An analysis of the reliability of ideas in the theory of knowledge

Reliabilist Epistemology

But processes used in the past are not mental states concurrent with the target belief, and are not, in general if at alldirectly accessible to an agent now. On this view, a belief can be justified but false which is generally acceptedand, more importantly, S can know that p even when S is susceptible to error because she cannot rule out all the possibilities in which not-p.

He wrote that, because the only method by which we perceive the external world is through our senses, and that, because the senses are not infallible, we should not consider our concept of knowledge infallible.


The landscape next to the road leading through that county is peppered with barn-facades: One potential problem here—and pretty much anywhere that meta-belief is introduced as a necessary condition—is the threat of regress. However, let it be so that Socrates is in fact running in Rome; however, you do not know this.

A stock example is the chicken-sexer, a person who can reliably determine the sex of a young chick, but does not know how she does it. Is vision a process? What this additional truth-link consists in, however, varies widely. According to Gettier, there are certain circumstances in which one does not have knowledge, even when all of the above conditions are met.

The problem of unreliability may be increased also due to the "domino effect" of maintenance-induced failures after repairs. So long as a belief-forming process produces mostly true beliefs, it is a source of justification and knowledge that p, even if the process does not provide the agent with the ability to rule out all counter-possibilities where not-p.

Also, the validation of results is a far more subjective task than for any other type of requirement. Simple K-Reliabilism replaces the justification clause in the traditional tripartite theory with a reliability clause. Now, "justified" is both an epistemic and an evaluative term, and presumably evaluative because epistemic.

Putting the point in a way that perhaps sounds question-begging in favor of sensitivity, one might say that S simply cannot know that radical skeptical hypotheses are false because she would believe, for example, that she is not a BIV even if she were one—she simply cannot tell the difference between BIV worlds and normal worlds.

Knowledge is the most general factive mental state.

The Analysis of Knowledge

Just how high a truth-ratio a process must have to confer justification is left vague, just as the justification concept itself is vague. Sosa explains how safety overcomes the higher-level knowledge and inductive knowledge objections to sensitivity. One may have to decide whether safety obtains by first deciding whether knowledge obtains, rather than vice versa.

Ought we to conclude that his vision is unreliable because it produced only false belief? James Beebe proposes a two-stage approach to solving the generality problem. Thus it is not surprising that many philosophers would reject a theory of justification that did not require an agent at least to be able to give reasons for her belief.

Can we say that we had genuine knowledge of water? Zagzebski suggests that the resultant case will always represent an intuitive lack of knowledge.

Reliability engineering

A number of counterexamples have been produced to this condition see especially DeRose That would be a problematic outcome because the intuition the case is meant to elicit is that Henry does not have knowledge. Does Henry know that the ostended object is a barn? Again, it is assumed as background that a potential attributor constructs lists of belief-forming processes, one for approved process types and one for disapproved types.

These are reliabilist theories of knowledge as opposed to accounts of justification. Examples of reliable processes include: After all, if one has a true belief, one already has what matters to the reliabilist, so how could it matter whether the belief is reliably formed?Dec 08,  · The Reliability Theory of Knowledge and the KK-Principal According to the Reliability Theory of Knowledge, knowing a proposition does not imply that you know that you know it.

In contrast the KK-principal which says that if S knows that P, then S knows that he knows P. Epistemology (/ ɪ ˌ p ɪ s t ɪ ˈ m ɒ l ə dʒ i / (listen); from Greek ἐπιστήμη, epistēmē, meaning 'knowledge', and λόγος, logos, meaning 'logical discourse') is the branch of philosophy concerned with the theory of knowledge.

The analysis of knowledge concerns the attempt to articulate in what exactly this kind of “getting at the truth” consists. Simple K-Reliabilism replaces the justification clause in the traditional tripartite theory with a reliability clause.


knowledge in no way suggests that there are not interesting and informative necessary or. The reliability theme appears in theories of knowledge, of justification, and of evidence. “Reliabilism” is sometimes used broadly to refer to any theory that emphasizes truth-getting or truth indicating properties.

BonJour rejects this maneuver because he thinks the very ideas of knowledge and justification require reflectively accessible reasons.

such as the analysis of knowledge, and skepticism, and argues that externalism fails to take skeptical concerns seriously. The Theory of Knowledge, 3 rd edition (Belmont, CA: Wadsworth).

For any system, one of the first tasks of reliability engineering is to adequately specify the reliability and maintainability requirements allocated from the overall availability needs and, more importantly, derived from proper design failure analysis or preliminary prototype test results.

Clear requirements (able to designed to) should.
