The different religions have never overlooked the part played by the sense of guilt in civilization. What is more, they come forward with a claim...to save mankind from this sense of guilt, which they call sin.
Sigmund FreudThe functional importance of the ego is manifested in the fact that normally control over the approaches to motility devolves upon it. Thus in its relation to the id it is like a man on horse back, who has to hold in check the superior strength of the horse; with this difference, that the rider tries to do so with his own strength while the ego uses borrowed forces.
