This paper discusses virtue argumentation theory, as modeled on virtue epistemology. It argues that virtues of argumentation are interesting but parasitic on a more fundamental account of what makes arguments good. -/- *Note: this is an unpublished manuscript presented at the 2013 conference of the Ontario Society for the Study of Argumentation.

“Naturalized epistemology” is a recent attempt to transform the theory of knowledge into a branch of natural science. Traditional epistemologists object to this proposal on the grounds that it eliminates the distinctively philosophical content of epistemology. In this thesis, I argue that traditional philosophers are justified in their reluctance to accept naturalism, but that their ongoing inability to refute it points to deeper problems inherent in traditional epistemology. I establish my thesis first by critiquing three versions of naturalism, showing that (...) each version either fails to implement its objectives consistently or starts from dubious objectives. “Optimistic naturalism” attempts to use naturalistic methods to give positive answers to traditional epistemological questions (such as by affirming that our beliefs can be justified). This fails because the form of traditional questions requires the concept “belief,” a concept that I argue naturalistic methodology cannot countenance (because of the severe constraints of naturalistic semantic theory). “Pessimistic naturalism,” the version advocated by Quine, is more consistent with naturalistic methodology, but fails because hidden behind its conclusions are assumptions (such as the underdetermination thesis) that cannot themselves be naturalized in the full context of scientific evidence. A final attempt to naturalize epistemology, deflationary naturalism, dispenses with traditional questions entirely, urging that the terms “knowledge” and “justification” be taken as mere pragmatic devices whose use can, nevertheless, be studied scientifically. Curiously, this view fails to take account of important facts about the actual use of those terms, as studied by psychologists. In the end, despite problems with each of these versions, traditional philosophers can learn something from their encounter with naturalism. In the course of showing how various naturalistic doctrines cannot themselves be naturalized, I identify the flaws in traditional epistemology (such as its reliance on a priorism, and its resulting inability to articulate a workable empirical foundationalist theory of justification) that make naturalism harder to challenge. These flaws must be corrected if philosophers are to preserve the autonomy of their discipline. (shrink)

Since Ernest Sosa's (1980) seminal paper, a variety of views on the nature of intellectual virtues and their role in one's epistemic theory have emerged. These views, including Sosa's original, largely draw from moral counterparts for their motivation, articulation, and defense. Consider two broad accounts of intellectual virtues: -/- Consequentialist Conception (CC): An intellectual virtue is a stable disposition, ability, or power to reliably acquire epistemic goods (e.g., true belief and knowledge). -/- Aristotelian Conception (AC): An intellectual virtue is a (...) character trait involving an underlying psychological and behavioral structure directed at various epistemic goods.

El articulo analiza dos enfoques coherentistas de lajíístifícación (K. Lehrer y L. Boniour). Ambas versiones se consideran insatisfactorias. En primer lugar, sobrecargan el aparato introspectivo del sujeto cpistémi co, lo cual impide dar cuenta de nuestras intuiciones preanalíticas sobre sujetos "limitados" (niños o animales>. Por otro lado, no consiguen esta blecer un viculo convincente entre justificación ----entendida como cohe í'encia--- y verdad entendida como correspondencia.

I argue that a basic similarity analysis of analogical reasoning handles many apparent cases of visual analogy. I consider how the visual and verbal elements interact in analogical cases. Finally, I offer two analyses of visual elements. One analysis is evidential. The visual elements are evidence for their ver-bal counterparts. One is non-evidential: the visual elements link to verbal elements without providing evi-dence for those elements. The result is to make more room for the logical analysis of visual argumentation.

Scientific antirealists run the argument from underconsideration against scientific realism. I argue that the argument from underconsideration backfires on antirealists’ positive philosophical theories, such as the contextual theory of explanation (van Fraassen, 1980), the English model of rationality (van Fraassen, 1989), the evolutionary explanation of the success of science (Wray, 2008; 2012), and explanatory idealism (Khalifa, 2013). Antirealists strengthen the argument from underconsideration with the pessimistic induction against current scientific theories. In response, I construct a pessimistic induction against antirealists that (...) since antirealists generated problematic philosophical theories in the past, they must be generating problematic philosophical theories now.

Stephen Stich has criticized the possibility of providing a legitimate set of norms for reasoning, since such norms are justified via reference to pretheoretical intuitions. I argue that through a process of perspicuously mapping the belief sphere one can generate a list of intellectual virtues that instrumentally lead to true beliefs. Hence, one does not have to rely on intuitions since the norms of reason are derived from factual claims about the intellectually virtuous agent.
