Science, technology and ethics: from critical perspective to dialectical perspective.

It has been agreed upon, according to critical perspective, to distinguish the problems raised by scientific issues on the one hand and the problems raised by moral issues on the other. This distinction, at the genesis of theoretical ideology, postulates that experimental science is mere knowledge which, since it has nothing to do with action, cannot raise a moral problem. Yet the use of experimental techniques turns out to be a necessary means, although an insufficient one, to put to the test and to confirm the theoretical hypothesis of science.
