In'co-hē'rence or In'co-hē'ren-cy, n.

n. [Fr. incohérence, Sp. incoherencia, It. incoerenza.]

1. The quality of being incoherent; want of coherence or adherence. Boyle.
2. Want of connection; incongruity; inconsistency; want of agreement or dependence of one part on another; as, the incoherence of arguments, facts, or principles.

Incoherence in matter, and suppositions without proofs, put handsomely together, are apt to pass for strong reason. Locke.
