"During the past fifteen years, Robert Stalnaker has published an important series of papers on issues concerning conditionals, possible worlds, and belief. In Inquiry, he brings together themes from these papers and attempts to weave them together into a single line of thought. The result is a book which ... is densely argued and full of interest. One of its admirable features is its style: Stalnaker manages to write lucidly and economically on difficult topics without assuming undue familiarity with the literature and its jargon."
