The most powerful tools of revolution through intention are humility and consciousness.

["F]or it's not possible," [Socrates] said, "for anybody to experience a greater evil than hating arguments. Hatred of arguments and hatred of human beings come about in the same way. For hatred of human beings arises from artlessly trusting somebody to excess, and believing that human being to be in every way true and sound and trustworthy, and then a little later discovering that this person is wicked and untrustworthy - and then having this experience again with another. And whenever somebody experiences this many times, and especially at the hands of just those he might regard as his most intimate friends and comrades, he then ends up taking offense all the time and hates all human beings and believes there's nothing at all sound in anybody.

Without haters, you can't see the level of your progress, that shows you that haters are necessary evil.

[W]hen men have both done and suffered injustice and have had experience of both, not being able to avoid the one and obtain the other, they think that they had better agree among themselves to have neither; hence there arise laws and mutual covenants; and that which is ordained by law is termed by them lawful and just. This they affirm to be the origin and nature of justice;__t is a mean or compromise,between the best of all, which is to do injustice and not be punished, and the worst of all, which is to suffer injustice without the power of retaliation; and justice, being at a middle point between the two, is tolerated not as a good, but as the lesser evil_

Misguided good men are more dangerous than honest bad men. It is because they are seen as good that, in and by good conscience, the mob will always, stubbornly back them without question.

It was important, Dumbledore said, to fight, and fight again, and keep fighting, for only then could evil be kept at bay, though never quite eradicated. . . .
