February 16th Topic- The Import of Evolution in Philosophy

The Import of Darwinism in Philosophy

Darwin's conceptual scheme for explaining the origin and evolution of species as being a consequence of natural selection has become the conceptual thread that ties together essentially all of modern biology.  More remarkably, what we may loosely call Darwinism has impacted nearly every field and perennial question in philosophy.

At least five reasons readily come to mind why Darwin's ideas have had such broad impact.

1)  By providing an alternative to intelligent design as the explanation of the origin of all living and extinct species, including Homo sapiens, Darwinian evolution undermines one of the most compelling arguments for the role of a supernatural creator in the natural world and in human affairs.  This alternative explanation reopens a great many philosophical questions in which Western thought had previously presumed a major role for the Creator.  It thus impacts metaphysics, ontology, and ethics.

2)  By invoking gradual change as the mechanism of the development of all the amazing variations of form and behavior seen among living things, Darwinism calls into question many of the sharp distinctions made historically by philosophers and pre-Darwinian scientists.  Epistemology and volition in an evolved creature cannot be entirely separate from biology.  Neither can ethics, social organization (including concepts of governance and justice), or esthetics, since each of these could at least potentially be subject to natural selection.  

3)  By invoking chance as the raw material on which natural selection can work, Darwinism begs the question as to how much of our nature, history, and culture are, even more than we previously suspected, the result of chance rather than of destiny or physical or historical laws.  Thus Darwinism further impacts virtually all the fields mentioned above.

4)  Since Darwinism in itself invokes no values, and requires of "fitness" only that it be a measure of the ability of an individual to have fertile offspring in its current environment, the structure of the theory gives considerable inspiration to all those who contemplate relativism in many different fields.  

5)  Since evolution through natural selection applies not only to biological populations, but to any system in which entities are capable of reproduction with random alterations and variable reproductive success, Darwin's ideas also have at least some bearing on cultural products and beliefs, and perhaps also nonliving physical forms, from tiny crystals to the nature of the multiverse.

Obviously, in our cafe, we have no hope of being exhaustive, balanced, or scholarly in our evaluation of the impact of Darwinism.  Instead, we propose to conduct a parlor game:  Any player may nominate a philosophical field or question as one upon which Darwinism has had, or should have, no significant bearing.  To that nomination, the cafe will respond with either assent or counter-examples, and probably both!  

In honor of Darwin's February birthday, we invite you to the party and encourage you to bring a nomination to share.
