An utterance may initially appear to unite mutually opposed descriptions, while the full context reveals a particular standpoint under which they can be coherently considered together. The temporary surprise followed by recognition of the intended relation can enhance attention and refinement.
The incompatibility must be intelligibly resolved; simply juxtaposing contradictory or unrelated assertions is not an accomplishment of rhetoric.
