New! Improved!

"Euclid's edifice loomed in my consciousness 
as a marvel among sciences, unique in its
clarity and unquestionable validity." 
—Richard J. Trudeau in
   The Non-Euclidean Revolution  (First published in 1986)

Readers of this journal will be aware that Springer's new page
advertising Trudeau's book, pictured above, is a bait-and-switch
operation. In the chapter advertised, Trudeau promotes what he
calls "the Diamond Theory of Truth" as a setup for his real goal,
which he calls "the Story Theory of Truth."

For an earlier use of the phrase "Diamond Theory" in
connection with geometry, see a publication from 1977.
