[I argue that a precise definition of emotions is neither necessary nor possible prior to empirical research on emotions. It is not necessary because all that is needed for for fruitful research and successful communication is a working definition of emotions, a description that allows to roughly demarcate the class of emotions. It is not possible because precise emotion definitions are real definitions, empirical claims about the essence of emotions. These claims about the nature of emotion are always formulated against the background of a theory of emotion generation, whose truth they presuppose. The claim that emotions are syndromes of mental and behavioral states is such a theoretical definition of emotion. It is put into question by the finding of low correlations between the proposed syndrome components.]

Magda B. Arnold's theory of emotion is examined from three historical viewpoints. First, I look backward from Arnold to precursors of her theory of emotion in 19th century introspectionist psychology and in classical evolutionary psychology. I try to show that Arnold can be regarded as belonging intellectually to the cognitive tradition of emotion theorising that originated in Brentano and his students, and that she was also significantly influenced by McDougall's evolutionary view of emotion. Second, I look forward from Arnold to the influence she had on Richard S. Lazarus, the theorist who deserves the most credit for popularising the appraisal approach to emotion. Here, I try to document that Lazarus’ theory of the stress emotions preserved most assumptions of Arnold's theory. Finally, I look back at Arnold from today's perspective and address points of success of the appraisal paradigm in emotion psychology, as well as some remaining problems.

ABSTRACT. This chapter presents a reconstruction of Wilhelm Wundt's (1896) three-dimensional theory of emotion from the perspective of the structuralist approach to scientific theories. Wundt's theory, a quantitative theory of the structure of emotional experience, is reconstructed as a small theory-net consisting of the basic theory-element TE(WUNDT) and specializations of this element. The main substantive axiom of TE(WUNDT) postulates that human emotions result from the fusion of a characteristic 'mixture' of six basic forms of feeling: Pleasure, displeasure, excitement, inhibition (tranquillization), tension, and relaxation. A second axiom holds that the basic feeling types are organized into three bipolar dimensions, and the third axiom claims that the basic feelings experienced toward complex objects are a fusion of the corresponding basic feelings directed at the components of the complex objects. Specializations of the theory result from different possible specifications of the central fusion axiom. It appears that only one concept of the theory is T-theoretical, namely the function q which assigns characteristic proportions of basic feelings to the nonbasic emotions. The intended applications of the theory are discussed, and the reconstruction is appraised.
