What is the author's tone in The Ethics of Ambiguity; by Simone De Beauvoir?

The Ethics of Ambiguity is a work of moral philosophy and as such it may often come off to the reader as dry and obscure. Beauvoir uses many complex terms and phrases that will initially seem incomprehensible to the reader. When she speaks, for instance, of human existence as an existence that tries to move beyond its existence, the reader may understandably be confused. The book also focuses on the contributions of other philosophers, which are outlined without any context in terms of explaining who they are; thus the reader unfamiliar with these figures will not be able to appreciate these parts of the book.
