Man is by definition pontifex, "builder of bridges", or "builder of a bridge". For man possesses essentially two dimensions, an outward and an inward; he therefore has the right to both, or else he would not be man, precisely; to speak of a man without surroundings is as contradictory as to speak of a man without a core. On the one hand, we live among the phenomena which surround us and of which we are a part, and on the other hand, our hearts are rooted in God; consequently we must realize as perfect an equilibrium as possible between our life in the world and our life directed toward the Divine. Obviously this second life determines the first and gives it all its meaning; the rights of outwardness depend upon measures which pertain to the inward and which the inward imposes upon us.
