Quote from ‘On Topical Geometry, in General (T)’
Qualities […] constitute the first category. A quality of feeling is perfectly simple, in itself; though a quality thought over and thus mixed with other elements, may be compared with others and analyzed. A quality of feeling, in itself, is no object and is attached to no object. It is a mere tone of consciousness. But qualities of feeling may be attached to objects. A quality of feeling, in itself, has no generality; but it is susceptible of generalization without losing its character; and indeed all the qualities of feeling we are able to recognize are more or less generalized. In a mathematical hypothesis the qualities of feeling are so subordinate as to be scarcely noticeable.
