What Goes Around Comes Aroundwho wrote two thousand years ago that, among other things:
But because throughout the universe from time everlasting countless numbers of [atoms], buffeted and impelled by blows, have shifted in countless ways, experimentation with every kind of movement and combination has at last resulted in arrangements such as those that created and compose our world.
Of course the fact is that from antiquity to today, we have been saying pretty much the same thing, and building the same tower, over and over. For not only did Lucretius get the random movements and combinations part right, he also got the motivation right:
That in no wise the nature of all things
For us was fashioned by a power divine-
So great the faults it stands encumbered with.
Fast forward two thousand years to the brand new idea of evolution:
Odd arrangements and funny solutions are the proof of evolution—paths that a sensible God would never tread but that a natural process, constrained by history, follows perforce. No one understood this better than Darwin. Ernst Mayr has shown how Darwin, in defending evolution, consistently turned to organic parts and geographic distributions that make the least sense. [Stephen J. Gould, 1980]
It has been the same story all along. This world is faulty, therefore no designer ever would have designed it, and therefore it must have evolved spontaneously. These ground rules come from the metaphysics and the details are left for the science.
Religion drives science and it matters.
