"A psychologist colleague, on reading a draft of this essay, asked if The Selfish Gene is considered required reading in any philosophy graduate program. Certainly specialists in the philosophy of science or philosophy of biology would be expected to have read it, but what about students of epistemology or philosophy of mind or language? We philosophers are a somewhat conservative lot, loath to grant that anybody but a professional philosopher could write something worthy of entry into the canon. If you put The Selfish Gene on the required reading list, just which ‘classic’ would you bump from the list to make room for it? I have seen enough philosophy students enthusiastically tell me how they were transformed by reading the book to judge that it pulls its weight and then some, so yes, I put Dawkins’ book alongside classics by such non-philosophers as Turing and Kuhn as essential thinking tools for any student of philosophy. In addition to everything else they will learn from it, they will discover that it is actually possible to write arguments that are both rigorous and a joy to read. That discovery, if enough philosophers took it to heart, could transform our discipline."
