The view that contradictions cannot be true has been part of accepted philosophical theory since at least the time of Aristotle. In this regard, it is almost unique in the history of philosophy. Only in the last forty years has the view been systematically challenged with the advent of dialetheism. Since Graham Priest introduced dialetheism as a solution to certain self-referential paradoxes, the possibility of true contradictions has been a live issue in the philosophy of logic. Yet, despite the arguments (...) advanced by dialetheists, many logicians and philosophers still hold the opinion that contradictions cannot be true. -/- Rather than advocating the truth of certain contradictions, this thesis offers a different challenge to the classical logician. By showing that it can be philosophically coherent to propose that true contradictions are metaphysically possible, the thesis suggests that the classical logician must do more than she currently has to justify her confidence in the impossibility of true contradictions. Simply fighting off the dialetheist’s putative examples of true contradictions at the actual world isn’t enough to justify the classical logician’s conclusion that true contradictions are impossible. -/- To aid the thesis dialectically, we introduce a new position, absolutism, which hypothesises that it’s metaphysically possible for at least one contradiction to be true, contrasting with the dialetheic hypothesis that some contradictions are true in the actual world. We demonstrate that absolutism can be given a philosophically coherent interpretation, an appropriate logic, and that certain criticisms are completely toothless against absolutism. The challenge put to the classical logician is then: On what logical or philosophical grounds can we rule out the metaphysical possibility of true contradictions? (shrink)

Mental imagery often occurs during testimonial belief transmission: a testifier often episodically remembers or imagines a scene while describing it, while a listener often imagines that scene as it’s described to her. I argue that getting clear on imagery’s psychological roles in testimonial belief transmission has implications for some fundamental issues in the epistemology of testimony. I first appeal to imagery cases to argue against a widespread “internalist” approach to the epistemology of testimony. I then appeal to the same sort (...) of case to argue for an alternative, externalist view. (shrink)

Two ideas shape the epistemology of testimony. One is that testimony provides a unique kind of knowledge. The other is that testimonial knowledge is a social achievement. In traditional terms, those who affirm these ideas are anti-reductionists, and those who deny them are reductionists. There is increasing interest, however, in the possibility of affirming these ideas without embracing anti-reductionism. Thus, Sanford Goldberg uses the idea of epistemic buck-passing to argue that even reductionists can accept the uniqueness of testimonial knowledge, and (...) Jennifer Lackey gives both speaker and hearer an essential role in testimonial justification, rejecting both reductionism and anti-reductionism in favor of what she calls dualism. After distinguishing a weaker and a stronger notion of buck-passing, we show how anti-reductionists can use the stronger notion to motivate their position, and to answer Goldberg’s and Lackey’s challenges.

This article discusses the following question: what epistemic relation must audiences bear to the content of assertions in order to gain testimonial knowledge? There is a brief discussion of why this issue is of importance, followed by two counterexamples to the most intuitive answer: that in order for an audience to gain testimonial knowledge that p they must know that the speaker has asserted p. It is then suggested that the argument generalises and can be made to work on different (...) sets of assumptions about the conditions for knowledge, and the conditions under which a proposition is asserted.

Much of the plausibility of epistemic conservatism derives from its prospects of explaining our rationality in holding memory beliefs. In the first two parts of this paper, I argue for the inadequacy of the two standard approaches to the epistemology of memory beliefs, preservationism and evidentialism. In the third, I point out the advantages of the conservative approach and consider how well conservatism survives three of the strongest objections against it. Conservatism does survive, I claim, but only if qualified in (...) certain ways. Appropriately qualified, conservatism is no longer the powerful anti-skeptical tool some have hoped for, but a doctrine closely connected with memory. (shrink)

A discussion of L.A. Paul's 'Transformative Experience' from an Author Meets Critics session at the 2015 Pacific APA.

Tyler Burge offers a theory of testimony that allows for the possibility of both testimonial a priori warrant and testimonial a priori knowledge. I uncover a tension in his account of the relationship between the two, and locate its source in the analogy that Burge draws between testimonial warrant and preservative memory. I contend that this analogy should be rejected, and offer a revision of Burge's theory that eliminates the tension. I conclude by assessing the impact of the revised theory (...) on the scope of a priori knowledge. (shrink)

A selective annotated bibliography of recent literature on a priori knowledge.

Tyler Burge defends the idea that memory preserves beliefswith their justifications, so that memory's role in inferenceadds no new justificatory demands. Against Burge's view,Christensen and Kornblith argue that memory is reconstructiveand so introduces an element of a posteriori justificationinto every inference. I argue that Burge is right,memory does preserve content, but to defend this viewwe need to specify a preservative mechanism. Toward thatend, I develop the idea that there is something worthcalling anaphoric thinking, which preserves content inBurge's sense of ``content (...) preservation.'' I providea model on which anaphoric thought is a fundamentalfeature of cognitive architecture, consequentlyrejecting the idea that there are mental pronounsin a Language of Thought. Since preservativememory is a matter of anaphoric thinking, thereare limits on the analogy of memory and testimony. (shrink)

A natural view of testimony holds that a source's statements provide one with evidence about what the source believes, which in turn provides one with evidence about what is true. But some theorists have gone further and developed a broadly analogous view of memory. According to this view, which this essay calls the “diary model,” one's memory ordinarily serves as a means for one's present self to gain evidence about one's past judgments, and in turn about the truth. This essay (...) rejects the diary model's analogy between memory and testimony from one's former self, arguing first that memory and a diary differ with respect to their psychological roles, and second that this psychological difference underwrites important downstream epistemic differences. The resulting view stands opposed to prominent discussions of memory and testimony, which either, like the diary model, treat memory by analogy to what we naively wish to say about testimony, or which instead attempt to extend to testimony the epistemically preservative role of memory.

Contemporary epistemologists typically define a priori justification as justification that is independent of sense experience. However, sense experience plays at least some role in the production of many paradigm cases of a priori justified belief. This raises the question of when experience is epistemically relevant to the justificatory status of the belief that is based on it. In this paper, I will outline the answers that can be given by the two currently dominant accounts of justification, i.e. evidentialism and reliabilism. (...) While for the evidentialist, experience is epistemically relevant only if it is used as evidence, the reliabilist requires that the reliability of the relevant process depends on the reliability of experiential processes. I will argue that the reliabilist account accommodates our pre-theoretic classifications much better. In the final part of my paper I will use the reliabilist criterion to defend the a priori—a posteriori distinction against recent challenges by Hawthorne and Williamson. (shrink)

The purpose of this article is to explore the epistemological foundations of narrative research in education. In particular, I seek to explain how one can obtain knowledge, given its origin in teachers' subjective experiences. The problem with rhetorical and aesthetic criteria that narrative researchers use to warrant their knowledge claims is not that they don't meet a correspondence criterion of truth as post-positivists contend, but rather that they fail to connect teachers' ethical views with their practice. Since narrative research is (...) aimed at understanding teachers' actions and not at seeking some kind of mechanism in teachers' behaviour, the link between past experiences and present teaching practice is not causal but teleological. I suggest that although the knowledge claims of narrative researchers may not be justified (because they don't meet the criteria of truth as correspondence theory), we might nonetheless be intellectually entitled to accept them. Entitlement is an epistemic right or warrant that constitutes knowledge as justification, but uses different reasons—teleological not causal explanations. I offer three criteria to establish entitlement to accept narrative researchers' findings: (1) the meeting of rhetorical standards such as plausibility, adequacy, and persuasion; (2) the inclusion of teachers' stories about their pedagogical practice; (3) the meeting of ethical criteria that connects a teacher's actions to an articulate and defensible end-in-view or vision of the good.

What is the epistemological role of speech perception in comprehension? More precisely, what is its role in episodes or states of comprehension able to mediate the communication of knowledge? One answer, developed in recent work by Tyler Burge, has it that its role may be limited to triggering mobilizations of the understanding. I argue that, while there is much to be said for such a view, it should not be accepted. I present an alternative account, on which episodes of comprehension (...) are better able to underwrite the interpersonal transmission of knowledge. (shrink)

Burge proposes the Acceptance Principle"", which states that it is apriori that a hearer may properly accept what she is told in the absence of defeaters, since any giver of testimony is a rational agent, and as such one can presume she is a ""source of truth"". It is claimed that Burge's Principle is not intuitively compelling, so that a suasive, not merely an explanatory justification for it is needed.
