We are living in a time of great dangers and great opportunities for man and the world; a time which is also of great responsibility for us all. During the past century man’s possibilities and his dominion over matter grew by truly unthinkable measures. However, his power to dispose of the world has been such as to allow his capacity for destruction to reach dimensions which at times horrify us. In this connection, the threat of terrorism comes spontaneously to mind, this new war without boundaries or fronts.
The fear that it might soon get a hold of nuclear or biological weapons is not unfounded, and has made it necessary for lawful states to adopt internal security systems similar to those that previously existed only in dictatorships. The feeling remains, nevertheless, that, in reality, all these precautions are not enough, as a global control is neither possible nor desirable.
Less visible, but no less disquieting, are the possibilities of self-manipulation that man has acquired. He has plumbed the depths of being, has deciphered the components of the human being, and is now capable, so to speak, of constructing man himself, who thus no longer comes into the world as a gift of the Creator, but as a product of our action, a product that, therefore, can also be selected according to the exigencies established by ourselves.
Thus, the splendor of being an image of God no longer shines over man, which is what confers on him his dignity and inviolability, and he is left only to the power of his own human capacities. He is no more than the image of man — of what man?
To this are added the great global problems: inequality in the distribution of the goods of the earth, growing poverty, and the more threatening impoverishment and exhaustion of the earth and its resources, hunger, sicknesses that threaten the whole world and the clash of cultures.
All this shows that the growth of our possibilities has not been matched by a comparable development of our moral energy. Moral strength has not grown together with the development of science; rather, it has diminished, because the technical mentality relegates morality to the subjective realm, while we have need, precisely, of a public morality, a morality that is able to respond to the threats that weigh down on the existence of us all. The real and gravest danger in these times lies, precisely, in this imbalance between technical possibilities and moral energy.
