Sigmund FreudOur knowledge of the historical worth of certain religious doctrines increases our respect for them, but does not invalidate our proposal that they should cease to be put forward as the reasons for the precepts of civilization. On the contrary! Those historical residues have helped us to view religious teachings, as it were, as neurotic relics, and we may now argue that the time has probably come, as it does in an analytic treatment, for replacing the effects of repression by the results of the rational operation of the intellect.
Sigmund FreudOne might compare the relation of the ego to the id with that between a rider and his horse. The horse provides the locomotor energy, and the rider has the prerogative of determining the goal and of guiding the movements of his powerful mount towards it. But all too often in the relations between the ego and the id we find a picture of the less ideal situation in which the rider is obliged to guide his horse in the direction in which it itself wants to go.
