| Objectivity is the goal of human's cognitive practice. The meaning of objectivity has been becoming more and more rich with it's evolution in the history. For science, its objectivity mostly depends on the objectivity of the resource of knowledge as well as its truth. Hereon, according to the frame of semantic analysis demonstrated by Hegel, scientific objectivity can be distinguished into different levels: ontological exteriority, epistemological interiority, and methodological constructiveness.On one hand, centralized by the objective reality of scientific objects, the external scientific objectivity has the property of independence, and is the result of coupling between human and the objective world in human agent's activity. The entities and process, types and constructs, and interpretation sentences and theoretical models, etc, which had been grasped by scientists with the help of intuitive methods and reasonable instruments, are in a way independent of our subjective representation, and bear the objectivity of scientific objects—external objectivity. It is them that constitute the "ontological commitment" of "the scientific community". On the other hand, the external objectivity is realized in the course of interiority of human agent. In modern science, it is "the invariability under transformations" reached in the course of scientists' interiority using the instrument of symmetry that makes science to be of public intelligibility and acceptability. Such acceptability realized in human's active constitution is internal objectivity. Besides, the objectivity of scientific facts and theories is not accomplishment in an action, it receives double methodological construct externally and internally.Based on the clarification of the levels of scientific objectivity, we will find that no matter what level of scientific objectivity has another property—inter-subjectivity, which not only represents scientific objectivity, but also constitutes the limitation of scientific objectivity. |
