↑ See 'Terminology'. See also the entry 'Pleasure' in Stanford Encyclopedia of Philosophy, which begins with this paragraph: "Pleasure, in the inclusive usages most important in moral psychology, ethical theory, and the studies of mind, includes all joy and gladness — all our feeling good, or happy. It is often contrasted with similarly inclusive pain or suffering, which is similarly thought of as including all our feeling bad." It should be mentioned that most encyclopedias, like the one mentioned above and Britannica, do not have an article about suffering and describe pain in the physical sense only.
↑ For instance, Wayne Hudson in Historicizing Suffering, Chapter 14 of Perspectives on Human Suffering (Jeff Malpas and Norelle Lickiss, editors, Springer, 2012): "According to the standard account suffering is a universal human experience described as a negative basic feeling or emotion that involves a subjective character of unpleasantness, aversion, harm or threat of harm to body or mind (Spelman 1997; Cassell 1991)."
