Freud's psychological approach explains conscience as the superego—the internalized voice of parents and society living in our unconscious mind. The superego develops around ages 3-6 through the Oedipus Complex, when children identify with their same-sex parent and internalize their rules and moral codes.
Conscience is not divine (as Aquinas said) but psychological: it's a learned system of guilt and shame imposed by parents. The Id (primal desires) constantly pushes for gratification, the Superego (internalized rules) condemns those desires, and the Ego (rational self) mediates between them. When we act against the superego's rules, we feel guilty—not because we've violated God's law, but because we fear parental disapproval internalized in our psyche.
Freud explains conscience as a psychological mechanism, not a spiritual or rational one. Conscience is the superego—an internalized system of parental and social rules that operates largely in the unconscious mind.
Around ages 3-6, the child enters the phallic stage and develops the Oedipus Complex:
To resolve the conflict and reduce anxiety, the boy identifies with his father. By becoming like the father, the boy:
Step 1: The Id Desires
An impulse arises (aggression, sexuality, selfishness).
Step 2: The Superego Objects
The internalized parental voice says "That's wrong!"
Step 3: Anxiety and Guilt
The conflict between Id and Superego creates anxiety and guilt. The ego uses defence mechanisms to manage this conflict.
Step 4: Behavior Adjustment
To reduce guilt and anxiety, the person obeys the superego (acts morally).
If the superego is too strong or punitive, it can cause:
If the superego is too weak, it can cause:
"The superego is the ethical component of personality. It contains internalised ideals from parents and society, and it opposes the id's desires. The superego develops around ages 3-6 and causes us to feel guilt when we transgress. Conscience is essentially the superego, the internalized voice of parental authority judging our actions."
Freud's foundational statement of how conscience develops psychologically through internalization of parental authority.
"The superego is the psychological presence of the parental authority, always observing and judging the actions and intentions of the ego. It is this internal regulator that compels the adult to adhere to social rules, feel remorse for misdeeds, and strive for perfection."
This captures how the superego functions as an internalized parent guiding moral behavior through guilt and shame.
Freud replaces the idea of God-given conscience with a psychological superego—the internalized voice of parental and social authority.
Id (primal desires), Ego (rational mediator), and Superego (internalized morality) constantly interact to shape behavior.
Ages 3-6: child identifies with same-sex parent and internalizes their rules through resolution of the Oedipus Complex and castration anxiety.
Conscience (punishes with guilt and shame) and Ego Ideal (rewards with pride when living up to internalized standards).
We feel guilty because the superego is the internalized voice of the feared/respected parent, not because we've violated objective moral law.
Conscience operates in the unconscious, not through conscious reasoning like Aquinas suggested—moral behavior is driven by unconscious processes.
Too much guilt leads to neurosis, anxiety, and depression; too little leads to antisocial behavior without remorse.
Unlike Aquinas's objective synderesis, Freud's superego depends on your particular upbringing—making conscience culturally and individually relative.
| Aspect | Aquinas (Theological) | Freud (Psychological) |
|---|---|---|
| Source of Conscience | Divine—God gives reason/synderesis | Psychological—internalized parental authority |
| Is Conscience Rational? | Yes—conscience applies reason to God's law | No—conscience is mostly unconscious, non-rational |
| How Does It Develop? | Innate synderesis + education/experience | Through Oedipus Complex (ages 3-6) via identification with same-sex parent |
| Role of Parents | Parents educate conscience through teaching | Parents imprint moral rules directly into unconscious via fear/castration anxiety |
| Is Conscience Infallible? | Synderesis is infallible; conscientia is fallible | Superego can be harsh, weak, or distorted by upbringing |
| Guilt | Result of violating synderesis/God's law | Result of Id-Superego conflict; fear of parental punishment internalized |
| Universal or Relative? | Universal—all humans have the same primary precepts | Relative—depends on what parents taught you |
| Can Conscience Be Wrong? | Yes, if conscientia makes mistakes | Yes, if superego is harshly punitive or weak |
