Structural Realism Research

Scientific realism holds that the world is an objective reality independent of us,and its existence mode,structure and nature do not depend on the subjective state.The existence and function of the object have nothing to do with the cognition of the object.For objects and objects,no matter in the sense of epistemology or ontology,anti-realists reject their objective reality and deny the truth of scientific theories.The main argumentation of scientific realism is No Miracles argument.it tells me that the success of scientific theory does not depend on Miracles,but because scientific theory always has truth.Pessimistic Induction is the most powerful demonstration strategy for anti-realism to refuted scientific realism.The basis of the demonstration lies in the ontological discontinuity in the scientific change.The description of unobservable entities and their inherent properties in the old theory was abandoned by the new theory,and a new ontological promise was replaced.Cognitive structural realism holds that the mathematical structures throughout the scientific changes not only reflect the structure of the world and mark the structural form of unobservable entities,but also represent the true knowledge about the world.They contain the real relationship between physical entities and reveal the real relationship between the unobservable world.Ontology structural realism holds that if only the second-order formal relations of the world can be known,then it is better to say that only these structural relations exist objectively.There are no entities under structural relationships,no carriers,no individual entities,they are just a utility for us to construct approximate representations of the world and better understand the appearance of the world.The object and object are re-regulated by mathematical structure,which is the ontological world and the ontological world is the mathematicalst ructure.Epistemological structural realism advocates that by constructing ontology and structural knowle dge and accumulating the properties and relations of physical entities we know,real knowledge at any level can be studied.Structural realism effectively deals with the relationship between the change of scientific theory and the growth of ontological content,and explains the continuity of the ontologica l commitment of scientific theory.Forus to understand the change of scientific theory,how scientific theory has truth and how to progress and other issues,provides a new way of defense,bridging the gap caused by the scientific revolution,a strong defense of scientific realism,promote the development of scientific realism.Does structural realism really answer pessimistic induction,does it really solve the problem? By comparing and analyzing various versions of structural realism,we find that th ere are still some deficiencies: it is difficult to distinguish between structure and ontology;The realism of "unstructured" includes the realism of "structural content","theoretical hypothesis","individ ual object" and "other components".Pessimistic induction only shows that the theoretical components a s a whole are wrong and cannot falsify the true knowledge of some areas of the theory.Scientific th eory consists of many parts,such as theoretical principles,auxiliary hypotheses and background know ledge.Science should not be regarded as a consistent theoretical system in logical relations.Science is formed in the process of practical cognition.To solve the truth problem of scientific theory,we must resort to scientific practice.Scientific practice makes scientific theory more and more close to no umenal reality,and the original face of the world will be more and more clear.
