In defence of gullibility: the epistemology of testimony and the psychology of deception detection

Research in the psychology of deception detection implies that Fricker, in making her case for reductionism in the epistemology of testimony, overestimates both the epistemic demerits of the antireductionist policy of trusting speakers blindly and the epistemic merits of the reductionist policy of monitoring speakers for trustworthiness: folk psychological prejudices to the contrary notwithstanding, it turns out that monitoring is on a par (in terms both of the reliability of the process and of the sensitivity of the beliefs that it produces) with blind trust. The consequence is that while (a version of) Fricker’s argument for the necessity of a reduction succeeds, her argument for the availability of reductions fails. This does not, however, condemn us to endorse standard pessimistic reductionism, according to which there is no testimonial knowledge, for recent research concerning the methods used by subjects to discover deception in non-laboratory settings suggests that only a more moderate form of pessimism is in order.     

In defense of a critical-presentist historiography: the fact-theory relationship and Marx's epistemology.

It is argued that mainstream social scientists made an "error" during the crucial formative years of the 1920s and 1930s. This historical error involved relinquishing, or at the very least ignoring, some of the epistemological views within the social sciences concerning the fact-theory relationship as developed by Marx and others in his tradition. The contemporary nature of some of Mark's epistemic views is demonstrated, where the case is made that some recent developments in the philosophy of science are converging with some of his original insights. The methodological approach of the article--judging the past in the context of the present--is defended on the basis of Marxian historiography, especially as developed by those noe-Marxists of the Frankfurt School. In the latter discussion "justificationist presentism" is criticized from the perspective of a "critical presentism."     

Speaking freely: on free will and the epistemology of testimony

Peter Graham has recently given a dilemma purportedly showing the compatibility of libertarianism about free will and the anti-skeptical epistemology of testimony. In the first part of this paper I criticize his dilemma: the first horn either involves a false premise or makes the dilemma invalid. The second horn relies without argument on an implausible assumption about testimonial knowledge, and even if granted, nothing on this horn shows libertarianism does not entail skepticism about testimonial justification. I then argue for the incompatibility of (i) a view entailed by Open Theism, viz., that there are no true counterfactuals of freedom, (ii) a popular form of process reliabilism about justification and knowledge, and (iii) a weak anti-skepticism about testimonial justification and knowledge. I conclude that there is a costly tension between certain views about testimony and about free will.     

Lexical norms,language comprehension,and the epistemology of testimony

It has recently been argued (for instance by Sanford Goldberg, expanding on earlier work by Tyler Burge) that public linguistic norms are implicated in the epistemology of testimony by way of underwriting the reliability of language comprehension. This paper argues that linguistic normativity, as such, makes no explanatory contribution to the epistemology of testimony, but instead emerges naturally out of a collective effort to maintain language as a reliable medium for the dissemination of knowledge. Consequently, the epistemologies of testimony and language comprehension are deeply intertwined from the start, and there is no room for grounding the one in terms of the other.     

In defence of virtue epistemology

In a number of recent papers Duncan Pritchard argues that virtue epistemology’s central ability condition—one knows that p if and only if one has attained cognitive success (true belief) because of the exercise of intellectual ability—is neither necessary nor sufficient for knowledge. This paper discusses and dismisses a number of responses to Pritchard’s objections and develops a new way of defending virtue epistemology against them.     

In defense of the disjunctive

Are there any disjunctive properties—features of things such as being either red or round, or Nelson Goodman’s infamous example of being grue (i.e. either green if observed on or before 2500 A.D. or blue otherwise)? As esoteric as the question may seem at first, central issues about the metaphysics of properties hinge upon its answer, such as whether reductive views about special science properties can handle the phenomenon of multiple realizability. A familiar argument for a negative answer is that disjunctive properties fail to guarantee that their instances are similar in some genuine respect. In this paper, I respond to a novel, sophisticated version of this argument developed in recent work by Paul Audi. Along the way, I develop two new accounts of what it is for a property to be disjunctive—which rely on important recent work on the nature of essence and analysis—and clarify what one is committed to in believing that there are any disjunctive properties at all.     

In defense of the mirror thesis

In this journal, Luke Russell defends a sophisticated dispositional account of evil personhood according to which a person is evil just in case she is strongly and highly fixedly disposed to perform evil actions in conditions that favour her autonomy. While I am generally sympathetic with this account, I argue that Russell wrongly dismisses the mirror thesis—roughly, the thesis that evil people are the mirror images of the morally best sort of persons—which I have defended elsewhere. Russell’s rejection of the mirror thesis depends upon an independently implausible account of moral sainthood, one that is implausible for reasons that Russell himself suggests in another context. Indeed, an account of moral sainthood that parallels Russell’s account of evil personhood is plausible for the same reasons that his account of evil personhood is, and that suggests that Russell himself is actually committed to the mirror thesis.     

In defense of naturalism

History and the modern sciences are characterized by what is sometimes called a “methodological naturalism” that disregards talk of divine agency. Some religious thinkers argue that this reflects a dogmatic materialism: a non-negotiable and a priori commitment to a materialist metaphysics. In response to this charge, I make a sharp distinction between procedural requirements and metaphysical commitments. The procedural requirement of history and the sciences—that proposed explanations appeal to publicly-accessible bodies of evidence—is non-negotiable, but has no metaphysical implications. The metaphysical commitment is naturalistic, but is both a posteriori and provisional, arising from the fact that for more than 400 years no proposed theistic explanation has been shown capable of meeting the procedural requirement. I argue that there is nothing to prevent religious thinkers from seeking to overturn this metaphysically naturalistic stance. But in order to do so they would need to show that their proposed theistic explanations are the best available explanations of a range of phenomena. Until this has been done, the metaphysical naturalism of history and the sciences remains defensible.
