A Canticle for Leibowitz: A must-read for any true SF fan

science fiction book reviews A Canticle for LeibowitzA Canticle for Leibowitz by Walter M. Miller Jr

It’s the Dark Ages again. A 20th century nuclear war spawned a “Flame Deluge” which destroyed human civilization’s infrastructure and technology, killed most of the people, and created genetic mutations in many of the rest. Then there was a backlash against the educated people of the world who were seen as the creators of both the ideas that started the war, and the weapons that were used to fight it. They were persecuted and killed and all knowledge was burned up. After this “Simplification,” people took pride in being illiterate and the only institution that seemed to come through intact was the Roman Catholic Church, just as it did during humanity’s first Dark Ages.

Walter M. Miller Jr’s A Canticle for Leibowitz is divided into three parts, which were originally published as three separate stories. In the first story, “Fiat Homo,” which takes place 600 years after The Simplification, we find a cloister of monks who are applying to New Rome to have their martyred patron, an ex-electrical engineer named Isaac Edward Leibowitz, sainted. Leibowitz’s monks have been collecting, preserving, and copying fragments of the Earth’s previous civilization. As keepers of pre-Deluge history, they attempt to piece together knowledge and history, without knowing for certain what they’re looking at. One day, while maintaining a vigil of silence in the desert around the abbey, Brother Francis stumbles upon the entrance to Leibowitz’s fallout shelter containing precious relics, such as a circuitry blueprint and a deli shopping list. These relics cause quite a stir in the abbey.

“Fiat Lux” begins 600 years later. Genetic mutations caused by the fallout are still affecting mammalian DNA, and the monks of St. Leibowitz occasionally wonder whether there really ever was an advanced civilization on Earth, but progress is gradually being made. This is especially true in the abbey of St. Leibowitz where the monks are safe from the tribal wars that are common in surrounding Texarkana. Their studies of the fragments they’ve been collecting have prepared them to ignite a new renaissance.

Another 600 years pass. In “Fiat Voluntas Tua,” humans, though still affected by “genetic festering,” have reached the pinnacle of civilization and culture, progressing beyond what had been experienced before the nuclear war in the 20th century. But there’s been a cold war going on for 50 years between the two world superpowers and they both have nuclear weapons. At the abbey of St. Leibowitz, the monks wonder if humans are destined to repeat the cycle and, as keepers of the world’s knowledge, what is the abbey’s responsibility to humankind?

Are we doomed to do it again and again and again? Have we no choice but to play the Phoenix in an unending sequence of rise and fall? …. Are we doomed to it, Lord, chained to the pendulum of our own mad clockwork, helpless to halt its swing? This time, it will swing us clean to oblivion… Back then, in the Saint Leibowitz’ time, maybe they didn’t know what would happen… They had not yet seen a billion corpses. They had not seen the still-born, the monstrous, the dehumanized, the blind. They had not yet seen the madness and the murder and the blotting out of reason. Then they did it, and then they saw it… Only a race of madmen could do it again.

Obviously, the main theme of A Canticle for Leibowitz is the repetitive cycle of human history and the role of our advancing knowledge and technology in our own destruction. This provides the reader with plenty to think on, but Miller also addresses issues that the Roman Catholic Church has tackled during its history, such as its role in state politics and its insistence that euthanasia is a sin. While the novel is meant to be a serious consideration of these ideas, and while its predictions and warnings are frightening, A Canticle for Leibowitz still manages to be amusing and agreeably quirky all the way through. Though there’s a powerful and unforgettable message here, it is the irreverent, eccentric humor that makes it so enjoyable to read.

A Canticle for Leibowitz is a classic piece of post-apocalyptic science fiction that had mass cross-genre appeal when it was published in 1960, won the Hugo award in 1961, and has never been out of print. Thus, it’s a must-read for any true SF fan. I recently tried the audio version which was just released by Blackstone Audio and narrated by Tom Weiner. Audio readers, even if you’ve read A Canticle for Leibowitz before, you won’t want to miss Blackstone Audio’s first-rate production of this imaginative, chilling, and humorous novel.
