What is the author's style in Orthodoxy by G. K. Chesterton?

Orthodoxy is a non-fiction book divided into nine chapters, each with its own distinct theme. Aside from the first chapter, which is a brief introduction to the book, there is not an obvious reason for the order of the book. Rather, Chesterton seems to be concerned with addressing many of the reasons why modern liberals take issue with Christianity and takes on these issues generally a chapter at a time.
