Philosophy of the Unconscious of the scales, and his 'World-process' in the other. There are some who believe they weigh equally; for in each scale there is an evil word—and a good joke." Hartmann's work has been seen as preparing the way for Freud's later theory of the unconscious. Freud consulted "Philosophy of the Unconscious" while writing "The Interpretation of Dreams" (1899), in which he called Hartmann the firmest opponent of the theory that dreams are wish fulfillments. The philosopher Hans Vaihinger was influenced by "Philosophy of the Unconscious", relating in his "The Philosophy of 'As if'" (1911) how it led him to Schopenhauer.

Insight is the first asset gained by the clinical use of dreams for both the therapist and the client.
