Omission in Thomas Aquinas and John of St. Thomas

The aim of this paper is to analyze the doctrine of voluntary omissions in Thomas Aquinas and one of his seventeenth-century commentators, John of St. Tomas. It is argued that both authors made relevant contributions to the philosophical understanding of omissions, which can enrich the current debate on the subject. The paper begins by explaining some problems raised in contemporary philosophy while showing how those same problems were previously discussed in scholastic philosophy. Subsequently, it discusses in detail the contributions of Aquinas and John of St. Thomas.
