“Probably the only place where a man can feel really secure is in a maximum security prison, except for the imminent threat of release. The problem of recidivism ought to have shown young men like John Greenaway just what sort of a notion security is, but there is no indication that he would understand it. Security is when everything is settled, when nothing can happen to you; security is the denial of life. Human beings are better equipped to cope with disaster and hardship than they are with unvarying security, but as long as security is the highest value in a community they can have little opportunity to decide this for themselves.”
