"The ambiguity of progress becomes evident. Without doubt, it offers new possibilities for good, but it also opens up appalling possibilities for evil—possibilities that formerly did not exist. We have all witnessed the way in which progress, in the wrong hands, can become and has indeed become a terrifying progress in evil. If technical progress is not matched by corresponding progress in man's ethical formation, in man's inner growth (cf. Eph 3:16; 2 Cor 4:16), then it is not progress at all, but a threat for man and for the world."
