Why do you think culture, history and customs are important for us? And what would be the ffect if they are eradicated like in BNW?
"Those who forget the lessons of the past are doomed to repeat it."
The world is made up of thousands of different cultures. Each with its own unique history, traditions, beliefs, religions and languages. When we fail to recognize those things, we cannot properly embrace each other as individuals. Our cultures and histories help to define who we are.
Similarly, the blending of these things give birth to new cultures. Take a look around at your surroundings. The music you listen to, your style of dress, the foods that you enjoy eating. It is possible that these things have all been influenced by a culture that is different from your own.
What would the future hold if we suddenly forgot the Holocaust or slavery? Where would our society be if no one wrote down the history of each generation? Not doing so would be equal to pushing future generations back 50 years.
Culture and custom exist in every type of society. These cannot be eradicated. Only these change from society to society, and also within a society over a time.
If you will look back the culture and customs today are not same as what it used to be say fifty years back, And the culture fifty years back was drastically different from that a century ago.
Yes, the culture and customs may be in line with the requirement of its time and place, or it may not be so. Based on this we can call a culture good or bad. However, people have tendency to believe that their own culture is good while those of others is not so good.
I do not wish to advocate a society like the one presented in Brave New World. However, once a society like that exist perhaps their as presented in the book is best for them, and Mustapha Mond gives some very convincing arguments why it is so.
History ofcourse cannot be eradicated. Only people can be unaware of history, And in generral most common people are unaware of most of the history.
