On Thomas Kuhn 's Reasonable Thoughts

The Rationality of science problem is an important question of scientific philosophy, it is the question which whether the scientific philosophy can be based. From the certain meaning, the problems in philosophy of science can reduce to the rationally of science problem。The theoretical research of rationality of science in Western philosophy of science experiences a long period time of development and many conversions. We must come back to the base; the rationality of science , must commence from science activity oneself ,contacting with rationality of science purpose, and explain the rationality of science by the collectivity of the science practice activity that science common is engaged in, to be used as the new study on rationality of science development and the turns in rationality of science. Science was once considered as developing by the addition of new truths. Science was once considered as developing by the addition of new truths to the stock of old truths,or the increasing approximation of theories to the truth,and the image of it also connected with objectivity,rationality,the truth. However,with the publishment of Tomas Samuel Kuhn's The Structure of Scientific Revolutions,this kind of idea was totally questioned. Kuhn's account of the development of science held that the development of science was not like a linear accumulation and science enjoys periods of stable growth punctuated by revisionary revolutions. Kuhn's scientific revolution view describled the paradigm shift in revolution,which basically belongs to the ideaistic revolution,whether this kind of new revolutionary view is suitable to all scientific revolutions in the science history needs further discuss. But we must say that Kuhn's paradigm theory has its theory rationality,therefore we cannot deny that its value.
