"I find the work extremely original and philosophically quite sound. Lewens's work successfully removes a lot of the irrelevant issues that contrast material theories of evolution by natural selection with notions of human design."
-- Richard Lewontin, Alexander Agassiz Research Professor, Harvard University

In Organisms and Artifacts, Tim Lewens investigates the analogical use of the language of design in evolutionary biology. Uniquely among the natural sciences, biology uses descriptive and explanatory terms more suited to artifacts than organisms. When biologists discuss, for example, the purpose of the panda's thumb and look for functional explanations for organic traits, they borrow from a vocabulary of intelligent design that Darwin's findings could have made irrelevant over a hundred years ago. Lewens argues that examining the analogy between the processes of evolution and the processes by which artifacts are created- looking at organisms as analogical artifacts-sheds light on explanations of the form of both organic and inorganic objects. He argues further that understanding the analogy is important for what it can tell us not only about biology but about technology and philosophy.
