The Evolvement Of The Modern West Philosophy Of Science Rationality

Mainly using the sight of practice, view of history and the method of unity of history and logic in Marxist, this thesis verifies the evolvement of the modern west philosophy of science rationality systematically and considers the west modern philosophy of science rationality processes three phases: logic rationality, history rationality, historical logic rationality.Logic rationality clears science proposition by logical analysis and makes them faceexperience, that is to say, makes theoretical proposition coincide with observational proposition, its typical character is to regard science as something determined by some universal normative methodology principle which is rebuilt by logic rationality. Logic rationality pursues internal logic of science ^theory at the cost of sacrificing history of science. History rationality emerges dynamic realistic developmental process of science by history, its typical character is to enlarge factors which decide development of science to more broad domain, such as society, psychology ect. History rationality denies universality of science method and objectivity of science theory and leans to relativism strongly. Logic rationality and history rationality give emphasis to logical structure of static transect of science and historical structure of vertical section of science separately. Historical logic rationality would unify that two in order to search logical confirmatory and standardization from historical development, and remove mysticism, mistiness and relativism. The key to grasp historical logic rationality is how to comprehend "history". History is externalobjective cognition object as well as realistic man's activity------man's practice. Moreoverseeing in the last significance, the essence of history is practice. The whole history and tradition are not invariable dead monster, and yet not exemplification of certain changeless laws, but is an object that can be molded renewably and continually. Man's thought and cognition are also validated only through practice, and develop along with the development of practice. Historical logic rationality is in the embryonic stage, but it is new visual angle for us to "see" science, and already has become and will turn into new increasing spot of theory of philosophy of science.
