That topic quite good...I wish more people took it seriously...I thought I knew what Europe was!
For me, Europe is a geographical term more than anything else. The excerpt above that starts with "Geographically Europe is a part of..." best describes Europe as such. I cannot agree that Europe means EU. Simply because EU is a union that is constantly expanding and soon most probably non-European countries will be members of it. By non-European I mean countries like Turkey and Russia. Parts of them may be in Europe but this fact does not make them European. So, Europe has political borders and what is inside is Europe!
