Psychoanalysis is interested in anger from early on; in fact, it’s right there on the ground floor of psychoanalysis. Sigmund Freud and Josef Breuer, a general physician in Vienna, collaborated on a series of experiments in psychotherapy which would give rise to what we call psychoanalysis. In 1893, they write what they call a preliminary communication about their findings. They have an idea that the traumas that trouble our mental lives are caused by injuries: psychic injuries, or psychic foreign bodies that intrude. Often, this leads to a kind of lodged anger at the centre of the self.
One of the examples they give is of a man who has been humiliated in the street by his boss, who has attacked him with a stick. This employee finds himself unable, for whatever reason, to retaliate or to remonstrate with his boss, so he has to silently swallow his humiliation. Freud very briefly presents this case, but he says that under hypnosis, this man reproduces a second scene, in which he goes to court against his boss and actually fails to get satisfaction. So, the humiliation is doubled.
We’re dealing with a traumatised man in whom a feeling of humiliation has entrenched itself. This particular sense of injury, to the dignity of the human being at the very core – a violation at the most raw and vulnerable place – is the source of anger.
