Scientific Rationality After Heavy Tree

The scientific rational question is a important question of scientific philosophy, it is also the question which whether the scientific philosophy can be based. The logicalism has strengthened the objectivity and the rationality of science, but its standpoint which thinks the objectivity and the rationality of science is guaranteed by the pure and neutral observation fact has the significant flaw; But the historicalism received that all the observations have been controlled by the theory ,this viewpoint completely deny the objectivity and the rationality of science, then stepped onto the relativism path. Shapere develops the good and discards the bad of the logicalism and the historicalism .He proposes its "the information territory" theory. On the one hand this theory thought that any aspect of the science cannot be invariable, but any change of science all has its reasons. "The information territory" theory rerestored the rationality of science. Shapere is a scientific philosopher lived in term of the post-modernism. Facing the scientific philosophy crisis, Shapere's scientific rational theory has the great significance: It pulls again the scientific philosophy returns to the scope of science; It has been clear about the subject for the scientific philosophy; It has realized the denial of denial to scientific philosophy .
