Ignorance has nothing to do with bliss

There are people who do not wish to work hard to learn about life and the plannet on which we live. They take the view that the less they know the better. However ignorance has nothing to do with bliss. Achievment by hard work and knowledge gives much more pleasure and happiness than ignorance. If people become ignorant life on earth will become primitive and there will be no advancement in science and technology, something which makes life easier and happier.
