 Now we can sharpen the initial question somewhat: when you ask what happiness is, are you asking what sort of life benefits a person? If so, then your question concerns matters of value, namely what is good for people—the sort of thing that ethical theorists are trained to address. Alternatively, perhaps you simply want to know about the nature of a certain state of mind—happiness in the psychological sense. In this case, some sort of psychological inquiry will be needed, either philosophical or scientific. (Laypersons often have neither sort of question in mind, but are really asking about the sources of happiness. Thus it might be claimed, say, that “happiness is being with good friends.” This is not a view about the nature or definition of happiness, but rather a theory about the sorts of things that tend to make us happy. It leaves unanswered, or takes for granted, the question of just what happiness is, such that friends are a good source of it.)
