A new argument for evidentialism

When we deliberate whether to believe some proposition, we feel immediately compelled to look for evidence of its truth. Philosophers have labelled this feature of doxastic deliberation 'transparency'. I argue that resolving the disagreement in the ethics of belief between evidentialists and pragmatists turns on the correct explanation of transparency. My hypothesis is that it reflects a conceptual truth about belief: a belief that p is correct if and only if p. This normative truth entails that only evidence can be a reason for belief. Although evidentialism does not follow directly from the mere psychological truth that we cannot believe for non-evidential reasons, it does follow directly from the normative conceptual truth about belief which explains why we cannot do so
