In what ways may disagreement aid the pursuit of knowledge in the natural and human sciences?

Extracts from this document...


´╗┐Alix Emden November, 2012 Period 1 Prescribed Title 1. In what ways may disagreement aid the pursuit of knowledge in the natural and human sciences? The word ?disagreement? can mean a lot of different things; for example, it could refer to a slight difference of opinion politely stated, or it could describe a full blown, knock down fist fight, or even a war. Some kinds of disagreement are more productive than others. For example, the Indian political and spiritual leader Mahatma Gandhi said that ?honest disagreement is often a good sign of progress.? On the other hand, the author William Faulkner declared that, ?The last sound on the worthless earth will be two human beings trying to launch a homemade space-ship and already quarreling about where they are going next.? While I do believe that in some cases differences of opinion in the human and natural sciences can lead to further disagreements leading to fewer findings, the majority of the time this is not the case. The basis of disagreements tends can often be traced back to both perception and reason; when people's perception or reason do not match, this often leads to disagreements in everyday life as well as in the sciences. ...read more.


Natural science is the study of natural phenomena of the universe that we live in. This field includes chemistry, biology, physics, among other disciplines. Human science can be defined as the study of people themselves and their behaviors, including matter in subjects including history, anthropology, economics, etc. Because human sciences usually uncover trends rather than absolute facts, much is open for dispute. Human sciences thus provide a fertile breeding ground for disagreements since generally studies take the form of questionnaires and observation rather than incontrovertible numbers or equations which form the basis of natural science. A clear example of how disagreement can advance knowledge in the natural sciences can be found in Einstein's Theory of General Relativity, which is a continuation of Newton's Law of Gravity. Because Einstein questioned Newton's law ? i.e., disagreed with certain aspects of it - he conducted further research and produced a theory that today gives us a better understanding of the universe and interactions of objects even in strong gravitational fields. Einstein's theory starts with Newton's law and makes it applicable in a more sophisticated and complex realm of gravitational fields. ...read more.


There is no amount of scientific evidence that will change their opinion. Similarly, those who accept the theory of evolution are not persuaded by religious doctrine. About the only thing the two sides agree upon is that there must be some theory for how humans came to be on Earth ? beyond that, there is little room for productive disagreement. Indeed, there are two very different kinds of knowledge that are at stake ? one is scientific and one is religious. Disagreements within the two camps might advance knowledge in each, but disagreements between the two aren?t likely to persuade anyone to switch sides. Climate change is an area in between where is there is not only disagreement based on rational science but also disagreement based on other, less quantifiable and provable areas as well. Disagreements as to the cause or extent of human actions in causing climate change may well serve to advance knowledge, but those who flatly deny that climate change is happening at all base their position on emotion rather than reason. As in the case of creationism vs. evolution, disagreement between those two camps is unlikely to advance knowledge overall. When the basis of argument is so fundamentally different ? i.e., emotion rather than reason and evidence ? the prospect of productive disagreement diminishes sharply. ...read more.
