Six scientists and philosophers interviewed in this book, only Henri Atlan was unknown to me; so I discovered with great interest. I have not been disappointed. Of course, the book is not intended to answer the question, but it opens up lines of thought that are very interesting. I will not hide my enthusiasm about Albert Jacquard, because it is an exceptional man whose views are often relevant. The development of diverse opinions is constructive confrontation, especially here. In addition the book designed as interviews is excellent, very pleasant to read. A very good book, fail.
