All Implemented Interfaces:

Serializable, Commented, ComprehensiveIdentification, Identified<Identification>, Named

public class Knowledge
extends Object
implements ComprehensiveIdentification

Represents Knowledge according to the classical definition: Justified True Belief (JTB).

Knowledge requires: 1. A Proposition that is True. 2. A Subject who has a Belief in that proposition. 3. Evidence that provides Justification for the belief.

Modernized to implement ComprehensiveIdentification and support dynamic traits and consistent identity.

1.0
