Transparency of experience

"Transparency thesis" redirects here. The term may also refer to Epistemic transparency.

The transparency of experience says that perception presents blueness as a feature of the sky, not a feature of our experience of the sky.

The transparency of experience is the idea in the philosophy of mind that perception and other conscious experiences are phenomenally transparent. This means that experiences like perception present the properties of objects—like the redness of a tomato—but never the properties of experience itself. In this way, it is said that "we see right through" experience, making it difficult or even impossible for introspection to reveal its intrinsic properties.

Philosophers debate whether experience is fully transparent or whether it is sometimes possible to access the properties of experience. Proposed counterexamples in which features of the experience are said to be directly accessible include itches, pains, emotions and moods. The transparency of experience is most commonly accepted for perceptual experiences, particularly visual perception, but proposed counterexamples also include visual experiences like blurred vision. Philosophers also debate what implications the transparency of experience has for the possibility of introspective knowledge.

The transparency of experience has been interpreted in many ways. Most commonly, it is used to argue for the idea that mental experiences are fundamentally representational, a view called intentionalism or representationalism. This argument is sometimes extended to claim that there are no purely qualitative aspects of experience, or qualia, because all experiences have some representational content. The transparency thesis has also been used to argue for direct realism, disjunctivism, and various other views in the philosophy of mind and philosophy of perception.

The transparency of experience has been traced back to modern philosophy in the writings of Thomas Reid, but it became more prominent in twentieth century philosophy due to famous passages in the works of G. E. Moore and Gilbert Harman.
