Quotations
Panopticon: or, the inspection-house. Containing the idea of a new principle of construction applicable to any sort of establishment, in which Persons of any Description are to be kept under inspection. And in particular to: penitentiary-houses, poor-houses, prisons, manufactories, houses of industry, mad-houses, work-houses, hospitals, and schools. .Now as to safe custody. Upon the Panopticon plan at least, absolute solitude is equally unnecessary to this purpose. Towards effecting an escape, what can two or three do more than one, confined as they are by iron grates while they are within the prison, and by walls when they are without? and in either case, never out of the eye of an inspector, who is armed and out of reach of attack, and within reach of whatever assistance he can desire? . .I look upon escape out of a Panopticon, I have said so over and over, as an event morally impossible. But suppose it otherwise — how great the additional security which an expedient thus simple would afford!
