One subject will appear in section 1, juxtaposed with a seemingly unrelated subject in section 2 (for the shorter essays in this book, replace "section" with "paragraph"), and sometimes a third or a fourth subject will appear, and we are to trust Goldbarth will connect these topics into a satisfactory thematic whole by the end; this is typical of the sort essay form that appears in literary magazines that aren't the ones you can find in a Barnes & Noble but nevertheless command some level of cachet among writers (if not among lay readers). Whether you find the essays in this book satisfying or not will depend on how impressed you are with Goldbarth's whimsical use of English paired with the usual high-brow elision of explanation and transition - this is learned writing for learned readers, can't make things too easy for us - and whether you consider modern concepts like "scientific truth" or "time" as malleable as Albert seems to. I'm reminded of Bernard Nightingale of Tom Stoppard's Arcadia who prefers the 55 crystal spheres of Aristotle's cosmos.
The two large essays that make up the bulk of this book are pretty good. Skip the rest and just read those.
Goodreads doesn't allow fractional reviews, so I can't give this book the 2.5 stars I'd like to: perfect mediocrity.
