Well, obviously the fore-fathers of modern human psychology have no relevance in hamster society. However Jung has some excellent theories on Archetypes. Obviously hamsters developed past the need for such primative individuality many eons ago. It is useful to be able to 'pigeon-hole' humans though.
Freud was indeed brilliant in his new way of thinking, unfortunately he was too close minded and narrow focused to achieve true brilliance. For better views on human psychology read "Hamsters and human observation" by Furie et al, published 1996 by Rodent press.
