I've listened to Edmonds and Warbuton for a few weeks now - just to explore, and now something new has given me pause from their site. What if our concept of the self is wrong? What if the self is transient and what if this is natural? What if we have no essence but perhaps we keep that idea alive as a social construct or that perhaps the sense of self is something very simple, evolved because we are social animals of a certain sort.
I am keeping this in mind. On balance is the more important idea that we are created by God as purposeful beings and that without purpose, our lives have no meaning. Which is to say that the self exists only as a process of discovery of our purpose. Replace God with Truth if you are so inclined, the spectrum remains if the agency moves slightly. Self is thus the creation of self-discovery of purpose.
