The opposite of negligence. With negligence, someone acts in a way inconsistent with his duty and that results in a harm to another person that the actor did not intend. With posligence, someone acts in a way, consistent or inconsistent with his duty, that nevertheless results in a good to another person that the actor did not intend. An example: Jones, while driving recklessly, crashed on the property of Smith. The crash causes Smith to attend to the accident, whereupon he finds a buried treasure and becomes exceedingly wealthy. Another example: Jones visits Smith in the hospital to comfort him. Smith improves as a consequence of Jones’ charity, but Smith’s wife is also moved by the Jones’ act, even though Jones did not intend that end for Smith’s wife.I invented this word over the weekend while reading about the Principle of Double Effect.
