While ritual, emotion and reasoning are all significant aspects of human nature, the most nearly unique human characteristic is the ability to associate abstractly and to reason. Curiosity and the urge to solve problems are the emotional hallmarks of our species; and the most characteristically human activities are mathematics, science, technology, music and the arts--a somewhat broader range of subjects than is usually included under the "humanities." Indeed, in its common usage this very word seems to reflect a peculiar narrowness of vision about what is human. Mathematics is as much a "humanity" as poetry.
For what I am suggesting is that concern for the mysterious is at the heart of the humanities, whereas at the heart of the sciences there is a concern with the problematic. That this is a contrast, and not a dichotomy, is seen in the way in which problem-solving has a place in the humanities—though the most significant kind of problem is one that, in Marcel’s language, ‘conceals a mystery’—and in the complementary way in which some scientists, such as Einstein, have spoken of a deepening sense of awe and wonder awakened in them, an awe and wonder in the presence of the universe, that grows through the advance of the sciences, through the growing success in solving problems. But the contrast remains, and since problem-solving can be successful, whereas contemplation of mystery cannot, there cannot be in the humanities any hope for the sort of success the sciences have known. Nor in theology: and especially not in Christian theology whose central mystery is focused in the birth of a child in a stable, and the death of a man on a cross.
