What is the author's style in Prisons We Choose to Live Inside by Doris Lessing?

The book is presented to the reader entirely from the perspective of its author, Doris Lessing, who offers her thoughts and ideas based on experience and research. Directly addressing the reader in first person, she never wavers from this personal interpretation of her topic to consider other viewpoints or to entertain opposing arguments from secondary sources. Quotes she uses, either from individuals of her acquaintance or from published writings, are selected to bolster her own arguments.
