The logic of epistemic justification

Area of Science:

• Epistemology
• Philosophy of Logic

Background:

• Epistemic justification theories are typically evaluated using hypothetical cases.
• Assessment via logical principles is less common, with 'closure' principles being a notable exception.

Purpose of the Study:

• To explore the assessment of epistemic justification theories through logical principles.
• To introduce new logical principles relevant to justification.

Main Methods:

• Proposing four new logical principles that plausibly hold for justification.
• Proposing two new logical principles that plausibly do not hold for justification.
• Evaluating different justification theories against these principles.

Main Results:

• Identified several logical principles relevant to epistemic justification.
• Demonstrated the utility of these principles in evaluating justification theories.

Conclusions:

• Tentatively concludes that a 'normic' theory of justification best captures its underlying logic.
• Highlights the importance of logical principles in the epistemology of justification.
