Ethics

Quick Facts

• Full title: Ethics, also called Scito te ipsum or Know Yourself
• Author: Peter Abelard
• Date: late 1130s, probably around 1138-1139
• Language: Latin
• Kind of work: moral theology and philosophical ethics
• Main question: what makes a person guilty before God?
• Main answer: sin is not the outward deed by itself. Sin is knowingly consenting to what one believes is wrong.

The Problem

Abelard is trying to answer a practical religious question: when has a person actually sinned? That mattered for confession, penance, preaching, and church discipline. A simple answer would say: bad act equals sin. Abelard thinks that answer is too crude.

People can be tempted without choosing the temptation. They can be forced into an outward act. They can also plan an evil deed and fail only because circumstances stop them. So Abelard asks what the real fault is: desire, pleasure, outward action, result, or inward consent?

In One Minute

Ethics argues that God judges moral guilt from the inside. The outward deed matters for human courts, repair, example, and public order. But the deed alone does not show whether the person is guilty before God.

Abelard's central claim is that sin is consent. Consent means inwardly giving yourself over to a desire or plan. Intention means what you are aiming at and why. If two people both consent to adultery, but only one gets the chance to carry it out, Abelard thinks both are guilty in the same basic way before God.

This does not mean "good intentions make anything okay." Conscience is a person's judgment about what God or right reason requires, and Abelard thinks it must be educated. A mistaken conscience can excuse only when the ignorance is not careless.

The Main Argument

Abelard separates the pieces that often get lumped together under "sin." Vice is a bad tendency, such as a strong pull toward anger, lust, or pride. Desire is wanting something. Pleasure is felt enjoyment. Consent is the inward approval that says yes. The deed is the outward act.

Vice, desire, and pleasure are not automatically sins, because they can arise without being chosen. A person may feel an impulse and hate having it. Moral blame starts when the person consents: when the mind accepts the wrong as something to be pursued.

This is why Abelard defines sin as contempt or scorn for God. He does not mean that every sinner consciously says, "I despise God." He means that knowingly choosing against what one takes to be God's will treats God as less important than the desired thing.

Abelard also separates divine judgment from human judgment. God can see intention. Human beings usually cannot. Courts may still punish harmful deeds to protect others or warn the community. But the deepest moral question is what the agent consented to.

The hard case is conscience. Abelard says that acting against conscience is sinful, because it means choosing what one believes to be wrong. But conscience is not a private magic shield. It must be guided by love of God and neighbor, and by a rational rule like the Golden Rule. Ignorance excuses only when the person was not negligent. Negligence means failing to seek the truth when you had a real duty and chance to seek it.

Key Ideas With Examples

• Intention: the point of an action as the agent understands it. Giving money to help is different from giving money only to be praised.
• Consent: inward approval of a desire or plan. Anger can rise without consent; consent begins when the person embraces revenge as something to do.
• Sin: knowingly consenting to what one believes offends God. Sin is the inward turning of the person against the good they recognize.
• Vice: a settled weakness or bad tendency. A quick temper is dangerous, but the person sins when they consent to cruelty.
• Pleasure: bodily or emotional enjoyment. Abelard uses involuntary pleasure to show that feeling is not the same as choosing.
• Conscience: the inner judgment that says "this is right" or "this is wrong." It binds the person, but it must be formed by reason, love, and responsible learning.
• Penance and confession: practices of repentance and repair. Abelard pushes confession inward: not only "what happened?" but "what did I knowingly consent to?"
• Human justice and divine justice: human justice often judges deeds from public evidence. Divine justice can judge consent, intention, ignorance, and negligence.

Why It Matters

Ethics is one of the clearest medieval statements of intentionalism: the view that moral worth depends centrally on intention. Abelard does not invent the Christian concern with the inner life, but he makes the distinction between desire, consent, and deed unusually sharp.

The work also shows Scholasticism at work. Abelard takes a religious problem and breaks it into careful distinctions. Instead of saying "sin is bad action," he asks which part of action actually carries guilt.

It matters for confession and later moral psychology because it treats action as layered. The title Know Yourself is not decoration. To repent honestly, a person must know the difference between temptation, fear, habit, consent, and excuse-making.

Proponents, Critics, and Opponents

Augustine of Hippo is an important background figure. Augustine had already made love, will, and inward conversion central to Christian ethics. Abelard inherits that inward focus, but he narrows guilt more sharply around consent.

Sympathetic readers value Abelard for taking moral responsibility seriously. His account explains why coercion, accident, and non-negligent ignorance can change blame. It also explains why a failed evil plan can still reveal real guilt.

Critics worry that Abelard goes too far. If outward deeds are morally indifferent in themselves, does wrongdoing depend too much on private intention? If conscience is central, does a sincere but badly mistaken person become too easy to excuse? Abelard answers by appealing to negligence, love of neighbor, and God's ability to judge the heart, but the pressure remains.

The work sits near Abelard's wider disagreements with the moral theology associated with Anselm of Canterbury. Anselm's Cur Deus Homo explains salvation through satisfaction for offense against divine honor. Abelard's moral theology often shifts attention toward inward love, consent, and the transformation of the sinner.

Later scholastic thinkers, including Thomas Aquinas, keep intention important but usually refuse Abelard's strongest-sounding claim that the outward act is morally neutral by itself. They give moral weight to intention, object, circumstances, habit, and consequences together.
