Beauty is Truth and Truth Beauty


Love makes an object beautiful—Eliseo Lagano

Ubi amor ibi oculus est (Where there is love there is vision)—Richard of St Victor

Do you recall John Keats’ enigmatic last two lines in Ode on a Grecian Urn: “Beauty is truth, truth beauty. That is all ye know on earth, and all ye need to know” ?

“But what on Earth did Keats mean?” asked mathematician and author, Martin Gardner (Scientific American, April 2007). Gardner went on to quote T.S. Eliot who called the lines “meaningless” and “a serious blemish on a beautiful poem”. A rather pithy remark, I thought, considering the lines spoke of beauty. Gardner further described how great theorems and great proofs, such as “Euclid’s elegant proof of infinity of primes, have about them what Bertrand Russell described as ‘a beauty cold and austere’ akin to the beauty of great works of sculpture.”

Ian Stewart, a distinguished mathematician at the University of Warwick in England and author of Why Beauty is Truth: a History of Symmetry, suggested that symmetry lay at the heart of beauty. He concluded his book with two maxims: 1) in physics, beauty does not automatically ensure truth, but it helps; and 2) in mathematics beauty must be true—because everything false is ugly.

I really don’t think these guys get it.
