Being and having;

"Part of Marcel's 'metaphysical diary' and particularly valuable in showing how the major distinctions within which his thought has been moving germinated and developed. It is, I think, the most important single source of understanding Marcel's own viewpoint...Not the least of this book's advantages is the fact that it includes many references to other thinkers who have influenced Marcel. In short, it affords an unusual and first-hand disclosure of a thinker's own self-understanding...his thought, to my mind is deeply seminal and evocative, full of fresh statement and surprising insight, while never assertive or 'dogmatic'."
