Perhaps the deepest reason we are afraid of death is that we do not know who we are. We believe in a personal, unique, and separate identity; but if we dare to examine it, we find that this identity depends entirely on an endless collection of things to prop it up: our name, our “biography”, our partners, family, home, job, friends, credit card … It is on their fragile and transient support that we rely for our security. So when they are all taken away, will we have any idea of who we really are?
