Quantification and Measurement of Qualities at the Beginning of the Fourteenth Century. The Case of William of Ockham
Abstract
This paper critically examines the debate between William of Ockham and his
contemporary Peter Auriol on how to account for the intension and remission of forms.
Peter Auriol denies that an added degree of a quality such as the theological virtue of charity
could be anything other than something which is neither a universal nor an individual
and which cannot be grasped by intuition, but must be posited in order to account for
the possibility that an accidental form can vary in intensity. Ockham aims at proving that
Auriol’s account is inconsistent. In my opinion, Ockham does not succeed, nor does he
succeed in defending a consistent account of the metaphysics underlying the intension
and remission of forms. Indeed, he conceives of the degree of a quality as a part of the
intensified quality which, while being an individual that is really distinct from the quality
and can be picked out, forms a unity with it in such a way that the union of the degree
and the quality is itself an individual. Ockham fails to distinguish the notion of maximal
resemblance holding between a quality’s degree and the quality from the notion of maximal
resemblance which holds between individuals of the same species. In the end, he is led to
give up the idea that a degree is an individual that can be picked out in order to protect
the core thesis of his nominalism about universals.
