Seife has a number of biases that the reader should be aware of. First, his perspective on Aristotle holds that Aristotelian physics and even metaphysics was a barrier to scientific progress because it was inevitably hostile to the idea of nothingness. There are many who think that Aristotelian physics and metaphysics were barriers to scientific progress, but next to none who think this due to Aristotle's attitude towards nothingness. Second, and relatedly, Seife's conception of the relationship between zero and theology is highly stylized in part as a result of his conception of the role of Aristotle within Catholic theology.
