“Youth ages, immaturity is outgrown, ignorance can be educated, and drunkenness sobered, but stupid lasts forever.”
“Not ignorance, but ignorance of ignorance is the death of knowledge.”
“To be ignorant of one's ignorance is the malady of the ignorant.”
“We can ignore reality, but we cannot ignore the consequences of ignoring reality.”
“We lived, as usual by ignoring. Ignoring isn't the same as ignorance, you have to work at it.”
