SUMMARY:Metaphysics & Logic Seminar Frederick Andersen Title: An Argument Against Justification Holism in the Epistemology of Logic
DESCRIPTION:Abstract: E-sentences (entailment-sentences) are metalinguistic sentences like [A –> B\, A /= B]\, [/= ¬(A & ¬A)]\, and [(A & ¬A) /= B]. This type of sentences is found at the heart of the epistemology of logic as their truth-values tell us what follows from what. Justification holism says that beliefs regarding E-sentences can only be justified in the context of a logical theory\, e.g. classical\, intuitionistic\, paraconsistent etc. Thus\, beliefs concerning E-sentences cannot be atomistically justified as isolated claims about logical consequence\, independently of theory choice. At present there is a developing interest in and endorsement of justification holism due to the revival of a broadly abductivist approach to the epistemology of logic. This paper presents an argument against holism by proving the existence of a foundational E-sentence which is justified independently of theory choice\, i.e. a justificational fixpoint of deductive entailment.
