Chapter 10, Footnote #14
Tangle of motive names
Here, as elsewhere, it may be observed, that the same words which are mentioned as names of motives, are also many of them names of passions, appetites, and affections: fictitious entities, which are framed only by considering pleasures or pains in some particular point of view. Some of them are also names of moral qualities. This branch of nomenclature is remarkably entangled: to unravel it completely would take up a whole volume; not a syllable of which would belong properly to the present design.
