Die Traumdeutung
The philosopher John Forrester described "The Interpretation of Dreams" as Freud's "masterpiece" in "Dispatches from the Freud Wars" (1997). He suggested that the book could be considered a form of autobiographical writing and compared it to the naturalist Charles Darwin's "On the Origin of Species" (1859). The philosopher Dermot Moran compared the influence that "The Interpretation of Dreams" exerted on psychoanalysis to that which the philosopher Edmund Husserl's "Logical Investigations" (1900–1901) exerted on 20th-century European philosophy in his introduction to the latter work.
