As a TOK student, I was taught to question everything around me, rather than blindly believing everything what I'm told. Because of this, I have learned to ask for proof for many concepts that my teachers, family members, and friends tell me about. However, this generally relates to subjects taught in the education system, such as mathematics and natural sciences, where evidence and reason are necessary to determine whether an answer or theory is correct/reasonable. In more complex topics like religion, which relies primarily on faith, emotions, and beliefs, evidence plays a very different and often minimal role. This is also often the case with ethics where our morals and our view of others are based on intuition and perception rather than evidence. In the realm of mathematical knowledge, language allows us to generalize words, equations, and ideas to create knowledge. mathematics is universal, rather than dependent on person-to-person opinion, and therefore relies on facts to formulate theories. Mathematics greatly requires the use of reason and logic. Reason is a way of knowing that, through the use of known facts and logic, expands our knowledge. There are two forms of logic in reasoning: deductive and inductive. Induction as a whole is about the human need to look for patterns in observations over time, e.g. Because in the past, 1+2 always equaled 3, we expect that to be the case whenever we add these numbers together. If someone argued that 1+2 equals 6, I would be skeptical and demand proof, because it would go against the ideas instilled in me throughout my studies that 1+2= 3. J 'would need valid evidence to be able to go against my beliefs and against what I would consider...... middle of paper...... it's not really there, affecting not only our perception of world as a whole, but also that of individuals. In conclusion, the extent to which we need evidence to support our beliefs depends on the area of ​​knowledge discussed, as those known for their objectivity and fact-based theories such as science and mathematics require evidence to support in a largely the beliefs of individuals, while those such as Religion and Art require little proof because they are based on our individual sense perception and faith, and therefore because they are not based on reason, but emotion does not need evidence to be justified, or to be justified at all. In these areas of knowledge, it is only to see how valid a belief is that such evidence is necessary. We don't need evidence to support our own beliefs, we need evidence to make our opinions and beliefs valid for others..
