[catalogued under 13. Knowledge Criteria / B. Internal Justification / 5. Coherentism / c. Coherentism critique]

Full Idea

The 1st standard objection to coherence is the 'isolation problem', that contingent apparently-empirical beliefs might be justified in the absence of any informational input from the extra-conceptual world they attempt to describe.

Gist of Idea

Coherence seems to justify empirical beliefs about externals when there is no external input

A Reaction

False beliefs can be well justified. In a perfect virtual reality we would believe our experiences precisely because they were so coherent. Messengers from the front line have top priority, but how do you detect infiltrators and liars?
