ABSTRACT
The present chapter is something of an express train ride through the historical and philosophical developments in our understanding of emotion and, to some extent, of cognition. Unlike the slow train, which stops at every station no matter how remote the village or infrequent the passengers, the current journey only pauses at the main towns, concerning itself with the major contributions to our appreciation of cognition and emotion. Inevitably, any definition of what constitutes a major contribution is partly subjective, but we hope that the work reviewed in this chapter represents a consensus of opinion about the central ideas in the literature.
