Homonculus Fallacy

/ˌhɒməˈnkjʊləs ˈfæləsi/

Definitions

  1. (n.) A logical error in legal reasoning that involves assuming the existence of a fully formed entity to explain a complex process, often used to critique explanations of mental states or consciousness in law.
    The judge criticized the expert witness for committing the homonculus fallacy by assuming a tiny legal mind controls all decisions.

Commentary

Avoid the homonculus fallacy in legal arguments by not presuming unexplained entities or mechanisms; clarify the basis of mental or decision-making processes without infinite regress.
