Morris begins in the first chapter by setting the foundation for the rest of the book and in this first chapter he talks about the difference between living in a small group and what happens when you start living in a very big group (in a city so to speak!). He then also points out that living in a city is like putting animal into cages or zoos: they start acting very weird!
The two next chapters are about how living in a city affects our struggle for status and our expression of our unique sexualities. The chapter after that shows roots of prejudice and why the holocaust actually happened.
The next chapter then will tell you the roots of fetishism and why some people just have to express their sexualities in certain circumstances.
Then the chapter after that gives you a whole new perspective on why some housewives are willing to cheat (the answer will surprise you in a funny way!). And the last chapter gives us some insight on playfulness.
I think this book was a great book on learning why the city-life can be so stressful and what to do about it: understanding one's urges and what to do so you can satisfy them and decrease the ongoing stimulus struggle.
