Nonzero

IDEA 1
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
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
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 1
Evolution shaped human morality
Wright argues that evolutionary psychology can explain much of human behaviour, including love, friendship, guilt and morality. He believes our moral feelings were shaped by natural selection. He stresses that explaining a feeling is not the same as excusing it.
IDEA 2
Darwin's life illustrates the ideas
Wright uses Charles Darwin's own life, including his marriage and career, as a case study. He shows how evolutionary ideas can explain Darwin's choices. Wright treats Darwin as a living example of how ideas about human nature can illuminate a person's life.
IDEA 3
Mate choice has evolved patterns
Wright discusses evolutionary theories about how men and women choose partners. He presents these as broad tendencies studied by scientists. He stresses that these are patterns across large groups, not rules that fit every person.

IDEA 1
Evolution did not favour truth
Wright argues that natural selection shaped our minds to help our genes spread, not to see reality accurately or to make us lastingly happy. Many of our feelings and beliefs, he suggests, mislead us.
IDEA 2
Buddhism diagnosed the problem
Wright argues that ancient Buddhist teachings identified the same problem that evolutionary psychology describes. Both see the mind as prone to illusions that cause suffering. In his account, the two traditions describe the same trouble from different directions.
IDEA 3
Feelings were built to push us
Wright explains that pleasures fade quickly because evolution designed them to keep us striving. This explains why satisfaction never lasts. Wright says the mind is built to chase the next reward, not to rest in contentment.
