Types of Ignorance

By Maeve Maddox

As a teacher, I am always pained when I hear “ignorant” used as an insult.

ignorance: n. lack of knowledge

Everyone is born ignorant into the world. The word ignorance is from Latin ignorantia. The prefex in- means “not”; Old Latin gnarus means “aware, acquainted with.” Mere ignorance is nothing to be ashamed of. Ignorant is not a synonym for “stupid.”

Catholic theology recognizes three categories of ignorance:

invincible ignorance: lack of knowledge that a person has no way to obtain

vincible ignorance: lack of knowledge that a rational person is capable of acquiring by making an effort

nescience: lack of knowledge that doesn’t matter in the circumstances (from Latin ne-, “not” plus scire, “to know.”

In Catholic theology, invincible ignorance, “whether of the law or the fact, is always a valid excuse and excludes sin.”

In the secular realm, however, ignorantia juris non excusat, “ignorance of the law does not excuse.”

Logicians have adopted the term “invincible ignorance” to mean “the fallacy of insisting on the legitimacy of one’s position in the face of contradictory facts.”

Here’s a lengthier definition given in a Wikipedia article:

invincible ignorance: a deductive Fallacy of Circularity where the person in question simply refuses to believe the argument, ignoring any evidence given. It’s not so much a fallacious tactic in argument as it is a refusal to argue in the proper sense of the word, the method instead being to make assertions with no consideration of objections.

Fitness expert Greg Glassman has this recommendation for dealing with invincible ignorance:

some simply cannot be swayed toward your way of thinking, so don?t try. ?you?re probably best to walk away from a pointless debate.
