# The Thing Called Emotion **Keywords:** action readiness, emotions, brain state, mental mode, nature of emotions, state capacity **Abstract:** and Keywords The question “What is an emotion?” has haunted philosophers and psychologists for many years. The typical replies proposed to this question reduce emotions to one of their components, such as state, capacity, feeling, or action readiness, or to something else, such as brain state. The perplexity surrounding this issue indicates that simple answers will be of little value. In order to capture the complexities and subtleties of emotions, this article uses two major methods: firstly, describing a typical emotion, and secondly, defining emotions as a mental mode. In different ways, both approaches answer the question “What is an emotion?” By combining the two approaches, one might arrive at a more comprehensive understanding of the nature of emotions. **Authors:** [[Ze'Ev]]
