- IDEA 1 OF 8
The mind processes information
Pinker argues that the mind is a system of organs of computation, processing information to solve problems.
This computational view, in his account, explains much of how we think. In his view, the mind works like a machine made of living tissue.

Evolution designed the mind
Pinker argues that the mind was shaped by natural selection to solve problems our ancestors faced, such as finding food and choosing mates.
This approach is called evolutionary psychology. Our modern world is very new compared with that long history.

The mind has many parts
Pinker suggests that the mind is made of specialised systems, each suited to different tasks.
Vision, language and social reasoning, for example, rely on different mental tools. He compares it to a toolbox rather than a single all-purpose tool.

Seeing is complex work
Pinker explains that vision involves the brain working out the shape and position of objects from flat images on the eye.
It is far harder than it seems. The brain solves this so fast that we never notice the effort.
- IDEA 5 OF 8
We have intuitive theories
Pinker argues that people are born with intuitive ideas about physics, living things and other minds.
These help us understand the world quickly. Young children already seem to expect that objects fall when dropped.
- IDEA 6 OF 8
Emotions serve purposes
Pinker argues that emotions such as fear, love and anger evolved because they helped our ancestors survive and reproduce.
They guide behaviour. Seen this way, a feeling is a built-in response that once solved a real problem.
- IDEA 7 OF 8
Families involve conflict and love
Pinker explores relationships within families and between friends through an evolutionary lens.
Shared genes and interests shape how people treat each other. Parents and children, for example, share many genes but not always the same interests.
- IDEA 8 OF 8
Arts may be by-products
Pinker suggests that some activities, such as music, may be by-products of abilities evolved for other purposes.
This idea has been widely debated. They may be pleasant side effects of minds built for other tasks.
