 Hume famously argues that, in order to clarify any idea, “we need but enquire, from what impression is that supposed idea derived” (EHU, 22). If beauty is a dispositional property, then one arrives at the idea of beauty by associating particular causes with particular effects under specific conditions. In Hume’s terminology, a dispositional idea of beauty would be the idea of a complex relation of cause and effect. It would be a causal principle, and we could not employ the idea prior to formulating such a principle. Yet, once again, Hume denies an implication of the dispositional analysis. The sentiment of approbation is our only source for our idea of beauty, and there are cases where we recognize beauty in advance of any reasoning about the beautiful object (EPM, 173).
