You say: "Yet, Habermas’ focus on intersubjective agreement rather than correspondence with an objective reality distinguishes his epistemology from strict fallibilism, which often ties knowledge to empirical testability". But didn't he distinguish between objective, subjective and intersubjective epistemological domains. And in the objective didn't he tie knowledge to empirical testability?

You’re absolutely right to point out that Jürgen Habermas distinguishes between different epistemological domains—objective, subjective, and intersubjective—in his theory of communicative action, and this nuance is critical to understanding his epistemology. Let me clarify and address your question directly.

Habermas does indeed differentiate three "worlds" in his framework. To address your specific point: Yes, in the objective domain, Habermas does tie knowledge to empirical testability, which aligns with fallibilism. For example, scientific claims about the natural world are subject to empirical scrutiny and revision, much like in Popper’s fallibilist framework. However, Habermas’ broader epistemology is not limited to this domain. His focus on communicative rationality and the intersubjective domain—where knowledge and norms are justified through dialogue and consensus—sets his approach apart from strict fallibilism, which typically prioritizes empirical testability across all knowledge claims.

In the intersubjective domain, Habermas is less concerned with correspondence to an objective reality (as in empirical science) and more with achieving rational agreement among participants. This makes his epistemology distinct from classical fallibilism, which doesn’t typically account for normative or social knowledge in the same way. So, while Habermas’ approach to the objective world is fallibilist in its empirical orientation, his overall epistemology transcends strict fallibilism by incorporating intersubjective and normative dimensions that prioritize rational discourse over empirical falsification alone.

Does this clarify the distinction, or would you like me to dig deeper into any specific aspect of his framework?

If he is a fallibilist in one domain then what is he in the others?

Jürgen Habermas’ epistemology, as expressed through his theory of communicative action, varies across the three domains he identifies—objective, subjective, and intersubjective (social). As you noted, his approach in the objective domain aligns with fallibilism due to its emphasis on empirical testability and revisability of truth claims. Below, I’ll outline his epistemological stance in each domain to clarify what he is in the subjective and intersubjective domains, while keeping it concise and directly addressing your question.

Objective Domain (External World):

Epistemological Stance: Fallibilist Explanation: In the objective domain, knowledge claims are about factual states of affairs (e.g., scientific propositions). These claims are tied to truth and subject to empirical testing and falsification, much like in classical fallibilism (e.g., Popper). Habermas accepts that such claims are provisional, open to revision based on new evidence, and grounded in empirical validation. This makes his stance in this domain explicitly fallibilist.

Subjective Domain (Individual Experience):

Epistemological Stance: Expressivist or Non-Cognitive Explanation: The subjective domain concerns personal experiences, emotions, and intentions, where claims are evaluated based on sincerity or authenticity (e.g., “I feel sad”). Habermas does not treat these as knowledge claims in the same way as objective or intersubjective claims, as they are not subject to empirical testing or rational consensus. Instead, their validity depends on the speaker’s truthfulness, which is assessed through the coherence of their expressions and actions. This aligns with an expressivist or non-cognitive epistemology, where claims are not “true” or “false” in a propositional sense but are valid if sincerely expressed. This stance is not fallibilist, as it doesn’t involve revisability through evidence or argument in the same way.

Intersubjective Domain (Social World):

Epistemological Stance: Communicative Rationalist Explanation: In the intersubjective domain, knowledge claims pertain to shared norms, values, and social practices, evaluated based on normative rightness. Validity is established through rational discourse in the “ideal speech situation,” where participants seek consensus through argumentation under conditions of equality and freedom from coercion. While these claims are revisable (similar to fallibilism), their justification relies on intersubjective agreement rather than empirical testability. Habermas’ focus on rational consensus through dialogue makes his epistemology here communicative rationalist, distinct from fallibilism’s emphasis on empirical falsification. The provisional nature of consensus (open to further discourse) shares some fallibilist traits, but the method of validation—discursive agreement—sets it apart.

Summary: Habermas is a fallibilist in the objective domain, where empirical testability governs truth claims. In the subjective domain, he adopts an expressivist or non-cognitive stance, focusing on sincerity rather than propositional knowledge. In the intersubjective domain, he is a communicative rationalist, prioritizing rational consensus through discourse over empirical falsification, though with a revisable quality akin to fallibilism.
