Could be lyrics, passages, prose, or graffiti. A couple of them I enjoy:
“If I knew what was good for you, I would have gone and done it myself..." Todd Rundgren.
“I hate writing words..." Brian Eno.
“We cannot close our ears..." David Rothenberg.
“Is God willing to prevent evil, but not able? Then he is not omnipotent. Is he able, but not willing? Then he is malevolent. Is he both able and willing? Then whence cometh evil? Is he neither able nor willing? Then why call him God?"
“Through vigilance and strength, we create peace.”
“I’d rather die than beg for a small favor such as my life.”
