Before the concept of person: dignity of the embryo as a human being

There is in Bioethics a curious debate around human embryo dignity. Some thinkers, based on the concept of person, defend embryo dignity saying that every human being is a person and is worth of being treated as such. Others, based on the same concept, mean the opposite, introducing a separation between being human and being a person: they defend the dignity of the person, but deny that every human is a person. To think a global bioethics is needed to build a thinking that defends the dignity of every human being, aware of the anthropological diversity, base of a cultural diversity. The authors of this article defend, with many others, the dignity of embryo, not just as a person, but as a human. This position does not deny a duality, but shows that the dignity relies on the concept of human itself because it involves the concept of person.
