Sahotra Sarkar, a philosophy professor and integrative biologist at the University of Texas at Austin also criticised Fuller's book for presenting an "analysis of the intellectual disputes over contemporary ID creationism is almost vacuous". Sarkar further states that the book has an idiosyncratic interpretation of the history of philosophy, including of Kant, and of logical positivism; having a limited grasp of the history of science, including making claims about Newton, Cuvier, Agassiz, Lamarck, Mendel, Pearson and Galton that are not supported by their writings; failure to engage the "debate over naturalism that ID creationism has generated" with "remarks on supernaturalism [that show him to be equally non-cognizant of the work of ... Philip Johnson"; and other scientific errors.
