The paper begins with the distinction between different ways of thinking about the posthuman. From the question about the possibility of the formulation of an ethics that goes beyond the precautionary principle the following thesis is defended: posthumanism, in its transhumanist interpretation, is the most consistent standpoint with normative ethics as we know it, if and only if the consequentialist approach characteristic of their supporters is complemented with the deontological one. For this two assumptions are made: the idea of a (...) continuity between humans and posthumans and the right of a human to exercise enhancements on himself/herself that take him/her to a state qualifiable as posthuman, provided that those do not conflict with human dignity.
