What is the defeasibility theory?

According to the defeasibility theory of knowledge, the defect involved can be characterized in terms of evidence that the subject does not possess which overrides, or defeats, the subject’s prima facie justification for belief. This account holds that knowledge is indefeasibly justified true belief.

What is the no defeaters theory?

The view is the most plausible of the fellow well-known theories in epistemic justification. The theory asserts that a person’s belief constitutes knowledge if the belief is true, justified, and has no defeaters. A defeater is defined as a belief that is incompatible with another belief.

How do you make a gettier case?

1. One way to understand Gettier cases involves knowing how to make them.
2. Step 1: select any false proposition, P, for which some believer A has ample justification.
3. Step 2: generalize away from P using a principle of deductive logic to a claim Q that is true but not for the reasons adduced by A in support of P.

How do you solve the Gettier problem?

Gilbert Harman’s solution to the Gettier problem is that reasoning from a false belief precludes knowledge, but Gettier subjects do rea- son from false beliefs, and so do not know. 6 If we distinguish implicit assumptions from beliefs, then we might extend Harman’s proposal to cover false implicit assumptions too.
