 There is some textual support for understanding the parts of Hobbes’ system as either deductively or reductively linked together since he did at times talk of the parts of philosophy as beginning in first philosophy and leading from one to another. For example, he asserted in De Corpore VI.6 that by beginning at first principles, one will move from first philosophy to geometry, and from geometry to physics. He continued by claiming that “after physics we come to morals” and, indeed, Hobbes claims that moral philosophy must be studied after physics because the passions have “their causes in sense-experience and imagination” (CSL 299; OL I.64).
