Although historians have carefully examined exactly what role the analogy between artificial and natural selection might have played in Charles Darwin's discovery of natural selection, philosophers have not devoted much attention to the way Darwin employed the analogy to justify his theory. I suggest that philosophers tend to belittle the role that analogies play in the justification of scientific theories because they don't understand the special nature of analogical inference. I present a novel account of analogical argument developed by Julian (...) Weitzenfeld and then use it to carry out an in-depth analysis of Darwin's argument from artificial selection. (shrink)

I want to explore four different exercises of interpretation: (1) the interpretation of texts (or hermeneutics), (2) the interpretation of people (otherwise known as "attribution" psychology, or cognitive or intentional psychology), (3) the interpretation of other artifacts (which I shall call artifact hermeneutics), (4) the interpretation of organism design in evolutionary biology--the controversial interpretive activity known as adaptationism.

There are several interpretations of the argument structure of Darwin's Origin of Species, representing Covering-Law, Inference-to-the-Best-Explanation, and (more recently) Semantic models. I argue that while all three types of interpretation enjoy some textual support, none succeeds in capturing the overall strategy of the Origin, consistent with Darwin's claim that it is 'one long argument'. I provide detailed criticisms of all three current models, and then offer an alternative interpretation based on the view that there are three main argument strategies in (...) the Origin, all supporting the 'causal efficacy' of Darwin's theory. This interpretation provides both a more unified treatment of the text, and some important implications concerning the relation between general philosophical models of scientific theory support and specific historical cases.
