8 Cultures (Dhaka)
I am basically also interested in Oswald Spenglers Theory of the 8th culturs. He wrote the famous book "Downfall of the western world". 8 th is the european /american culture. 7th was the mexican one...there is also the indian and other one, but no african. He is also decribing the syntoms of rising and falling of a culture, which ae the intension of a specfic culture and their differences. You may find out what is going on by reading his theories. Search on Wikipedia and download his books.
Actually I think it is important to know the differences between cultures and their intension, their opinion about deth or life. Mexican culture for example, can have a very funny view about death and the indian another one. We do not, but may have a good view about life standard.
