The Fourth Figure
"In Aristotelian syllogistic (Prior Analytics, Bk I Caps 4-7), syllogisms are divided into three figures according to the position of the middle term in the two premisses. The fourth figure, in which the middle term is the predicate in the major premiss and the subject in the minor, was added by Aristotle's pupil Theophrastus and does not occur in Aristotle's work, although there is evidence that Aristotle knew of fourth-figure syllogisms."

“July 4. Statistics show that we lose more fools on this day than in all the other days of the year put together. This proves, by the number left in stock, that one Fourth of July per year is now inadequate, the country has grown so.”

“And they lie like wedges,
Thick end to thin end and thin end to thick end,
And are a figure of the way the strong
Of mind and strong of arm should fit together,
One thick where one is thin and vice versa.”
—Robert Frost (1874–1963)
