 Other versions of epistemological disjunctivism (not all of which embrace the title) are motivated differently. Some are motivated by the idea that what justifies a perceptual belief that p is the fact that one sees that p (Millar 2011, Byrne 2016), some by the idea that all evidence consists of facts (Williamson 2000), and some by the idea that veridical involves a successful exercise of a capacity while the hallucinatory case does not (Schellenberg 2016).
