Hans Jonas e un’etica “del-non”. Per un’idea pratica di verità

Hans Jonas and Non-Ethics. For a Practical Idea of Truth. According to Hans Jonas, traditional ethics, as it has been understood over the past two millennia, is coming to an end. The assumptions on which normative ethics was based have disappeared, and ethical action no longer possesses the certainty once guaranteed by a shared conception of truth. The advent of the “technological era” has undermined the stable relationship between truth and ethics, theory and practice. Knowledge of truth was once decisive for action, making it possible to establish binding moral norms. With the proliferation of new technologies, however, this relationship is reversed: theory becomes subordinated to action and technique. Technologies impose their own use through their “usability”, operating independently of ethical justification and compelling ethics to adapt. In this context, metaphysical truth itself becomes dangerous, giving rise to an ethics of restraint grounded in uncertainty and in a “Pascalian Anti-Wager”.
