The inspiration for C5 Leadership came from the notion that we need to re-imagining leadership. The need for change has never been more urgent; at the same time we also need to hold what  Richard Feynman has called the "satisfactory philosophy of not knowing." And yet, this notion of embracing doubt as something to be welcomed rather than feared, seems to pose a significant challenge to leadership. Perhaps this is because it is counter intuitive to leaders who are part of a system that values certainty. But nevertheless that is where we are; a place of not knowing. A place where we we must re-imagine our future and  our response to the challenges that we face, rather than relying on the thinking and ways of being that created the challenges in the first place.
