Notes on Meaning

The word casuistry carries a dual meaning. In academic contexts, especially in theology, philosophy, and law, it is a neutral or positive term for a legitimate method of case-based reasoning. In common usage, however, it is almost always pejorative, implying the use of clever but false arguments to deceive. The intended meaning is usually clear from the context.
