In Freudian Repression, Michael Billig presents an original reformulation of Freud's concept of repression, showing that in his theory of the unconscious he fails to examine how people actually repress shameful thoughts. Drawing on recent insights from discursive psychology, Billig suggests that in learning to speak we also learn what not to.
First discovered by Sigmund Freud, repression preserves a person’s ego from guilt, fear, disturbing wishes, and other unpleasant sensations. The problem is that even being concealed, they still create anxiety, making a person’s life more difficult (Simply Psychology). Therefore, repression is a defense mechanism that comes at a high cost.
