I CAME TO BIOCHEMISTRY through chemistry; I came to chemistry, partly by the labyrinthine routes that I have related, and partly through the youthfully romantic notion that the natural sciences had something to do with nature. What I liked about chemistry was its clarity surrounded by darkness; what attracted me, slowly and hesitatingly, to biology was its darkness surrounded by the brightness of the givenness of nature, the holiness of life. And so I have always oscillated between the brightness of reality and the darkness of the unknowable. When Pascal speaks of God in hiding, Deus absconditus, we hear not only the profound existential thinker, but also the great searcher for the reality of the world. I consider this unquenchable resonance as the greatest gift that can be bestowed on a naturalist.
When I look back on my early way in science, on the problems I studied, on the papers I published-and even more, perhaps, on those things that never got into print- I notice a freedom of movement, a lack of guild-imposed narrowness, whose existence in my youth I myself, as I write this, had almost forgotten. The world of science was open before us to a degree that has become inconceivable now, when pages and pages of application papers must justify the plan of investigating, “in depth,” the thirty-fifth foot of the centipede; and one is judged by a jury of one’s peers who are all centipedists or molecular podiatrists. I would say that most of the great scientists of the past could not have arisen, that, in fact, most sciences could not have been founded, if the present utility-drunk and goaldirected
attitude had prevailed.
It is clear that to meditate on the whole of nature, or even on the whole of living nature, is not a road that the natural sciences could long have traveled. This is the way of the poet, the philosopher, the seer. A division of labor had to take place. But the overfragmentation of the vision of nature- or actually its complete disappearance among the majority of scientists-has created a Humpty-Dumpty world that must become increasingly unmanageable as more and tinier pieces are broken off, “for closer inspection,” from the continuum of nature. The consequence of the excessive specialization, which often brings us news that nobody cares to hear, has been that in revisiting a field with which one had been very familiar, say, ten or twenty years earlier, one feels like an intruder in one’s own bathroom, with twenty-four grim experts sharing the tub.
Profounder men than I have failed to diagnose, let alone cure, the disease that has infected us all, and I should say that the ostensible goals have obliterated the real origins of our search. Without a firm center we flounder. The wonderful, inconceivably intricate tapestry is being taken apart strand by strand; each thread is being pulled out, torn up, and analyzed; and at the end even the memory of the design is lost and can no longer be recalled. What has become of an enterprise that started as an exploration of the gesta Dei per naturam?
To follow the acts of God by way of nature is itself an act that can never be completed. Kepler knew this and so did many others, but it is now being forgotten. In general, it is hoped that our road will lead to understanding; mostly it leads only to explanations. The difference between these two terms is also being forgotten: a sleight of hand that I have considered in a recent essay, Einstein is somewhere quoted as having said: “The ununderstandable about nature is that it is understandable.” I think he should have said: “that it is explainable.” These are two very different things, for we understand very little about nature. Even the most exact of our exact sciences float above axiomatic abysses that cannot be explored. It is true, when one’s reason runs a fever, one believes, as in a dream, that this understanding can be grasped; but when one wakes up and the fever is gone, all one is left with are litanies of shallowness.
In our time, so-called laws of nature are being fabricated on the assembly line. But how often is the regularity of these “laws of nature” only the reflection of the regularity of the method employed in their formulation! Lately, many tricks have been discovered about nature; but these tricks seem to have been specially produced by nature for the imbeciles to find out; and there is no Maimonides to guide them out of their confusion. In other words, science is still faced with the age-old predicament, the lack of ultimate verification. It is written in the Analects of Confucius (XII, 19): “The Master said, Heaven does not speak.”
