These "concerti" achieve opposition mainly through the polarity of upper part(s) and bass, including such dispositions as two tenors and bass, tenor and two trombones, or two sopranos and two basses.
Such dispositions involve various sensory modalities such as vision and hearing.
As we saw earlier, such dispositions constitute the Mohists' basic conception of knowledge.
Perhaps all such dispositions can be brought under a single heading, which is, most generally, being disposed to act as though P is the case.
For instance, pitches might be either dispositions to cause certain kinds of experiences in suitable subjects, the physical or categorical bases of such dispositions, sensations or projected features of auditory experiences, or simple primitive properties of (actual or edenic) sounds.
Perhaps the more descriptive "thick" ethical terms, such as 'cruel', 'kind', or 'courageous' provide the best examples of terms that possess such dispositions, though these may be evident even when reflecting on "thin" ethical terms, such as 'good' or 'right'right
But for some sentences acquiring such dispositions comes close to mastering their use, because those sentences are almost always true in those cases where observers receive sensory stimulations which dispose them to assent.
Furthermore, it explains why certain dispositions, such as aversion, persist in the mental stream of an individual (because appropriation follows the initial experience of a first moment of aversion), and how it is possible to overcome such dispositions (when appropriation is associated with factors that condition non-aversive states of mind).
Accordingly, while personal corruption may consist in part in the development or suppression of certain dispositions, e.g., in developing the disposition to accept bribes or in suppressing the disposition to refuse them, the development or suppression of such dispositions would not normally constitute the corruption of persons.
Causal-role functions are often defined as a select subset of a trait's actual causal dispositions, and functionalism is often defined as the view that mental states are individuated or classified into types on the basis of such dispositions (see, e.g., Block (1984)).
