 Treatments of detachability may also have epistemic implications. Some (e.g., John Campbell 2002) have argued that we can’t do justice to the role of sense experience in providing knowledge of the particulars in our surroundings, unless we regard the experience (and even its subjective character) as essentially “object-dependent”. On the other hand, one may wonder if one can do justice to the subjectivity of experience, its perspectival and error-prone nature, while maintaining some form of object-dependence. Consideration of Husserl’s and Merleau-Ponty’s views on perceptual experience, and discussion of contemporary disjunctivism’s treatment of illusion and hallucination, engages with this aspect of the epistemic significance of consciousness.
