Single Idea 2731

[filed under theme 13. Knowledge Criteria / A. Justification Problems / 2. Justification Challenges / a. Agrippa's trilemma ]

Full Idea

There are four possible kinds of epistemic chain: infinite and unanchored, circular and unanchored, anchored in a belief which is not knowledge, and anchored in a belief which is bedrock knowledge.

Gist of Idea

Justification is either unanchored (infinite or circular), or anchored (in knowledge or non-knowledge)

A Reaction

About right, though I don't think 'chain' is the right word for what is proposed if justification is to be coherent. The justifications float like lilies in the pond of reason, and a Self (Monet?) seems needed to assess the picture


The 10 ideas with the same theme [all three justification structures look hopeless]:

Parts and wholes are either equally knowable or equally unknowable [Plato]
Without distinguishing marks, how do I know what my beliefs are about? [Plato]
Sceptics say justification is an infinite regress, or it stops at the unknowable [Aristotle]
Agrippa's Trilemma: justification is infinite, or ends arbitrarily, or is circular [Agrippa, by Williams,M]
Sceptics say demonstration depends on self-demonstrating things, or indemonstrable things [Diog. Laertius]
There are five possible responses to the problem of infinite regress in justification [Cleve]
Infinitism avoids a regress, circularity or arbitrariness, by saying warrant just increases [Klein,P]
Foundations are justified by non-beliefs, or circularly, or they need no justification [Dancy,J]
Coherentists say that regress problems are assuming 'linear' justification [Williams,M]
Justification is either unanchored (infinite or circular), or anchored (in knowledge or non-knowledge) [Audi,R]
