1842–1906 Idealism & Process Philosophy Philosophy of the Unconscious

He elevated the Unconscious from a psychological quirk to the hidden metaphysical will steering the whole of reality.

Karl Robert Eduard von Hartmann (1842–1906) was a German metaphysical philosopher known as ‘the philosopher of the unconscious.’ His major work, Die Philosophie des Unbewussten (Philosophy of the Unconscious, 1869), became widely read across Europe and made the Unconscious a central metaphysical principle.

He sought to synthesize Schopenhauer’s irrational Will with Hegel’s rational Idea, treating both as aspects of one unconscious absolute. His pessimistic yet developmental view of the world process drew both popularity and sharp critique in his era.
