To commence, one of the compelling reasons that justifies the thesis is that our knowledge functions as a shield that protects us from physical or emotional harms. The prime source of knowledge accumulation is by being aware of our past. Practicing such manner would make it possible for us to be aware of the miscalculations performed in the past and stop doing the same. A simple example of it is that we all are aware that a hot food can cause serious damage to our mouth and digestion system. How do we know it? Merely by recalling our child hood experience that putting something hot in the mouth would hurt and burn our tongue.
Another equally important reason, if not more, is that knowing from the past creates a sense of belonging in a person. This sense is very crucial for a society to be prosperous. When members of a society are aware that they have a glorious past history, they won't perform criminal activities. This is very significant to reduce juvenile delinquencies which is an issue that all the nations around the world are struggling with it right now. A research conducted by the MIT University on twenty different nations revealed that the crime rate in societies that members are aware of their past history and have a sense of belonging is very small in comparison with nations that are not aware of their past. This vividly depicts that if we want a safe and sound society, it is imperative to give information about the past to our society members'.
Last but not least, it is also palpable to resolve our world differences and conflicts by becoming aware of the past. For instance, when we study about Africa history, we can clearly understand that they were one united and peaceful nation, unlike now. So, if they had amicable and congenial relation in the past, it is possible to have it right now as well.
