This volume offers 16 essays, most of which originated in papers presented in late September of 2001 at a conference in Jena, Carnap‟s intellectual birthplace. It was in Jena, where Carnap attended university and received his Ph.D. in 1921, that he took his first steps towards philosophical maturity. While the title of the collection suggests a single interpretative theme of the importance of Carnap‟s Jena origins, most of the essays have little to say about this period of Carnap‟s intellectual development. Instead, the aim of the editors is to „bring home‟ or emphasize how important Carnap‟s philosophy was and how important it still should be. Thus, in the first essay that acts as an introduction, Gottfried Gabriel insists “that Carnap is a much subtler and more sophisticated philosopher, on many more fronts, than was generally suspected even a few years ago” (3). The danger of such an approach is that it could blind an interpreter to the weaknesses of her subject. I am glad to say that none of these essays errs in this direction, although there is a decidedly pro-Carnap feel to many essays. In the end, we find 16 high-quality essays that convincingly make the case both that Carnap is a philosopher of first-rate importance and that Carnap scholarship has reached a new stage of rigor and thoroughness.
