There is an idea that cultural resemblance operates by proximity. That, therefore, there may very well be differences between the French and the Germans or Italians, but those pale in comparison to differences between ‘Europeans’ and ‘Asians’.
Now I remember a guy once telling me that he’d been on a trip to Vietnam, and was amazed at how close the two cultures were. This is how he made his assessment: he went to see a French comedy, and people were laughing at all the right places. This would make sense: when the French established colonies in South East Asia, they chose the Vietnamese to rule over others – hence ongoing problems in Cambodia today.
We might make other comparisons. England and Japan: an obsession with rules, people moving away so they won’t come too close to you, high levels of personal repression, except on booze-fuelled evenings to release the tension. Punk teenagers and suited businessmen. Or Northern China may be like southern Italy: Harbin is the closest thing to Naples I’ve seen. People shouting out from their balcony to the street, addressing you spontaneously as you pass. A massive yearning after social contact.
So, rather than Europeans vs Asians, there may be just patterns of internal differences that we can trace on both continents, in an effort to better understand each culture’s own centre of gravity.
