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

S. Freud, a?The Ego and the Superegoa?, *pp 733-738, a?On Object-relations and psycho-sexual stagesa?, *pp. 838-852, a?The Psychopathology of everyday lifea?, pp. 887-895, all excerpted in T. Parsons, E. Shils et al. (eds.), Theories of Society.
Freud, Civilization and its Discontents (1930), *Chapter 2
Freud, Totem and Taboo (1913), reprinted in the Penguin Freud Library, Vol. 13, The Origins of Religion, esp. *pp. 53-70, a?The horror of incesta?.
Freud, *The Uncanny, many reprints including Penguin volume of same title

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.
