"It is often believed that defending the dignity of the human person and his transcendent dimension requires revenge against the reasons for scientific progress, which should therefore be scaled back, slowed down, or even rejected. Little thought is given to the fact that the true subject of technical and scientific endeavour is the human person, and that this endeavour, in addition to expressing a vocation to seek the truth, has a value of promotion for man and for the whole society in which he lives."
