Connecting Justifications, Belief, and Knowledge

The following is a fundamental connection between justification terms and the accessibility relation in a modular model.

It is not part of the general definition—we specify explicitly when we have a modular model meeting this condition.

Definition 3.29 (Justification Yields Belief) We say that justification yields

Example 3.30 Model M1 from Example 3.25 enjoys JYB, whereas M2 from Example 3.28 does not.

We have soundness of modular models with JYB for the corresponding jus­tification logics J, J4, J45, JT, LP, etc. This is because each of the worlds is a basic model. Completeness immediately follows from the corresponding com­pleteness theorems for basic models because each basic model may be re­garded as a modular modelwith a singleton G and empty R.
