According to the naïve realist, the objects of perception are not representations of external objects, but are in fact those external objects themselves. The naïve realist is typically also a metaphysical realist, holding that these objects continue to obey the laws of

The indirect realist, by contrast, holds that the objects of perception are simply representations of reality based on sensory inputs, and thus adheres to the primary/secondary quality distinction in ascribing properties to external objects. In addition to indirect realism, naïve realism can also be contrasted with some forms of

, and John L. Pollock. Searle, for instance, disputes the popular assumption that "we can only directly perceive our own subjective experiences, but never objects and states of affairs in the world themselves".John R. Searle, 'Seeing Things as They Are; A Theory of Perception', Oxford University Press. 2015. p.111-114 According to Searle, it has influenced many thinkers to reject direct realism. But Searle contends that the rejection of direct realism is based on a bad argument: the argument from illusion, which in turn relies on vague assumptions on the nature or existence of " sense data". Various sense data theories were deconstructed in 1962 by the British philosopher J. L. Austin in a book titled ''Sense and Sensibilia''. Talk of sense data has largely been replaced today by talk of representational perception in a broader sense, and scientific realists typically take perception to be representational and therefore assume that indirect realism is true. But the assumption is philosophical, and arguably little prevents scientific realists from assuming direct realism to be true. In a blog post on ''"Naive realism and color realism"'', Hilary Putnam sums up with the following words: "Being an apple is not a natural kind in physics, but it is in biology, recall. Being complex and of no interest to fundamental physics isn't a failure to be "real". I think green is as real as applehood." The direct realist claims that the experience of a sunset, for instance, is the real sunset that we directly experience. The indirect realist claims that our relation to reality is indirect, so the experience of a sunset is a subjective representation of what really is radiation as described by physics. But the direct realist does not deny that the sunset is radiation; the experience has a hierarchical structure, and the radiation is part of what amounts to the direct experience.
