Mathematics and Theology

"This is not mathematics,
it is theology!"

-- Paul Gordan on
a proof by Hilbert 

"There is a pleasantly discursive treatment
of Pontius Pilate's unanswered question
'What is truth?'"

-- H. S. M. Coxeter, 1987, introduction
to Richard J. Trudeau's remarks on
the "Story Theory" of truth
as opposed to
the "Diamond Theory" of truth
in The Non-Euclidean Revolution

Coxeter, whom some have styled "king of geometry," was aware in 1987 of the existence of my 1976 monograph on geometry titled "Diamond Theory." His introduction to Trudeau's remarks, which use that phrase with an entirely different meaning, may, therefore, have been mala fide.

Gordan's exclamation above seems apropos since it turns out that Trudeau's book is, in fact, more about theology than about mathematics. Trudeau quotes approvingly from The Dark Interval: Towards a Theology of Story, a book by former priest John Dominic Crossan apparently first published in 1975. Some details from Trudeau's book:

Crossan is noted for what has been called "narrative theology," (pdf) an approach that views theology as based on stories-- i.e., on lies.

For a similar approach to mathematics, see "Mathematics and Narrative" and "A Mathematical Lie."
