In the theory of knowledge, the four main tools of knowledge used by humans are reason, emotion, language, and perception. Even though these tools are considered to generally enable one to pursue and acquire knowledge, are these four ways of knowing the only ways to acquire knowledge? In recent years, the IB curriculum has included the other four ways of knowing: intuition, imagination, faith and memory, recognizing them as alternative ways of acquiring knowledge. This implies that the knowledge gained through the four methods would be limited, making it necessary to resort to other methods to gain further knowledge. These newly considered knowledge tools are seen as distrusted or invalid means of knowing in certain areas of knowledge. Abraham Maslow's quote implies that we humans are all biased by our backgrounds and tend to come up with solutions to whatever situations our backgrounds suggest to us. If overly familiar methods are not the only tools for acquiring real knowledge, how do other modes of knowing, such as intuition and imagination, play a role in different areas of knowledge? Scientists tend to argue from their common belief that general scientific theories and laws have always been arrived at through rational explanation, thereby ignoring the possibilities of intuitive and imaginary developments. It is commonly believed that intuition or emotions suggest irrationality and that truth and scientific achievements depend on reason alone. Intuition can be defined as the ability to understand something instinctively without the need for conscious reasoning, while imagination can be defined as the ability to form new ideas, images or concepts of external objects not present in the brain. sense. In the fields of natural sciences. ..... middle of article ......since ethics is partly determined by emotional response, most students might be tempted to argue that it is in fact the domain of knowledge that rests most strongly on intuitive thinking. I believe that our moral judgments are based on elaborate processes of socialization by which we gain our moral foundation through the testimonies of the primary sources of authority in our lives, such as our parents, our teachers, our priests, etc. This socialization, when combined with our emotional sensitivity, allows us to be particularly in tune with details, an acuity that we often mistake for our intuition. Therefore, although these other modes of knowing such as intuition, imagination and others, certainly cannot be certified as a justified mode of knowing. knowledge, it still plays an important role in strengthening the quest for knowledge in different fields of knowledge, although to varying degrees.
