Full Idea

Weak alethic relativism holds that while a statement may be true in one framework, it is inexpressible in another. Strong alethic relativism is where a sentence is true relative to one framework, but false relative to another.


'Alethic' means 'concerning truth'

Gist of Idea

To say a relative truth is inexpressible in other frameworks is 'weak', while saying it is false is 'strong'

A Reaction

The weak version will be Kuhn's 'incommensurability' of scientific theories, while the strong version will be full Protagorean relativism, saying all beliefs are true.
