Caritas in Veritate §68

⁶⁸ The development of peoples is intimately linked to the development of individuals. The human person by nature is actively involved in his own development. The development in question is not simply the result of natural mechanisms, since as everybody knows, we are all capable of making free and responsible choices. Nor is it merely at the mercy of our caprice, since we all know that we are a gift, not something self-generated. Our freedom is profoundly shaped by our being, and by its limits. No one shapes his own conscience arbitrarily, but we all build our own “I” on the basis of a “self” which is given to us. Not only are other persons outside our control, but each one of us is outside his or her own control. A person's development is compromised, if he claims to be solely responsible for producing what he becomes . By analogy, the development of peoples goes awry if humanity thinks it can re-create itself through the “wonders” of technology, just as economic development is exposed as a destructive sham if it relies on the “wonders” of finance in order to sustain unnatural and consumerist growth. In the face of such Promethean presumption, we must fortify our love for a freedom that is not merely arbitrary, but is rendered truly human by acknowledgment of the good that underlies it. To this end, man needs to look inside himself in order to recognize the fundamental norms of the natural moral law which God has written on our hearts.
