Why couldn’t the world that concerns us – be a fiction? And if somebody asked, “But to a fiction, surely there belongs an author?” – couldn’t one answer simply: why? Doesn’t this “belongs” perhaps belong to the fiction, too?– Nietzsche
That the unified self is largely an illusion is not necessarily a bad thing. The philosopher and cognitive scientist Dan Dennett suggests that it is a convenient fiction. I think he’s right. With it we are able to maintain stories and narratives that help us make sense of the world and our place in it. This is a popular conviction nowadays. As prominent evolutionary psychologist Steven Pinker explains in one of his bestsellers, “each of us feels that there is a single “I” in control. But that is an illusion that the brain works hard to produce.” In fact, without the illusion of selfhood we all might suffer the same fate as Phineas Cage who was, as anyone who has taken an introductory to psychology course might remember, “no longer Cage” after a tragic railroad accident turned his ventromedial prefrontal cortex into a jumbled stew of disconnected neurons.However, according to the British philosopher Julian Baggini in a recent TED lecture the illusion of the self might not be an illusion. The question Baggini asks is if a person should think of himself as a thing that has a bunch of different experiences or as a collection of experiences. This is an important distinction. Baggini explains that, “the fact that we are a very complex collection of things does not mean we are not real.” He invites the audience to consider the metaphor of a waterfall. In many ways a waterfall is like the illusion of the self: is it not permanent, it is always changing and it is different at every single instance. But this doesn’t mean that a waterfall is an illusion or that it is not real. What it means is that we have to understand it as a history, as having certain things that are the same and as a process.
