Anarchy, when it works to destroy authority in all its aspects, when it demands the abrogation of laws and the abolition of the mechanism that serves to impose them, when it refuses all hierarchical organization and preaches free agreement at the same time strives to maintain and enlarge the precious kernel of social customs without which no human or animal society can exist. Only, instead of demanding that those social customs should be maintained through the authority of a few, it demands it from the continued action of all.
PETER KROPOTKIN, Anarchism: Its Philosophy and Ideal
The history of human thought recalls the swinging of a pendulum which takes centuries to swing. After a long period of slumber comes a moment of awakening. Then thought frees herself from the chains with which those interested -- rulers, lawyers, clerics -- have carefully enwound her. She shatters the chains. She subjects to severe criticism all that has been taught her, and lays bare the emptiness of the religious political, legal, and social prejudices amid which she has vegetated. She starts research in new paths, enriches our knowledge with new discoveries, creates new sciences.
