But ANY part of the language system is worth studying. It is the attitude of the educator, more than the nature of the subject matter itself which is deserving of closer attention in determining success in the classroom, and for these lessons specifically, I think. I'm very interested in exploring imaginative ways of responding to conflict, generally. This is especially of value in reinforcing one's ability to reason, to evaluate information both subjectively and objectively, and to make choices. The cumulative experience, of recognizing these patterns in language, strongly supports the development of critical thinking in general, and of problem-solving skills in particular.

It would be difficult to pursuade me that it not a good and useful thing in practice, to stress the extraordinary value in one's acquiring, now, the ability to exercise this power, at will. Whatever we do, we are increasing the options available to students and allowing them to choose from those options. Swearing adds poewr to whatever you say, even if it only makes you feel more powerful. It is the language of the powerless, the less powered and the disadvantaged. Teaching it to students can empower them in certain situations.
