Freudas ideas remain influential even when they seem implausible. Why might this be?

Commentary:
Two short introductions are recommended:
Anthony Storr, Freud: A Very Short Introduction [This covers all aspects of Freudas work, and is critical in places]
D. Stafford-Clark, What Freud Really Said [focuses more on Freud the psychoanalyst, and is more expository]
B. Morris, Western Conceptions of the Individual, pp. 79-101 [useful very short account]
P. Ferris, Freud: A Life [readable biography].

The essay is for Social Theory”. I want it to be crtitical.
the sources are to be used from bibliography plus 1-2 additional ones.
