A rehash of Enlightenment views of religion, but, as the reviewer points out, in Victorian language and with arguments better made by Lord Russell. Russell was at least a competent philosopher if also personally a cad.
Russell was that, fer shure.
Early in his career he was a racist, advocating birth control for non-whites, and was pro-eugenics. He lived long enough to begin the crusade against the Jewish state after the 1967 war. For all his celebrated nonconformity, he seems to have had many of the prejudices and behaviors of his class.
