Abstract

In Treatise I.iii.5–10, Hume's claim that association by the relation of cause and effect produces belief is often intertwined – though without his remarking on this fact – with the claim that belief based on causal inference is justified. To explain this, I offer the hypothesis that, in Hume's view, stability plays a double role: whether belief is justified depends upon considerations of stability, and fixity, a species of stability is also essential to belief itself. Hume identifies belief with steadiness, an infixed disposition, rather than vivacity or a lively idea. To establish that a state is a belief is thus to establish that it is stable, other things being equal. In one version of this stability‐based interpretation, the justification of a belief is a matter of its stability in the belief system of a fully reflective person; in a second version, justification is to be assessed in terms of the degree to which the person who holds the belief is reflective.
