James P. Hogan has a mixed record in the world of "hard" science fiction, with some good books and some not so good. His latest novel, "Cradle of Saturn" (COS), goes well beyond the "not so good" into the "terrible". Ideally, good science fiction results from the combination of good fiction plus at least reasonably plausible science. Unfortunately COS fails on both counts. The writing is turgid and uninteresting, and the "science" is pathetically bad.
In recent years Hogan seems to have fixated on the idea that a conspiracy of scientists is attempting to conceal the Truth about a variety of topics, including AIDS, the stratospheric ozone layer, dinosaurs, evolution, and so forth. Most of the reasoning he uses to support these claims is neither original nor credible. As someone who has some familiarity with atmospheric chemistry, I can say with confidence that most of his allegations about stratospheric ozone are worthless.
Yet in COS, Hogan carries his anti-scientific revisionist nonsense far, far beyond most of his earlier writings. The central theme of this book based on the work of Velikovsky, a crackpot whose ideas about the history and dynamics of the solar system were unsupportable when first published in the early 1950s, and have only become more so in the past half century. To justify his use of Velikovskian ideas, Hogan has to bend, break, or ignore most of modern geology and physics.
Some might argue that the science doesn't matter, as long as the literary side of COS is well done. Unfortunately, it's not. Hogan's characters are cardboard cutouts, with no depth or personality. His prose is uninteresting, and the story frequently is pushed aside to make room for thinly-veiled rants relating to Hogan's bizarre anti-scientific obsessions. It IS possible for a persevering reader to make his or her way through to the end of this book, but the question is -- why would one want to? There are far more worthwhile books out there than could possibly be read in anyone's lifetime; plowing your way through "Cradle of Saturn" will only prevent you from reading something else that would probably be infinitely better.
If you really want to read something interesting by Hogan, I'd recommend "Inherit the Stars" and "The Proteus Operation" over "Cradle of Saturn" any day.
