Science, the Singular, and the Question of Theology explores the role that the singular plays in the theories of science of Robert Grosseteste, Thomas Aquinas, Duns Scotus, William of Ockham, Marsilius of Inghen, and Pierre dAilly. Confronting the scientific status of theology, Lee argues that the main issue is how to provide a rational ground for existing singulars. The book exposes how, on the eve of modernity, existing singulars were freed from the constraints of rational ground.

The Force of Reason and the Logic of Force investigates the concept of force through various 'episodes' in the history of philosophy.

The book looks at figures who reduce force to something other than itself as well as figures who develop a 'logic of force' that allows them to trace the operation of force without such a reduction.

The Thought of Matter advances current debates around materialism, arguing that matter is the 'other' of thought and, therefore, requires a method that allows that other to emerge in thought without being appropriated by it.
