The descent of the Occidental sciences from the heavens to the earth (from 17th-century astronomy to 19th-century biology), and their concentration today, at last, on man himself (in 20th-century anthropology and psychology), mark the path of a prodigious transfer of the focal point of human wonder. Not the animal world, not the plant world, not the miracle of the spheres, but man himself is now the crucial mystery. Man is that alien presence with whom the forces of egoism must come to terms, through whom the ego is to be crucified and resurrected, and in whose image society is to be reformed. Man, understood however not as “I” but as “Thou”: for the ideals and temporal institutions of no tribe, race, continent, social class, or century, can be the measure of the inexhaustible and multifariously wonderful divine existence that is the life in all of us.
