Ignorance can be cured, but stupidity is forever.
Politics, these days, is no occupation for an educated man, a man of character. Ignorance and total lousiness are better.
Youth ages, immaturity is outgrown, ignorance can be educated, and drunkenness sobered, but stupid lasts forever.
Most ignorance is vincible ignorance. We don’t know because we don’t want to know.
Facts do not cease to exist because they are ignored.
Obstinate people can be divided into the opinionated, the ignorant, and the boorish.
But feelings can’t be ignored, no matter how unjust or ungrateful they seem.
Not ignorance, but ignorance of ignorance is the death of knowledge.
The evil that is in the world almost always comes of ignorance, and good intentions may do as much harm as malevolence if they lack understanding.
