Abstract

In this article we present a clarification of the problem of intentionality that combines the psychologistic and phenomenological-logical traditions, but at the same time is naturalistic. Laird Addis's theory of intentionality, which we try to reconstruct here, falls into this category. He explains intentionality by using Ockham's concept of a natural sign. Such a sign is a property of a mental act. According to Addis, there are important arguments for the existence of such signs: scientific, phenomenological, and dialectic.
