Victorian biologist and social philospher Spencer has largely been neglected in the literature, and Francis remedies that here. He covers well the many problems in Spencer's life: e.g., his conflicts with his overbearing and troubled father, his inability to form and consummate loving relationships with the women in his life (notably, novelist George Eliot), and his battles with depression, melancholia, insomnia, and hypochondria. Although Francis prefers to call this an "intellectual biography"and it certainly is that, because much of it deals with the ideas and controversy surrounding the nature of evolutionwhat sets it apart is its insight into Spencer's inner conflicts and aspects as well. Ours is often referred to as the Age of Anxiety, and in this sense, the picture of the troubled person who emerges here indicates why the author places him squarely in 'modern life.' Recommended for most collections.
