17. Scientific progress is opening to technology - and will open still more - the possibility of delicate interventions, the consequences of which can be very serious, for good as well as for evil. These are achievements of the human spirit which in themselves are admirable. But technology can never be independent of the criterion of morality, since technology exists for man and must respect his finality. Just as there is no right to use nuclear energy for every possible purpose, so there is no right to manipulate human life in every possible direction. Technology must be at the service of man, so as better to ensure the functioning of his normal abilities, to prevent or to cure his illnesses, and to contribute to his better human development. It is true that the evolution of technology makes early abortion more and more easy, but the moral evaluation is in no way modified because of this.
