Abstract

This paper analyzes the precautionary principle in the discussion about the ethical status of the human embryo. In this debate, some argue that the mere probability that a human person is involved justifies the duty to refrain from harming to the human embryo; from another point of view, the respect for life and human dignity decreases if the human embryo is not respected; finally, the philosophers Hans Jonas and Jürgen Habermas have proposed the existence of responsibility towards the human life beginning because it is “inviolable” and “unavailable”
