"The only thing necessary for the triumph of evil is for good people to do nothing" is attributed to whom?

The quote: “The only thing necessary for the triumph of evil is for good men to do nothing” has been attributed to Edmund Burke. He was an 18th Century British Statesman who was famous for impeaching Warren Hastings, the first de facto Governor-General of India, for crimes and misdemeanors during his time in India. Also, Burke is known for both the book he wrote in 1790 on the French Revolution ("Reflections on the Revolution In France") and for some fairly liberal positions he took towards the American colonies in the late 1700s.

The quote attributed to Burke makes it clear. Good men must oppose the cabals of bad men. Good men cannot pacify their consciences by the delusion that they can do no harm if they take no part and form no opinions about the actions taken by bad/evil men.

Accepting Burke's belief, one may effectively blame any and all suffering in the world, from war to poverty, from oppression to crime, not on evil, but on the unwillingness of good people to lift a finger, utter a word, or to declare an outright rebellion against evil in the world.

Historians, scholars, writers, and others say that evil is an ever-present and static anti-force, and that good, if not directed as a dynamic force, cannot be of any use in eradicating evil. If evil is darkness, and good, light, this means that light must make an effort, trespass obstacles, play the offensive, and not run in the face of darkness. The world will be dark because of the obstruction of light.
