Abstract

New approach to ontological status of Plato’s ideas is one of the most important achievements of Hermann Lotze. In his Logic Lotze argues that ideas have not existence but are valid as predicates in propositions. The key concept in this line of thought is validity that expresses one of the modi of reality . Analysis of its ontological assumptions allows to introduce a model of intentionality which combines semantic inferentialism of conceptual contents with non-conceptual determination of the limits of language expression and its rationality
