We think of our eyes as video cameras and our brains as blank tapes to be filled with sensory inputs. Michael Shermer
Our focus is on outputs rather than inputs. Stephen Cambone
Hayek was making us think of the productive process as a process in time, inputs coming before outputs. John Hicks
The world is full of self-organizing systems, systems that form structures not merely in response to inputs from outside but also, indeed primarily, in response to their own internal logic. Global weather is a self-organizing system; so, surely, is the global economy. Paul Krugman
