Dennis Hackethal criticized idea #3565.
#3565·Dennis HackethalOP, 3 days agoThe myth Popper criticizes, in one sentence:
A rational and fruitful discussion is impossible unless the participants share a common framework of basic assumptions or, at least, unless they have agreed on such a framework for the purpose of the discussion.
By ‘framework’, Popper means an intellectual framework (as opposed to, say, certain attitudes like a desire to find truth).
The myth stems from a “disappointed over-optimism concerning the powers of reason …”. (P. 44)
People think truth should win decisively. But discussions usually don’t lead to such a decisive victory (see #3568). So then people become pessimistic about the fruitfulness of discussions.
