- IDEA 1 OF 8
History has a direction
Wright argues that human history, and even biological evolution, show a clear direction towards greater cooperation and complexity.
He believes this trend arises from the logic of non-zero-sum games. He sees this as a long pattern, not a guarantee.
- IDEA 2 OF 8
Cooperation can benefit everyone
Wright explains the difference between zero-sum games, where one side's gain is the other's loss, and non-zero-sum games, where both can win.
He argues that much of human life involves the second kind.
- IDEA 3 OF 8
Groups grew larger over time
Wright traces how human societies grew from small bands to chiefdoms, states and empires.
Each step, he argues, allowed more people to cooperate for mutual benefit. Bigger groups meant more trade, shared rules and shared plans.
- IDEA 4 OF 8
Technology widened cooperation
Wright argues that inventions such as writing, money and printing made it easier for people to share information and trade.
These tools expanded the scope of non-zero-sum relations. Each tool lowered the cost of working together.
- IDEA 5 OF 8
Trade links strangers
Wright describes how trade between distant groups created shared interests.
People who depend on each other have reasons to get along. A seller and a buyer both gain when an exchange goes well, so each wants the other to prosper.
- IDEA 6 OF 8
Conflict also spreads cooperation
Wright argues that even war has pushed societies to organise in larger units.
Competition between groups encouraged cooperation within them. In his view, groups that joined forces could defend themselves better, which pushed others to do the same.
- IDEA 7 OF 8
Evolution also moves forward
Wright suggests that biological evolution shows a similar direction towards complexity and intelligence.
He sees this as part of a larger pattern. He is careful to say this is an interpretation, not a proven law of nature.
- IDEA 8 OF 8
Morality may expand
Wright argues that as cooperation widens, people's moral concern may grow to include more of humanity.
He suggests this could give history a kind of meaning. He presents this as a hopeful possibility, not a promise.
