“The way people spoke reflected the way they thought and the way they acted.
If they talked in circles they walked in circles.
If they talked in legalese they legislated their way round problems instead of cutting through them.
If they qualified everything they said, everything they did would be qualified.”

The way you talk reflects the way you think. And the way you act is an insight into the way you talk and think.
So, the components that add up to the way we approach situations (such as our formal education, the people we surround ourselves with, whether we appeal to logic and rationality or emotion) are borne out in how we think, act and talk.
