How about reading what I actually wrote?
Well, I see someone's been eating his wheaties.
There may very well be a henge constructed somewhere resembling it, but our Stonehenge and the events that somewhat preserved it until 2009 will not occur.
Bull. I know that it's a hypothetical example, but you're vastly overstating your case.
There could very well be a "stonehenge", there could very well be many other henges too, Doggerland and the maritime technology it spawns could lead to an expansion of megalith building societies greater than there was in the OTL.
Because maritime technology so powerfully and inevitably leads to Megalith building, thus explaining the great Viking Pyramids?
Ah, before you get all hot under the collar, relax, I'm just having a bit of fun wit youse. You know the old saying "It's all fun and games when someone loses an eye."
Within the limits of your example, your argument has some resemblance to soundness. It's possible that Doogerland would have repercussions producing no Stonehenge. It's possible that Doggerland would have repercussions producing a bigger Stonehenge. Or a later Stonehenge. Or an earlier Stonehenge.
Or its possible that it wouldn't affect Stonehenge at all, that Doggerland's variable would not be significant compared to the sequence and collection of variables that produce Stonehenge.
Now, it might be that you'll say, even if its the same time, the same place, the same size, the same builders, yadda yadda yadda, but its not really the same henge... I'd just say your mingeing.
What there won't be is our Stonehenge sitting on our Salisbury Plain and preserved in the same manner as has been the case in our timeline.
Mingeing big time.
Doggerland will butterfly away Napoleon. There could very well be a minor European military officer who takes advantage of an revolution in his country to seize power, kick off decades of wars, and establish an empire but saying he'll be Napoleon, he'll be from Corsica, he'll come to power in France, and all the rest is far too deterministic.
Hmmm. No, the revolution will be in France, because that's the place that a confluence of factors will place it. The borders of France might be a bit messier. Might happen a few years earlier or later. May or may not be a corsican, but it will likely be a provincial. He may or may not be Napolean, per se, but he'll be a Napolean analogue in some sufficient respect. There's a niche waiting to be filled, someone will fill it.
Y'see, your mistake, laddy, apart from being a minger, is that you have this idea that every single butterfly produces a hurricane. That just ain't the case.
Evolution and physics exist independently of human beings. We are not responsible for them, we did not invent them, we are only describing processes that existed billions of years before we existed and will exist for billions of years after we are gone.
Yep, but we are subject to them, and we play by these rules. There are all sorts of constraints and drivers.
You're certainly arguing for it.
Nope. I'm arguing for something in between. Absolute determinism is as silly as unhinged butterly worship. Don't be mad at me because I won't play your reindeer games.
And it's been a pleasure to meet you too.
Gee Bill, are we flaming each other? What a waste of time and space. I bear you no particular ill will, and this pint that we are antagonagreeing perhance is trivial in the larger scheme of things. So take no offence, my friend, and should you take offence, then I bid you accept my apology.
I find it kind of ironic. Aleks here posts what seems to be an interesting idea, and one that might be explored in different directions. But all he gets is a bunch of mockingbirds attacking him. Hey, what a way to make a guy feel welcome. What a constructive approach. Doesn't shitting on your fellow human beings and making fun of them with cute pictures really ennoble the whole process. But I suppose that some people are so much better and cooler than other people that its perfectly fine.
Anyway, life is too short, and so's your mother (not to worry, just a little nort shore humour there, lad, no harm meant.

) I'll absent myself from this little toaster, as I've got other things that seem like more fun. Feel free to insult me in my absence, and by all means, hold court.
All the best.
