Reductionism or Emergentism?

The goal of science is to explain reality and the world, and the goal of philosophy is also ontology. Philosophical views on scientific opinions and scientific opinions have had a direct influence on the way of worldview and ontology. Since the early twentieth century, the scientific flow of reduction affects logic and philosophy, psychology and sociology, and even theology and religion. On the other hand, the new emergent flow of emergentism in opposition to reductionism flourished in the late twentieth century. The philosophical and analytical validation of these two seemingly contradictory views promotes the levels of scientific methods and approaches, as well as philosophical views, especially philosophies such as the philosophy of religion, the philosophy of psychology, and the philosophy of sociology. Reductionism is trying to coordinate with unity, realize the unity of sciences, eliminate the waste of scientific theories, and provide the possibility of a stronger justification. On the other hand, emergentism involves the hierarchical plurality of the world's creatures. On the other hand, emergentism involves the hierarchical plurality of the world's creatures which causes the classification of science. Each level and class have its lows, rules, and concepts per se. Reductionism is unable to explain the plurality of facts and levels of existence; But emergentism with its theoretical framework explains both the continuum, unity and multiplicity of reality means the hierarchical plurality of reality. the reduction merely is an essential step in understanding and discovering down-up causality that is used as one of the theoretical concepts of emergentism and somewhat explains the cause of the relationship between the layers of existence. But reduction strategy is not successful in recognizing and explaining the existence of layers and classes of science. Reductions with a priority look at reality are subject to selfish judgment and preference, but in emergentism, reality and ontology determine and identify the methodology and epistemology.
