. I then argue that Lyons’s dilemma only seems persuasive because he misunderstands what is required for experience to provide us with an epistemic reason. When properly understood, his dilemma fails to tell against the acquaintance foundationalism. I also argue that Lyons’s version of externalism is much more radical than it might initially appear, helping to motivate acquaintance foundationalism. The fifth chapter focuses on Michael Bergmann. I give his dilemma an extended discussion, which I follow up by reframing it in terms of epistemic reasons. I argue that his dilemma, while seemingly persuasive, fails to trouble the acquaintance foundationalism. I argue that we may be strongly aware of our epistemic reasons without starting a regress, which vitiates his dilemma. I conclude with some short remarks on possibility of skepticism. (shrink)
