Freud wrote his Psychology for Neurologists (which Strachey called A Scientific Project) in 1895. He wrote it in a feverish state within a month, yet quickly buried it. His intensity in writing it and in suppressing it has not been explained, but intriguing hints about it from Freud's correspondence with Fliess are discussed here. The work remains, however, foreshadowing many of Freud's important psychological concepts. Further, although it is often dismissed because of archaic neurological ideas, many neurological guesses that Freud presented in Psychology for Neurologists are in keeping with neuroscience of today. Aspects of mechanisms of the brain, understanding dreams, developmental perspectives and clinical ramifications all relate to what Freud said in this draft for a monograph.
