What is the author's style in The Everlasting Man by G. K. Chesterton?

Chesterton attempts to strike a balance between the sincerity of his belief in the book's primary theses and his awareness of his lack of his credentials: Chesterton is a renowned and respected writer, but he is not trained in philosophy, theology, history, or anthropology, subjects all crucial to the study contained in this book. His strategy for dealing with this lack of education is modesty; he tries not to contradict the facts ascertained by the experts in these fields, but rather the spirit in which they interpret them.
