The problem of easy knowledge arises for theories that have what I call a “basic knowledge structure”. S has basic knowledge of P just in case S knows P prior to knowing that the cognitive source of S's knowing P is reliable.1 Our knowledge has a basic knowledge structure (BKS) just in case we have basic knowledge and we come to know our faculties are reliable on the basis of our basic knowledge. The problem I raised in “Basic Knowledge and (...) the Problem of Easy Knowledge”2 (BKEK) is that once we allow for basic knowledge, we can come to know our faculties are reliable in ways that intuitively are too easy. This raises a serious doubt about whether we had the basic knowledge in the first place. In “Easy Knowledge”, Peter Markie argues that BKS theories do not face any problem concerning easy knowledge.3 I argued that the problem arises in two forms, and Markie takes issue with both. I will argue that Markie's defense of BKS theories fails. (shrink)

The dominant response to this problem of the criterion focuses on the alleged requirement that we need to know a belief source is reliable in order for us to acquire knowledge by that source. Let us call this requirement, “The KR principle”.

Something about this argument sounds funny. As we’ll see, though, it takes some care to identify exactly what Moore has done wrong. Iwill assume that Moore knows premise (2) to be true. One could inquire into how he knows it, and whether that knowledge can be defeated; but Iwon’t. I’ll focus instead on what epistemic relations Moore has to premise (1) and to his conclusion (3). It may matter which epistemic relations we choose to consider. Some philosophers will diagnose Moore’s (...) argument using Contextualist machinery. They’ll say. (shrink)

Many philosophers hold some verion of the doctrine of "basic knowledge". According to this doctrine, it's possible for S to know that p, even if S doesn't know the source of her knowledge that p to be reliable or trustworthy. Stewart Cohen has recently argued that this doctrine confronts the problem of easy knowledge. I defend basic knowledge against this criticism, by providing a contextualist solution to the problem of easy knowledge.

Stewart Cohen has recently presented solutions to two forms of what he calls "The Problem of Easy Knowledge" ("Basic Knowledge and the Problem of Easy Knowledge," Philosophy and Phenomenological Research, LXV, 2, September 2002, pp. 309-329). I offer alternative solutions. Like Cohen's, my solutions allow for basic knowledge. Unlike his, they do not require that we distinguish between animal and reflective knowledge, restrict the applicability of closure under known entailments, or deny the ability of basic knowledge to combine with self-knowledge (...) to provide inductive evidential support. My solution to the closure version of the problem covers a variation on the problem that is immune to Cohen's approach. My response to the bootstrapping version presents reasons to question whether the problem case, as Cohen presents it, is even possible, and, assuming it is, my solution avoids a false implication of Cohen's own. The key to my solutions for both versions is the distinction between an inference's transferring epistemic support, on the one hand, and its not begging the question against skeptics, on the other.

How ought we differentiate the senses? What, say, distinguishes vision from audition? The question comes in two versions. First, there is the traditional problem of individuating the senses in humans. Second, there is also an important question about what sensory modalities we ought to attribute to non-human animals, a version of the question that has been virtually ignored by philosophers. Modality ought to be construed as an “avenue into” an organism for information external to the central nervous system. Six proposed (...) criteria found in the philosophical literature concerning the senses are reviewed. Initially, four criteria—physics, neurobiology, behavior, and evolutionary or developmental dedication—are shown to be individually necessary and jointly sufficient. Next, two criteria—Aristotle's proper objects of sensation criterion and Grice's sensation or qualia criterion—are considered and rejected. One overarching goal here is to show that there is interesting contemporary work left to be done on this ancient philosophical question. (shrink)
