 There has been debate among scholars of Hobbes’ thought about the relationship of the different parts of his philosophy to one another. Much of the focus has been upon the methodological statements in Part I of De Corpore, and scholars have traditionally divided over whether Hobbes understood philosophy as unified or disunified. However, more recent scholarship has drawn attention to Hobbes’ practice of explanation, such as the explanations found in De Corpore Part IV, and has argued that aspects of both the unified and disunified views track Hobbes’ discussions and practice while those views on their own miss that Hobbes explicitly borrowed principles from mathematics to use in natural philosophy (and provided citations to show this activity). This section will discuss these three approaches to understanding how the parts of Hobbes’ system fit with one another and then provide an example of an explanation in Hobbes’ natural philosophy from De Corpore XXV.
