The first reason for this is that learning about the past brings us all the knowledge and information in the past. Without yesterday, there is no today. A society can develop only when its people inherit and understand the achievements of the precursors because the precursors' achievements were the foundation for everything to develop.. For example, before 1964 there was only black-and-white television but until now there are kinds of colour televisions that are slim and innovative such as LCD TV... The black-and-white television made the basis and gave inventors idea to develop the modern TV nowadays. Consequently our knowledge, success today is the result of constant work of our ancestors before.
Secondly, learning about the past is very essential because it makes us doubt and take consideration into earlier assumptions. For that reason, people will find out mistakes that were made in the past. This will show us which roads not to ever go down again and put human in a right way to develop. Learning about the past is not only learning about the history but also is learning from our and the others' mistakes. By this way of learning, people will become more and more experienced and never make the same mistakes again.
Additionally, if learning about the past has no value, people in the world could speak, could write by themselves without learning from anyone. This is impossible so the value of the past, in this case are the parents, are undeniable.
In a nutshell, the past is always a good...
