The topic of Agnosticism consumes a relatively minor part of this book. It is interesting to read Huxley's exposition on Darwin's theory of evolution and how he makes the case for why it is more plausible than any other theory. While some of what he says would require modification in light of modern evolutionary thought, most of his arguments (using data from anthropology, archaeology, biology, embryology, genetics, geology, etc.) are still valid. Other essays include discussions on epistemology especially with regard to supernaturalism and claims of miracles. Only in the last several pages does Huxley elaborate on the origin and meaning of Agnosticism. In fact, he seems almost reluctant to descend into the discussion. He indulges the reader nevertheless and does a stupendous job of stating the case. A pleasant read on a rainy day.
