Thinking of this kind requires a deeper critical evaluation of the category of relation. This is a task that cannot be undertaken by the social sciences alone, insofar as the contribution of disciplines such as metaphysics and theology is needed if man's transcendent dignity is to be properly understood. As a spiritual being, the human creature is defined through interpersonal relations. The more authentically he or she lives these relations, the more his or her own personal identity matures. It is not by isolation that man establishes his worth, but by placing himself in relation with others and with God. Hence these relations take on fundamental importance (53).This is the foundation of solidarity - the fact that we are relational creatures, not isolated units. Here we immediately run into a difficulty. Belief in God is not universal among us, and it may be a stumbling block for the secular environmentalists. Yet we can surely agree that we are "relations", even if not all of us locate the source of that relationality in God, in the Trinity of relations we call "Persons". Through biology and physics, I am related to and entangled with everything else on earth, especially the things that live and breathe. But more than that, my own sense of identity is bound up with these natural relations. They are not simply traces of my historical descent or effects of my actions. I have to live these relations (as the Pope says) in order to reach a mature identity.
What does that mean? Surely that in order to be true to myself, I must be receptive to the truth, goodness and beauty that reveals itself to me through these relationships. They impose upon me a responsibility, which I cannot shirk without diminishing my own humanity.
