The Butterfly Effect is the idea that if you went back in time and bumped one Butterfly, the knock on effects would change everything in the future. The future is incredibly sensitive to every action. Daniel Dennett suggests more than that. All you'd have to do is press play again. Life is complicated, uncertain and ambiguous - the role of randomness in determining our path can't be understated. Plans may help us take the next step, but require much more than a pinch of salt. Decisions have unintended consequences. Resilience and custodianship are far more realistic aims than bending the world to our will.
