People have long been fascinated, not just by the behaviour of non-human animals, but by the problem of how this behaviour is to be interpreted and explained. This is one of two volumes of original essays on the cognitive and emotional dimensions of non-human minds and the relationship of natural minds to behaviour. The essays also address questions concerning the meaning and significance of consciousness; animal intelligence, awareness and emotions; behavioural plasticity, flexibility and constraints on understanding animal minds; and the structure of explanation in the study of behaviour.
