And thirdly the _quality_ of the feeling-tone must be dependent upon, and must be described in terms of the particular kind of coördinated movements suggested or actually carried out. Thus the characters of the feeling-tones for the yellow color above described, for the upright ovals, for the very high tones, for the _Laocoön_ group, and for the _Horse Fair_, are in some respects alike. They have the same general _Gefühlsgrundlage_. The qualities of the feelings for soft deep red, for tactual plush, for low tones, and for the _Angelus_, and, for most subjects, for Venus, would represent another class having the same _Gefühlsgrundlage_. This admits of all the uniqueness specific feelings may have, and at the same time permits of a general classification and description. Some subjects, D and F, for example, may have a feeling whose quality is disgust at some color-form combination. The accompanying sensations may be localized, as they frequently are, in the arms, with impulses to "ward off" the displeasing influence. Subject B often for the same feeling finds sensations of contraction in the throat most prominent, and subject A a stiffening of the features and incipient scowl. The most prominent localization depends upon the habits of the person and the habitual kind of reaction he has acquired and developed during his lifetime. The localization of muscular activity may differ, but _the kind of coördination does not, so far as our introspection shows_. The _regularity_, the _rate_, the _smooth light ease_, or the _heavy, ponderous, deep-seated character_ of the suggested responses indicate some of the terms which would serve as aids in classifying kinds of processes which are physiological conditions for feelings of definite character. Again, feelings of pleasant repose, of depression, or of sudden collapse are still changes also in innervation tonus. These are adaptations for situations just as are the more positive or aggressive kinds illustrated above. Feelings where quick collapse occurs differ in _quality_ from feelings of calm repose. All can be conceived as kinds of adaptations or responses, and clearly correspond to the characters of feeling-tones rather than to any other dimension of feelings or sensations. Certainly the central preparedness for discharge largely determines the feelings. The external excitations are merely the clues. The internal apparatus is set vibrating in a constant manner if no other external or central stimulus is present to demand other adjustments or to intensify the same kind. When such synergetic or antagonistic stimuli are also present the mutual influences of feelings do seem to be, indeed, of great significance. FOOTNOTES: [Footnote 84: As Mach long ago pointed out, _pleasant_ is a vague term and in itself does not serve as a true descriptive term. _Pleasant_ here applies to both feeling for red and for yellow, but something more is needed to distinguish these very different feelings.]
