Modifiers of Human Acts

Aug 9, 2025

Overview

This lecture discusses the "modifiers of human acts," focusing on how various factors influence a person's moral accountability by affecting knowledge and voluntariness in actions.

Modifiers of Human Acts

  • Modifiers of human acts are factors or conditions that affect a person's mental or emotional state when choosing to act.
  • These modifiers are also called "obstacles," as they can lessen or prevent full knowledge or free will in human actions.
  • Modifiers may increase, decrease, or eliminate a person’s moral accountability for an action.

Types of Modifiers: Ignorance

  • Ignorance is defined as the absence of necessary knowledge required in a particular situation.
  • Ignorance is a negative condition, representing a lack of knowledge.
  • There are two main types: Vincible Ignorance and Invincible Ignorance.

Vincible Ignorance

  • Vincible ignorance can and should be overcome with reasonable effort.
  • It is present when a person could know the truth but fails to do so due to negligence or avoidance.
  • Three subtypes:
    • Simple Vincible Ignorance: Some effort is made to gain knowledge, but not enough; the person is still somewhat responsible.
    • Grass or Supine Vincible Ignorance: No effort is made to overcome ignorance; the person is gravely responsible, especially in serious matters.
    • Affected Vincible Ignorance: The person deliberately avoids gaining knowledge to escape responsibility; this increases moral culpability.

Invincible Ignorance

  • Invincible ignorance cannot be overcome with ordinary diligence or reasonable effort.
  • The person is unaware of their lack of knowledge and cannot reasonably be expected to find out.
  • The individual has no responsibility for actions done from invincible ignorance.

Key Terms & Definitions

  • Grass/Supine Vincible Ignorance — No effort to learn what could be known; results in grave responsibility.
  • Affected Vincible Ignorance — Willful avoidance of knowledge to escape responsibility; increases moral culpability.
  • Invincible Ignorance — Ignorance that cannot be overcome; there is no moral responsibility.
