  The author recalls general tendencies of the "mathematization" of the
sciences and derives challenges and tentative obstructions for a successful
merger of mathematics and physics on fancied steps towards "Quantum Gravity".
This is an edited version of the author's opening words to an international
workshop "Quantum Gravity: An Assessment", Denmark, May 17-18, 2008. It
followed immediately after the Quantum Gravity Summer School 2008, see
