This is the first of a pair of volumes by Jonathan Hodge, collecting all his most innovative, revisionist and influential papers on Charles Darwin and on the longer run of theories about origins and species from ancient times to the present. The focus in this volume is on the diversity of theories among such pre-Darwinian authors as Lamarck and Whewell, and on developments in the theory of natural selection since Darwin. Plato's Timaeus, the Biblical Genesis and any current textbook of evolutionary biology are all, it may well seem, on this same enduring topic: origins and species. However, even among classical authors, there were fundamental disagreements: the ontology and cosmogony of the Greek atomists were deeply opposed to Plato's; and, in the millennia since, the ontological and cosmogonical contexts for theories about origins and species have never settled into any unifying consensus. While the structure of Darwinian theory may be today broadly what it was in Darwin's own argumentation, controversy continues over the old issues about order, chance, necessity and purpose in the living world and the wider universe as a whole. The historical and philosophical papers collected in this volume, and in the companion volume devoted to Darwin's theorising, seek to clarify the major continuities and discontinuities in the long run of thinking about origins and species.

Several years ago Lord Rosebery founded, in the University of Edinburgh, a lectureship on “The Philosophy of Natural History,” and I was invited by the Senatus to deliver the lectures. This invitation I accepted, and subsequently constituted the material of my lectures the foundation of another course, which was given in the Royal Institution, under the title “Before and after Darwin.” Here the course extended over three years—namely from 1888 to 1890. The lectures for 1888 were devoted to the history of biology from the earliest recorded times till the publication of the “Origin of Species” in 1859; the lectures for 1889 dealt with the theory of organic evolution up to the date of Mr. Darwin’s death, in 1882; while those of the third year discussed the further developments of this theory from that date till the close of the course in 1890.
