Environmental Risk and Social Risk: the Role of the Biotechnological Research in the Construction of the Shareable Security - An instrument for the control of the complexity that is now regaining favour is the redefinition of "rules". The purpose of this redefinition contains a second one in itself: to establish in general if a public Ethic is necessary. The typically polemic expectation, that request of rules emerges on, pertains to the field of both private and public ethic. At the general request of ethically connoted rules, to be meant as an indicative strategy of the action in a horizon of foreseeable risks, corresponds a much widespread awareness that a complex society must rest on the thesis of the Normal Accident, that is, of a normalization of the loss, both human and material. In fact: the normal loss, above all, means a normalization of human loss. The reappearance of the questions that have always followed mankind, now surprise the ethic spring of rules in a phase of disconcerting improbability. The great seasons of moral control of the rapidly increasing social complexity today (for instance Jesuitical casuistry), reintroducing the "moral" fluid medium, show a great weakness. The socio-structural insubstantiality of Ethic shows both the strength and the topicality of the anthropological change we are living, as well as the need to be furnished of instruments of analysis of the human that set aside the scantiness of old mechanical analogies. If the complex society applied only the 40% of the biblical motto "Don’t do onto others what you wouldn’t like to be done to you", this society (ours) couldn’t exist the way it is. Man is no longer the criterion of reference of human actions.
