The humanities and natural sciences are considered knowledge by many around the world, as their arguments have convinced people one way or another . While the natural sciences focus on influencing beliefs by showing duplicable evidence through rigorous, standardized methodology, the humanities focus on explaining how things are and how they came to be using logic, reason, and an understanding of human behavior. revolution of the sixteenth century, the Western world became accustomed to accepting knowledge supported by the scientific method, a method standardized throughout the world for the most accurate results. This method allows people to believe that the results obtained from an experiment conducted using the scientific method have been adequately and rigorously tested and must therefore be closest to the truth. This method also allows any experiment to be replicated with the same results, which further solidifies the credibility and position of natural sciences in the world. Another aspect that enables the reliability of natural sciences is current paradigmatic schemes, which distort the truth to remove anomalies. This affects the outcome of the experiments as hypotheses will be shaped to create results that fit the paradigm box. The scientific method varies with slight differences, as there is no exact universal method, however there is a widely accepted basic six-step form. This form has been embellished and improved over time; however the first established form was invented by Ibn al-Haythem, a Muslim physicist, in his Book of Optics. It is as follows:1. Explicit statement of a problem, linked to observation and experimental demonstration2. Testing and/or criticizing a hypothesis ... middle of paper ... results that attempt to be unbiased, and the paradigm box ensures that the experiments conducted fit the thinking pattern of most subjects. people. Human science uses logic and reason to explain how things are that appeal to a person's thinking and understanding. Both are justifiable in their respective circumstances and use ways of knowing that directly influence their methodology. Works Cited Popper, K. R. (1959). The logic of scientific discovery.
