Countertransference is an important part of the analytical process. It is concerned with the analyst's emotional response to the patient. As such, it can be a particularly difficult aspect of the analytical setting and especially so because of the threat of possible sexual involvement with the patient. At present there is little available on this difficult topic. Jungian analyst David Sedgwick tackles the subject bravely and shows how to use the countertransference in a positive way. The result is one of the finest Jungian clinical texts of recent years.
