1.
Running means to run.
Horses run.
Therefore swiftly running horses run.

2.
The Don is a river.
Swiftly flows the Don.
Swiftly run the horses.
Therefore Don is a horse.
Therefore a horse is a river.
Hippo means horse,
Patamos means river.
Therefore horses are hippopatomases.
So are rivers.

JL would support this logic if he were still subscribing.

(A) Horses run swiftly, so horses run.

That is, it clearly seems to follow from their running swiftly that they run.

Yet it's extremely difficult to formalize this straightforward inference (without adding a prima facie otiose premise).

The best attempts to put (A) in recognizable logical form will win three weeks at the Mutton College Logic Camp, in Sheepskin, Nebraska. Camp begins July 3.
