Any teacher who puts students to sleep should find another line of work. Anyone who won’t do their job deserves to lose it.

14. CLARKE’S EXPLANATION OF 6 Inductive Reasoning Level 1: Very specific Professor Peppenfefferis a bad teacher; several of his students were sleeping today.

17. CLARKE’S EXPLANATION OF 6 Step6: TheQualifier The rebuttal makes an argument less absolute. Words like “probably”, and “most” are qualifiers. On first glance, one might think this would reduce the effectiveness of an argument. In fact, the opposite is often true. I think Professor Peppenfeffer is a bad teacher; several of his students were sleeping today. Any teacher who puts students to sleep should probably find another line of work. Anyone who won’t do their job deserves to lose it. You can say he’s senile, but that’s no excuse. Politicians use qualifiers to great effect. It allows them to deny having even made the argument, if the tide of opinion shifts. Note: Not all arguments – not even all effective arguments – have a qualifier.
