Learning about the past has no value ?
Learning about the past has no value for those of us living in the present?Each of us has a purpose for learning, such as examinations, promotions, business, or as a hobby. It is clear that we don't want to make the same mistakes, which we made before. Also, we want to produce new things so that we can make our lives better. For those purposes, learning about the past is valuable for us.If we don't learn from our mistakes, we will repeat those same mistakes over and over again. To avoid them, we have to observe ourselves from different angles. The best way is to study the past. The past contains many mistakes, which we have previously made. We can learn a lot from them, enough that they won't ever be repeated.On the other hand, some people say that we should discard old things, such as perspectives or the way of thinkings, so that we can make renovation. But can we really make that if we don't know the past? After all new ideas are usually born from old things.Fashion is a good example. Trends of fashion look very new on the surface. But you often see popular fashions from 10 years before returning now. They have a different taste but are basically the same. New fashions are created from old trends.Therefore learning about the past is very valuable for us. By learning, we will acquire wisdom to avoid making the same mistakes again and to make innovations, both privately and publicly.
