Hierarchy, network, nature
Our 21st century predicament
Hierarchy, network, nature
The axes of history
Hierarchy
Networks
Environment
Plus the Fourth Axis: Time
The three axes
Nature The material
constraints over which we have no control
Hierarchies Ver5cal
organiza5ons with command and control
Spontaneously self-‐organizing horizontal structures
Networks
Nature
1. Physics 2. Geography 3. Geology 4. Climate 5. Disease 6. Evolu5on 7. Fer5lity 8. Bell curve
The environment is not wholly a given; it can be
shaped by, as well as shape, humanity
Networks
1. Knowledge / Memes 2. Migra5on 3. Miscegena5on 4. Informa5on Technology 5. Markets 6. Clubs 7. Ci5es 8. Cults 9. Movements 10. Crazes
Networks are spontaneously self-‐organizing; they are the main source of innova?on, but they are quite fragile
Hierarchies
1. Clans 2. Tribes 3. Castes 4. Classes 5. Armies 6. States 7. Churches 8. Bureaucracies 9. Corpora5ons 10. Par5es 11. Universi5es 12. Empires
Hierarchies exist primarily because of the economies of
scale and scope in security, but also to extract rents from
networks
History explained
• Environmental changes oben incen5vize innova5on by networks
• Networks tend to disrupt established hierarchies
• Hierarchies seek to exploit the benefits of networks

This is not some kind of determinis?c sequence
Example 1: From the Black Death …
The “Black Death” (Yersinia pes5s bacterium carried by rat fleas) killed 30-‐60% of Europe’s popula5on: peak years 1348-‐50.
… to rising real wages in western Europe
Survivors’ real wages rose by a factor of around 3 in the following century
But already medieval Europe was more networked
The Guildhall, home of the City of London Corpora5on (C12th)
… than hierarchical imperial China
Chinese imperial civil service examina5on, reign of Emperor Renzong (Song dynasty, 1010-‐1063)
Example 2: From the print revolu5on …
Johannes Gutenberg (c. 1440-‐50) “invents” prin5ng press in Strasbourg
… to the Reforma5on
Joachim Vadian, humanist polymath who brought the Reforma5on to St. Gallen
The print revolu5on …
Volume of books increased a hundredfold between 1495 and 1635; the price of a book fell 99%

Example 3: From wars of religion …
St. Bartholomew’s Day massacre of Huguenots, Paris, 1572
… to hierarchical order
The Peace of Westphalia (Treaty of Munster, 1648)
Western empires: Networks …
Major telegraph lines, submarine and overland, 1902
… plus hierarchies
Delhi Durbar, 1903
Example 4: Triumph of the hierarchies
Alfred Sloan’s “Organiza5on Study” for GM, 1921.
Empire-‐states: Great Helmsmen …
… and mass mobiliza5on of youth
The planner’s dream: The economy as model
