The naïve realist is generally committed to the following views:6
Among contemporary analytic philosophers who defended direct realism one might refer to, for example, Hilary Putnam,7 John McDowell,89 Galen Strawson,10 John R. Searle,11 and John L. Pollock.12
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".13 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.14
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."15
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.16
Simon Blackburn has argued that whatever positions they may take in books, articles or lectures, naive realism is the view of "philosophers when they are off-duty."17
For a history of direct realist theories, see Direct and indirect realism § History.
Many philosophers claim that it is incompatible to accept naïve realism in the philosophy of perception and scientific realism in the philosophy of science. Scientific realism states that the universe contains just those properties that feature in a scientific description of it, which would mean that secondary qualities like color are not real per se, and that all that exists are certain wavelengths which are reflected by physical objects because of their microscopic surface texture.18
John Locke notably held that the world only contains the primary qualities that feature in a corpuscularian scientific account of the world, and that secondary qualities are in some sense subjective and depend for their existence upon the presence of some perceiver who can observe the objects.19
Naïve realism in philosophy has also inspired work on visual perception in psychology. The leading direct realist theorist in psychology was J. J. Gibson. Other psychologists were heavily influenced by this approach, including William Mace, Claire Michaels,20 Edward S. Reed,21 Robert Shaw, and Michael Turvey. More recently, Carol Fowler has promoted a direct realist approach to speech perception.
