"We acknowledge a theorem's beauty
when we see how the theorem 'fits'
in its place, how it sheds light around itself,
like a Lichtung, a clearing in the woods."
— Gian-Carlo Rota, Indiscrete Thoughts
Here Rota is referring to a concept of Heidegger.
Some context—
"Gestalt Gestell Geviert: The Way of the Lighting,"
by David Michael Levin in The Philosopher's Gaze
