In “Remembering, Repeating, and Working Through” (1914), Freud stated that without the concept of resistance there can be no psychoanalysis. As defined by Herbert Strean in this book, resistance is “any action or attitude of the client that impedes the course of therapeutic work” (p. 1). The idea that an impediment is crucial to therapeutic process is a paradox that has resulted in much confusion about resistance. It may even be responsible for the fact that many theorists fail to address this topic in a systematic and comprehensive manner.
