"Armchair Cogitations" continues in the apparently semi-autobiographical vein of "Pathways", Herbert Kaufman's previous book. The section "Air Force Vignettes", especially, provides a glimpse into a world that, in some ways, no longer exists. However, just when you think that a piece is going to be primarily nostalgic in nature, an event or conversation between characters shifts the emphasis. Often we understand then that the relationships between humans broadly follow along certain well-worn paths; what may appear as our own original, highly personal drama is part of an existence common to all of us. Perhaps the reader's age will, in part, determine the extent to which he or she may empathize with some of the book's characters and situations, but there is much that all will recognize.
