Stewart Cohen argues that basic knowledge is problematic, as it implies that subjects can acquire knowledge or justified beliefs about certain matters in ways that are supposedly too easy. Cohen raises two versions of the problem of easy knowledge, one involving the principle of closure and the other track-record style bootstrapping reasoning. In this paper I confront the problem of easy knowledge from the perspective of epistemological disjunctivism about perception. I argue that disjunctivism can do a better job than dogmatism (...) at responding to the version of the problem involving closure. I also argue that while disjunctivism would permit subjects to bootstrap their way to justified beliefs about the reliability of their perceptual powers, the disjunctivist can distinguish in a principled manner between this sort of bootstrapping and instances of it that we should agree are objectionable.

Offering a solution to the skeptical puzzle is a central aim of Nozick's sensitivity account of knowledge. It is well-known that this account faces serious problems. However, because of its simplicity and its explanatory power, the sensitivity principle has remained attractive and has been subject to numerous modifications, leading to a of sensitivity accounts. I will object to these accounts, arguing that sensitivity accounts of knowledge face two problems. First, they deliver a far too heterogeneous picture of higher-level beliefs about (...) the truth or falsity of one's own beliefs. Second, this problem carries over to bootstrapping and Moorean reasoning. Some beliefs formed via bootstrapping or Moorean reasoning are insensitive, but some closely related beliefs in even stronger propositions are sensitive. These heterogeneous results regarding sensitivity do not fit with our intuitions about bootstrapping and Moorean reasoning. Thus, neither Nozick's sensitivity account of knowledge nor any of its modified versions can provide the basis for an argument that bootstrapping and Moorean reasoning are flawed or for an explanation why they seem to be flawed.

Reliabilists accept the possibility of basic knowledge—knowledge that p in virtue of the reliability of some belief-producing process r without antecedent knowledge that r is reliable. Cohen (Philos Phenomenol Res 65:309–329, 2002 , Philos Phenomenol Res 70:417–430, 2005 ) and Vogel (J Philos 97:602–623, 2000 , J Philos 105:518–539, 2008 ) have argued that one can bootstrap knowledge that r is reliable from basic knowledge. This paper provides a diagnosis of epistemic bootstrapping, and then shows that recent attempts at embracing (...) bootstrapped knowledge are found wanting. Instead it is argued that such arguments are afflicted by a novel kind of generalized epistemic circularity. The ensuing view is defended against various objections, and an explanation of the source of that circularity is offered. (shrink)

Despite its intrinsic plausibility, the sensitivity principle has remained deeply unpopular on the grounds that it violates an even more plausible closure principle. Here we show that sensitivity does not, in general, violate closure. Sensitivity only violates closure when combined with further auxiliary premises—regarding which of an agent’s commitments constitute that agent’s beliefs—which are optional for the sensitivity theorist.

It is widely thought that if knowledge requires sensitivity, knowledge is not closed because sensitivity is not closed. This paper argues that there is no valid argument from sensitivity failure to non-closure of knowledge. Sensitivity does not imply non-closure of knowledge. Closure considerations cannot be used to adjudicate between safety and sensitivity accounts of knowledge.

Reliabilism furnishes an account of basic knowledge that circumvents the problem of the given. However, reliabilism and other epistemological theories that countenance basic knowledge have been criticized for permitting all-too-easy higher-level knowledge. In this paper, I describe the problem of easy knowledge, look briefly at proposed solutions, and then develop my own. I argue that the easy knowledge problem, as it applies to reliabilism, hinges on a false and too crude understanding of ‘reliable’. With a more plausible conception of ‘reliable’, (...) a simple and elegant solution emerges. (shrink)
