Page "Constructivist epistemology" Paragraph 73

Another criticism of constructivism is that it holds that the concepts of two different social formations be entirely different and incommensurate.

This being the case, it is impossible to make comparative judgements about statements made according to each worldview.

This is because the criteria of judgement will themselves have to be based on some worldview or other.

If this is the case, then it brings into question how communication between them about the truth or falsity of any given statement could be established.
