Enriched Perceptual Content and the Limits of Foundationalism

This paper is about the epistemology of perceptual experiences that have enriched high-level content. Enriched high-level content is content about features other than shape, color, and spatial relations that has a particular etiology. Its etiology runs through states of the agent that process other perceptual content and output sensory content about high-level features. My main contention is that the justification provided by such experiences (for claims about the high-level content) is not foundational justification. This is because the justification provided by such experiences is epistemically dependent on having justification to believe certain claims about the content relevant for enrichment—claims about what I call the corresponding features.
