Discursive Democracy in the Transgenerational Context and a Precautionary Turn in Public Reasoning

We should seek to justify, from a moral perspective, policies associated with serious and irreversible risks to the health of human beings, their societies, and the environment for these risks may have great impacts on the autonomy of both existing and future persons. The ideal of discursive democracy provides a way of morally justifying such policies to both existing and future persons. It calls for the inclusive, informed, and uncoerced deliberation toward an agreement of both existing and future persons, which can serve as a justificatory basis for such public policies. This agreement best protects their fundamental interests and basic needs, and garners their general acceptance. It does so by upholding their agency in decision-making processes and, more specifically, by counseling a maxim of precaution in their public reasoning. The aim of this maxim is to protect the social and environmental conditions that will enable members of existing and future generations to review and, if necessary, revise decisions made in the past but that impact upon them in the present. Precautionary public reasoning thus serves to uphold the decisional agency of existing and future persons, which is a necessary condition of their democratic involvement in the policies that affect them and thus of their autonomous existence defined by their conceptions of the good.
