Abstract

The concept of similarity is used to exemplify in what way Wolff conveys a new content to a traditional concept. Similarity functions in his system as a link between a priori ontology and a posteriori knowledge, because it is similarity on which relies Wolff's theory of abstraction, his doctrine of order (which also includes the concepts of perfection, of space and time) and even his characterization of human faculties of knowing (e.g. expectation of similar events, wit and penetration)
