Jeremy Bentham's powerful metaphor of Injustice, and her handmaid Falsehood reminds us, if we need reminding, that justice requires not only just laws, and just administration of those laws, but also factual truth - objective factual truth; and that in consequence the very possibility of a just legal system requires that there be objective indications of truth, i.e., objective standards of better or worse evidence... My plan [in this Olin Lecture in Jurisprudence, presented at Notre Dame law School, in October 2004] is to sketch some epistemological themes of mine, and explore their bearing on two familiar, radical epistemological criticisms of our legal system: (i) that an adversarial system is an epistemologically poor way of determining the truth; and (ii) that exclusionary rules of evidence are epistemologically undesirable. Neither criticism, I shall argue, is decisive; both, however, throw harsh light on disturbing aspects of the way our adversarial system actually functions.

We need to find a middle way between the exaggerated deference towards science characteristic of scientism, and the exaggerated suspicion characteristic of anti-scientific attitudes — to acknowledge that science is neither sacred nor a confidence trick. The Critical Commonsensist account of scientific evidence and scientific method offered here corrects the narrowly logical approach of the Old Deferentialists without succumbing to the New Cynics' sociologism or their factitious despair of the epistemic credentials of science

The evidence with respect to scientific claims is like empirical eviderwe generally — only more so: more complex, more dependent on instruments, etc., and usually a shared resource. Warranted scientific claims are always warranted by somebody's, or somebodies', experience, and somebody's or, somebodies', reasoning; so a theory of warrant must begin with the personal and then move to the social before it can get to grips with the impersonal sense in which we speak of a well-warranted claim or ill-founded conjecture

Lewis's account of the role of sensory experience in empirical knowledge rests on the theses: (1) that one's apprehension of what is given in sensory experience is certain; (2) that unless there were such certain apprehension of the given, No knowledge would be possible; (3) that justification of one's other justified empirical beliefs always derives from one's apprehension of the given. I show that all three theses are false. That they are false provides further motivation for the theory of justification I call "foundherentist", Which is fallibilist and permits mutual support (see my "theories of knowledge; an analytic framework", "proceedings of the aristotelian society, Lxxxiii", 1982-3).

Of late, two contrasting departures from the analytic mainstream have become fashionable: the displacement of philosophy by the natural sciences, epitomized by the Churchlands' theme of "neurophilosophy," and the displacement of philosophy by the literary, epitomized by Rorty's theme of philosophy as "just a kind of writing," as "carrying on the conversation" of Western culture. Both are disastrous. My purpose here is to articulate a metaphilosophy which, avoiding both scientism and literary dilettantism, allows a more robustly plausible account of the relation of philosophy to the sciences, and of its relation to literature, than either. In this enterprise, my starting point will be the work of C. S. Peirce. This may come as something as a surprise; for Peirce's avowed aspiration "to rescue the good ship Philosophy for the service of Science from the lawless rovers of the sea of literature" (5.449, 1902), not to mention his unkind remarks about "studying in a literary spirit" (1.33, 1869), might suggest that he is as scientistic, and as hostile to literature, as Rorty is dilettantish, and hostile to science. But, as I shall show, far from being a precursor of those "lawless rovers of the sea of science" among our contemporaries, Peirce points the way to just such a...

The purpose of this paper is, first, to get clear about what credulity is, and why it’s an epistemological vice ; then, to explore the various forms this vice takes, including its perhaps surprising manifestation as a form of scientism ; next, to suggest why credulity poses dangers not only to individuals, but also to society at large—including, specifically, the legal system and the academy ; and, finally, to sketch some ways to curb credulity and foster circumspection in ourselves and others, especially our students. In the process it will take up issues about the nature of belief, the determinants of the quality of evidence, synechism, science, scientism, testimony, expertise, and evidence-sharing as well as questions about the ethics of belief and the demands of education.

My title, “Belief in Naturalism,” signals, not that I adopt naturalism as an article of faith, but that my purpose in this paper is to shed some light on what belief is, on why the concept of belief is needed in epistemology, and how all this relates to debates about epistemological naturalism. After clarifying the many varieties of naturalism, philosophical and other (section 1), and then the various forms of epistemological naturalism specifically (section 2), I offer a theory of belief in which three elements – the behavioral, the neurophysiological, and the socio-historical – interlock (section 3), and apply this theory to resolve some contested questions: about whether animals and pre-linguistic infants have beliefs, about the fallibility of introspection, and about self-deception (section 4).
