Abstract

According to reliabilist conceptions of knowledge, knowledge implies reliable true belief. Since reliability is an irreducibly probabilistic notion, one's view of knowledge also depends on one's view of probability. If one believes that all probability is subjective probability, knowledge becomes a relativized concept: knowledge is relative to a given body of beliefs of a given person at a given time. Since such a relativized conception of knowledge is extremely implausible and since reliabilism seems to capture at least part of the truth, one should rather give up a purely subjective view of probability.
