The two areas of knowledge I will explore are the arts and the natural sciences. In relation to the question, my initial perspective is that art is a somewhat controversial area of ​​knowledge due to its subjective nature, as it can be difficult to accept something as art in the first place. In contrast, the natural sciences are an area of ​​knowledge that is based on objective truths and so when I initially approached this question, I thought that knowledge can be accepted and then discarded when it is incorrectly disproven in this area of ​​knowledge . First, I would like to use definitional theory to define “knowledge,” which is “facts, information, and skills acquired through experience or education; the theoretical or practical understanding of a topic”. However, using definitional theory to find the meaning of a word can present knowledge problems. This is because, although the definition may seem correct, there are often edge cases and counterexamples one can think of. The main problem in finding the meaning of a word through dictionary definitions is that the definition is given through the use of other words. This leaves us trapped in an endless circle of words, with the same knowledge problems. Definitions between different dictionaries may also differ, which presents yet another knowledge issue that definitions may be subjective. My personal opinion on the theory of definitions is that, while it is advantageous in that it provides an established statement, the knowledge problems it presents are sufficiently substantial that it cannot be answered solely as a way of understanding a word. As for the arts, I have found the problem of defining what art is and what it is not. This in turn leads to the problem… half of the paper… the scraps really depend on the area of ​​knowledge explored in this essay. I have noticed that, for example, in the arts, knowledge is very difficult to accept due to its subjective nature. This can then make it virtually impossible to discard the knowledge. In contrast, within the Natural Sciences I have noticed that although there may be problems with the validity of the information, knowledge is easily accepted once demonstrated. This knowledge is commonly accepted as the law of science, and once this information is disproved, the knowledge is effectively discarded, as it is no longer of any use to people. Therefore I can conclude that we need to look at the area of ​​which knowledge is a part before we can decide whether or not knowledge can be accepted, let alone discarded, due to the subjectivity of the world we live in..
