Introduction

In the second chapter of Genesis we read that “out of the ground the LORD God

formed every beast of the field and every bird of the air, and brought them to

the man [Adam] to see what he would call them; and whatever the man called

every living creature, that was its name” (Gen. 2.19 RSV). Jewish and Christian

theologians have traditionally interpreted this oft-quoted passage to mean

that God thereby gave man (still without a wife, but shortly to have one) dominion

over nature. Humans thereafter legitimately possessed the right to control

the natural world and to exploit it for their own use. Those concerned with

the origins of the current environmental degradation view that dominion with

considerable ambivalence, and some cite this alleged transfer of authority as a

root cause of the attitudes responsible for our long history of mismanagement

of global resources.

Less controversial, but equally significant, the Genesis story also reflects the

long-standing importance of naming and characterizing things found in nature.

That one of Adam’s first tasks consisted of naming animals should not

surprise us. We all possess a curiosity about the natural objects on Earth—animals,

plants, minerals—and for good reason; they are a source of food, medicine,

clothing, shelter, and entertainment. Anthropologists, who study different

cultures of the world, find that all peoples name and categorize the objects

in their environment. And most, if not all, cultures share commonsense ways

of conceptualizing the natural world. The simple notion that living things that

fly constitute a natural group, for example, is shared by second-graders in Colorado

and village elders in southeast Asia.

Naming and categorizing has concerned humans since ancient times, as the

Hebrew texts attest. Whether for the most basic requirements of communal

life or for the most sophisticated scientific exchanges, we have wanted to communicate

information that we have gained about the world. Starting in the

eighteenth century, however, a particular approach to this activity emerged as

a scientific discipline in Europe and has continued to the present day, the modern

tradition of natural history. What distinguishes natural history from the

“folk biology” of earlier studies is the attempt of naturalists to group animals,

plants, and minerals according to shared underlying features and to use rational,

systematic methods to bring order to the otherwise overwhelming variation

found in nature. Although bats are living animals and fly, naturalists do

not consider them “birds” because bats share certain characteristics with other

mammals. Nor do naturalists consider a simple alphabetical list of animals a

viable option for classifying them, given the enormous number of known animals

(750,000 insects alone). Instead, naturalists have been working since the

1700s to document the natural world, systematically naming and organizing

the myriad forms found there, as they attempted to discern an underlying order.

Although individuals before the eighteenth century pursued similar goals,

no large-scale, sustained, and organized effort had existed until then.

In the discipline of natural history, researchers systematically study natural

objects (animals, plants, minerals)—naming, describing, classifying, and uncovering

their overall order. They do this because such work is an essential first

step before other, more complex analyses can be undertaken. We cannot start

discussing a wetland, or the interactions within it, until we know something

about what is there. Nor can we intelligently talk about the effect of an event

on a particular environment until we have a sense of the specific kinds of organisms

that inhabit it. Natural history does more, however, than just construct

catalogs and field guides, important as these are. It explores broader issues:

How do all the pieces fit together? What interactions can we discover?

What changes? What responsibilities does our knowledge confer upon us?

This book traces the fascinating story of the study of the natural world that

began in the eighteenth century and has since captured the interest of an everwidening

circle of enthusiasts. Eighteenth-century society lavished attention on

natural history. The second most frequently owned item in private libraries in

France at that time was the naturalist Buffon’s monumental 36-volume encyclopedia

of animals. Cultured gentlemen and ladies normally owned collections

of stuffed birds and of shells, with the size of their “cabinet” (as these collections

were called) often reflecting their wealth, taste, and level of refinement.

Interest in natural history, however, extended beyond what was merely

fashionable. Beginning in the 1700s and extending well into the 1800s, major

European powers engaged in a worldwide scramble to identify natural products

of economic importance. Prime ministers believed that the fate of empires

rested on identifying, cultivating, and transporting specific plants, such

as tea shrubs and rubber trees. Thomas Jefferson sent Lewis and Clark across

the North American continent in part to survey the economic potential of the

natural products in the newly acquired Louisiana Purchase.

While imperial rivalries sent soldiers and explorers to steaming jungles

and exotic highlands, a different but equally ferocious contest took place in

the western badlands of America. The quest for dramatic fossil skeletons, particularly

dinosaurs, captivated a generation of naturalists in the United States.

It resulted in a competition for bones in the 1800s that rivaled battles fought

among the Fifth Avenue “robber barons” over coal, iron ore, and oil. The public

found the Jurassic treasures fascinating. To illustrate the point one need

only consider that, by the early twentieth century, more people visited natural

history museums to see these prehistoric remains than attended football

games.

Natural history also provided the scene for competition among ideas. Conflict

between religious and secular views has often fixed on interpretations of

nature. Society on both sides of the Atlantic, for example, argued bitterly over

the implications of Darwin’s theory of evolution. For some the theory threatened

to undermine accepted religion; for others it opened up the possibility of

revitalizing what they took to be a declining and outmoded set of religious

opinions. As in the searing debates over slavery, families literally fragmented

because of conflicting positions on evolution. Respectable men hurled insults

at one another at nineteenth-century scientific meetings (on one occasion the

intensity of the discourse caused a woman to faint).

The story of natural history does not end with the heyday of museum attendance

early in this century or with the breakup of colonial empires. Problems

in today’s world drive current research in natural history. Much of the impetus

for earlier natural history arose from European exploration of exotic

regions of the globe. Recent development, primarily to stimulate economic

growth, has destroyed many of the sites, such as the coastal forests of Brazil,

that formerly lured naturalists from the comforts of home and drew them to

dangerous expeditions (from which many did not return alive). Naturalists

worldwide fear that the pace of development threatens irreparable damage to

these formerly pristine locales and to the associated rich diversity of animal and

plant life on much of the planet. Exploitation of tropical rain forests destroys

about 76,000 square miles per year—roughly the size of the entire country of

Costa Rica. Naturalists such as E. O. Wilson, who are deeply concerned about

the issue, point out that the problem is compounded by our lack of knowledge.

We are wiping out unknown species, and consequently we have no idea

of the potential value of what is now gone forever. Scientists, politicians, and

economists differ significantly on what actions should be taken to arrest the

loss of biodiversity. At international meetings, however, they do agree that, as

gargantuan as the task may appear, a first step would be to complete a basic in-

ventory of Earth’s species. The environmental, economic, political, and social

well-being of humans may depend upon the success of such initiatives.

In spite of natural history’s close tie to the pressing ecological and environmental

issues of today, science writers and other commentators in this

“high-tech” age occasionally treat the subject primarily as a beginning stage in

the investigation of the natural world; being a naturalist means merely to name

and describe things found in nature. They patronizingly treat natural history

as old-fashioned; a pastime that conjures up images of men in knickers carrying

butterfly nets or Victorian ladies with plant presses. Research into the history

of the discipline however, quickly dispels such a simplistic caricature. To

be sure, naming, describing, and classifying continues to be a basic activity that

serves as a foundation for the study of nature. The quest for insight into the

order of nature, however, leads naturalists beyond classification to the creation

of general theories that explain the living world. Those naturalists who focus

on the order of nature inquire about the ecological relationships among

organisms and also among organisms and their surrounding environments.

They ask fundamental questions of evolution, about how change actually occurs

over short and long periods of time. Many naturalists are drawn, consequently,

to deeper philosophical and ethical issues: What is the extent of our

ability to understand nature? And, understanding nature, will we be able to

preserve it? Naturalists question the meaning of the order they discover and

ponder our moral responsibility for it.

So, does natural history mean mere butterfly and flower collecting? Only

in the sense that Alfred Tennyson referred to when he wrote, in “Flower in the

crannied wall”:

Flower in the crannied wall

I pluck you out of crannies

I hold you here, root and all, in my hand,

Little flower—but if I could understand

What you are, root and all, and all in all,

I should know what God and man is.

In the eighteenth century Buffon and the Swedish botanist Linnaeus, along

with a number of other students of nature, established a coherent tradition of

natural history. We trace that tradition to see how it expanded and interacted

with other traditions in the life sciences, examining some of its major achievements

and considering its present state in the world of science. We note the

extent to which it reflected the culture of the times and to what degree it had

its own history. In exploring these topics we also examine the institutions in

which naturalists performed their research and the source of their funding. We

see how natural history has yielded the major unifying theory of the life sciences,

uncovered some of the deepest insights into nature, led to concern for

the environment, and attracted public interest for more than two and a half

centuries.

Fascination with nature led some naturalists to relinquish the comforts of

home for the hardships and danger of fieldwork; it drove others to spend days,

evenings, nights examining data. Indeed, this tradition has inspired, enlightened,

and delighted its practitioners and their audience.
