“In general, the historical “Western Civilization” comes from the Roman Empire in the west after the split with it’s eastern territories, around 400 AD.”
Indeed - but in this way it is used today only when making the difference between the orthodox church(es) - Romania, Greece, Russia… and the Catholic countries.
“The culture of Western Civilization is supposed to be born from of Hellenistic-Roman origins, and includes most western European thought.”
What means “western European thought” - and is Greece as the “Center of the hellenistic World” not part of the western Culture just because most Greeks ar Orthodox? Or just because that Greece was occupied by the Osman Empire for a while?(Can you hear the difference between Greek Folk music and Turkish Folk music? I can not!)
I think we should realice that through history many things did change. History per se is perpetual change. Yes - Once people did regard the West-Roman-Empire as the West - and the east Roman empire as the East. But do we still (outside church) see this change today? No - at least not really.
Since 1492 did happen quite a lot of things in both parts - The turks were standing at the doors of vienna - occupying a quite big part of eastern and southeastern Europe. The mongolians ran as far as France - Colonists from “Germany” (which did not even exist) from the Rhine-Area did move to Hungary and Transilvania - Colonists went to River Volga. Vikings went from Sweden to colonice northern parts of Russia (In the finnish language Sweden is called Ruotsi (that reminds on Russia!) and even after 1945 we again can see Movements of Populations and Culture. Just visit Cities in the far Russian East as Tomsk or Irkutskt. You will not “feel” the distance to Vienna or Prague even thogh you will find even buddhist Temples along the road there.
The more you know from Europe - the more you will understand that there actually does not exist very much of difference between east and west. Just have a look on Mises himself. Today his home would be in Poland (or maybe Ukraina?). Until 1918 it was Austria. Austria as well as a big deal of eastern Europe were Roman Provinces. But Galizia never was. Are those Jews that fled from Spain throghout Europe to Galizia Europeans? When or how did they became it. Crazy folks as Hitler even said that they are not real human beeings at all. Hitler was “sozialized” in Europe. Was Mises “sozialized” by Europe or by his Jewish “Stetel”. Mises and Hitler actually were sozialiced in the same Country - The Austrian-Hungarian Empire. A multiethincal country that did burst after WW1 in many differnt States. Slavic states as for example Serbia and Tchecoslovakia . Serbia feels close with Russia. The Tchechs do not at all. And we do have Countries in the far west that speak romanic languages. But even Romania speaks a romanic language. But even Serbia and Croatia were Roman provinces. And they do speak slavic languages.
I think the only thin we all have in common in Europe is our weird history. You will not find something like a Link that works as a rational measure to deviede between East and West. Maybe ther just is not such a Thing - any longer. There are just some leftovers. Rudiments of any importance.Sometimes there do apperar People (like Hitler) that insist in making Differences between People. Those people devide by words and expressions.
Even today we still have such people who want to make us believe that we are very different to others. Of course we are different - totally different. And that is the reason why it is just stupid to searc for points of views to make some sort of “invisible” border possible. The “Clash of Civilisations” is just a fraud - because it es hardly possible to define what civilisations really could mean.
OK we had this “Clash of Civilisations” between France and GErmany in many wars - Propaganda on both sides made the other side to something totally strange and different. So different that is is worth fighting it.
To make it short: Give me a Border you want to see - and I will find to you some reasons for just that border. On the ohter hand I could give you even more resons that just that border ist just of any importance.
We peoples should be clever enogh to understand that it is not to our benefit if we let some mighty persons make us belive in the importance of any kind of differences.
Ron Paul found some good words for this in his “Revolution”.
