Ladder of Meaning: Meaning, Meaning Into Shared Meaning, and Shared Meaning Into Truth
Human beings live and cooperate through signals. But signals alone are ambiguous. We require disambiguation to turn noise into meaning, meaning into shared meaning, and shared meaning into truth. Each step of this ladder increases the reliability of communication, yet each step also carries risks when the higher properties are missing. By distinguishing these levels, and understanding both their failure modes and their remedies, we can better measure, test, and preserve the integrity of language, law, and civilization.
-
Definition: A raw stimulus, undifferentiated in itself.
-
Function: Provides the material input for perception.
-
Limitation: Signals are ambiguous until disambiguated.
-
Definition: The sufficiency of disambiguation for identification.
-
For the individual: A signal acquires meaning when it can be disambiguated into a stable identity (a referent).
-
Example: Recognizing that a shape in vision corresponds to “a chair.”
-
Note: Meaning at this level need not be true, only sufficient for the person’s mental coordination.
-
Definition: The sufficiency of disambiguation for agreement between two or more parties.
-
Function: Coordinates social reference through common symbols.
-
Example: Two people agree that the word “chair” refers to the same object type.
-
Note: Shared meaning enables communication, but still does not guarantee truth.
-
Definition: Meaning that has been tested, warranted, and verified against reality.
-
Function: Truth transforms shared meaning into knowledge by correspondence with reality under operational test.
-
Example: “This chair will hold my weight” can be tested by sitting on it. If it holds, the meaning (chair as seat) and its properties are true.
-
Note: Truth is a separate property from meaning. Meaning is necessary for communication; truth is necessary for reliability and responsibility.
-
Everyday Life: Most communication rests at the level of meaning or shared meaning, which suffices for coordination but not certainty.
-
Law and Science: Truth is required, since decisions and predictions must be warranted under test.
-
AI and LLMs: Current models produce meaning (individual and shared) but not truth, since they cannot guarantee testability or correspondence.
-
Civilization: Confusing meaning with truth invites sophistry, propaganda, and institutional collapse.
