INVINCIBLE IGNORANCE

Definition

Lack of knowledge, either of fact or law, for which a person is not morally responsible. This may be due to the difficulty of the object of the knowledge, or scarcity of evidence, or insufficient time or talent in the person, or any other factor for which he is not culpable. (Etym. Latin in, not + vincibilis, easily overcome: invincibilis.)
