Lakatos's "hard Core-protection Band" Theory

Lakatos is one of the Four Magnates of philosophy of science,only depending on the book "The Methodology of Scientific research programs".From this we can find the importance of the book.In the book Lakatos discussed his theory of "Scientific research programs" in detail.This theory made a new explanation to the scientific rationality from the perspective of integrity,setting up a new standards to distinguish science and non-science.The theory of "hard core-protective zone" is the core of the"Scientific research programs".Only by further analyzing and clarifying 'hard core-protective zone',can be make a better understanding of the "science research programs".The research also help people make a deeper understanding of the unique contribution in explaining scientific structure and development.This article would discuss mainly from the following three parts:The first part,explored the formation process of "hard core-protective zone"theory and traced back its theoretical origins and direct sources.The ideological origins of the theory could be trace back to Duhem and Quine's holism thought and Hempel's scientific view of holism.Popper and Kuhn made a direct effect to the "hard core-protective zone" theory.From the holism thought,Lakatos had drawn lessons from Popper's philosophy,which had fallen into a difficult situation by mainly emphasizing isolated propositions and had assimilated the rationality of Kuhn's"paradigm" theory.He also put the history of science into the philosophy of science.In the end the "hard core-protective zone" theory was built.The second part,introduced the basis of "hard core-protective zone" theory.Lakatos thought that the basic unit of science should not be the isolate theory that Popper thought,but should be a complete theory system,which has a closely connection and a strict inner structure.He named it "Scientific research programs".The Scientific research programs is consist of four parts,they are "hard core","protective zone","positive heuristics" and "negative heuristics"."Hard core-protective zone" structure is the core of the "Scientific research programs".Others make rules for promoting the structure's dynamic development.The "hard core" and the "protective zone" have different meanings and characteristics,but they are inseparable whole.They make influences to the "Scientific research programs".The third part,the scientific estimate of "hard core-protective zone" theory.This theory is the core of Lakatos' "Scientific research programs".So it is the foundation of understanding his philosophy of science.By understating "hard core-protective zone",can knows the unique and important impact of his philosophy of science well.The establishment of the "hard core-protection zone" theory has made the holistic philosophy of science popularly,it deeply influencing the development of contemporary western philosophy of science,especially the New Historicism's research about the scientific development.And impact of contemporary Western philosophy of the development process in a certain degree.Seeing its positive value as well as its limitations.At last make a comprehensive evaluation by deep analysis.
