The winding road is the result of happy-go-lucky heedlessness, of looseness, lack of concentration and animality.
The straight road is a reaction, an action, a positive deed, the result of self-mastery. It is sane and noble.
A city is a centre of intense life and effort.
A heedless people, or society, or town, in which effort is relaxed and is not concentrated, quickly becomes dissipated, overcome and absorbed by a nation or a society that goes to work in a positive way and controls itself.
It is in this way that cities sink to nothing and that ruling classes are overthrown.
