The paper approves the statement on value-regulatory foundation of science - social science in particular - as mediated by argued scientific discourse. The regulative idea of such a discourse is an ideal communication. The transcendental-argumentative ground of ethics constitutes the normative condition of social theory grounding, meanwhile the intensional content of social theory is derived from critical-reconstructive social sciences. This statement is concretized through application to different theories, especially to those which are associated with bio-technology and genetic technology, preimplantation diagnostics etc. The discoursive foundation of science presupposes, by-turn, an autonomous subject able to bear responsibility for elaboration and realization of such projects, complementing the individual responsibility with common responsibility on the basis of discoursive ethics.
