Hi everyone,
I have been pulling my hair to get a better picture of Habermas. I have difficulty especially with his concept of consensus. According to Habermas practical knowledge (social sciences and/or hermeneutical sciences) is interpretive, socially constructed and usually validated by the ideal consensus reached by competent practitioners of those subject matters. This notion of consensus does not fit in the schema in my mind related to Frankfurt School and critical theory.
To me this “ideal consensus” is too vague and problematic when we think about it in relation to evolution of scientific knowledge. For example, what happens when consensus could be totally wrong, dogmatic, and metaphysical? I think we need more universally valid criteria to validate any knowledge claim.
