The ego is the part of the id modified by the direct influence of the external world via the perceptual-consciousness system, committed to the reality principle and representing reason and prudence, whereas the id remains governed by the pleasure principle and contains the passions; their relation is aptly illustrated by the rider and the horse.

By Sigmund Freud, from The Ego and the Id

Key Arguments

  • Freud states that "the Ego is the part of the Id which, through direct influence of the outside world with the pcpt-cs’ intercession, has changed, in a sense, a continuation of the surface differentiation," defining the ego as a transformed segment of the id.
  • He adds that the ego "seeks to bring to bear the outside world’s influence on the Id and its motives, and is committed to the Reality Principle in lieu of the Pleasure Principle, which reigns unchecked in the Id," contrasting their governing principles.
  • He writes: "Perception plays a role for the Ego which falls to instinct in the Id. The Ego represents what we can call reason and prudence, in contrast to the Id, which contains passions," mapping them onto familiar vernacular distinctions.
  • He notes the ego’s control over action: "The Ego’s functional importance is reflected in the fact that normally it is granted control over the approaches to motility."
  • He introduces the famous metaphor: "The Ego thus resembles, vis-a-vis the Id, the rider, which reins the horse’s superior power," but stresses that the rider "often leaving no choice but to drive it where it wants to go, just as the Ego fosters the will of the Id into actions as if of the Id’s own will," emphasizing the ego’s relative, not absolute, mastery.

This analogy goes a bit further. As the rider, it doesn’t want to separate from the horse, often leaving no choice but to drive it where it wants to go, just as the Ego fosters the will of the Id into actions as if of the Id’s own will. 44 There seems yet another factor as the influence of the pcpt -System encouraged the Ego’s development and its isolation from the Id.
