 Eighteenth century theorists, on the other hand, often identified emotions specifically with sense-perceptions. Indeed, Hutcheson multiplied the number of our sense-faculties to accommodate the wide variety of affects he recognizes, while DuBos spoke of the “sixth sense” by which we evaluate poetry and painting. Many philosophers also supposed a haptic aspect to emotions, approaching them as a variety of feeling. Most notably, Hume maintained that a distinctive feature of the passions and sentiments is that they touch, or strike upon the mind more forcibly than other perceptions.
