How to device chapters for all classes not missing past, present and future ?

You will all agree with me one big fact that we have learned what has happened in the past and never had the idea of what is going and what is in store for the future. That means by learning the history of past events we completed the studies and even obtained the degrees. But there is every need to device chapters for all classes with past , present and future events on every issue and matter so that inclusive knowledge is imparted and that would have formidable satisfaction of having learned the full. Any comment ?
