Abstract

Instinct theory parsimoniously clarifies the relationships between emotions, such as fear and anxiety, and perceptions, thoughts, and actions. Its acceptance allows more elegant insights into riddles of obsessions and compulsions. Their relationship to anxiety and dysexecutive function needs to be explained, as does their characteristic egodystonia, while avoiding the pitfalls of cognitivist, empiricist, and teleological thinking.
