Between Nature and Society: Empowering Research on the History of Science

Title page. On the Origin of Species by Charles Darwin. Contributed in BHL from Harvard University Botany Libraries.

Charles Darwin is a household name. One of the most famous naturalists to ever live, he is known around the world for his publication On the Origin of Species and contributions to evolutionary theory.

The work of contemporary scientists informed the development of Darwin’s evolutionary concepts. By applying, and sometimes countering, the theories of others, he constructed one of our most important scientific foundations. He documented this intellectual progression in the margins of the books in his library. This historically significant collection is available online in the Biodiversity Heritage Library.

Charles Darwin’s Library is a digital edition and virtual reconstruction of the surviving books owned by Charles Darwin. Produced as a collaboration between BHL, Cambridge University Library, the Library & Archives of the Natural History Museum in London, and the Darwin Manuscripts Project, the collection draws on original copies and surrogates from other libraries and includes over 500 of the 1,480 books in Darwin’s library. Notably, these books are complemented with fully-indexed transcriptions of Darwin’s annotations.

Charles Darwin’s Library is particularly meaningful to Dr. B. Ricardo Brown, Professor of Social Science and Cultural Studies at the Pratt Institute. Brown has devoted years of research to Darwin and the impact of his evolutionary theories on debates around monogenetic vs. polygenetic human origins. Brown’s 2010 book, Until Darwin: Science, Human Variety and the Origin of Race, explores the complex web of factors that influenced these debates from the 17th-19th centuries and the impact of the publication of On the Origin of Species on this scientific discourse.

Brown spent nearly 10 years researching this book. Today, BHL’s open access collections offer researchers considerable time-savings.

“I am sure that if I had the kind of access to texts that BHL now provides researchers, I could have reduced the research time for Until Darwin in half,” muses Brown.

With academic backgrounds in environmental studies, sociology, and critical theory, Brown’s research explores the history of science, investigating the relationship between society and nature and the “genealogies of systems of knowledge” through which we make sense of these relationships. His current project looks at sociology and ecology as “sciences of life” whose formation was made possible by the dissolution — marked by Darwin’s Origin — of political economy and natural history.

“Without BHL, such a project would be much more limited, if not impossible,” affirms Brown. “The Library’s impact has been immense.”

Brown refers to BHL at least several times a week. A great benefit of the Library is that it has facilitated unexpected discoveries that expand the scope of relevant literature for his research projects.

“BHL makes it possible to browse through the library and (virtually) pick-up an unfamiliar work or author and discover something that is relevant or just interesting — which you might not have come across without BHL,” explains Brown. “There is much to be said for the pleasures of simply exploring the archive.”

Beyond serving as a vast archive of texts, artifacts, and scientific ideologies, BHL also facilitates Brown’s interest in ecology and environmental studies by allowing him to compare his own field observations to those of past naturalists.

“I found that it is quite useful to do some field observations and hikes when immersed in the study of Darwin and the Natural History of his time,” says Brown. “One gets a better insight into Darwin’s methodology, which depended on his own observations and those of trusted naturalists and correspondents.”

Take, for example, Darwin’s observations on slave-making ants.

“Darwin constantly tacks back and forth between his own observations and those of the recognized authority on the slave-making ‘instinct’ in ants, Pierre Huber,” explains Brown. “This series of observations led Darwin to conclude that the ‘instinct for slavery’, in ants as well as human societies, was in no way ‘miraculous’ or evidence of a fixed or natural hierarchy.”

Brown also finds BHL to be a useful educational resource for his courses.

“BHL provides a means for students in my courses to access and download PDFs of texts that only a few years ago would have been known to them only through secondhand descriptions, summaries….or long lectures,” affirms Brown. “ As Pratt is primarily a school of art, design, and architecture, students appreciate the aesthetic skills of early naturalists that they experience through BHL’s high resolution images. Works such as Cuvier’s Tableau élémentaire de l’histoire naturelle des animaux or Haeckel’s Kunstformen der Natur provide a wonderful avenue for understanding the social relations of art, aesthetics, and science.“

With much of his research focused on the investigation of science and society’s influence on each other, he’d love to see BHL incorporate functionality allowing readers to explore the social and cultural contexts of the texts in the Library.

“By its inclusion in the collection, each text potentially takes on a certain legitimacy,” considers Brown. “This means that texts such as Morton’s Crania Americana or Pouchet’s The Plurality of the Human Race might, despite or perhaps even because of their age, be misread as somehow giving voice to views that remain contested. And because much of the history of science is the history of errors, this issue takes on a particular importance when authoritarian movements are constantly seeking to co-opt a wide variety of knowledges — for example, Classical and Medieval Studies, Darwinism, Ecology and Environmental Studies — to the service of supremacy.”

As we explore opportunities to link our content with other resources, collections, and databases in future iterations of BHL, including through linked data applications, strategies to provide this context will hopefully become increasingly feasible.

While many aspects of BHL’s collections and services have been important to Brown’s research, his favorite feature of the Library is that it is free and open to the public.

“BHL makes the history of science available to everyone,” praises Brown. “It would seem to have significant potential to enrich citizen science projects, as well as public discourse on climate change, extinction, the authority of science, the domination of Nature, and much more.”

We’re proud to know that, by making our collections globally accessible to anyone with an Internet connection, BHL is helping to advance a wide range of research and inspire discovery of the natural world.

Happy Darwin Day!

Charles Darwin by George Richmond. Cambridge University Library.

Today in 1809, Charles Darwin, remembered for his theory of Evolution by means of Natural Selection (which was so eloquently outlined in the 1859 publication On the Origin of Species by Means of Natural Selection) was born. We celebrate this day as Darwin Day.

In 2011, BHL released Charles Darwin’s Library, a collection of books found in Charles Darwin’s personal library, with his hand-written annotations marked-up and indexed. We made a selection of these books available for free download in iTunes U. This year, we’ve selected images from these books and created a Darwin collection in Flickr. As with all BHL content, these images are free for download and reuse.

As we continue our celebrations of this great man of science, we highlight another project (headquartered at the American Museum of Natural History) which is dedicated to providing free access to Charles Darwin’s scientific manuscripts – the Darwin Manuscripts Project.

In this two-part post, Darwin Manuscripts Project Director, David Kohn, examines four of Darwin’s manuscripts that show the development of his evolution theory. Let’s begin with excerpts from “Ornithology Notes” and Darwin’s “Transmutation Notebook.”

Celebrating Darwin Day. By David Kohn. Director, Darwin Manuscripts Project

The Darwin Manuscripts Project has the admittedly ambitious goal of publishing all of Darwin’s scientific manuscripts. When digitized this will come to well over 100,000 high-resolution images, which we aim to faithfully transcribe and edit to the exacting standards of contemporary textual and historical scholarship. Among all these manuscripts my first love has always been those items that reveal—or at least allow us to glimpse at—the development of Darwin’s commitment to transmutation (his term for evolution) and the insights that led him to natural selection and eventually to the Origin of Species. Beyond their intellectual content, what appeals to me is how passionate are these manuscript glimpses of Darwin deeply in the midst of theory creation. So I’ve selected three items that capture chronological high points in what must be the most crucial intellectual journey in the history of natural history. And then I’ve selected two manuscript pages from the end point of the journey—the Origin itself. The entirety of this  journey can easily be followed on the DMP site by going to Edited Manuscripts (in the left-hand navigation) and then selecting ‘Creation of the Origin’, where the reader will find all the many surviving documents that are relevant to this process from 1835 to 1859.

Ornithology Notes, Summer 1836

(Cambridge University Library, DAR 29.2: 73-74)

Ornithology Notes. Pg. 74. Cambridge University Library.

I want to focus on the following passage about the slightly different forms of mocking birds Darwin found as he travelled from island to island. This was written in the summer of 1836 and is a significantly revised version of notes written in 1835, shortly after the Beagle left the Galapagos.

“When I see these Islands…tenanted by these [mocking] birds…I must suspect they are only varieties. … If there is the slightest foundation for these remarks the Zoology of Archipelagoes, will be well worth examining; for such facts «would» undermine the stability of Species.”

What a tantalizing passage. What does he mean by the concluding remark: ‘undermine the stability of Species’?

Undoubtedly, this remains one of the most controversial passages in the Darwin manuscript corpus. And I am offering a part of my humble, yet accurate, interpretation. By ‘stability’ Darwin means immutability. For stability of species is the exact term that Charles Lyell used when he discussed Lamarck’s evolutionary theory at length in the Principles of Geology. By 1836, Darwin had almost four years to read Lyell. And we know definitively he had read and indeed thought about Lyell’s anti-evolutionary views by February 1835. While there are several ways that Darwin was exposed to evolution before the voyage, Lyell’s deep exposition of Lamarck was, I believe, the most important exposure. For reading Lyell gave Darwin a major and thorough injection of evolution theory at the very time when Darwin was actively collecting specimens. But this belief has to be a matter of guess work because Darwin did not begin annotating his books until after the Beagle voyage. (If you really want to have some fun browse through the heavy marginalia on Darwin’s immediately post-Beagle copy of the 1837 edition of Lyell’s Principles in the Charles Darwin’s Library collection at BHL: http://biodiversitylibrary.org/item/105893 and http://biodiversitylibrary.org/item/105574.)

So to me ‘undermine the Stability of species’ translates as to ‘negate immutability’. Logically, to negate immutability equates to assert evolution. But in this passage Darwin did not assert evolution—not yet. We learn that the logic of discovery can proceed more gradually than mere logic.  However, this passage is an extremely important index of Darwin’s intellectual development. For while it shows that Darwin was not yet an evolutionist, it also shows that he was thinking about evolution and indeed thinking that evidence he had collected could destroy the received view that species are perpetually immutable.

Some more context is necessary.  When he wrote this passage, Darwin was in the midst of an important transition. South America and the years of specimen collecting were long behind him. So as a scientific expedition, the voyage itself was behind him. Yet with the ship homeward bound in the Atlantic, the voyage had not yet ended. But Darwin is already looking to the near future, when he would make a powerful entrance into London’s scientific scene by delivering his Beagle specimens to specialists to identify, describe, and evaluate. For these are the people who will determine whether or not his evidence on the ‘Zoology of Archipelagoes, will be well worth examining’. But now, while still sailing, Darwin was prepared to speculate, and indeed to set the grounds for his future evolutionary theorizing.

 

Transmutation Notebook D 134e-D135e, 28 September 1838

(Cambridge University Library, DAR 208: 73-74, http://darwin.amnh.org/viewer.php?eid=75168 and http://darwin.amnh.org/viewer.php?eid=75169.  For the whole Notebook D see http://darwin.amnh.org/viewer.php?mid=7.)

28th. «I do not doubt, every one till he thinks deeply has assumed that increase of animals exactly proportiona[l] to the number that can live.—» We ought to be far from wondering of changes in number of species, from small changes in nature of locality. Even the energetic language of ‹Malthus› «Decandoelle» does not convey the warring of the species as inference from Malthus.— … population in increase at geometrical ratio in FAR SHORTER time than 25 years— yet until the one sentence of Malthus no one clearly perceived the great check amongst men.— … One may say there is a force like a hundred thousand wedges trying force ‹into› every kind of adapted structure into the gaps ‹of› in the œconomy of Nature, or rather forming gaps by thrusting out weaker ones. «The final cause of all this wedgings, must be to sort out proper structure & adapt it to change.—»

These two pages from the third of Darwin’s ‘Notebooks on the Transmutation of Species’ give us a window into another crucial moment, for here we see Darwin’s profound excitement as he responds to reading Malthus’ Essay On Population. Visually, I have always been struck by Darwin’s uncharacteristically small, yet very well formed, handwriting here. And notice how there seems to be at least two layers of writing. Indeed the pages are so densely packed that in some places scholars have difficulty cleanly separating the layers.

But, what is Darwin saying?  Well, you need to know that by September 1838, Darwin was deeply engaged in what became the two branches of his life’s work. One branch was the constant weighing of the evidence for and against evolution, though by March 1837—so about six months after the Ornithology Notes, he was convinced that the mutability of species was the way nature is organized—evolution is a correct theory. The other branch was Darwin’s search to define mechanisms that explain two things: how species acquire adaptations and how new species are formed.  In these two pages Darwin is, for the very first time,  beginning to formulate the essence of the mechanism for adaptive evolution, namely: by natural selection. No wonder he writes with so much energy, and yet with so much precision. What he does here is grasp the power of Malthus’ population pressure—‘the energetic language of Malthus,’ which he then harnesses as a natural agent that through the differential survival of the fittest—‘forming gaps by thrusting out weaker ones’ can thereby ‘sort out proper structure & adapt it to change’. This is the essence of natural selection. Not the  grown tree in full bloom. But it is more than just a seed, for if theories are like trees, at this stage Darwin’s was a healthy sapling.

Voilà! Evolution by Means of Natural Selection

Portrait version of the Biodiversity Heritage Library logo.

Exploring Darwin’s Journey Towards the Theory of Evolution,

Part 2 (View Part 1)

In our previous post, David Kohn, Director of the Darwin Manuscripts Project, discussed two Darwin manuscripts illustrating the development of his theory of evolution: excerpts from “Ornithology Notes” and his “Transmutation Notebook D.”

In this installment, we explore two additional manuscript excerpts: “Principles of Divergence” and Darwin’s “Origin Manuscripts.”

Celebrating Darwin Day. By David Kohn. Director, Darwin Manuscripts Project, Part 2

Principle of Divergence. Natural Selection Portfolios II

(Cambridge University Library, DAR 205.5: 148 http://darwin.amnh.org/viewer.php?history=&eid;=21139. For the whole of DAR 205, Darwin’s divergence portfolio, see http://darwin.amnh.org/viewer.php?mid=143)

Principles of Divergence Portfolio. Pg. 148. Cambridge University Library.

Darwin finished his last notebook in 1839 and waited until 1842 to write a first short essay and until 1844 to write a much longer essay. Then it isn’t until 1854 that he returned in earnest to work on what became the Origin, published in 1859. There are many reasons for all these obvious intervals and gaps. But let’s focus on one big reason, namely: as a comprehensive explication of evolution, the theory even in 1844 was incomplete. For all that Darwin had fully worked out natural selection—which explains the origin of adaption—between 1838 and 1842, yet we can see in retrospect that natural selection wasn’t sufficient to explain how new species are formed. Nor did natural selection explain the principle behind the irregularly branched tree of life that Darwin first drew back in 1837.  According to his autobiography, this big intellectual gap did not dawn on Darwin until the 1850s.

I overlooked one problem of great importance; and it is astonishing to me, except on the principle of Columbus and his egg, how I could have overlooked it and its solution. This problem is the tendency in organic beings descended from the same stock to diverge in character as they become modified. That they have diverged greatly is obvious from the manner in which species of all kinds can be classed under genera, genera under families, families under sub-orders, and so forth; and I can remember the very spot in the road, whilst in my carriage, when to my joy the solution occurred to me; and this was long after I had come to Down. The solution, as I believe, is that the modified offspring of all dominant and increasing forms tend to become adapted to many and highly diversified places in the economy of nature.  (Autobiography 120-121)

What intrigues me about this explanation of how the principle of divergence originated is Darwin’s memory of ‘the very spot in the road, whilst in my carriage, when to my joy the solution occurred to me’.  Did this really happen? Did he have a eureka moment riding in his carriage? For good reason, historians don’t like to trust autobiographical accounts. Darwin’s memory has been proven inaccurate more than once. And yet, let me rush in where wiser scholars may fail/fear to rush. In Darwin’s Natural Selection Portfolios II, there is a series of 15 loose notes, all related to divergence, all dated October to November 1854, and all written on identical grey paper. But one of these notes is written in pencil rather than ink. Unlike any of the other notes in the 1854 series, Darwin’s hand writing here is exceedingly ‘jumpy’.  Could this be the manuscript record of the carriage ride? The text reads:

We include all in class, as «in» Crustacea, which are connected, but yet no definition will define, — a proceeding explicable on descent.—

I suggest that this passage parallels the bolded sentences above from the Autobiography.  What I’m proposing as the carriage-ride note is a succinct statement of the problem or challenge of divergence—how to make the apparent “connectedness” of “all in class” more than just “heraldic”, but actually “explicable” on descent. The succeeding flood of grey-paper notes contain elements of Darwin’s solution—that is, the principle of divergence, which probably began to come into focus for him after he stepped down from his carriage. I think in this scrap of paper, we’ve again caught Darwin in the act of being Darwin.

Surviving draft manuscript sheets of the Origin of Species

(American Philosophical Society Library, BD 25.57 and Cambridge University Library, DAR 185: 109a (6v). For the entire known collection of Origin sheets see http://darwin.amnh.org/viewer.php?mid=2.)

Origin Manuscript. Pg. 224. American Philosophical Society Library.

The first edition of the Origin is a book of 490 pages. So Darwin’s hand-written draft must have been a respectable pile of paper. Yet for all the voluminous size of the Darwin archive, only some 30 sheets of the Origin survive. Happily, my favorite passage in the book is one of the five sheets owned by the American Philosophical Society Library in Philadelphia. Here is the passage:

Natural selection tends only to make each organism as perfect «as», or slightly more perfect than, the other inhabitants of the same country, with which it has to struggle for existence. And we see that this is so in nature.

This comes from Chapter VI, entitled ‘Difficulties on Theory,’ which perhaps could be more aptly called ‘Difficulties Conquered.’ The difficulty Darwin sought to overcome here was the appearance of perfection in nature, a concept invoked in the natural theology that Darwin encountered as a student in the work of William Paley. I am drawn to this passage because here Darwin pursues a metaphysical implication of his theory. He argues, rather slyly, that natural selection undoes the prevailing view that adaptations are perfect. He does this by introducing a contradiction in terms. How can anything be ‘slightly more perfect’. Perfect should be perfect. But Darwin shows that the concept of natural selection makes perfection relative. To be adapted organisms need only be ‘slightly more perfect than, the other inhabitants of the same country.’ But that renders perfection in nature a baseless and useless idea.

Finally, let’s consider one of the reasons that so few Origin sheets have survived. This picture on the back of an Origin sheet in Cambridge University Library is one of several with drawings like this one showing a battle between soldiers, who we may call knights of the aubergine and the carrot. The artist was Darwin’s son Francis, who evidently was given access to pages from the manuscript version of the great book. Indeed the manuscript only survives because Francis used it for drawing paper. His father didn’t seem to care!

BHL Book Highlights for International Rabbit Day

Portrait version of the Biodiversity Heritage Library logo.

“Promoting the protection and care of rabbits, both domestic and wild,” Saturday September 28 is International Rabbit Day and we couldn’t think of a better way to celebrate the Leporidae than to highlight some of our favorite literature about rabbits from the BHL collection.

View Full Size Image
Pl. LX from Johnson’s household book of nature

From our Darwin’s Library collection, a virtual reconstruction of the set of the surviving works held in Charles Darwin’s personal library, “The rabbit book” outlines the history of the rabbit, its varieties at the time, and provides instructions for their care and breeding. While a relatively quick read on such topics as the difference between rabbits and hares, treating dropsy (edema), and establishing a proper rabbit “court,” the most striking aspect of the book is its drawings of rabbit varieties from Angora to Full-lop. Check out our flickr image set of “The rabbit book” to see them all together.

Previous blog posts highlight another fantastic work about the Leporidae, James E. Harting’s “The Rabbit” (1898), as featured in our 2011-Year of the Rabbit post and Laurel Byrnes’ discussion of how the young Beatrix Potter’s love of natural history and study of rabbits inspired her famous children’s work, The Tale of Peter Rabbit (1902).

Want to cozy up with a few more selections of Lepus literature from the BHL? See our burgeoning list of articles related rabbits and hares and a variety of works that mention the genus, and the many species of this group, via our taxonomic search functionality.
