" Everything passes, but everything remains. This is a cherished thought for me, that nothing goes away for ever, nothing is lost, but somehow, somewhere, stays. Its worth remains, although we cease to perceive it. And our labors, even if everyone forgot about them, remain and somehow give their fruits. And for this reason, although I regret the past, there is a living sense of its eternity. I did not part with them eternally, but only in time. And it seems to me that all people, whatever they might think, feel the same in the depth of their souls. Without this, life would become senseless and empty. "

― Pavel Florensky , Letters from the Gulag
