Why does Nozick rely on closest possible world in his tracking theory?

What is Nozick’s tracking theory?

The core idea of Robert Nozick’s truth tracking theory is that if one has a tendency to believe something when it’s true, and not believe it when it’s false, then one knows it. (Nagel, p. 62).

What is the tracking theory of knowledge?

Tracking theorists hypothesize that in order to qualify as knowledge, a true belief must track the relevant fact-the belief must depend in an appropriate way upon the fact that accounts for its truth.

What are Nozick’s four conditions for knowledge?

Nozick’s Conditions on Knowledge:

(1) P is true. (2) S believes that p. (3) If p were not true, S would not believe that p. (4) If p were true, S would believe that p.

What is knowledge according to Nozick?

Conditions for knowledge. Our task is to formulate further conditions to go alongside. (I) p is true (2) S believes that p. We would like each condition to be necessary for knowledge, so any case that fails to satisfy it will not be an instance of knowledge.

What is knowledge according to Reliabilism?

Ramsey (1931) is often credited with the first articulation of a reliabilist account of knowledge. He claimed that knowledge is true belief that is certain and obtained by a reliable process. That idea lay more-or-less dormant until the 1960s, when reliabilist theories emerged in earnest.

Why is reliabilism an Externalist theory of knowledge?

Because reliabilism bases epistemic evaluations upon factors that hold true of the knower, but which they need not have psychologically available to them in forming and/or retaining a belief, reliabilism is an externalist theory.

Which is the better theory of justification Evidentialism or reliabilism and why?

Evidentialism is therefore a thesis about which beliefs are justified and which are not. For philosophers Richard Feldman and Earl Conee, evidentialism is the strongest argument for justification because it identifies the primary notion of epistemic justification.

What is reliabilism a level philosophy?

Reliabilism. Reliabilism says James knows that P if: P is true. James believes that P. James’s belief that P is caused by a reliable method.

What is the difference between Internalism and Externalism?

Internalism is the thesis that no fact about the world can provide reasons for action independently of desires and beliefs. Externalism is the thesis that reasons are to be identified with objective features of the world.

Why is belief not necessary for knowledge?

Belief is necessary but not sufficient for knowledge. We are all sometimes mistaken in what we believe; in other words, while some of our beliefs are true, others are false. As we try to acquire knowledge, then, we are trying to increase our stock of true beliefs (while simultaneously minimizing our false beliefs).

What is the generality problem for reliabilism?

The Generality Problem for Reliabilism

Argues that reliability approaches to justification are severely defective. They fail even to assert a necessary and sufficient condition for justification, much less a correct condition, if they do not identify the bearers of reliability.

How can knowledge be reliable?

The core idea of Goldman’s original reliabilist theory of knowledge is that a true belief attains the status of knowledge just when it is produced by a reliable cognitive mechanism, where reliability is understood to consist in a tendency to produce true beliefs (Goldman 1976).

What is the generality problem for meaning?

The generality problem for reliabilism is the problem of determining, for any given belief, which belief-forming process type is relevant for justification-determining purposes.

What is justification of knowledge?

Epistemic justification (from episteme, the Greek word for knowledge) is the right standing of a person’s beliefs with respect to knowledge, though there is some disagreement about what that means precisely. Some argue that right standing refers to whether the beliefs are more likely to be true.

What is an Epistemically basic belief?

Epistemic beliefs are beliefs whose content contains an epistemic concept such as knowledge or justification, whereas a non-epistemic belief does not contain an epistemic concept. The belief that there is a red circle before me is not an epistemic belief because its content does not contain any epistemic concepts.

Does knowledge equal justified true belief?

The JTB account holds that knowledge is equivalent to justified true belief; if all three conditions (justification, truth, and belief) are met of a given claim, then we have knowledge of that claim.

What is justification and how does it function in the theory of knowledge?

Justification and knowledge

“Justification” involves the reasons why someone holds a belief that one should hold based on one’s current evidence. Justification is a property of beliefs insofar as they are held blamelessly. In other words, a justified belief is a belief that a person is entitled to hold.
