The title refers to a paradox famously stated by physicist Enrico Fermi. This is a revision of the author's 2002 book (CH, Mar'03, 40-3987) in which he proposed 50 solutions to the paradox; here he lists 75. They fall into three general categories: "They Are (or Were) Here," "They Exist, But We Have Yet to See or Hear from Them," and "They Don't Exist." There are 397 notes and 21 pages of references. The arguments are engaging, clearly reasoned, and accessible to general readers. There are many wonderful quotes ("Chance is perhaps God's pseudonym when he does not want to sign"--Anatole France) and anecdotes (a giant African snail pulling a DVD could exceed all current "last mile" communications technologies in efficiency). As with all excellent books on extraterrestrial intelligence, readers gain greater insight into what being human means ("We're searching for ourselves"). Physicist Webb concludes that humans may well be the only civilization in the galaxy, a possibility that Astronomer Royal Martin Rees describes in the foreword as entitling humans to be less "cosmically modest." This is one of the best books ever written on the subject of extraterrestrial intelligence. Summing Up: Highly recommended. All readership levels. --Timothy Barker, Wheaton College (MA)
