This
post should have two beginnings. Here's the first. I think the one
basic thing a university should do for each student, regardless of his
or her chosen program, is to teach them to think about how they think.
Particularly now, when social media has become a conduit for
misinformation--often vicious misinformation--we all need to query how
we know what we know: whether this fact conforms to that truth; whether
this tweet simply confirms we we have always believed about
immigration, race, hatred, inequality, or whether it offers some new
insight that challenges our beliefs. Because I have always believed
this, I often began my classes with a small history the enlightenment
project, which began, some believe, with Descartes' pronouncement "I
think; therefore I am," or with the publication of Isaac Newton's Principia Mathematica.
Perhaps the easiest way to think about this shift is to think about the
replacement of lore with experiment. Living in a world that God had
graced with meaning, we thought we could safely assume that occasionally
He sent us helpful messages in the structure of the world around us. A
plant whose leaves look like lungs was thus named lungwort and was
thought to be helpful when a patient was having difficulties with his
lungs. But with the Enlightenment project, which challenged the
authority of both church and aristocracy, the individual becomes the
source of truths. That individual is challenged to ascertain, through
experiment or close observation, the truths she stood behind. And the
individual is given this authority through belief in liberty and through
the separation of church and state. It's hard for me to say which came
first, liberty or experiment, but one can see that they need to exist
in tandem for the individual's observations to be freely undertaken and
given credence. Almost three centuries later, these notions remain
rather abstract for students.
So let me begin again. I
have been working on some poems about the natural world, poems that seek
to do two things. One is to assume that the natural world has its own
culture. I'm trying, then, to encourage the reader to see nature
differently--not less than our "civilized" world with its free markets
and its technology, but parallel to it in ways that we all benefit
from. The second is to make these poems as crystalline and transparent
as I could--simple, almost, though not simplistic. This project was
not, however, going to make a whole book, so when I serendipitously ran
across Andrea Wulf's biography of the great nineteenth-century
naturalist, Alexander von Humboldt, I fell down a rabbit hole. What if I
were to balance my idiosyncratic observations about nature's culture
with poems about the work of naturalists--running from Linnaeus and
Gilbert White to Catherine Parr Traill and Rachel Carson?
Characteristically, I began reading in a landscape I knew, devouring
Thoreau's Walden and his volumes upon volumes of journals, or with
Whitman's thousands of pages of Specimen Days. How was I
possibly going to find the moment, the detail, the point of illumination
that opened Thoreau's or Whitman's ideas up to the reader, teasing them
in the way some orchids tease in their pollinator? It turns out that I
have found one of these for Whitman--his assertion that he can hear
spring. And as Thoreau's journals turn from a kind of philosophical
meditation on the natural world to rigorous walks to discover what
nature is doing today, the question "how long?" rings again and again,
as he wonders how long this shrub or this flower has been blooming.
But it was a review of Tim Birkhead's The Wonderful Mr Willughby: The First True Ornithologist
that took me right back to the front lines of the Enlightenment and
helped me start my reading in a sensible place, though it is clear to me
that I have a lot of wonderful, hopeful reading to do. What can be
more hopeful than scientists' efforts to understand the natural world,
which seems in many ways shaped for human thriving yet beyond our
understanding? If you don't mind, I'll take you on my journey, and as I
write about these scientists I can come closer to the moment in each of
their lives that will open into a poem.
As a young
Cambridge-educated man of some means, Francis Willughby and his closest
friend and tutor, John Ray, undertook (along with Philip Skippon and
Nathaniel Bacon) a different kind of Grand Tour of the continent in
1663. Their stops included botanical gardens, apothecaries' shops--full
of cabinets of curiosities, medical and otherwise. In Venice, they
frequently visited the market where birds were sold and returned again
and again to the fish market. And here is where we see the difference
Mr Willughby made.
"The key to the new science was the
organisation of knowledge," Birkhead tells us. "Although the scientific
revolution sought to overturn much of Aristotle's thinking, it was, at
the same time, based on two fundamental Aristotelian assumptions.
First, that there was order in nature." I'm inclined here to
say--again--that everything is political. Willughby and Ray, along with
other Britons, had seen the British Civil War as chaotic. Birkhead
writes of the connection between science and politics, "Order was
uppermost in many people's minds. The Civil
War had created monumental and awful disorder, so consciously or
unconsciously the quest for order was paramount and classification and
quantification became the foundation of the new science" (46). Many
seventeenth-century scientists believed that their task was to uncover
or reveal God's order, which was manifest in the natural world. The
Enlightenment thus fostered much "citizen science." But what to do with
Francis Willughby's discovery of a buzzard unlike any seen before in
England--besides name it "Willughby's Buzzard"? Under the protection
of Charles II, the Royal Society was created and dedicated to the
discovery, organization, and dissemination of knowledge. As well,
Patricia Fara argues in her provocatively title Sex, Botany, and Empire,
the second task of the Royal Society was to spread the idea of
empirical thinking throughout Britain. Unfortunately, there was a dark
side to this massive effort to create fuller knowledge of the natural
world: we can't ignore the fact that many of the journeys taken to gain
knowledge of, say, Tahiti or Australia, were also meant to enlarge the
British Empire.
But what we don't quite
understand, outside of a biography like this one, is the set of
challenges that created barriers to apperceiving such an order. First:
names. Most birds had names that were largely local, so Willughby and
Ray were going to need to create the name. Second: sex. Quite
often, as Willughby and Ray proceeded, they found that a new species
theorized by an amateur ornithologist was really just the female of
another species.
The second Aristotelian principle is the idea that an organism had an "'essence' -- what made it it" (45).
And discovering what made a creature itself was going to involve
shooting a lot of birds and dissecting them. What Willughby and Ray
contributed to the knowledge of birds was careful observation. Before a
dissection, Willughby patiently described myriad details of a bird's
appearance, right down to the colour of eyelids or whether they had
hairy toes, the number of feathers on a wing or a tail. Dissection
would tell them whether they had a male or female, of course. But they
also observed, for example, the length of the digestive tract, finding
similarities between birds otherwise not recognized.
Willughby
returned to England, settled down, eventually married, though only four
years before his premature death. At that time, he left John Ray to
complete the Ornithology and two other books on fish and insects. The Ornithology
was very successful, largely because of Willughby's careful and precise
descriptions and because of the engravings that helped a birdwatcher
identify a bird--though being black and white and being copied from
paintings, they were not as useful as they might have been. But "Ray's Ornithology,"
as it came to be called, published in Latin in 1676 (making it
accessible to scientists who did not speak English) and in English in
1678, contributed much to the knowledge of birds and set a new standard
for scientific writing. This was not only due to the careful
observation and precise descriptions that Willughby provided. When other
writers of the time needed to flesh out areas beyond their own
expertise, they often simply plagiarized from other books on birds,
keeping errors and mistakes in circulation. More than one mythological
birds endured because writers plagiarized from one another.
Birkhead
talks exuberantly about coming on the Willughby family archive and
finding a cabinet of curiosities that still held eggs labelled in
Willughby's hand. But there is an enormous gap in the archive insofar
as it contains little of Willughby's own writing--the diary he kept
while on his tour of the continent, for example. His voice only lives
in a handful of questions he left behind him. He wanted to know about
the smallest distinct features of birds, like the tomial tooth--a "hook
on each side of the upper mandible" or the varied colour of irises of
birds like the petrel and the albatross. Willughby and Ray's attention
to such details and their ability to see a pattern in them led them to a
classification system that Birkhead calls "ingenious and
effective"--far better than anything Linnaeus proposed. Though they did not ask why birds had a tomial tooth or a long digestive tract. that would come later.
Willughby
also wanted to know about why some birds lay more hens than
cocks--which only reveals his inability to distinguish between
nature--which dictates that there are about as many hens as cocks--and
culture, which eliminates too many cocks in a henhouse. He wanted to
know why some cocks had large testes, and intuited what we now know:
that in birds who are inclined to be promiscuous, the cock needs to
produce more sperm. He wanted to know "What birds hide themselves or
change places, whether in winter or summer" (201) There were all kinds
of theories about what birds did to remain alive during the winter,
including Linneaus's silly theory that swallows spent the winter
hunkered down in mud. Questions about the migrations of birds remained
an issue in 1789 when Gilbert White published his wonderful book--never
out of print--The Natural History of Selborne. It would be
several hundred years more before we learned that black-capped
chickadees and hummingsbirds drop their internal temperatures on winter
nights so they have sufficient fat to keep them alive (200). In
scientists' struggle to understand how birds adapt to harsh
environments, whether they migrate or enter torpor or mini-hibernations,
we come across a kind of problem that the Enlightenment struggled to
solve: how do you understand what isn't there, what you can't see?
