Space prohibits the detailed comment so enterprising, formidable and rather dismaying a work such as this deserves. In form, simple (seven distinguished philosophers are interrogated by a host of distinguished colleagues); in content, complex (cross-references, specialized language, seminar problems). The seven and their stripes are: Paul Weiss, head mandarin of the Review of Metaphysics, a totalist philosopher responsible for the book; Martin Buber, engaged in his familiar dialogical ""truth,"" Hasidic encounters; Paul Tillich, the Protestant theologian, who harks back to teleological interests, to structures of faith; John Wild, long a classical realism drum-beater, who now incorporates phenomenology, existential authenticity, Husserlian Lebenswelt; Jean Wahl of the Sorbonne accents freedom, metaphysics, Bergsonism; the last two, Brand Blanshard, of extensional logic and internal relations, and Charles Hartshorne, of Whiteheadian ""process"" thinking and ""quantized events,"" being more scientifically oriented stand apart from the others. A number of questions are of the sort which have made philosophy a conundrum to the common men; e.g. ""Is it true... nothing is what it is, but always some other thing?"" Aside from self-indulgent scholasticism, there's another snag. We have the question and the answer but no follow-up, so that he who answers has the last word. Can anything very conclusive come from such a press-conference presentation? Buber and Blanshard are the attention-winners. This is the first in a projected series. A professional windfall, in a sense.
