“The prison population consists of heterogeneous elements; but, taking only those who are usually described as 'the criminals' proper, and of whom we have heard so much lately from Lombroso and his followers, what struck me most as regards them was that the prisons, which are considered as preventive of anti-social deeds, are exactly the institutions for breeding them. Every one knows that absence of education, dislike of regular work, physical incapability of sustained effort, misdirected love of adventure, gambling propensities, absence of energy, an untrained will, and carelessness about the happiness of others are the causes which bring this class of people before the courts. Now I was deeply impressed during my imprisonment by the fact that it is exactly these defects of human nature--each one of them--which the prison breeds in its inmates; and it is bound to breed them because it is a prison, and will breed them so long as it exists. ”

“Schools and schoolmasters, as we have them today, are not popular as places of education and teachers, but rather prisons and turnkeys in which children are kept to prevent them disturbing and chaperoning their parent.”

“One thing about which fish know exactly nothing is water, since they have no anti-environment which would enable them to perceive the element they live in.”

“It needs but one foe to breed a war, and those who have not swords can still die upon them.”

“One cannot bring children into a world like this. One cannot perpetuate suffering, or increase the breed of these lustful animals, who have no lasting emotions, but only whims and vanities, eddying them now this way, now that.”

“Happy is the civilization which can breed men accustomed from infancy to regard certain at least of the ego's natural activities as unthinkable.”
