Orr considers "scientism, the view that all truths are ultimately scientific" to be naive, hubristic and just plain wrong and is generally critical of what he sees as unwarranted attempts to generalise or draw philosophical conclusions from scientific facts. He laments the popular trend whereby "some pet theory gets elevated to its rightful place as 'the' way to think about evolution. But this longing to dress up biology in unusual new perspectives has, so far, yielded more book deals than results".
