“The problem ain't what people know. It's what people know that ain't so that's the problem.”
“It's not what we don't know that hurts. It's what we know that ain't so.”
“Maybe there ain't no sin and there ain't no virtue, they's just what people does. Some things folks do is nice and some ain't so nice, and that's all any man's got a right to say.”
“What gets us into trouble is not what we don't know. It's what we know for sure that just ain't so.”
“The problem is [people] know what matters, but they don't choose it.”
“The whole problem with people is they don't know what matters and what doesn't.”
