Defining omniscience as an unalterable future has debatable validity / utility.And omniscience means "knows everything" and there is no "unless something he doesn't know happens" exception.
I appreciate Dawkins' insight, & I'm glad you've disclosed it here. And while I may accept it as Dawkins seems to present it, my reservation is
the premise is omniscient AND omnipotent.
CERTAINLY that requires some accommodation of definitions / capabilities.
But my inclination about a hypothetical about a hypothetical is to not veto the premise, although I have zero problem with making the reservation/s clear before proceeding.
Mutually exclusive? Let's go with yes. BUT
if the premise is both, that's the premise.
I don't know enough about Dawkins to be certain. Benefit of doubt,
Dawkins may have been attempting a broader point here which I enthusiastically if not vehemently endorse.
And if I'm reading these tea leaves correctly, that doesn't undermine God, it indicts religion.
If that approximates where we are here, I appreciate the insights.
On Topology:
Not sure if this qualifies, but a ~few years ago some stock market traders contended with the reality that:
- trades are made by computer.
- $Millions can we made or lost in a few seconds, depending on the speed with which the trading algorithm is executed.
Knowing this some enterprising investors located their computer as physically close to the stock market's computer as they could,
so that their communication cable was shorter, thus quicker than all the others.
Reportedly
though this imparted only a tiny fraction of a second advantage, it was enough to enable them to sell high, immediately before
a specific stock value plummeted.
The report I reviewed on this indicated this is legal.
Not sure if that's topology or not.
