Martin Rees, astronomer royal, on forward planning:
I gave a talk at Ely cathedral not long ago. The people who built the cathedral had a limited view of the world. Their world was the fens, and they thought it would end quite soon, but nevertheless built this wonderful structure which is part of our heritage 1,000 years later. And it’s shameful in a way that we, with our longer horizons and greater resources, are reluctant to think 50 years ahead
