The word “emotion” has named a psychological category and a subject for systematic enquiry only since the 19th century. Before then, relevant mental states were categorised variously as “appetites,” “passions,” “affections,” or “sentiments.” The word “emotion” has existed in English since the 17th century, originating as a translation of the French émotion, meaning a physical disturbance. It came into much wider use in 18th-century English, often to refer to mental experiences, becoming a fully fledged theoretical term in the following century, (...) especially through the influence of two Scottish philosopher-physicians, Thomas Brown and Charles Bell. This article relates this intellectual and semantic history to contemporary debates about the usefulness and meaning of “emotion” as a scientific term. (shrink)

Many psychological scientists and behavioral neuroscientists affirm that “emotion” influences thinking, decision-making, actions, social relationships, well-being, and physical and mental health. Yet there is no consensus on a definition of the word “emotion,” and the present data suggest that it cannot be defined as a unitary concept. Theorists and researchers attribute quite different yet heuristic meanings to “emotion.” They show considerable agreement about emotion activation, functions, and regulation. The central goal of this article is to alert researchers, students, and other (...) consumers of “emotion” research to the multiple meanings or aspects that distinguished scientists attribute to ”emotion,” increase appreciation of its interesting and challenging complexity, and sharpen perspectives on “emotion” and the associated body of literature that is of critical significance to science and society.

A definition of emotion common to the affective sciences is an urgent desideratum. Lack of such a definition is a constant source of numerous misunderstandings and a series of mostly fruitless debates. There is little hope that there ever will be agreement on a common definition of emotion, given the sacred traditions of the disciplines involved and the egos of the scholars working in these disciplines. Our aim here is more modest. We propose a list of elements for a working (...) definition of emotion and discuss the justification for the inclusion of elements from our respective perspectives (philosophy and psychology). This working partial definition may at least serve as a litmus test to examine theories of emotion, old and new, across disciplinary boundaries. (shrink)

The central contention of this article is that the classificatory scheme of contemporary affective science, with its traditional categories of emotion, anger, fear, and so on, is no longer suitable to the needs of affective science. Unlike psychological constructionists, who have urged the transition from a discrete to a dimensional approach in the study of affective phenomena, I argue that we can stick to a discrete approach as long as we accept that traditional emotion categories will have to be transformed (...) in order to do any scientific work. I conclude by articulating some general rules for turning traditional emotion categories into suitable scientific tools. (shrink)

This article summarizes the main themes in the book What is Emotion? by Jerome Kagan (Yale University Press, 2007). The issues considered include: (1) the advantage of studying each phase of the cascade that begins with a brain reaction to an incentive and ends with an appraisal of a feeling state and/or a behavioral reaction; (2) distinguishing among appraisals with different origins; (3) replacing the current concern with consequences with more attention to the features of the brain and feeling states; (...) (4) a recognition of the weak relation between the language used to describe a feeling and both the underlying brain profile and a response; and (5) the reasons for variation in the feelings evoked by an incentive and for the appraisals of the feelings.

We conclude that the commentators seem to fundamentally agree on the substance of our proposal of a partial real definition of emotion as a dynamic episode which has to fulfill a certain number of conditions to count as a member of the class. We raise the issue of prescriptive functions of a definition, suggesting parallels to biomedical ontologies. We also clarify the issues of linguistic and cultural relativity and of differences in the nature of individual emotions.

The target articles and commentaries reveal considerable support for the view that the term “emotion” names neither a natural kind nor a coherent psychological category. This brief response revisits a couple of historical points about the meanings of “emotion,” as well as the ancient debate between Stoicism and Christianity.
