 On one version of reliabilism (defended by Ramsey 1931 and Armstrong 1973, among others) one knows p if and only if one arrives at (or sustains) the belief p via a reliable method. Is the reliabilist committed to K? The answer depends on precisely how the relevant notion of reliability is understood. If we understand reliability as tracking theorists do, we will reject closure. But there are other versions of reliabilism which sustain K. For example, the safe indication account is a type of reliabilism. Also, we could say that a true belief p is reliably formed if and only if based on an event that usually would occur only if p (or a p-type belief) were true. Any event that, in this sense, reliably indicates that p is true will also reliably indicate that p’s consequences are true.
