 Finally, while EEP tends to have an epistemological internalist flavor, perceptual experience in general is of course linked to the external world. In the case of sensory perception, causal links to the objects of perception play a role in explaining the reliability, and arguably the justificatory status, of perceptual experiences. Emotions don’t seem to be caused by the evaluative properties they represent, however – though if we consider how we go from proximal sensory stimulus to perception of objects, the difference between ordinary perceptual experiences and emotions may not be so large (Milona and Naar 2020). Causal relations may also explain why perceptual experiences have the contents they do.
