Despite being an avid fan of Freudian psychology, French psychoanalyst Jacques Lacan upset many traditionalists with his interpretation of the unconscious. Traditional psychoanalysis assumes that the unconscious is not only where our deepest thoughts and feelings reside but also represents a part of ourselves that interacts with the conscious mind.
Lacan argued, though, that it was a big mistake to think we exist absolutely separate from the outside world. We can only make ourselves unique from everything else – “The Other” – by acknowledging its existence. We only come to understand ourselves as distinct from everything around us – “the Other” – by recognizing its presence. We only get a feeling of self if we have an idea about what the Other is saying. We develop an understanding of the Other through the ways in which it communicates with us – signs that Lacan calls its “discourse”. Because our understanding of the other defines us, our inner world – the unconscious – is built on top of the Other. We cannot think and communicate in the languages of the Other, and our unconscious can only speak in these languages.
