Single Idea 8893

[filed under theme 2. Reason / A. Nature of Reason / 6. Coherence ]

Full Idea

The 2nd standard objection to coherence is 'alternative coherent systems' - that there will be indefinitely many possible systems of belief in relation to any given subject area, each as internally coherent as the others.

Gist of Idea

For any given area, there seem to be a huge number of possible coherent systems of beliefs

A Reaction

This seems to imply that you could just invent an explanation, as long as it was coherent, but presumably good coherence is highly sensitive to the actual evidence. Bonjour observes that many of these systems would not survive over time.
