Although there is evidence supporting that they are inseparable, is one more dominant than the other?. Personal knowledge (as stated previously) is the basis of all scientific discoveries. It’s proven that several scientific discoveries were based on someone else’s personal knowledge. Experiments and tests can also rely entirely on personal knowledge. So is it safe to say that personal truths can be universal and are deemed of higher importance than shared knowledge? Karl Popper, a philosopher of natural science states that “All knowledge is theory-laden. Thus deduced through a prior understanding of other theories and concepts.”. According to Popper, human growth’s source comes from our problems and the self-determination to solve them. These attempts involve the formulation of theories which exist from earlier theories. Hence, Popper emphasizes the importance of the independent creative imagination to helps us go beyond existing knowledge to produce these new, innovative theories. He then went on and created the falsification theory which in other words is to criticize the theory. He believed that criticism lies at the heart of rational thought, therefore the method being about critical discussion and reflection. The resulting general position of the method is called “critical rationalism”. We can’t prove anything with full certainty in the natural world, so the purpose is not to show that things are true but what is false. Shared and personal knowledge are slightly different when looking into human sciences. The concept is about not only to explain human behavior but to also understand it. As psychologists on the outside of the situation, capable of understanding its key ideas?. We can base this upon the sociology theory which are these propositions that determine our understanding of the social world. Sociology was first developed during the Industrial Revolution in response to the suffering of the people and theories were created to explain what was happening.Emile Durkheim and Max Weber, arguably the most famous figures in human sciences both shared had different ideas revolving around the approaches to human sciences. Durkheim was often addressed as the father of sociology. He believed that social structures serve a function, maintain order and stability in society. Durkheim stated that the whole notion influenced the sudden shift in behavior. His research methods involved analyzing facts and figures to arrive at his own conclusions. He used a positivist approach, focusing mainly on the generalization of (mostly quantified) data. Patterns of data are observed therefore making this inductive reasoning. He favored an outside method of remaining detached. Sense perception is used in the form of careful observation to attempt to understand the way people act with one another and the environment.
