Indirect realism emphasizes that our perception of the external world is mediated by sensory input, while cognitive realism emphasizes the role of cognitive processes in shaping perception. Epistemological dualism emphasizes that there is a distinction between the external world and our perception of it, which is rooted in the limitations of our sensory and cognitive abilities.
