 The basing relation is most frequently analyzed in terms of a reason’s causing a  belief.[1]  In such analyses, the reason and the belief are understood to be mental states of a person. The cause may be a contributing cause or a sufficient cause. However, the basing relation has also been analyzed as an appropriate counterfactual cause of a belief and also as depending on an appropriate meta-belief to the effect that a reason is a good reason to hold the belief.
