This vintage book contains Asa Gray's 1889 collection of essays on the subject of Darwinism. The articles champion the theory of evolution from a botanical standpoint, but also seek to reconcile Darwin's theory with religion, which Gray did by making a case for theistic evolution - a marriage of theology and the theory of evolution. This fascinating volume is highly recommended for those with an interest in the in the work of Charles Darwin, and it would make for a great addition to collections of allied literature.
