The religious doctrine of predestination., page-3

"That explains it perfectly Wheru."
Thank you - if you actually mean it. Well, I'm not sure because I haven't a first clue what your next sentence means.
"You could have chosen to paint them any other color you wished."
PS the analogy only has two colours to make sense. And one of the points of the analogy is that the fruit flies don't get to choose the colours. If they did it would not be predestination.
