True, and I agree with you: but strictly speaking folk like essius and anosognosia aren't actually trolling sophists. If they point to a flaw in reasoning it's because it's there. In the real world, we accept the small (or large) inconsistencies between our actions and our respective moral/ethical stances under the broad category of 'realpolitik'. Students of morals and ethics often regard realpolitik with horror as a form of consequentialism.

Trying to tell a politics student, or a politician that the end doesn't justify the means will lead to aforementioned politics bod scratching his/her head in a lack of true comprehension: as politics is, as we know, the art of the possible.

We'll learn 'em, and they'll learn us [sic], and all parties may, with luck, profit from the association.
