| Feyerabend advocated the principle of pluralism methodology of"the anything goes"publicly, no clear boundaries between science and no science and relativism of incommensurab- ility, therefore, he was an anarchist in the field of the epistemology and philosophy of science. However, theory of the philosophy of science of Lakatos who is pasted labeling of the fine falsificationism theory contained the same spirit of epistemology of anarchism. Lakatos'the principle of tolerance led to blurring of boundary line about progressive and deteriorative research program, mistiness of boundary line of reasonable and unreasonable research program. His standard of demarcation led to obscuring the boundary line of science and non science. His principle of theory of error made boundary line of right and wrong theory, ture and false theory blurred. Thus Lakatos'view and Feyerabend's thinking have a similarity essentially, only difference was that Feyerabend was an open anarchist, and Lakatos was a disguised anarchist who was pasted labeling of the fine falsificationism. |
