In this
course we will explore one of the most controversial questions of our
times: the economics of the environment. To do so we begin with radical
definition of terms and key concepts. By radical I mean root meaning.
Before doing so, however, it is appropriate to locate 'environmental
economics' within Economics as a discipline. I direct your
attention to

Definitions: Economics, Ecology & Environment
I begin
with literal definition of the three titled terms and then expand them
into their contemporary context. Economics derives from the Greek
meaning ‘management of the household’. Ecology derives from the Greek
meaning ‘life in and around the household’. Environment derives from
the old French meaning “the objects or the region surrounding anything”
or, alternatively “the conditions under which any person or thing lives
or is developed; the sum-total of influences which modify and determine
the development of life or character”.
Economics
Economics
as management of the household raises the question: What is the relevant
household? In its original sense it was the self-sufficient or autarkic
rural estate. Management, however, ascended to higher orders as the
self-sufficient village, town, city and most recently the Nation-State.
A global society in which there is contiguous urban development
separated only by natural barriers – mountains, oceans and deserts - has
been called the Ecumenopolis – the World City - by urban planner
Constantinius Doxiadis;
its global reality is visible in a composite photograph of “The
World at Night”
published by NASA in the year 2000. If seeing is believing then it
provides visual evidence of humanity enframing its home planet. We see
a World City whose shimmering lights soar out into the infinite
blackness of space. However, there is no global economics, no generally
accepted model for managing the planet.
As a modern
discipline of thought Economics began with the French Physiocrats
portraying the Nation as a giant estate in which the surplus required
for growth and development came from agriculture – one planted seed
yields 1000, that is productivity. The Physiocrats, however, lost their
heads to Madame Guillotine during the French Revolution and the locus of
Economics shifted to England, to Adam Smith and to the surplus generated
by the division and specialization of labour in manufacturing. The
paradigm shifted from biology to mechanics. We will apply the resulting
model - ‘X’ Marks the Spot - in Part 2.0 Environmental Economics.
Ecology
With
Ecology defined as the study of ‘life in and around the household’ we
leave mechanics for biology. The world according to theoretical biology
is composed three spheres: (i) the geosphere, the world of physics and
mechanics; (ii) the biosphere, the world of biology or life; and, (iii)
the noösphere, the world of human thought. To Aristotle, there were
four causes: material, efficient, formal and final. In this regard it
is important to recall that
Aristotle
was a biologist, not a physicist. Arguably, the geosphere is governed
by material and efficient causes, i.e., when-then or
billiard-ball causality. In the biosphere, however, formal and final
causes or ‘causality by purpose’ is at work while in the noösphere of
human thought arguably all four are at play.
There were
three aspects of living things that demonstrated to the philosopher
Immanuel Kant
that teleological or final causes were involved. I call these: ecology,
metabolism and ontogeny. First, he could see that the web of mutually
supportive relationships between various species of plants and animals
constituting an ecological community was so complex that linear
‘when-then’ causality was simply insufficient to explain its existence.
Second, in the metabolism of living things each part is reciprocally
means and end to each other. This involves a mutual dependence and
simultaneity that is difficult to reconcile with ordinary causality.
Third, in ontogeny, or development of the individual, the future mature
end-state guides successive stages of development. This is a clear case
of formal and final cause.
Ecology
involves not just the web of mutually supportive relationships in a rain
forest or the Arctic. It involves you and I. To drive the point home
but to avoid the digestive example of ‘Montezuma’s revenge’ I ask those
wearing short sleeves to take their thumb and touch the inside of their
elbow. There you will find some 182 species of microbes. In fact a
whole new science is emerging: the human microbiome involving the study
of all the microbes that live in and on people. Given that human beings
depend on their microbiome for essential functions including digestion,
a person is really a superorganism consisting of one’s own cells and
those of all associated symbiotic bacteria. In fact, bacterial cells
outnumber human cells by 10 to 1, meaning a person is, in a sense, a
minority in one’s own body.
Following
Marjorie Grene,
mother of the modern philosophy of biology, every organism lives in an
active environment consisting of: (i) invariants, e.g., the
river, the ocean, the sky, the mountains, the seasons, etc., and,
(ii) affordances presented by predator, prey, possible mates and/or
symbionts. Environmental invariants become subsidiary or ‘tacit’ to
focal awareness of affordances. In this view, ‘knowledge’ is
orientation in an environment resulting from tacit integration of
subsidiary and focal awareness into a gestalt whole called ‘knowing’.
While Darwin identified ‘survival of the fittest’ modern biology has
identified coevolution as a dominant force at play. Thus the humming
bird’s bill evolved to perfectly match the orchid’s blossom.
Environment
Environment
as “the sum-total of influences which modify and determine the
development of life…” is a much looser concept. On the one hand it
refers to all that surrounds us as individuals and as a society
including the geosphere and biosphere as well as the human built
environment of which more below under Technology. On the other hand
Environment often refers to Nature untouched by human hand. This
romantic view arguably dates back to
Jean-Jacques Rousseau
whose work heavily influenced the French Revolution of 1789 as well as
Western art and literature ever after.
Arguably
the modern environmental movement was born
with publication of
Silent Spring
by Rachel Carson in 1962. Carson identified the unintended consequences
of DDT. Intended to control insect pests infesting agricultural crops
and transmitting diseases like malaria and yellow fever, DDT
unintentionally thinned the shells of bird’s eggs resulting in a
dramatic decline in their population threatening a ‘silent spring’.
This highlights two critical aspects of environmental studies. First,
human actions can have unintended consequences on the environment that
surrounds us. Second, it is only with new knowledge that such
consequences can be recognized. Thus ‘ignorance’ defined as the absence
of knowledge can be cured but as the old saying goes: Knowledge will set
you free but first it will hurt you!
1.2 Concepts
Four
critical concepts need to be established before exploring the economics
of the environment. These are Technology, Ideology, Price and Value
Theory.
Technology
The word
‘technology’ derives from the Greek techne meaning Art and
logos meaning Reason, i.e., reasoned art. In its modern
sense the term was introduced in 1859 by Sir Richard Francis Burton,
Victorian explorer and translator of the Kama Sutra, the
Arabian Nights and the Perfumed Garden. Techne,
however, dates back to the ancient Greeks for whom it signified all the
Mechanical Arts except medicine and music. As such, it was suitable
only for the lower classes not for the upper class which practiced the
Liberal Arts of ‘free’ men. It was thus in ancient Greece that the
English aphorism ‘gentlemen don’t work with their hands’ had its
beginning.
Before 1859
there was art, craft and mechanics; afterwards, technology. While early
attempts were made to formulate philosophies of mechanics, they remain
footnotes in history including Ernst Kapp who in 1877 coined the term ‘philosophy
of technology’.
It was, however, Karl Marx who ten years earlier produced the first true
philosophy of technology
with his Das Kapital combining ‘the means of production’ with a
critique of a rapidly industrializing society.
Martin
Heidegger, however, is in fact the father of the post-Marxist or modern
philosophy of technology (1954).
Technology enframes and enables Nature to serve human purpose. This is
not just a technological imperative, it is also a biological one.
Organisms do not simply adapt to the environment. Many actively adapt
and modify it to satisfy their needs, e.g., the ant, bee and
beaver. This involves constructing new environmental invariants,
e.g., colonies, hives or lodges.
Of all
organisms on Earth, humanity has had the greatest success in
re-structuring its environment. Tools, specifically the
tooled
knowledge
they contain, are the means by which we animate and re-organize Nature.
In effect, Technology constructs a distinct human ecology growing ever
more distant from Nature as our knowledge grows. Consider coming home
from the office in a car, unlocking the door to the house, turning on
the lights, microwaving supper, watching television, checking one’s
email then driving to the local mall to shop. All is technology. It
enframes and enables Nature to serve human purpose.
Ideology
The word
‘ideology’ has many meanings today but was coined simply enough by
Condillac, a contemporary of Adam Smith, to mean ‘the science of
ideas’. Separation of Church and State was critical to both American
and French Republican Revolutions. Creation of a secular ‘science of
ideas’ to counter the awe and mystery of religious and metaphysical
thought and ritual was part of a revolutionary agenda designed to
overthrow an Ancient Regime of subordination by birth. In short an
Ideology explains how the world works without a god; with a god it becomes theology.
In this regard the word ‘theory’ literally means
a god’s eye view.
It is important to
note, however, that Ideology involves, as will be seen below, ‘the
sciences of the artificial’, the so-called human sciences which are
subject to human, not natural laws. The natural, experimental,
instrumental sciences are different. They are subject to the laws of
Nature and rather than generating certainty or belief in fact generate
doubt - no theory can be proven right but can be proven wrong. The
philosopher of science Michael Polanyi (1961)
noted:
To hold knowledge is indeed always a commitment to
indeterminate implications, for human knowledge is but an intimation of
reality, and we can never quite tell in what new way reality may yet
manifest itself. It is external to us; it is objective; and so its
future manifestations can never be completely under our intellectual
control.
In fact Descartes’ famous dictum ‘I think, therefore I
am’ could more accurately be restated as ‘I doubt, therefore I am’. By
contrast, a contemporary definition of Ideology is: A systematic scheme
of ideas, usu. relating to politics or society… and maintained
regardless of the course of events" (OED, 4).
If
Technology cum Heidegger enframes and enables Nature to serve
human purpose then Ideology enframes and enables our ideas, our
thoughts. An Ideology becomes subsidiary to our focal consciousness, it
becomes an environment invariant for the affordances of our thoughts.
It becomes background to the figure of our ideas.
With the
collapse of Communism there is arguably only one Ideology still standing
- Market Economics in which everything has a price – kidneys, children,
the environment, everything. It is, however, arguably split into two
antagonistic schools of thought. One, the Austrian School of the ‘vons’
- von Mises &
von
Hayek,
believes in the supremacy of the market with limited if any public
intervention. With respect to the environmental problems discussed
in this course the Austrians would say: If consumers are willing
to pay to fix such problems, the market will respond. If not they
still get the world they want.
On the other hand, the
Keynesian School,
believes in a regulated marketplace and public intervention to correct
market failures and produce an appropriate level of public goods. Both are ideologies, not natural science.
Price & Value Theory
The
question of the value of goods and services is a perennial in
Economics. For Aristotle and St. Thomas Aquinas it was the problem of
the ‘just price’. Should it reflect: (i) usefulness; (ii) scarcity;
(iii) the labour required to produce it; (iv) the combined cost of all
inputs including capital, labour and natural resources; or, (v) whatever
the market will bear? Today one might added the environmental impact of
its production and/or consumption. This constitutes Value Theory.
Price
Theory, on the other hand, accepts the market as the determining
factor. Price is established through interaction of supply and demand
under different market structures including perfect competition,
monopoly, monopolistic competition and oligopoly. This constitutes the
‘X’ marks the spot model of market economics which will be examined in
greater detail in 2.0 Environmental Economics. In fact Price Theory is
a subset of Value Theory in Economics.
1.3
Measurement: Natural vs. Sciences of the Artificial
In the 6th
century before the common era Pythagoras discovered a cognate
relationship between number and matter, e.g., pluck a string and get a
whole tone, pluck a half string and get a half tone. Since that time to
count or measure a phenomenon in numbers has acquired the aura of truth
especially in Western civilization – I have the numbers!
Since the
beginning of Western civilization, logic has been accepted as the
preferred path to knowledge. It distances us from our passions; it
frees us from the distracting world of sensation and emotion. In the
hands of the Romans the Greek logos became ‘reason’ derived from
the Latin ratio as in to calculate (OED, reason, n 1). And from the
Romans we derive Science from the Latin scire “to know” which, in turn,
derives from scindere “to split” (MWO). Natural science today is
accepted as the epitome of reason deriving knowledge by splitting or
reducing a question into smaller and smaller parts or elements until a
fundamental unit or force is revealed. Until innovation of the
experimental instrumental scientific method, however, such splitting and
reducing was restricted to words.
The
unprecedented evolutionary ascent of our species to global dominion,
achieved in some twenty-five generations, arguably resulted from the
institutionalization of a new way of knowing, a new way of generating
the numbers - the experimental method, or, as originally called,
‘experimental philosophy’. Developed by craftsmen of the late or High
Middle Ages of the Western European civilization, it was first fully
articulated by a late Renaissance genius, Sir Francis Bacon in his Of
the Proficience and Advancement of Learning Divine and Humane,
published in 1605.
According
to Bacon, human dominion was to be achieved by reducing Nature’s
complexity through instrumentally controlled experimental
conditions forcing her to reveal her secrets. She did. The question
was first put using instruments developed in the craft workshops of the
European Age of Discovery. It was here that Bacon saw the prototype of
his ‘House of Solomon’, the house of wisdom and of knowledge. He called
on scholars, practioners of the Liberal Arts, to come down from their
ivory towers and test Nature in the workshops of the Mechanical Arts
where, in his time, the necessary instruments were available. He also
called for a History of the Trades to provide scholars with an
understanding of the findings about Nature made by the rapidly advancing
Mechanical Arts, e.g., ballistics, metallurgy, navigation, ship
construction, etc. In this regard, Galileo’s research was in
part funded by what today would be considered military contracts.
Reductionism has, however, a significant advantage. It strips away
secondary phenomena distinguishing cause from effect revealing, in the
natural sciences underlying ‘laws of nature’. Its metaphysical
legitimacy rests on the testing of cause and effect, or when-then
causality with Time’s Arrow moving out from the Past into the Present
and then into the Future by way of prediction.
Reductionism also
has its limitations especially in questions of biology and environmental
sudies. In such cases it is not sufficient to take things apart
but rather to discover how they work together. Arguably this is
one reason why things questions like climate change are so
controversial. It is the interaction many, many factors that drive
climate. Reducing them one by one does not explain how it works.
In fact we are the beginning of a new scientific revolution and out
tools and understanding is at its beginning.
Experimental instrumental science is, in fact, an organized and
routinized pattern of human behaviour, an institution that has been
called ‘The Republic of Science’ (Polany 1962b). This pattern, however,
crystallized only very recently (about four hundred years) and remains
fragile. Nonetheless it has been incredibly productive in generating
knowledge about the geosphere and biosphere, if less productive with
respect to the noösphere. Arguably, its success can be attributed to
three factors.
First
is the Pythagorean Effect, i.e., exploitation of the cognate
relationship between mathematics and the world of matter and energy.
Second is the Instrumentation Effect, i.e., scientific
instruments generate evidence not requiring intermediation by a human
subject and provide readings at, above and below the threshold of the
native human senses. Once calibrated and set in motion a clock – atomic
or otherwise – ticks at a constant rate per unit time until its energy
source is exhausted. In effect, this lends metaphysical legitimacy.
Scientific instruments realize the Platonic “belief in a realm of
entities, access to which requires mental powers that transcend sense
perception” (Fuller 2000, 69). Furthermore, the language of scientific
sensors realizes another ancient Greek ideal, that of Pythagoras, by
reporting nature by the numbers. Third is the Puzzle-Solving
Effect of paradigmatic ‘normal science’ (Kuhn 1996) which permits
vertically deep insight into increasingly narrow questions, i.e.,
depth at the cost of breadth of vision.
The Human
Sciences or Humanities & Social Sciences (HSS) are called ‘sciences of
the artificial’ by economist Herbert Simon. The natural, experimental,
instrumental sciences are subject to the laws of Nature. The sciences
of the artificial, on the other hand, are subject to human not natural
laws. In addition, objective instrument-generated evidence
distinguishes the natural & engineering sciences (NES) from the sciences of the artificial in which human
mediation contaminates every stage of the evidentiary trail. Change one
law and the profit maximizing formula must be re-calculated.
The limited
success of the HSS in generating new knowledge compared to the NES can
be attributed to the absence of the Pythagorean, Instrumentation and
Puzzle-Solving Effects noted above. First, while there may be
some relationship, there is no apparent cognate relationship between
mathematics and human behaviour. Second, HSS evidence – in its
collection, compilation and analysis - is subject to intermediation by
human subjects all along the evidence trail, limiting objectivity.
Third, with the pedagogic exception of economics and its Standard
Model, there is no generally accepted paradigm in any HSS discipline
corresponding to ‘normal science’ that, according to Kuhn, is required
for efficient puzzle-solving. In short, numbers have parents. In the
Natural Sciences those parents are instruments; in the sciences of the
artificial, they are people with their own prejudices and agenda.
1.4 How Did We Get Here? Harold Innis’
Staple Theory
The text
speaks of dynamic and static efficiency but does so essentially outside
of history, disembodied from context. How did we get here? Harold
Innis is arguably the founder of the only indigenous school of Canadian
economics based on his ‘staple theory’. He studied Canada’s development
- from cod to fur to timber to wheat. Each staple, according to Innis,
engenders a distinctive patterning to the economy. Arguably
manufacturing became the next staple in Canada’s development. In
turn it began and continues to be rooted in consumption of fossil fuels. Near the
end of his career, however, Innis moved on to ‘communications’ and its
matrix concluding, in effect, that it is the ultimate staple commodity (Innis
1950, 1951). His student and colleague, Marshall McLuhan extended Innis’
work formulating the saying: The Medium is the Message.
We are now
in what is called a knowledge-based economy in which the staple is
intellectual property rights including statutory property such as
copyrights, patents, registered industrial designs and trademarks as
well as contractual property such as ‘know-how’ and trade secrets. It
too demonstrates a distinctive patterning of the economy. This includes
an enhanced ability to identify unintended consequences of human actions
including those with environmental impact.
