In 1978, Mijuskovic examines Franz Brentano’s Psychology from an Empirical Standpoint in an article entitled “Brentano’s Theory of Consciousness.” The reader will immediately notice a change in tone Mijuskovic takes from his usual formulation of premises and uses of the simplicity argument. He uses Brentano’s language to show two key aspects of his theory of consciousness. Despite this change of approach, the conclusions about Brentano’s treatment of the immateriality of consciousness run parallel to previous formulations of the simplicity argument. Mijuskovic examines the immortality of the soul and the unity of consciousness within Brentano’s work; thus, referring to the first and second uses of the simplicity argument.
