Eastern Daylight Time, rpaul@xxxxxxxx writes: 'Pons asinorum,' literally 'bridge of asses' was scholarly cant for the fifth proposition of the first book of Euclid's Elements. It was so called because inept students ('dumb asses') had difficulty understanding its proof, i.e., getting across it. It's been generalized to mean any intellectual difficulty which separates the inept from the ept. See: http://aleph0.clarku.edu/~djoyce/java/elements/bookI/propI5.html ---- And then there's Proclus citing this Epicurean laughing at Euclides. Oddly, Clark, in the site referred to by Mutton college prof, writes: >This proposition has been called the Pons Asinorum, or Asses' Bridge. >Whether this name is due to its difficulty (which it isn't) I wonder if Karle Trogge's "Witters" would say that _that_ is a sentence?! Not to me. I cannot understand the _logical form_ behdn It is not clear whether the name is due to its difficulty -- which it isn't. It isn't what? I hope she doesn'e mean 'difficult' because then she is, friendly, an ass. >or the resemblance of its figure to a bridge is not clear. Very few of the propositions in the >Elements are known by names. That's not so true. My mother calls the first, "Maria", the second, "Maria Maria", and the third, "Maria Maria Maria" -- We love to sing, "We just meant a girl named Maria", meaning the first proposition. The fourth proposition we call Juan. Cheers, JL Speranza Buenos Aires, Argentina **************Download the AOL Classifieds Toolbar for local deals at your fingertips.
