" The ancient Romans would call the Ironman’s brand appeal argumentum a fortiori, “argument from strength.” Its logic goes like this: if something works the hard way, it’s more likely to work the easy way. Advertisers favor the argument from strength. Years ago, Life cereal ran an ad with little Mikey the fussy eater. His two older brothers tested the cereal on him, figuring that if Mikey liked it, anybody would. And he liked it! An argumentum a fortiori cereal ad. "
