Narcissistic personality disorder describes people who demonstrate an exaggerated sense of entitlement, lack empathy and crave admiration. But philosopher Simone de Beauvoir argued that, even if a person isn't a pathological narcissist, narcissism can be a strategy that some people use to help them cope with being undervalued. Through examples such as singer-songwriter Taylor Swift, I show how Beauvoir's philosophy gives us a framework to understand some narcissistic behaviour and possibilities for more authentic ways of being in the world.
