Alfred North Whitehead,
Science and the modern world
(1925)
“ Every scheme for the analysis of nature has to face these two facts, change and endurance. There is yet a third fact to be placed by it, eternality, I will call it. The mountain endures. But when after ages it has been worn away, it has gone. If a replica arises, it is yet a new mountain. A colour is eternal. It haunts time like a spirit. It comes and it goes. But where it comes, it is the same colour. It neither survives nor does it live. It appears when it is wanted. The mountain has to time and space a different relation from that which colour has. ”
