Not Clever

If you’re going to claim one corporate slogan is an informal fallacy, you might as well claim they’re all informal fallacies. For my money, though, no corporate slogan is an informal fallacy, but this is because informal logic have more to do with rhetoric than mathematics. Formal logic is the other way around.

I am teaching informal logic this year and I have collected a number of informal logic textbooks. Each author thinks he is quite clever for going to town on corporate slogans (“Just do it” is special pleading!), but they might as well be deconstructing poems.
