Big History of Our Planet Threshold 8

The Modern RevolutionBig History of Our Planet

– Threshold 8

The pay-off to lectures on early human history

• Fundamental trends in human history– Collective learning more information – Intensificationmore control over biosphere – Larger, denser populations – Increasing social complexity – Intensified collective learning acceleration in pace of

change increasing impact on biosphere

• We have also seen thresholds:– Agriculture, and perhaps state formation?– Now “the Modern Revolution”

Question to ponder

• What were the limitations of agrarian society?

• What made the Modern Revolution?

This Lecture: Thinking about Modernity

• Revolutionary:

– Transformative

– Fast!

• Hard to describe:

– We are in the middle of it

– We need a deliberately vague label!

The “Modern Revolution”or the “Anthropocene”

• Recent centuries sudden acceleration in human control of biospheric resources

– c.f. Agricultural Revolution, but much faster!

• Creates today’s world

• Eighth Threshold of Complexity

• My own ideas on modernity are changing!

The Modern Revolution as a threshold

• Fitting modernity into the big history story– Is today’s world the most complex structure we’ve

detected in 13.8 billion years?

• Similarities with earlier thresholds?– Do we see an increase in complexity?

– Do we see increasing energy flows?

– What new ‘emergent properties’ do we see?

– What ‘goldilocks conditions’ allowed the crossing of this threshold?

Re-thinking modernity

• Agriculture was transformative because of a sharp increase in energy flows more humans new types of societies

• I’m increasingly thinking the modern revolution is similar: fossil fuels provide the energy boost, transforming the world.

Since 1850: A Global Fossil Fuels bonanzaHow different would today’s world be without fossil fuels?

[From Alfred Crosby, Children of the Sun, p. 162]

• Each of us now uses, on average, 100 “energy slaves”[Buckminster Fuller]– They feed us, clothe us,

move us from place to place, carry messages

• The first species in 4 Billion years to mobilize more than a slight surplus over basic needs

• Most of the increase in the last 200 years

3 Main Parts to the Lecture

1. Describing the Modern Revolution

2. Explaining the Modern Revolution

3. Explaining the “Rise of the West”

Pt. 1: Key features of the “Modern Revolution”

• What is different about the modern world?

• 1) End of the Old World

• 2) Rapid Population Growth

• 3) Innovation & Growth

• 4) Transportation, Communications & Globalization

• 5) The power of states increased

• 6) Life experiences transformed

• 7) New modes of thought

• 8) Acceleration

1) End of the Old World: Worlds we have lost

Transformations in how people “made a living”

• From a world in which most people were self-sufficient peasants

– Living similar lifeways based on the land

– Producing most of what they needed at home

– Relatively self-sufficient

• To a world in which most people were wage-earners

– Living in very diverse ways, drawing incomes

– Buying most of what they need on markets

– Utterly dependent on each other

3) Innovation & Growth

• Remarkable acceleration in rates of innovation since 1700

• More energy & resources

• Larger populations

• Improved living standards

GDP per capita over 2 millenniaCE 0-1998 ($1900 US)

Based on Maddison, The World Economy: A Millennial Perspective, p. 264

Growth per cap in the Agrarian Era

Modern Growth depends partly on an Energy Bonanza

• Before the modern era, energy came from recently acquired energy from the Sun:

– Humans (slaves were stores of energy)

– Animals

– Biomass (e.g. wood fires)

– Wind and Water

• In the modern era, vast new sources found from older stores of energy:

– Fossil fuels (Coal, oil, natural gas), converted into Electricity

– Atomic power

A “big history” perspective on fossil fuels

Energy pours

from the sun into

surrounding

space

Fusion reactions

in the Sun’s core

generate energy

On earth, plants capture and

store some of that energy

Humans capture energy buried

100s of millions of years ago,

and fossilized as coal, oil, natural

gas

Learning to exploit Fossil Fuels:James Watt’s improved steam engine

Also 2 Types of Nuclear Power

• Left: Fission reactions split

large atoms (such as Uranium)

with unstable nuclei

• Right: Fusion reactions

imitate the sun, fusing

Hydrogen atoms into Helium

• The ‘Tokamak’ fusion reaction,

Princeton

• In 1993, it generated fusion at

temperatures 3 times those at the

center of the Sun

• The heat was contained by

powerful magnetic fields

4) Transportation, Communications & Globalization

Transportation

• Steam engines

• Steam ships

• Automobiles

• Planes

• Rockets

Information flows

• Telegraph

• Radio

• Phones

• Television

• Internet

Transportation: from the speed of a horse to a plane

Information: from the speed of a horse to the speed of light

These technologies transformed collective learning

5) The power of states increased

• More resources & larger populations

• More control over citizens’lives (e.g. compulsory education)

• More coercive power and larger armies (nuclear states have the power to ruin the biosphere in a few hours)

6) Life experiences transformed, e.g. …

• Urbanization:

– 1900, c. 10% in towns

– 2000, almost 50%

• Length and experience of Life:

– Average life expectancy rose by 2-3 times

– Interpersonal violence no longer acceptable

• Decline of Family:

– The key institution in all earlier eras

– Now less important for education, health, work

– Other institutions took over these functions

7) New modes of thought

• Sciencemore important

– Enabled humans to extract more resources from their environment

• ‘Magical’ thinking & ‘Animistic’ thinking less important

• Religion ceased to be the dominant mode of thinking

8) Acceleration

• Paleolithic Era significant changes over 1000s of years

• Agrarian Era significant changes over 100s of years

• Modern Era from week to week!

My generation more change than in the last three thousand years

3 Main Parts to the Lecture

1. Describing the Modern Revolution

2. Explaining the Modern Revolution

3. Explaining the “Rise of the West”

Agrarian Era:‘Prime Movers’ of innovation

Agrarian Era: 3 major drivers of innovation1. DEMOGRAPHY:

Population pressure innovation

2. EXPANDING EXCHANGE NETWORKS: collective learning

3. STATE ACTIVITY: Some government activities (e.g. road building) innovation

• These drivers could not generate enough innovation to keep up with population growth

• a) Malthusian cyclesb) Governments usually preferred to invest in military conquest

rather than economic growth

Modern Era:‘Prime Movers’of innovation

Modern Era: 3 other drivers of innovation become more important

1. COMMERCE & TRADE:

2. CAPITALISM: A new Social Structure

3. EXPANDING EXCHANGE NETWORKS

• Result? A threshold in innovation growth rates so fast:

1. That innovation has kept up with population growth end of Malthusian cycles (so far!)?

2. That governments & businesses find it worthwhile to invest in

real economic growth rather than conquest

Prime Mover 1: Commerce

• Adam Smith as markets expand, innovation increases

• Most modern economists agree

– Why? In competitive markets entrepreneurs must innovate to survive

• Yet:

– Commerce in all agrarian civilizations

– Why was its impact so limited?

– Because states weren’t controlled by merchants?

– We must also look at social structures

Prime Mover 2: Capitalism: A new Social Structure

Similar to Smith’s argument, but focuses on social structures:

• Karl Marx 2 models of society:

– ‘Capitalist’ social structures encouraged commerce and innovation

– ‘Tributary’ societies did not

Models of 2 Types of Societies

1. Tributary Societies (e.g. all agrarian civilizations):

– Elite groups extract wealth through ‘Tributes’: i.e. through the threat of force

– Power = key to wealth, not commercial skill

2. Capitalist Societies (e.g. most modern societies):

– Elite groups extract wealth through commerce & markets

– Selling cheap = key to success

– To sell cheap you must innovate

– Capitalist Societies encourage innovation

The Rise of ‘Capitalism’

• If this argument is right,

– The expansion of capitalism ought to increase innovation

– The most ‘capitalistic’ societies ought to have led the ‘Modern Revolution’

Prime Mover 3: Expanding Networks of Exchange

• Innovation & Collective learning depend on the variety, size and efficiency of exchange networks

• 16th century 4 world zones joined, creating:

– The largest, most dynamic networks ever to exist

• These changes kick started the two other drivers of innovation:

– Commerce

– Capitalism

CONCLUSION TO PT. 2

3 drivers of innovation that were marginal in the agrarian era have become dominant:

1. Commerce:

2. Capitalism:

3. Expanding Networks of Exchange:

1. Describing the Modern Revolution

2. Explaining the Modern Revolution

3. Explaining the “Rise of the West”

Pt. 3: The ‘Atlantic World’ in the Modern Revolution

• The Modern Revolution: a global process• But the ‘West’ changed first: Why?

All 3 drivers benefited Europe first:1. COMMERCE: European societies gained most from

new, global commercial exchanges2. CAPITALISM: European societies

more ‘capitalistic’3. GLOBALIZATION:

Europe and Atlantic region central to globalexchange networks

1) Commerce: European societies gained most from the first global markets

1. European ships dominated the first global trade routes from 1500

– Benefited from many forms of arbitrage

– E.g. transporting American silver to China

2. Vast profits increased the power and influence of merchants and of commerce

– Commerce became increasingly important to European societies

– A growing commercial/merchant class

– States became more dependent on commerce

2) Capitalism: European societies were ‘pre-adapted’ to modernity

1. New States:

– First European states from c. 500 CE

– Formed in a more commercial era

2. Because they were new, they were‘pre-adapted’to a more capitalist world:

– Governments relied more on commerce

– Merchants more prominent & powerful

3. Competitive, medium-sized states

– Desperately needed revenue but limited tax base

– C.f. China during most of its history

3) A new global Geography: The “Atlantic Region” at the center of

the 1st global exchange network

• Globalization after 1500 CE

– Europe, uniquely, found itself at the hub of

• Largest

• Most dynamic

– Exchange Networks ever

• New flows of wealth and information stimulated innovation as never before

Summary: The ‘Modern Revolution’• One more fundamental transition: the ‘Modern Revolution’• Main changes:

– Population growth accelerated– Innovation faster than ever before: new sources of energy (‘fossil fuels’)– Lifeways transformed– New ways of thinking about the world– Acceleration in the pace of change

• Explaining the Modern Revolution– Focus on explaining more rapid innovation– Three powerful drivers of innovation more powerful

• Commerce• Capitalism• Linking of different world zones collective learning goes global

• Explaining the role of ‘the West’– Pre-adaptations: The West was peculiarly ‘capitalistic’– Globalization: The linking of the Afro-Eurasian and American zones put the

West at the center of global exchanges of ideas and goods

Key Questions

Why Europe roots of Modern Era?– How did commerce expand?

– How did the world become more capitalist?

– How did the world become more global?

Chinese porcelain trade

• Early evidence of exports to India and Mediterranean: – Exports of ceramics by sea increased as Song China cut off

from northern routes

– Ceramics cheap and easy to transport by sea

– Stimulating demand in the Muslim world

• Porcelains sold in Muslim world from 9th c.

Growth in Chinese sea-borne trade from 11th century

• S. Song (1127-1276) cut off from land routes by Jurchen & Xia-Xia– Based in increasingly populous & commercial south– Turn to sea routes: trade 20% of government revenues– Chinese Indian Ocean trade booms– Particularly benefits ceramics, unsuitable for land transport– Special designs ordered by Muslim buyers

• Huge increase in trade in porcelain– 12th century merchant from Guangzhou on ships leaving harbor: “the

greater part of the cargo consists of pottery, the small pieces packed in the larger, till there is not a crevice left.” [Finlay, 152]

but the blue glaze tended to blur in the kiln

Why did innovation not spread?

1. After 1279, China united again

– Less need for revenues from commerce (government banned all foreign trade by native Chinese)

– Return to traditional tributary revenues mainly from land

– Global communications still slow

– Chinese inventions spread slowly

2. The world not yet united enough or commercial enough for an ‘industrial revolution’

Commerce encouraged Capitalism

• Increasing commerce affected

– Peasants

– Rulers

– Merchants, entrepreneurs, bankers

• i.e. societies became more capitalistic

• Remember: A ‘Capitalist’ society is one in which

1. Goods exchanged through markets (not tributes)

2. Entrepreneurs call the shots (not traditional rulers)

3. Most people are wage-earners (not peasants)

As commerce spread, peasants had to become more ‘capitalistic’

To buy goods and pay taxes, peasants had to earn wages or sell goods

on local markets.

market in Lomé, the

capital of Togo

Rulers of smaller states more commercialized & ‘capitalistic’

• Large imperial states (e.g. China), with huge populations and plenty of tax revenue from the land, did not need to support commerce

• Smaller states needed commercial revenues to survive, so …

– They supported commerce & borrowed from bankers

– Merchants became more powerful

– Early forms of capitalism thrived

• Commercial City States, e.g. Venice, or Genoa

– used commercial wealth to pay for powerful navies and armies

Venice, a purely commercial power, dominated trade between the Islamic

world and Christian EuropeThe Doge’s

(building started

c. 1340)

Venice was

ruled by

merchants: very

different from

traditional

tributary states

The Commercial Dynamism of European States

• By comparison with the great tributary empires, W. European states were

– Small and had limited revenues

– Engaged in constant warfare

• Needed commercial revenues to survive, so they tended to support trade

– With money

– And military force, where necessary

• Spanish, Portuguese, Dutch, English colonial empires

Increasing commerce led to important innovations in Europe

• Many innovations borrowed from China

• SHIPPING, COMMUNICATIONS AND WARFARE: – Improved ships (Portuguese “caravel”), compass

– Paper and printing (Gutenberg, 1453)

– Cannons that could be carried on ships

• BANKING AND FINANCE:– More efficient ways of transferring cash

– New types of joint-stock companies

• Government-supported commercial voyages by sea – Portugal, Spain, then England, Netherlands, trying to link up with

the rich trading networks of the Indian Ocean

– the first global networks of exchange

• EUROPE SUDDENLY AT THE CENTER

Columbus’ 4 voyages: 1492-1504

Magellan’s voyage: 1519-22A momentous turning point in World History

The first person to circumnavigate the globe

was probably a Malay slave and interpreter,

Panglima Awang, who was returned home

Spain’s power depended on control of American silver & trade

The Spanish Empire in 1770European navigators went looking

for a share of the biggest markets

in the world, in S.E. Asia

RESULT? GLOBAL TRADE: Spanish silver, mined by slaves

from Africa, allowed European Spain to buy goods from E. Asia

Europe after Columbus: at the centre of the first global networks!

The impact on European thought

• Huge flows of new information through Europe – Awareness of new cultures and ways of thought

– Forced them to question former ways of thinking

– And ask new questions:

• New Questions:– How could you know what was true?– Were there universal principles true in all parts of the

world?

• These questions are the start of modern science

Modern Science: Galileo

Galileo Galilei (1564-1642), argued

that knowledge can be tested by

careful observation

One of the first telescopes.

Galileo used them to show that the moon had

craters, and Jupiter had many moons

Science: Sir Isaac Newton

Sir Isaac Newton (1642-

1727).

Showed that the laws of

gravity were universal.

They worked in heaven

and on earth.

WHAT CHANGED AFTER 1700?

Just about everything!

Next Lecture: the take-off into modernity

Summary: On the eve of the ‘Industrial Revolution’

• Two great Malthusian cycles before 1700 CE:– The ‘post-classical’ cycle: 600-1450– The ‘early modern’ cycle: 1450-1700

• What changed?– Commerce spread– Globalization: networks of exchange now global– Capitalism: affecting societies everywhere– Europe:

• Now at the centre of global networks of exchange• New ideas beginning to take hold

• What didn’t change?– In 1700 traditional empires were still dominant– Most people still lived as traditional peasants– The ‘Modern Revolution’ had not yet started
