Coherence is one of the lowest levels of ontological truth, and a fundamental principle of logic. In order for a theory to be coherent, it must not contradict itself... i.e.- it must not maintain 'X' and 'not X' simultaneously. A theory must be coherent before it can aspire to any higher levels of truth- including the classic 'truth', correspondence truth.
