The revolution brought about a transformation in the way Europeans conceptualized the universe. New discoveries about the nature of the universe and the structure of nature undermined old models and raised fundamental questions concerning the source of authority for ultimate truth. The Scientific Revolution also led to a series of changes in the structure of European thought, which replaced religious models with secular ones, and caused a serious spiritual crisis. The nature of this crisis and the impact of modern science are examined in order to gain a better understanding of their influence on modern world views as well as contemporary attitudes to scientific and ethical problems. Key words: scepticism, scientific method, secularization, religion 1. Introduction Natural calamities and fatal accidents seem to have an uncanny way of shattering our confidence in our ability to understand natural phenomena. However, whenever they occur, we often hire experts to search for their cause. Facts are gathered and examined in order to formulate hypotheses as to why these tragedies happen, and tests are carried out in order to prove various theories. Although the families of victims grieve over the death of their loved ones, and seek solace by attributing their loss to some sort of divine plan, their belief in the power of science to find answers never completely wanes. The reason for this tendency is that people expect scientific experts to find the answers to their questions and to explain phenomena. Furthermore, it seems that modern man relies on science to explain the world and himself; and he resorts to it to make sense of the inscrutable events that occur in his life. This paper will attempt to explain how this tendency came about, and will discuss its overall effects on contemporary thinking. 16 Thomas HARRAN'Hidenori ERA 2. Background of the Scientific Revolution The origins of the shift in world views from a religious one based on the authority of the Church to a secular one based on empiricism date back to the 16th and 17th centuries - a phase in European history known as the Scientific Revolution. During this time profound changes took place not only in natural science and technology, but also in man's way of perceiving the world. This revolution was really an intellectual one in that the growing forces of science brought about a series of gradual changes in the structure of European thought: systematic doubt, empirical and sensory verification, abstraction of human knowledge into separate sciences, and the mind-set that the universe can function like a machine. Developments in science during this period gave rise to the secularization of the human mind, and played a vital a role in undermining old traditions and ways oflife. In a sense, these changes were the seeds that grew into the secular mind-set ofmodern man. Perceptions of events are sometimes shaped by the way in which historians interpret them. The Scientific Revolution is a phase in history that is thought to have come about suddenly.' Some historians have tended to interpret this phase as if it occurred explosively and suddenly. The public mind is led to believe that somehow science did not exist before the 16th and 17th centuries, and that the world of the Middle Ages was completely immersed in darkness and superstition. As Richard Hooker points out in one of his essays, it was Roger Bacon, the great medieval scientist, who really invented the empirical methods that would form the cornerstone of empirical science of the 16th and 17th centuries. His trial and error method of finding knowledge and of cataloging all the circumstances of trials formed the foundation of modern scientific research. Although Europeans slowly began to change their methods of science in the late Middle Ages, the core of thinking remained medieval; that is, they continued to believe that the center of truth and experience was in God. Furthermore, medieval scientists depended on church doctrine and Aristotelianism, which is also known as Scholasticism. J.M Roberts (1990:628) argues that `medieval science rested on assumptions which were untested, in part because the means of testing them could not be grasped, in part because the wish to test them did not exist'. Medieval scientific thought would not change until there was a new conception of the universe based on natural Iaws, and a willingness to trust human petception and the material world. AStudy of the Scientific Revolution 17 3. Systematic doubt and the role of mathematics When the Treaty of Westphalia (1648) was signed, the bloody religious battles, known collectively as the Thirty Years's War, came to an end. This treaty maybe seen as turning point in European history because statesmen began to face the reality that fighting and killing was not necessarily an effective way to establish God's truth. The religious wars contributed to the undermining of church dogma. Thinkers gradually began to abandon the old authorities on truth, and started to turn to the principles of doubt to anive at the truth. Descartes's work Discours epitomizes this change. In his work, he teaches that the pursuit of knowledge must begin with systematic doubt. The attitude of doubting assumptions is one of the cornerstones of modern science, and skepticism is essential to science because no new theory can be accepted blindly. For these reasons, experiments are usually canied out by scientists to prove or disprove the validity of theories that are advanced. In addition to the secularization of the human mind, another change that emerged from the 17th century was the importance of the application of mathematics to the science of mechanics. It is likely that the increasing use of firearms perhaps brought about the need to gain a better understanding of the nature of the motion of projectiles. In fact, the problem of the flight of projectiles led Galileo to study the gravitational fall ofbodies. The law which states that all bodies, regardless oftheir weight, fall through the same distance in the same time was proved by devising a graduated inclined plane and then measuring the time taken by the bodies to roll down given lengths of the plane. The significance of this experiment is that it allows us to gain an understanding of the methodology he used in his research. By "geometrising" the problem and using mathematics, he was also able to show that a body remains in the same state of uniform motion so long as it is not acted on by a force. Moreover, he believed the `book' of the universe must be written in mathematical language. Butterfield (1997:100) points out that `without the achievements of mathematics, the scientific revolution would have been impossible'. In a sense, it was Galileo who laid the groundwork for a mechanical view of the universe by means ofmathematising problems. (Butterfield, 1957:84) 4. The mechanistic view of the universe The developments in early modern science culminated with Iasaac Newton's Principia. In this work, he describes his model of a mechanical universe. The 18 Thomas HARRAN•Hidenori ERA Principia was of great importance because it dealt a serious blow to traditional ways of thinking. In this work, Newton put forth the following theories : ') the universe can be explained mathematically. 2) it operates rationally and predictably according to mathematical descriptions.3) religion is not necessary to explain the physical phenomena of the universe, and4) all planets and objects move because of a physical attraction between them. The changes in intellectual thought in the 17th century cannot be attributed solely to the influence of Newton's work. Butterfield (1957:131) suggests that the growing familiarity with clocks and machines at the time may have been a factor in bringing about a gradual change in the way the universe was conceived. Furthermore, he points out that a reaction against superstition may also have played a role in creating the mechanistic view of the universe. As result of increasing superstition and religious wars, a desire to prove that there was indeed a divine order to the universe arose in people's minds. Without regularity in the workings of the universe, Christian miracles would have no meaning and nature would seem magical. In fact, he suggests that `the intellectual leaders' desire to show that the universe operated like a clockwork had religious motivations'. There was yearning to prove divine order and perfection by demonstrating that the universe ran with the same regularity as a clock. This aspiration is reflected in Newton's ideas. In his work, he describes the universe as a huge machine of objects moving and colliding into each other and each functioning according its own laws like the balls on a billiard table. However, God in Newton's system is still the intelligent and omnipresent governor. It was Newton's clockwork vision that became the dominant model of the universe for the next several centuries. 5. The Influence of Protestantism The mechanistic view of the universe slowly changed the way western man conceptualized the universe. The belief that God was like a watchmaker who built the mechanism ofthe universe and left it to run on its own is known as Deism. The Deists believed that the phenomena of the universe are rational and mechanistic and can be explained without reliance on religion or authority. Hooker (1996:11) suggests that `all modern knowledge and the majority of our experience is ultimately derived from this principle'. The emergence of the secularization of the human mind and the mechanistic view of the universe cannot be attributed solely to the scientific achievements of this period. There are a number of other important factors that contributed to the AStudy of the Scientific Revolution 19 religious and intellectual transformation of Europe in the 16th and 17th centuries. The turmoil of religious wars sapped the intellectual authority of the Roman Catholic Church. The protestant reformers at the time advocated that people should reject the authority of catholic priests and each seek a personal spiritual truth. Likewise, the early scientists rejected scholasticism and began to search for truth in empirical experience. Hodges (2000:8) argues that protestants began to Iook to the natural world for answers about life's deeper questions. He suggests that study of the physical world became worthy because many protestants came to believe that the natural world provided evidence of God's ways. Further factors that may have contributed to the change in intellectual thought were the Calvinist attacks on the traditional concept of the hierarchy ofbeings. Mason 1962: (181-182) notes: The removal of the angelic beings from the government of the universe in Calvinist theology was indeed an attack upon the idea that the world was peopled by a graded scale of beings, each possessing a decree of power which decreased as the scale was descended. He explains that according to Calvinist theology God governed directly as an absolute ruler by means of decrees decided at the very beginning of creation. He implies that these decrees are really the laws of nature, and that the belief that God ruled in this way is actually the doctrine of predestination. Mason points out a similarity between the attacks by the Calvinists on traditional theology and those made by the scientists on traditional cosmology. He argues that their attacks prepared the way for a new mechanical-theological world view. 6. Changes in political power Changes in political power also provide evidence to suggest that the shift from a religious world-view to secular a one was not only due to the effects of science. The long religious wars led to the eventual decline of the political power of the feudal baron and the collapse of the intellectual authority ofthe church. As a result, a new system of power -- a national state ruled by a powerful king -- gradually replaced feudal law and church law. At the same time, urban centers such as London, Paris, Antwerp, Milan, Strasbourg and Geneva emerged with a new political hierarchy based on the power of money. In fact, urban leaders and kings sometimes joined forces against the feudal lords and church bishops. These shifts in power produced a political climate congenial to the process of secularization and urbanization. 20 Thomas HARRAN•Hidenori ERA 7. The influence of the printed word The rise of the printed word was another significant factor in bringing about changes in thought at this time. The dissemination of knowledge enabled writers to influence people's religious allegiances, and the increase in printed bibles gave individuals the freedom to read and interpret the scriptures in their own way. The growth of the publishing industry played a vital role in promoting vernacular languages and in disseminating scientific knowledge. The exchange of scientific information was made possible by the printed word and, as a result, allowed scholars to collect and compare data from different sources related to one subject matter. Furthermore, the importance of collecting data and comparing texts became the principal methods of reporting research results. Boorstin (1983:386) points out that the exchange of information promoted the growth of scientific societies throughout Europe and ultimately led to the concept of science as a collective body of systematized knowledge. Lastly, the waning of the Church's authority in scientific matters was eroded by the infiuence of the printed word; without books the seeds of scepticism could never have been planted, and the search for truth without the approval of the Church might have been impossible. The proliferation of travel books also had a profound effect on the outlook ofmany Europeans. As they become more familiar with distant lands, the outlook of Europeans slowly changed. Butterfield (1957: 195) writes: Western Europe was now coming to be familiar with the widespread existence of peoples who had never heard of ancient Greece or of Christianity. When these are taken into a larger survey, the European outlook came to be envisioned not as universal ...... but somewhat as a regional affair. He implies here that the byproduct of this exposure was that Europeans come to regard their culture and religion with a degree ofrelativity. This change in attitude towards other peoples played an important role in creating new visions of the world. The ability to regard one's own culture and traditions with a degree ofrelativity was a contributing factor in fostering new attitudes towards peoples in the New World. Boorstin (1983:628) points out that Columbus's descriptions of the people he encountered in his travels reflected a change in the way Europeans viewed the people of the New World. His reports describe the Indians as people who had "handsome bodies and very good faces". Furthermore, one ofhis letters reveals that he considered them to be a congenial and gratefu1 people. Although his reports of the people he encountered may not seem extremely important, they do provide AStudy of the Scientific Revolution 21 evidence of an incipient shift in attitude towards peoples who had once been viewed as less than human. Likewise, the French naturalist Alcide d'Orbigny, who spent almost eight years exploring South America, declared in his work "L'homme Americain"in 1839 that among all men there is only one `species'. This new outlook emerged because of European's gradual familiarity with different peoples around the world. The knowledge gained as result of their discoveries became a significant factor in undermining the old biblical myths about people whose skin color was different. 8. Discussion The achievements of explorers and astronomers of this period were extremely important for the role they played in bringing about a shift in the way people viewed themselves and the universe. Appleyard (1993:30) points out that the `discovery of the New World introduced the possibility of the radical ignorance into the human mind, the possibility that there was in infinity for us to know. ' Moreover, it exposed the weaknesses of all previous models of the universe. Medieval systems of the universe were extremely complex, but they drew boundaries. Appleyard (1993:32) suggests that the notion of a heliocentric universe removed the earth from its privileged place, because by the year 1700, the earth had become only a small part in an infinite universe. He also implies that Newton's universal laws made God's presence remote and no longer vital. The repercussions of these changes will be discussed in the next section. The spiritually corrosive nature of science is said to be an important by-product of the scientific revolution. Franklin lye van Bummer states: Science made the world of spirit ... seem unreliable and dim in comparison with the material world. In the 17th century, science drove revealed Christianity out of the physical universe into the region of history and private morals; to an ever growing number of people in the two succeeding centuries it made religion seem outmoded ... It changed profoundly man's attitude toward custom and tradition, enabling him to declare his independence of the past, to look down condescendingly upon the "ancients" , and to envisage a rosy future. Appleyard also (1992:9-12) discusses the effects ofscience on modern man's way of thinking. He suggests that science provides us with many solutions to problems, but these solutions are never conclusive. Scientists always try to find better solutions to problems. In his view, it is this tendency that seems to make scientific knowledge provisional; that is, it is constantly changing as theories come and go. 22 Thomas HARRAN'Hidenori ERA This characteristic of science has also affected man's spiritual condition. Because there are few absolutes in science, he is loathe to construct any private absolutes in public. Since he no longer has any outside order or system to refer to, he can only resort to making personal moral choices. These choices, however, cannot be made with total conviction because modern man must conform to the idea that anY moral choice he makes is merely one choice among countless others. The notion of absolutes has gradually eroded as people have felt compelled to tolerate all other notions of truth. 9. Summary of viewpoints Although Appleyard's argument that the influence of science brought about a spiritual malaise in the West seems plausible, the zoologist Richard Hawkins claims that science is not inherently anti-religious because everything that is discovered by science must be part of God's design. It is argued that scienge and theology have the same goals in that both seek to discover the truth (Carey, 1997:23). He points out that science seeks the truth about the physical universe, whereas theology seeks the truth about God. Although science and theology seem to have irreconcilable differences, Carey says that theology can be `regarded as a science which is committed to persistently questioning and reinterpreting the available evidence about God'. He maintains that the real conflict seems not to be between science and theology but between science and politics. Carey writes: .. the warlike and destructive uses to which science has been put have nothing to do with science: they are the responsibility of politics. He also says that there are essential differences between science and politics in that politics aims to coerce people and is concerned with the exercise of power, whereas science seeks knowledge. The somewhat ill-founded accusations that science has been the cause of modern man's spiritual malaise and amorality needs to be clarified. Appleyard's contention that science can tell us little about how we should do things or how we should live is not entirely convincing. Furthermore, he argues that the overwhelming impact of science has been the separation of knowledge from value. He contends that the spiritual vacuum created by science's destruetion of religious foundations has left modern man in a situation where he is unable to find his bearings because science can tell us nothing about the meaning, purpose, and significance of life. In order to narrow the focus of this discussion, it is necessary to examine some of the arguments against Appleyard's contention that science has brought about a kind AStudy of the Scientific Revolution 23 of spiritual crisis. Tb objectively respond to his assertions, one needs to define exactly what science is. Norman Hall provides us with a definition of what science is in his lecture given to the Atheist Coalition of San Diego. He writes: People who like to call themselves scientists attempt to contribute to the cooperative effort of building a scientific picture of the world. They make, collect, and compare observations; they attempt to judge which of those observations are more 1ikely to be true; and they endeavor to interpret them in terms of what is, in theirjudgment, the best currently available model or story, the one that they conclude is most likely to be true. In doing this, they adopt certain rules and methods, which may change over time, and which may differ in detail among different areas ofinvestigation. But these rules, be they called scientific method, procedural safeguards, or professional ethics, all have the same goal: that of avoiding the common pitfa11 of self-deception. If this is an accurate description of what scientists do, one can hardly be convinced that science is amoral and is unable to tell us anything about the meaning, purpose, and significance of our lives. Hall does, however, admit that deception can occur in science. He goes on to say: Deception can arise from premature but honest attempts to judge the value of theories based on only the limited observations available at the time; from errors ofhaste and wishfu1 thinking; from the pressures of ideology and politics; from the intoxicating prospects of the possibility of a new discovery; professional envy and ill-will; and, of course, the desire for personal success and its subsequent fame and wealth. Hall points out that perhaps `the most common motivation for self-deception is the wish for transcendence'. He argues rather ironically as follows: Scientific knowledge, tied as it is to physical reality, limited by human observation, shaped by the necessities of written and spoken language, and capable of giving us only probable answers, is a poor substitute for the Holy Grail ofAbsolute Truth. Wliy grub in the dirt of the world for information about reality if that reality is only a refiection of the perfect knowledge of a creator God? Wouldn't it be simpler, more elegant (and certainly more pious and spiritually sensitive) just to accept the knowledge that is revealed to us from on high? Afler all, what scientists do learn about the world is only what God has chosen to reveal to them. He goes on to argue that it would be impossible to justify doing science if the world were created and run by a transcendent intelligence. In addition, he suggests that controlled experiments could not be set up if one starts scientific research from the assumption that all knowledge about reality is simply a reflection of the perfect 24 Thomas HARRAN'Hidenori ERA knowledge of God. The claim that science is devoid of ethical principles, and that it can tell us little about how we should live does not seem to be a compelling one. The following quotations from Hall's essay point out the weakness of Appleyard's argument: In truth, it is impossible to derive "ought" from anything else than what limited knowledge we do have of what "is." And our knowledge of what "is" must be based in science. In spite of all of the claims to the contrary, there simply is no other source of knowledge. It is utterly amazing to me that people continue to believe and claim that science has nothing to say that could bear upon questions of normative ethics. Science is, I have claimed, nothing more or less than an open communal process that attempts to avoid self-deception, and to thereby discover that which is most likely to be true. If that is anything close to being an accurate description, then what are we supposed to use as a basis for morals and ethics ifwe reject or ignore science? The only remaining '`source of knowledge" would have te be some closed-minded, potentially self-deceptive system of thought characterized by an utter indifference to the probability that its pronouncements might or might not be consistent with observation and reason. And from that they want us to build a moral system? Hall elaborates further by explaining what the essence of science is: For better or worse, we really have no other choice but science as a basis for ethics -- andI think it is for the better. As Jacob Brunswick pointed out long ago that science doesn't just suggest an ethical system, it is and has been an ethical system all along. It is based on the premise that we wi11 take every precaution not to deceive ourselves, and the promise that we will not intentionally deceive others. That is the scientific ethic oftruth-telling. What a refreshing possibility as a foundation for all ethics ! In order to conclude the discussion of this paper, it is necessary to summarize briefly the arguments put forth by various schools ofthought: Appleyard argues that the growth of science inspired a new vision of the universe, of the world, and of man that was completely opposed to the old visions. He points out quite emphatically that the inroads of science have resulted' in the loss of modern man's sense of self. He is unable to find meaning and purpose for his life within the facts of the world because science has taken away his religion which, until the 17th century, had nurtured this sense and provided meaning for his life. According to Einstein, the conflict between religion and science is complicated by the fact that while most people agree on what is meant by science, many people differ on the meaning of religion. He distinguishes both science and religion as follows: AStudy of the Scientific Revolution 25 As to science, we may defme it for our purpose as methodical thinking directed toward fmding regulative connections between our sensual experiences. Science, in the immediate, produces knowledge and, indirectly, means action. It leads to methodical action if definite goals are set up in advance. For the function of setting up goals and passing statements ofvalue transcends its domain. As regards religion, on the other hand, it is generally agreed that it deals with goals and evaluations and, in general, with the emotional foundation of human thinking and acting ... Religion is concemed with man's attitude toward nature at large, with the establishing of ideals for the individual and communal life, and with mutual human relationships. Einstein argues that the conflict between science and religion came about because the mythical or symbolic content of religious traditions came into conflict with science. This occurs whenever the religious stock of ideas contains dogmatically fixed statements on subjects which belong in the domain of science. Galileo's attempt to convince the authorities of the Catholic Church that the Earth was not the eenter ofthe universe exemplifies this sort ofconflict. For this audacity, Galileo came close to death. Einstein points out that the desire for guidance, love, and support prompts men to form a social or moral conception of God. It is God who protects, disposes, rewards, and punishes. Hall maintains that a transcendental belief as a cure for fear and despair began when our forebears were mere hunters. It is his opinion that this cultural habit has long deceived us. It is our responsibility is to make sense of our existence, our culture, and our own ethics. Therefore, he thinks that we must build our own meaning of ethics and give up the belief that God is the source of ethics. 10. Concluding remarks Fears and criticisms of science have emerged, however, because so many people have become disillusioned with it. There are concerns about the harmfu1 effects of technology in society, and the environmental destruction affecting our planet. In order to calm peoples' fears and worries, scientists need to listen more attentively to their concerns. Scientists should not forget the Baconian ideal of utility-that science should be used for the benefit of mankind; that is, to improve society and to enrich the lives of all people on Earth. Furthermore, many people have become indifferent to science because they think it is unable to answer moral and religious questions. According to Hall the tension between science and religion resulted from excessive zeal and misunderstanding on both sides. He writes: 26 lhomas HARRAN•Hidenori ERA Peacefu1 coexistence and even a measure of syncretism are now assumed to be possible as long as each concedes to the other's authority in their separate worlds of knowledge: that of matter and facts for science, and that of the spirit and values for religion. A quotation from Richard S. Westfa11's essay entitled "The Scientific Revolution" epitomizes the impact of modern science. In his essay, he concludes: For good and for ill, science stands at the center of every dimension of modern }ife. It has shaped most of the categories in terms of which we think, and in the process has frequently subverted humanistic concepts that furnished the sinews of our civilization. Through its influence on technology, it has helped to lift the burden of poverty from much of the Western world, but in doing so has accelerated our exploitation of the world's fmite resources until already, not so long after the birth of modern science, we fear with good cause their exhaustion. Through its transformation of medicine, science has removed the constant presence ofillness and pain, but it has also produced toxic materials that poison the environment and weapons that threaten us with extinction. Any attempt to provide a solution to this dilemma might be viewed as somewhat hubristic. Therefore, I will refer to one of the most famous novels of modern times, Lord of the Flies, to make some concluding remarks concerning the developments discussed in this paper. The pervasive infiuence of secularism has made it increasingly difficult for modern man to experience life in a religious way. The most significant events of our lives - conception, birth, sickness, death- seemed to have lost their mystery Modern man finds himselfisolated on an `island', surrounded by the forces of science and technology, and fanatically hunting for ways to find solutions to his own social breakdown. One can draw a parallel between our own plight and that of the boys in Golding's novel. They are fooled into believing that there is a beast on the island and desperately spend their days hunting it down. Only one of them realizes that the beast really does not exist on the island but is in their own hearts. Likewise, modern man is also fooled by a `beast'. He blames science and technology for the evils ofthe world, but the roots ofthese evils are most likely due to the use to which he puts science and technology. Golding's book also calls to mind the so-called "ostrich syndrome." Just as ostriches tend to bury their heads in the sand when predators approach them, many people prefer to ignore evils even though they could be avoided by simply changing their patterns of behavior.
