 However, discriminating Negro folk music into types on the basis of the folk activity that underlies them is not necessarily to exclude the emotive content of the song. In fact, it seems that what is really being discriminated is the active expression of the underlying emotional content, i.e., the activity that is most commonly associated with a particular emotion or mood. And here we see perhaps the most direct effect that Locke's axiology has on his assessment of spirituals discriminating them as he does into types in terms of their feeling-quality, but also linking each form with a set of imperatives in this case, a practical imperative understood by the type of activity that each song is used to motivate.
