Methods of philosophical psychology can be used to analyze the concept of emotion. Distinctions exist between dispositional and occurrent emotional states. Intensionality is neither a necessary nor a sufficient condition for an emotion; thus, emotions can be appraised as reasonable (or unreasonable) and the source of intensionality can be determined. Some emotions have a propositional belief component, while other emotions have a nonpropositional (or attributional) belief component. Important distinctions should be made between the object and cause of emotions, the identity and nature of emotions, and the evidence for an ascription of an emotion and its nature. A cognitive-attitudinal component seems essential and explains both the intentionality and intensionality of emotions. (JAC)
