Control or liberalization of science or scientific research?Our view is that the study of science must be free and liberal-ized,and the application of science should be ethical.Pure science or basic research must enjoy full freedom,applied science or practical research needs to be careful and prudent,and in the process of transforming applied science into technology and techno-logical practice,it should be subject to strict supervision and due restraints,so as to maintain the necessary tension between diver-sified pursuits or needs.
