In Praise of Prejudice: The Necessity of Preconceived Ideas (Hardcover)
by Theodore Dalrymple
"Today, the word prejudice has come to seem synonymous with bigotry; therefore the only way a person can establish freedom from bigotry is by claiming to have wiped his mind free from prejudice.

The attempt to eradicate prejudice has several dire consequences for the individual and society as a whole.
