 Sharpe wrote the most interesting treatise on universals of the late Middle Ages other than those of Wyclif and Paul of Venice, arguing about logic and metaphysics, explaining his positions on being and essence, universals, singulars, predication, identity and distinction, and truth and falsity. His tract is very similar to that of Paul of Venice with regard to many metaphysical theses supported, the structure of the work, the textual material utilized, and the opinions discussed. In his Quaestio super universalia Sharpe lists eight opinions on universals (Buridan, Ockham, Auriol, Albert the Great and Giles of Rome, Plato, Duns Scotus, Burley, and Wyclif) and so does Paul of Venice in his Quaestio de universalibus (Ockham, Thomas Aquinas and Giles of Rome, Auriol, Burley, Wyclif, Plato, and two other unidentified realist authors). Yet, there are some noteworthy doctrinal differences between them and the other Oxford realists, which testify to Sharpe’s (and Paul of Venice’s) independence of thought.
