NOTE: Ernst Haeckel was a key figure in social darwinism and leading proponent of scientific racism. This book is not about these topics and the stocking of it is in no way an endorsement of these thoroughly disproven, pseudoscientific views.
Thinker's Library edition. Covering cosmology and the soul. There is a tape stain of some kind on the first page. Some slight tears to the edges of the dust jacket, as well as a mark. Otherwise in fine condition.
