 The idea here is that experiences have to be a certain way in order to justify beliefs. Now, philosophers might accept a particular instance of the E-M Link, but disagree about whether experiences are the way they need to be in order to justify beliefs about the external world. For example, Davidson (1986) and McDowell (1994) agree that experiences justify beliefs about the external world only if experiences have contents that can be assessed for truth. Davidson (1986) argues that experiences do not justify beliefs about the external world on the grounds that they lack truth-assessable contents, whereas McDowell (1994) argues that experiences must have truth-assessable contents given that they justify beliefs about the external world (more on their dispute in  subsection 1.2).
