" Evil, for Objectivism, means the willful ignorance or defiance of reality. This has to mean: that which cannot deal with reality, that which is whim-ridden, context-dropping, self-contradictory. Evil is consistent in only one regard: its essence is consistently at war with all the values and virtues human life requires. "

― Leonard Peikoff , Objectivism: The Philosophy of Ayn Rand
