Historically, the most terrible things - war, genocide, and slavery - have resulted not from disobedience, but from obedience.
The defiance of established authority, religious and secular, social and political, as a world-wide phenomenon may well one day be accounted the outstanding event of the last decade."On Civil Disobedience" (1969)
A person can become free through acts of disobedience by learning to say no to power. But not only is the capacity for disobedience the condition for freedom; freedom is also the condition for disobedience. If I am afraid of freedom, I cannot dare to say "no," I cannot have the courage to be disobedient. Indeed, freedom and the capacity for disobedience are inseparable; hence any social, political, and religious system which proclaims freedom, yet stamps out disobedience, cannot speak the truth.
