What are the most memorable quotes about Quantum Theory of Gravity?

[PRodQuanta]

What are some of your favorite quotes that are about a Quantum Theory of Gravity (be it SST, LQG, etc...). I'm interested in serious along with humorous quotes.

"Anyone who says that they understand Quantum Mechanics does not understand Quantum Mechanics"-Richard Feynman

I guess since this has to do with Quantum Theory by default it has to deal with a quantum theory of gravity.

"Anyone who says that they understand Quantum Mechanics does not understand Quantum Mechanics"-Richard Feynman

I thought that was Niels Bohr...

Niels Bohr, 1927: "Anyone who is not shocked by quantum theory does not understand it."

Richard Feynman, 1967: "Nobody understands quantum theory."

And since we're on the subject of the world being "not only stranger than we know, but stranger than we can know" (which scientist said this?? I remember reading it in a popular science book, but can't remember where or who??) ...

... not strictly regarding quantum physics, but since we're on the subject of human understanding and the subjectivity of perception, one of my very favourite quotes :
"... Einstein’s space is no closer to reality than Van Gogh’s sky. The glory of science is not in a truth more absolute than the truth of Bach or Tolstoy, but in the act of creation itself. The scientist’s discoveries impose his own order on chaos, as the composer or painter imposes his; an order that always refers to limited aspects of reality, and is based on the observer’s frame of reference, which differs from period to period as a Rembrandt nude differs from a nude by Manet." - Arthur Koestler

As a student of the history of science, I find scientific methodology so interesting ... from 'science fiction' to hypotheses to theories, always based on evidence ... so we've got the imagination, and the observations, combined ...

And regarding another of my favourite physics subjects, time, the great Douglas Adams' quote: "Time is an illusion. Lunchtime doubly so."

"Anyon e who is not shocked by the Quantum theorydoesnot understand it"

Below is a littl epoem i came across, composed by Harvard's Howard Georgi, reminding Weinberg...
"Steve weinberg, returning from Texas
brings dimensions galore to perplex us
But the extra one all
are rolled up in a ball
so tiny it never affects us"
it may not directly linked to what u asked for, but hey this is some of the rarest thing u'll ever find:

Below r some more, some of u may admire

" The theory of everything, if u dare to be bold,
Might be something more than a string orbifold.
While some of your leaders have got old and sclerotic,
Not to be trusted alone with things heterotic
Please heed our advice that you are not smitten--
The book is not finished, the last word is not Witten"
-- Glashow
