Thus the moment of linguistic capability (the ability to speak, to distinguish speaking self) is the moment of one’s insertion into a social realm (a world of adults and verbal exchanges). All of us learn to speak in the language and customs of our particular culture; Lacan inverts this to say that we are in fact spoken by the culture itself. Our sense of self is formed through the perception and language of other [the subconscious], and this formation takes place even at the deepest levels of the unconscious. In other words, we can speak only using a language that is foreign to us when we come into the world. Someone else gives us our names, and we learn who we are through the responses of others.
