The Precautionary Principle in the Discussion about the Ethical Status of the Human Embryo

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".
