“If only you could really use a fail-proof system to know who was worth keeping and who needed to be thrown away. It would make it so much easier to move through the world, picking and choosing what connections to make, or whether to make any at all.”

Attributed to Karl Marx, a composer with the same name.

The Paris Review interview
Context: Goethe called his work one big confession, didn’t he? Looking at his work in the broadest sense, you could say the same of Shakespeare: a total self-examination and self-accusation, a total confession—very naked, I think, when you look into it. Maybe it’s the same with any writing that has real poetic life. Maybe all poetry, insofar as it moves us and connects with us, is a revealing of something that the writer doesn’t actually want to say but desperately needs to communicate, to be delivered of. Perhaps it’s the need to keep it hidden that makes it poetic—makes it poetry. The writer daren’t actually put it into words, so it leaks out obliquely, smuggled through analogies. We think we’re writing something to amuse, but we’re actually saying something we desperately need to share.
