 A third view has more recently been offered that seeks to carve a middle path between the unified and disunified interpretations. We can call this view the mixed-mathematics view (for example, Adams 2016, 2017; Biener 2016). This understanding of Hobbes’ system agrees with the worry raised above for the unified account that ‘higher’ levels, such as geometry, do not contain the concepts used in ‘lower’ level explanations. For example, although geometrical principles are used in Hobbes’ optical explanations those geometrical principles do not contain concepts such as ‘light’ or ‘color’. Some evidence for this lack of containment claim can be found on the well-known “Table of the Several Subjects of Science” in Leviathan IX. The “sciences” on this table are listed on the right-most section and their subjects are to the immediate left. The subject of the science of optics, for example, is all of the “consequences from vision”, and these stem from “Physics or consequences from qualities”. The science of geometry, however, has as its subject the “consequences from quantity, and motion determined… by figure” and these stem not from physics but from “consequences from the accidents common to all bodies natural; which are quantity and motion”.
