“It is inconceivable that anything should be existing. It is not inconceivable that a lot of people should also be existing who are not interested in the fact that they exist. But it is certainly very odd.”

“Divorce. Its existence and use should be determined only by the interests of the children.”

Individual Liberty (1926), Anarchism and Crime
Context: Where crime exists, force must exist to repress it. Who denies it? Certainly not Liberty; certainly not the Anarchists. Anarchism is not a revival of non-resistance, though there may be non-resistants in its ranks. The direction of Mr. Ball's attack implies that we would let robbery, rape, and murder make havoc in the community without lifting a finger to stay their brutal, bloody work. On the contrary, we are the sternest enemies of invasion of person and property, and, although chiefly busy in destroying the causes thereof, have no scruples against such heroic treatment of its immediate manifestations as circumstances and wisdom may dictate. It is true that we look forward to the ultimate disappearance of the necessity of force even for the purpose of repressing crime, but this, though involved in it as a necessary result, is by no means a necessary condition of the abolition of the State.
