 The first question (fols. 53r-88v) is whether, from the point of view of the natural philosophy, material things have three constitutive principles only, that is: matter, form, and privation, or not. Sharpe’s answer is affirmative, but he points out that the constitutive principles of material things are three by species and not in number. Indeed, material things have more than three principles in number, but each of them is reducible to matter, or form, or privation.
