理查德.罗蒂用“对话”来替代科学方法,以求“新奇”来取代求真知,仅仅以“形而上学的安慰”和“历史的巧合”来解释科学划界的发生动因,试图消解科学划界问题本身,这并不符合科学发生发展的实际情形,不利于对复杂对象世界进行分门别类的探究,而且也会使形形色色的非科学与伪科学混入科学领地,阻碍人们正确认识世界。科学与非科学之间不仅具有相对确定的界限,而且也存在着一些相对确定的划界标准如科学的可检验性标准、科学的简单性标准、科学的逻辑自洽性标准、科学的相容性标准等。科学划界问题是不容消解的,而划界标准又是具体的、历史的,科学划界标准是确定性与不确定性的辩证统一。
Richard Rorty uses “dialogue” instead of scientific methods to seek “novelty” instead of seeking truth, just to explain science by “comforting metaphysics” and “coincidence of history” It is not in conformity with the actual situation of the occurrence and development of science that it is not conducive to the study of the complicated world of objects and to various kinds of non-scientific and pseudo-sciences in scientific fields , Hinder people’s correct understanding of the world. Not only does science and non-science have relatively definite boundaries, but there are also some relatively well-defined demarcation standards such as science’s testability standard, science’s simple standard, science’s logical self-consistency standard and scientific compatibility Sexual standards and so on. The problem of demarcation of science can not be solved, and the demarcation standard is concrete. The historical and scientific demarcation standard is the dialectical unity of certainty and uncertainty.
