Excerpt from Pain and Pleasure In presenting to the public a volume on pain and pleasure as part of a series on the senses, a word of explanation is perhaps necessary as to the precise meaning attached to these terms. It may quite properly be asked how far I mean to identify these terms with sensation, and how far with feeling. Indeed, my whole position in regard to the relation of sensation and feeling naturally comes in question when unpleasantness is included as a variety of pain, and the sensation of tickling is put in the same general class with pleasantness. There is probably no more disputed ground in psychology than that which relates to the above point, and none in which more different shades of opinion have authoritative support. Speaking personally, I find it impossible to dispute the fact of a distinct difference between the sensation of pain and the feeling of unpleasantness, but the points of similarity seem far more significant than the points of difference.
