 Another objection to views that posit constitutive links between experiences and beliefs, or between experiential contents and belief contents focuses on primitive creatures that can have experiences, even though they lack the capacity and disposition to form beliefs. Such creatures would seem to be impossible if experiences were constitutively linked to beliefs, as the views discussed here hold. This objection seems to apply to the position that identifies experiences with beliefs about the ways things look (defended by Glüer 2009). In contrast, Glüer’s (2009) view seems immune from the objection that assimilating perceptual experience to belief would entail that subjects of known illusions have contradictory beliefs, and so are irrational. This objection applies to Byrne (2016), who argues that this consequence is plausible.
