Knowledge and assertion in “Gettier” cases

Assertion is fundamental to our lives as social and cognitive beings. By asserting, we share knowledge, coordinate behavior, and advance collective inquiry. Accordingly, assertion is of considerable interest to cognitive scientists, social scientists, and philosophers. This paper advances our understanding of the norm of assertion. Prior evidence suggests that knowledge is the norm of assertion, a view known as “the knowledge account.” In its strongest form, the knowledge account says that knowledge is both necessary and sufficient for assertability: you should make an assertion if and only if you know that it is true. The knowledge account has been rejected on the grounds that it conflicts with our ordinary practice of evaluating assertions. This paper reports four experiments that address an important objection of this sort, which focuses on a class of examples known as “Gettier cases.” The results undermine the objection and, in the process, provide further evidence for the knowledge account. The findings also teach some important general lessons about intuitional methodology and the curation of genres of thought experiment.     

How Distinctive Is Philosophers’ Intuition Talk?

The word “intuition” is one frequently used in philosophy. It is often assumed that the way in which philosophers use the word, and others like it, is very distinctive. This claim has been subjected to little empirical scrutiny, however. This article presents the first steps in a qualitative analysis of the use of intuition talk in the academy. It presents the findings of two preliminary empirical studies. The first study examines the use of intuition talk in spoken academic English. The second examines the use of intuition talk in written academic English. It considers what these studies tell us about the distinctiveness of philosophical language and methods and considers some implications for evaluative and ameliorative methodology.     

WHY IS THE HISTORY OF PHILOSOPHY WORTH OUR STUDY?

Abstract: Assume for the sake of argument that doing philosophy is intrinsically valuable, where “doing philosophy” refers to the practice of forging arguments for and against the truth of theses in the domains of metaphysics, epistemology, ethics, and so on. The practice of the history of philosophy is devoted instead to discovering arguments for and against the truth of “authorial” propositions, that is, propositions that state the belief of some historical figure about a philosophical proposition. I explore arguments for thinking that doing history of philosophy is valuable—specifically, valuable in such a way that its value does not reduce to the value of doing philosophy. Most such arguments proffered by historians of philosophy fail, as I show. I then offer a proposal about what makes doing history of philosophy uniquely valuable, but it is one that many historians will not find agreeable.
