The immense majority of individuals, not only among the ignorant masses but also among the civilized and privileged classes, think and want only what everybody else around them thinks and wants, They doubtlessly believe that they think for themselves, but they are only slavishly repeating by rote, with slight modifications, the thoughts and aims of the other conformists which they imperceptibly absorb This servility, this routine, this perennial absence of the will to revolt and this lack of initiative and independence of thought are the principle causes for the slow, desolate historical development of humanity.
— Mikhail Bakunin
