Abstract: | Darwin proclaimed his own work revolutionary. His revolution, however, is still in progress, and the changes that are going on are reflected in the contemporary historical and philosophical literature, including that written by scientists. The changes have taken place at different levels, and have tended to occur at the more superficial ones. The new ontology that arose as a consequence of the realization that species are individuals at once provides an analytical tool for explaining what has been happening and an example of the kind of changes that seem in order. It provides a clear distinction between the roles of history and of laws of nature. Pre-Darwinian evolution was superficial in the sense that it treated change as either as something pre-ordained or else due to timeless laws of nature, rather than historical contingency. Darwinism puts the ontological emphasis upon concrete, particular things (individuals) and therefore delegitimizes both essentialistic and teleological ways of thinking. However, traditional ways of thinking have persisted, if not explicitly, then often as assumptions and procedures that are merely implicit or even unconscious. As a result, anti-evolutionary attitudes continue to influence the practice of evolutionary biology as well as the study of its history and philosophy. |
