Disagreement in the human science field can be shown in the field of history which country disagreeing with each other to cause the war to happen. For example American civil war was happen from one conflict or one disagreement which is about slavery. Northern of United States claim to free and end the slavery in the country however Southern part wanted to continues with the slavery because it will affect their economic in a bad way if the slavery end. The disagreement led further to cause a war against two sides of United States. From historical point of view we can see that disagreements over time over how a war began help to find the true cause of the war. However the knowledge is not certain because of the perception of the viewer who views one country or bias one more than another. There are no absolute truth behind disagreement in human science because history can be record in hatred which causing the truth to be change. On the other hand it may not help to find the absolute truth but from using disagreement help to increase and change the way to approach which can help to discover some knowledge behind.For me the most interesting areas where disagreement aids the pursuit of information are in the areas of knowledge of mathematics and human science. Disagreeing with teacher over either answer was correct or not help to pursuit more knowledge on mathematic than normal because from this I can understand more on how to solve the question by looking at why am I wrong or finding prove to show why I am right. There are a lot of formula and way to solve the question so it is certain by discussing with teacher and sharing our different views, he and I can help each other learn that even though the formula or method isn’t the same but the answer in the end is the same.
