Foucault implies that even when we write a letter for ourselves, we are only showing one side of ourselves and it’s not our true self. It is only one side that comes through for our audience, even if the letter never gets to the recipient. Even if there is no recipient, we never show our true self in what we write. This is similar to Judith Butler in the way that she believes gender is a performative act. Gender to Butler is a social construct and so are the different identities we create for ourselves. We bring out a different version of ourselves depending on who we’re talking to. When we write a letter, we have an audience in mind and even when there is no audience, we think of what our intended audience would be, therefore you’re never going to write something that reflects your true self.
