“History is often about reminding us of things we’ve forgotten,” said Prof. Lawrence M. Principe of Johns Hopkins University in a course titled “Science and Religion,” one of The Great Courses of The Teaching Company (www.teach12.com), published in 2006. Professor Principe is both an organic chemist and a historian of science. He wants to remind us that science and theology have not, historically, been at war with each other. They have come into conflict over particular scientific or theological positions, but so does conflict arise between scientific positions and between theological positions. Conflict is typical of intellectual discourse, be it about the natural world or about the world beyond the material we can sense (directly or indirectly). The two types of truth-seeking have grown up together within Western Christianity with much in common, informing each other along the way.
Theology Informing Science
Theology pioneered the logical analysis and disputational techniques we think of now as distinctive to rational inquiry, science in particular. More surprising may be that medieval theologians developed the modern preference for explaining natural events in terms of natural causes. They realized that only natural causation is really comprehensible to the human mind. While a natural cause, like the wind, may itself have a supernatural cause, like God, only the natural or secondary cause we can comprehend has any explanatory power. Recourse to the supernatural is pointless, because it is beyond our comprehension. This is “methodological naturalism,” a practical theological invention that has become the foundation of modern science. This is not the same as “philosophical naturalism,” which claims the “natural” is all there is, that there is no “supernatural” world. This is a philosophical, not a scientific, assertion. The very nature of science puts the supernatural beyond the scope of scientific understanding.
Science Informing Theology
On the other hand, according to Prof. Principe, St. Augustine asserted “the need for up-to-date demonstrated natural knowledge among theologians and exegetes [interpreters of Holy Scripture].” St. Augustine himself (A.D. 354-430) spent 15 years in rational interpretation of Genesis I in light of Greek philosophy and mathematics and then-current knowledge of the natural world. He concluded that the universe started in an instantaneous moment of creation and developed over time into what contemporary astronomers could see. The Big Bang Theory was thus anticipated before medieval times by one of the most foundational leaders and thinkers of Christianity! Prof. Principe also claims the idea that living beings could arise naturally from non-living matter would have surprised no medieval theologian. “Christian theology has proven itself remarkably flexible in its ability to adopt, adapt, and explore new scientific findings— to see in essence what they mean.” “Theology has come away from the encounter with new views of man’s place in relation to the creator of time, space, and nature.”
A 20th-Century Conflict – Social and Political, Not Intellectual
What to make then of the conventional wisdom that science and religion are perpetually at odds? In 12 excellent lectures, Prof. Principe lays out the historical argument that this conflict is more apparent than real and relatively recent historically and surprisingly trivial intellectually. It seems Charles Darwin was reacting to an unnecessarily narrow and distinctively English Protestant interpretation of God and Christianity. Moreover, the modern-day conflict between evolution and creationism (or intelligent design) is just that, modern, a phenomenon of the 20th century, not the 19th. And it is more a social and political conflict among naïve interpreters of science and Christianity than it is an intellectual conflict.
Charles Darwin in Proper Historical Context
Before further exploration of the life and work of Charles Darwin after his return from the voyage of the Beagle, I will explore in the next few posts the general history of the relationship between science and religion, using Prof. Principe’s lectures as my primary guide (triangulation from different sources to come later). As I have argued at the outset of this project, it is critically important to put Charles’s thinking in the proper historical context, so that we understand to what he truly was reacting as he developed his theory of evolution and his ideas about God and religion.
Defining Science and Religion
Prof. Principe carefully defines his terms. “The content of both science and religion is made up of statements and claims about the way things are; science, about the way things are predominantly, but not entirely, in the natural world; theology predominantly, but not entirely, about the way things are in the spiritual world.” They each include both a body of knowledge claims and a set of methods for gaining, assessing, accumulating and integrating the knowledge claims. Methodologically, good science and good theology are quite similar, even though their knowledge claims are mostly about quite different realms of reality.
Prof. Principe distinguishes religious practice, theology and faith. Practice refers to “the observances and actions that flow from a religious commitment, for example, attending church, giving alms, praying, fasting at particular periods, moral self-discipline, and so forth.” Theology “is the intellectual, methodical study of God, the spiritual world, God’s attributes, actions, and relationship to creation [the natural world].” Faith “is a method of arriving at knowledge claims. The method is by simple belief, by assumption, or suspended disbelief.” When talking about the interaction of science and religion, we are very often talking about science and theology and typically in the historical context of Western Christianity, which created the culture within which modern science arose.
Traditional Christian theology generates its knowledge claims not just from faith but also logical argument, deduction, and reason. Prof. Principe points out that the works of medieval theologians are masterpieces of logical analysis and rational argument. For example, we scientists often fall back on a logical principle called Ockham’s Razor, named after a 14th-century Franciscan theologian. Likewise, science depends on a number of faith statements (implicit assumptions) in order to operate, such as the natural, physical world having an independent existence outside our minds, and that our senses are giving us (directly or through an instrument, like a telescope or a microscope) reliable information about the natural, physical world, and that this real world behaves in ways that are regular and law-like (the rules don’t change every few minutes). Prof. Principe assures us that these and similar assumptions, or leaps of faith, cannot be proven true. Nonetheless, they prove themselves useful, indeed essential, for science to progress. We are comfortable with these leaps of faith, because they allow us to generate reliable and useful knowledge claims about the world around us.
No Easy Distinction of Science and Religion
Thus, we cannot distinguish science and religion simply by saying that one is informed by reason alone and the other by faith alone. Nor can we segregate them by saying the realm of science is the natural or material world that we can observe and the realm of religion is the spiritual world which we cannot know with our bodily senses. Prof. Principe is careful to say their realms of study are “predominantly, but not entirely” distinct, because there is overlap, and some of the most productive interaction between science and theology has taken place in these overlapping areas.
St. Augustine and the Two Books
Christian theologians have made testable claims about the natural world, as St. Augustine did regarding the origin and evolution of the universe. His sources were what he called the Two Books, the Book of Nature and the Book of Scripture, the two ways St. Augustine believed by which God reveals himself to humankind (inspiration of scripture authors and creation of the natural world). St. Augustine’s methods were both faith (Christian belief) and reason (Greek philosophical knowledge drawn from astronomy and other observations of the natural world). St. Augustine insisted on the unity of truth; if reason tells us one thing and faith tells us another, then this disagreement must be resolved. There is no teacher of truth but God, he wrote, and since God is omniscient and always consistent, there must be a single truth. This is a fundamental faith-based assumption that underpins both theology and science; it is a claim that pertains to both the spiritual and natural worlds—here is a major overlap of faith and theology into study of the natural world. Scientists don’t have to believe in God to make this leap of faith, to assume the unity of truth, but the assumption is fundamentally theological (drawn from knowledge claims about the characteristics of God).
Unity of Truth
The unity of truth requires St. Augustine to assert that the Book of Nature and the Book of Scripture cannot contradict each other. However, both Books require careful interpretation. If they appear to contradict, then St. Augustine would insist this is solely because of incorrect interpretations. Understanding Nature does not reliably come from just using our senses; we have to apply rational analysis. Understanding Scripture is even more difficult, since the passages have literal, allegorical and moral meanings simultaneously.
“Literal” Interpretation of Genesis I
Much to my surprise, St. Augustine claimed that the literal meaning is the hardest to get right. The surprise comes from our modern notion of biblical literalism as “believing every word of the Bible”—the surface meaning of the words. Prof. Principe points out that for St. Augustine and all theologians until recently, “literal” means “interpretation of a passage in such a way that it maintains its connection to the topic it seems to be describing and assigns meanings to the individual words so that the passage makes sense in relation to other sources of knowledge.” St. Augustine spent 15 years working out his literal interpretation of Genesis I. He was not satisfied with his work until it resolved contradictions within the text itself and “provided an account of creation harmonious with both reason and knowledge from other sources” (the Book of Nature, in particular). Prof. Principe quotes St. Augustine: “Interpretation of biblical passages must be informed by the current state of demonstrable knowledge.” St. Augustine warned against the danger of embarrassing the reputation of Christianity by being ignorant or dismissive of the demonstrated scientific knowledge of the day. From the viewpoint of traditional Christian theology, science is essential for full understanding of the “literal” meaning of divinely-inspired scripture (and vice versa).
History of Partnership
Science and religion continued in intimate partnership through the medieval apogee of the Roman Catholic Church in Western Europe and even through the rise of Protestantism and the birth of modern science and the Enlightenment. Very often the early “natural philosophers” (not commonly called scientists until the 19th century) were in holy orders, because a position in the Church allowed time and even incentive to pursue knowledge of the natural world and how it works. Francis Bacon, Robert Boyle and Isaac Newton saw their scientific work as discovery of the divine rules governing the universe and even the nature of God. Prof. Principe devoted two lectures to explaining that even the famous conflict between Galileo and Pope Urban VIII was not truly about the resistance of the Roman Church to the heliocentric conclusions of Copernicus and Kepler. The Galileo affair was driven by personal arrogance and misunderstandings, bureaucratic rivalries, political problems of the Roman Church, and Galileo’s insistence on his theory of what causes the ocean tides, which later was proven wrong, showing the wisdom of Church safeguards against being too quick to rewrite doctrine in response to new scientific “discoveries.”
Even in modern times, churchmen have been responsible for major scientific advances. Gregor Mendel’s experiments in breeding garden peas laid the foundation of modern genetics and ultimately the modern understanding of biology and Darwinian evolution by natural selection. Mendel was also the abbot of an Augustinian monastery in what is now the Czech Republic. The modern Big Bang theory of an expanding universe began with a 1927 paper by Georges Lemaître, a Belgian Catholic priest who also had a PhD from MIT and was a professor at the University of Louvain. In 1960, Lemaître became president of the Pontifical Academy of Sciences. Speaking of the Catholic Pontiff, Pope Pius XII endorsed the Big Bang theory n 1951, after Einstein’s endorsement and well before the theory’s full acceptance in 1966 over the competing Steady State theory, promoted by the vociferously atheistic, anti-religious physicist, Fred Hoyle.
Other Forces Driving the Science-Religion Conflict
Good science does not necessarily beget atheism, nor does formal religion necessarily negate good science. Scientists and theologians do not now, and history shows they never did, divide into opposite camps. There was indeed conflict between them but also within the two professions. The range of responses among theologians to scientific discoveries and theoretical propositions spanned the full range from blind prejudice to full embrace. In summary, there are other forces at work in driving the Science and Religion Debate besides science and religion. The next blog will explore these other forces and how they have driven the debate into a kind of culture war.

The Voyage of the Beagle – Antecedents
Published August 17, 2008 The Voyage of the Beagle Leave a CommentTags: Biography, Books, commentary, Friends, History, psychology, Reviews, Society
In 1831, Charles Darwin was earning a lack-luster degree from Cambridge University and setting his sights on becoming a clergyman of the Church of England. He was not enthused by the prospect, but he stood a good chance of getting a rural parish. This would allow him to indulge his passion for natural history on the side, as had many rural clergymen for whom a career with the Church was more means than end. Not that Charles was in the least insincere. His father, Dr. Robert Darwin, having concluded that medicine was not for Charles, allowed him to leave Edinburgh University without a degree (as had his older brother, Erasmus) and enroll at Cambridge University to study the classics in preparation for a profession in the Church. This had long been a fall back position for gentlemen in need of a respectable profession. Before accepting his father’s offer, Charles considered carefully his ability to pledge himself to uphold the finer points of Church doctrine. After much reading and thinking on the question, Charles decided that he could do it: “… as I did not then in the least doubt the strict and literal truth of every word in the Bible, I soon persuaded myself that our Creed must be fully accepted.” (from his Recollections). And so he went up to Cambridge.
Charles at Cambridge
His brother had preceded Charles to Cambridge and had told him about Professor John Stevens Henslow as a man who knew every branch of science. His cousin and close friend, William Darwin Fox, a fellow beetle enthusiast, also went to Cambridge and soon got Charles an invitation to the regular Friday evening gatherings of students and faculty at Professor Henslow’s home to explore common interests in the natural world. Something about Charles made him stand out enough for Henslow to take him under his academic and personal wing. More than mentor and student, Henslow and Charles became field trip companions and soon very good friends. In early 1831, after Charles had effectively completed his course work but still had to reside on campus for another two terms to fulfill degree requirements, Henslow encouraged Charles to take up geology under the tutelage of the revered Professor Adam Sedgwick. Again the relationship became close. Sedgwick invited Charles to accompany him during the summer on a geological transect of North Wales. He taught Charles the intimate details of how geologizing was then done. Charles loved the vigorous hiking across the landscape, observing and collecting samples with his new geological hammer, and putting the pieces of evidence together in a coherent map and understanding of the geology of the area. Still, he was anxious to get back home in time for the start of the fall partridge hunting. The start of his career with the Church could wait another few months.
FitzRoy Plans the Beagle’s Return to South America
Also in 1831, Robert FitzRoy was planning a second voyage in command of HMS Beagle to map the coasts of the “southern cone” of South America. FitzRoy was in his early twenties but already an accomplished naval officer when he joined the earlier expedition at its midpoint. The Beagle had sailed with HMS Adventure under the overall command of Phillip Parker King. The expedition returned to England in 1830 with much work left to be done. A second expedition was needed, but King decided to retire and live in Australia, so command of the second voyage fell to young FitzRoy with only the Beagle sailing this time.
Their coastal mapping mission was motivated by the opening in the 1820s of the newly independent South American colonies for commercial relations with countries other than Spain and Portugal. To facilitate trade by commercial shipping, and its ability to protect this trade, the Royal Navy needed more consistently accurate and detailed charts of the South American coasts and adjacent waters. The expedition also was of vital strategic importance to learn more about these countries in general, especially their people and natural resources as producers of commodities to feed the growing demand of Britain’s industrial revolution. Scientific exploration served national interests, and military careers in the poorly known regions of the early nineteenth century world not only permitted but even encouraged interest in natural history, from which knowledge of natural resources was likely to come.
In Need of “Some Well-Educated and Scientific Person”
FitzRoy was given command of the Beagle quite suddenly on location in South American waters when her captain, Pringle Stokes, committed suicide. The incident and his own experience of command heightened FitzRoy’s concern about the pressures and loneliness of command at sea, especially given his particular vulnerability to bouts of despair. This time he wanted a gentleman companion to share his cabin and meals, to dispel the loneliness and distract him from the relentless pace of work he was inclined to set for himself. He asked a friend, who declined. FitzRoy therefore asked Captain Francis Beaufort, Hydrographer to the British Admiralty (and inventor of the Beaufort Scale for describing wind force) to help him find a suitable gentleman. It was appropriate that he ask Beaufort, as he was the technical supervisor of the expedition and was engaged in writing FitzRoy’s “terms of reference” (as we today would call his memorandum describing in detail the mapping and other assignments for the second voyage). In FitzRoy’s own words, he “proposed to the Hydrographer that some well-educated and scientific person should be sought for who would willingly share such accommodations as I had to offer, in order to profit by the opportunity of visiting distant countries yet little known.”
When FitzRoy requested a “gentleman,” he was not asking for just any well-mannered sort of fellow but a person of particular social status and outlook compatible with his own – a man of his own class with whom he could deign to associate as an equal. Actually, FitzRoy was an aristocrat descended from Charles II, but he would find a “gentleman” of some wealth, education, and refinement quite acceptable. Beaufort contacted Professor Peacock of Cambridge University, and the old school network was activated. Peacock contacted his friend, Professor Henslow, who was sorely tempted to take the position himself, except for the forlorn expressions of his wife and young children. Henslow extended the invitation to Charles Darwin, as a very capable, if “unfinished” naturalist. After some famous hesitation, Charles accepted to go to London immediately to meet FitzRoy, to see if both could stand the idea of spending years together in the intimate quarters of a ship at sea. After some equally famous hesitation by FitzRoy regarding the shape of Charles’s nose (phrenology, or study of the shape of face and head, was seriously considered by many educated people of that time), the two decided they liked each other and sealed the bargain, with the understanding that Charles (rather, his father) would pay all his own costs and would be designated the Captain’s personal guest, with liberty to leave the voyage at any port of call, to return by another ship to England. FitzRoy was concerned from the start about the staying power of any companion he invited along.
Bonds of Friendship, Adventure and Ambition
During preparation of the Beagle in the autumn of 1831, these two young men, Robert FitzRoy, 26, and Charles Darwin, 22, quickly became friends, united by the excitement of high adventure to come. Just imagine the anticipation of Charles as FitzRoy and his crew figuratively and literally showed him the ropes, helping him buy the right equipment and stow his gear in the tight spaces of the tiny cabin, even demonstrating how to hang his sleeping hammock and get into it without being thrown to the deck! Charles was not the only landlubber guest of FitzRoy who must have amused the Beagle crew. In addition to the complement of 65 crew, FitzRoy brought along nine “supernumaries,” counting Charles. The others included a “draughtsman,” Augustus Earle, to record the voyage in paintings as well as, I presume, to make good-looking maps from the charts created by FitzRoy and his officers. And an “instrument maker,” George Stebbing, to tend the 22 finest chronometers ever carried around the world, for FitzRoy to measure “meridian distances” that would greatly improve accuracy of locating major geographic features of the earth by longitude, still a relatively new method (this task was the primary motive for circumnavigating the globe once the work of surveying the South American coasts was completed). And Richard Matthews, a missionary, and three Fuegians FitzRoy had brought back to England from the first expedition and educated at his own expense; Matthews and the Fuegians were to establish a mission at the bottom of the world, the vanguard of Christianity in Tierra del Fuego. Plus FitzRoy had his own steward, and Charles had his own servant, especially to assist in his collecting and preserving of specimens.
Excepting Charles and his servant, all these supernumaries and more were at FitzRoy’s personal expense. To our modern ears, it seems quite remarkable that a military expedition would include the personal projects of its leader and mix public and personal funding of the diverse endeavors. But this was typical for the time. Such expeditions were usually led by wealthy, upper-class men who often had ambitious agendas of their own, compatibly mixed with service to the Crown.
Adding to the bond forged between adventure travelers, FitzRoy and Charles shared a common ambition to use the opportunity of the voyage to establish themselves as experts in their respective professional fields and thereby launch their careers and secure their positions in English society. An expedition to unknown lands, discovery of new knowledge, and the subsequent reports of the findings had established the reputations and positions of many young Englishmen prior to the second expedition of the Beagle. Therefore, both FitzRoy and Charles could clearly see the future rewards of literally staying the course, of persisting through the long years of privation, hardship, danger, homesickness, hard work, and boring weeks at sea. The burden was relieved, no doubt, by their sharing the resolve to see it through. FitzRoy had the added incentive of being under Admiralty orders. For Charles, completing the voyage was optional; on the other hand, he was motivated by intense desire to prove himself in some important way – especially to his family, it seems. Plus, he was passionately committed to the work, and he knew how FitzRoy and Henslow and Sedgwick and many others in scientific English society thought it so exciting and important. He had a respectable profession, at last.
. . .
I have based the foregoing on three books. Charles’s Recollections, introduced in my previous posting, devotes only eight pages to the period of the voyage, mainly adding some personal information about his relationship with FitzRoy and events leading up to the sailing of the Beagle on December 27, 1831. Charles’s public account of the voyage, drawn from his daily journal, was first published with FitzRoy’s account in 1839, and later in the same year as a stand-alone book entitled Journal of Researches into the Geology and Natural History of the Various Countries Visited by H.M.S. Beagle, under the Command of Captain FitzRoy, R.N. from 1832 to 1836. This book of travels was a surprising publication success; several editions were published with variations of the title and translations into several languages. It continues to be widely read today. Charles admitted in his Recollections that “The success of this my first literary child always tickles my vanity more than that of any of my other books.”
The version I have read carefully is the Penguin Classics book, Voyage of the Beagle, published in 1989 – this is the first (1839) edition of Journal of Researches edited and abridged by Janet Browne and Michael Neve. “Abridged” means that Browne and Neve reduced the length of the original first edition by removing whole sections they deemed of less interest, without touching the remaining sections, shortening the whole by about one third. I admit to being grateful for the abridgment. Charles wrote well, often with vivid imagery and lively spirit, but his was still an early 19th century literary style. I love Jane Austen, but Charles was not that good, and often it is a slog to follow his prose. Moreover, I find his rather long geological digressions on the landscapes he traveled through quite tedious, and I am just not interested in his minute invertebrates (there is one memorable passage (p. 191) about zoophytes in the seas around the Falkland Islands which left me totaled puzzled after several readings). The scientific expedition narratives of the time served the dual purpose of entertaining the generalist readers as well as informing the experts looking for information new to their specialty, creating in an uneven reading experience.
I preferred reading the first edition, rather than the 1845 second edition, for which Charles “took much pains in correcting” the first edition, possibly obscuring what he was thinking or not thinking during or shortly after the voyage. For example, I understand (and plan to verify) that he made more of the Galapagos observations in the second edition than in the first, overlaying his later interpretations on the raw observations and initial reactions during his visit to the archipelago in Sept-Oct 1835.
Browne and Neve do the reader a very great favor in their 26 pages of introduction. Seldom have I found an introduction more enlightening and useful. I am indebted to them for most of what I have written above about the historical context of the Beagle expedition and the background on Robert FitzRoy. I highly recommend this introduction as an important document in itself.
Browne and Neve very usefully attach two appendices: “Admiralty Instructions for the Beagle Voyage” which includes Beaufort’s memorandum of detailed assignments for FitzRoy, and “Remarks with Reference to the Deluge” written by Robert FitzRoy himself as a counter to Darwin’s geological interpretations of what the two men saw together in distant lands. Both of these pieces first were published in the second volume of FitzRoy’s Narrative of the Surveying Voyages of HMS Adventure and Beagle (1839). Charles’s Journal of Researches first appeared as the third volume of FitzRoy’s Narrative. I drew insights from the “Admiralty Instructions” in writing this post and the next. FitzRoy was given a daunting set of surveying and other tasks, and his faithfulness to the instructions accounts for the length of the voyage extending from the original (and unrealistic) projection of two years to almost five years.
The third book is the Darwin and the Beagle by Alan Moorehead, published by Harper & Row in 1969. This is the first book I read about Darwin himself (rather than his theory and its impacts). I was a young graduate ecology student at the time. Moorehead’s book tells the story of Charles and the Beagle experience so well, and so beautifully illustrated with contemporary paintings and sketches of the places, people and creatures, that it awakened in me a longing to travel the world, seeing it as an ecologist, especially the tropics. I was the same age as Charles when he boarded the Beagle, and I identified with his youthful desire to see what he had only read about in books and his ambition to contribute something new to science. I hoped that I, too, would gain wonderful insights from experiencing new natural worlds. I highly recommend Moorehead’s book even today as an easy and compelling way to travel vicariously with Charles on his famous voyage.
However, in re-reading this book recently, I was reminded of the ever-so-subtle way an author, whether Moorehead or any other (including me), can create impressions that distort historical facts, without conscious intention to deceive or obscure. Moorehead highlights a bit too much the intellectual conflict between Darwin and FitzRoy, during the voyage itself, regarding interpretation of geological observations. He creates an impression of confrontation between the enlightened scientist just looking at the facts and the fundamentalist Christian clinging doggedly to the literal truth of the Biblical account. As in most books about Darwin and evolution, Moorehead approaches his task with unspoken celebration of the triumph of the modern mind, as science defeats religion, as reason overcomes ignorant tradition, as light dispels the darkness. Browne and Neve, in their introduction, paint a more complex and interesting portrait of the relationship between Charles and FitzRoy during the voyage. No doubt they engaged in running debate as they tried together to make sense of what they encountered along the way (reflected by FitzRoy’s “Remarks”), but it seems to have been a friendly exchange between mutually respectful and relatively open minds that only later fully settled on diametrically opposing interpretations of fact. During the voyage, they had some famous arguments, such as about the benefits of slavery in Brazil, reflecting their different political upbringings. But it is doubtful that either grew furious with the other over their interpretations of the history of South American landscapes, much less the origin of species.
In this posting, I have dwelled mostly on antecedents to the voyage of the Beagle. In my next posting, I will summarize what I have learned about the events of the voyage itself.
