Language is the brain of the culture. If there is no brain in a body, the body will not be able to do their works. Because they don't know what to do, the brain says them what to do. And after a little time, the body will die.

It is the same with culture-language. If the language dies, the culture dies. What did our elders say?
 "If you want to finish a country, no need to have weapons. It is okey to finish its language."
See? Our language is so important. If there is no language, no culture. Because our language is composed similar to our culture. There are words, idioms about our culture in our language. When our language ends, our culture ends.
I learned lots of things about languages. There are about 20-25 languages in the book, and I had a chance to learn them a bit. There was also a body language, too. The most valuable things in the book were the pages for Turkish I think :) Anyway, the most interesting language was...  Russian! I think because its alphabet seems different to me.
I learned the necessity of the languages from this book in a funny way. It was a bit long, but it was a good book. About animal communication, all of them have a special language. Dogs bark, cats meow, lions roar, snakes hiss... But the difference with human and animal language is; animals are loyal to their languages. They don't change their languages, a dog never prefers meowing to barking. Because they can't. But we the humans, play with the language like a toy. We don't care it. Because we have a mind and we can do what we want.
Okay, no more criticizing us. I am going to talk about animal languages (without criticizing!) now. It is a miracle that all the animals can communicate. Because in human world, we think, then speak. But an animal does this from his heart, not from his brain. Think, dolphins also have names just like us! In fact, animals have brains too-but they don't think. They have no mind, but they have ideas. They use their ideas and their experience. Anyway, that's all from me today. Phew!
