| As it happens, clouds are natural candidates for the explanans in a scientific account. |
| Explanation holds only when the explanans is conceptually related to the explanandum, and this can occur only at the same level of function. |
| Insofar as the explanandum describes an event that occurred during the history of the world, its derivation thereby implies the explanans has empirical content. |
| Both remembering and forgetting are conceived and applied in an almost mechanistic way, as an explanans instead of an explanandum. |
| The discussion thus divides between thermodynamics being an explanandum or explanans. |
| So this argument for perceptualism proposes an explanans to a non-neutral explanandum. |
