By the seventeenth century, progress was so assured that many Europeans were already entirely oriented toward the future. They were discovering that they had to be ready to scrap the past and start again if they wanted to find the truth. This forward momentum was diametrically opposed to the mythical return to the past which was the foundation of the conservative spirit. The new science had to look forward; this was the way it worked. Once Copernicus’s theory had been proved satisfactorily, it was no longer possible to bring back the Ptolemaic cosmological system. Later, Newton’s own system, though not his methods, would be discounted. Europeans were evolving a new notion of truth. Truth was never absolute, since new discoveries could always replace the old; it had to be demonstrated objectively, and measured by its effectiveness in the practical world. The success of early modern science gave it an authority which was starting to be stronger than that of mythical truth, which met none of these criteria.
This had already been apparent in the Advancement of Learning (1605), written by Francis Bacon (1561–1626), counselor to King James I of England. Bacon insisted that all truth, even the most sacred doctrines of religion, must be subjected to the stringent critical methods of empirical science. If they contradicted proven facts and the evidence of our senses, they must be cast aside. None of the great insights of the past could be permitted to impede our creation of a glorious new future for humanity. The inventions of science would end human misery, Bacon believed, and inaugurate here on earth the millennial kingdom foretold by the prophets. In Bacon’s writings we sense the excitement of the new age. So confident was he, that he could see no conflict between the Bible and science, and, years before the condemnation of Galileo, he demanded complete intellectual liberty for the men of science, whose work was far too important for the human race to be obstructed by simpleminded clergymen. The Advancement of Learning amounted to a declaration of independence on the part of scientific rationalism, which sought emancipation from myth and declared that it alone could give human beings access to truth.
It was an important moment, marking the beginning of science as we know it in the modern West. Hitherto, scientific and rational exploration had always been conducted within a comprehensive mythology which had explained the meaning of these discoveries. The prevailing myth had always controlled these researches and put a brake on their application, as the limitations of conservative society demanded. But by the seventeenth century, European scientists were beginning to liberate themselves from these old constraints. There was no need for them any longer, since the factors that had held agrarian societies back were gradually being overcome. Bacon insisted that science alone was true. His view of science was, admittedly, very different from our own. For Bacon, scientific method consisted chiefly in gathering facts; he did not appreciate the importance of guesswork and hypothesis in scientific research. But Bacon’s definition of truth would be extremely influential, especially in the English-speaking countries. He believed that the only information upon which we could safely rely came from our five senses; anything else was pure fantasy. Philosophy, metaphysics, theology, art, imagination, mysticism, and mythology were all dismissed as irrelevant and superstitious because they could not be verified empirically.
People who subscribed to this wholly rational way of life but who wanted to be religious would have to find new ways of thinking about God and spirituality. We see the death of the mythical approach in the philosophy of the French scientist René Descartes (1596–1650), who was able to speak only in logoi, in rational language. His was a lonely vision. For Descartes, the universe was a lifeless machine, the physical world inert and dead. It could give us no information about the divine. The single living thing in the cosmos was the human mind, which could find certainty merely by turning in upon itself. We could not even be sure that anything besides our own doubts and thoughts existed. Descartes was a devout Catholic; he wanted to satisfy himself about God’s existence, but refused to go back to the primordial, imaginary past of myth and cult. Nor could he rely on the insights of prophets and holy texts. A man of the new age, he would not accept received ideas; the scientist must make his mind a tabula rasa. The sole truth was that supplied by mathematics or by such lapidary propositions as “What’s done cannot be undone,” which was irrefutably correct. Since the way back was closed, Descartes could only inch his way painfully forward.
One evening, sitting beside a wood stove, Descartes evolved the maxim Cogito, ergo sum: “I think, therefore I am.” This, he believed, was self-evident. The one thing of which we could be certain was our mind’s experience of doubt. But this revealed the limitation of the human mind, and the very notion of “limitation” would make no sense if we did not have a prior conception of “perfection.” A perfection that did not exist, however, would be a contradiction in terms. Ergo, the Ultimate Perfection—God—must be a reality.17 This so-called proof is unlikely to satisfy a modern unbeliever, and it shows the impotence of pure reason when faced with such issues. Rational thought is indispensable for our effective functioning in the world. It is at its best when directed toward a pragmatic goal or when, like Descartes, we withdraw from the mundane to consider something as objectively as possible. But when we ask why the world exists (if it does!) or whether life has meaning, reason can make little headway, and the object of our thought itself can become strange to us. Descartes beside his stove, in his cold, empty world, locked into his own uncertainty, and uttering a “proof” which is little more than a mental conundrum, embodies the spiritual dilemma of modern humanity.
Thus, at a time when science and unfettered rationality were forging brilliantly ahead, life was becoming meaningless for an increasing number of people, who, for the first time in human history, were having to live without mythology. The British philosopher Thomas Hobbes (1588–1679) believed that there was a God, but for all practical purposes, God might just as well not exist. Like Luther, Hobbes saw the physical world as empty of the divine. God, Hobbes believed, had revealed himself at the dawn of human history and would do so again at its End. But until that time we had to get on without him, waiting, as it were, in the dark.18 For the French mathematician Blaise Pascal (1623–62), an intensely religious man, the emptiness and the “eternal silence” of the infinite universe opened up by
