Mens Rea
Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
Latin for "guilty mind". Refers to the subjective mental state of the defendant when committing a criminal act (intent, knowledge, recklessness, negligence). Fundamental principle of modern criminal law: "Actus non facit reum nisi mens sit rea" (an act does not make a person guilty unless the mind is guilty).
SCAFFOLDING EFFECT
Reduce cognitive load
Distinguishing evil from error. When judging others' behavior (or one's own mistakes), it is crucial to distinguish between "lack of ability" (unintentional) and "bad motive" (intentional). The former requires training and improvement, the latter requires punishment and prevention. Confusing the two can lead to either excessive blame or excessive leniency.
Anchor fast decisions
The subjective element of a crime, i.e., the mental state (intent or negligence) of the actor when committing a harmful act. The mechanism is that both subjective and objective elements must be unified for a crime to be established.
