What is the author's style in Intellectuals by Paul Johnson?

Intellectuals is written in the third person point of view with the narrator being the author, Paul Johnson. This approach allows Johnson to provide the background information that the reader needs to understand the points that the author is making. This is the only approach that could be used in a book of this nature. It allows the author the greatest amount of flexibility in the amount and kinds of information that the author wants to present and this is the kind of book where the reader requires background information.
