Of Bonhoeffer's three subdivisions of degenerative states the preceding one would as a whole appear to me to be especially deserving of a separate classification. Anyone who has had any experience with insane criminals will recall that group of cases in whom the entire psychosis seems to be more or less centered about a certain idea; in most instances, about the idea of not having received a just trial. These individuals, without showing any intellectual impairment, in fact without showing any characteristic which would fit their mental disturbance into any of the known psychoses, constantly evidence a sort of paranoid habitus, a paranoid trend which is exclusively directed against those who had anything to do with their conviction and safe-keeping. The most trivial occurrences in their environment are endowed by them with a personal note of prejudice. The delay of a letter, the refusal to grant some of their unusual requests, an attendant's accidental failure to sweeten their coffee sufficiently, the slightest deviation from the routine greeting of the visiting physician; in short, any such trivial, insignificant occurrence is at once endowed with a special meaning, and explained in a more or less delusional manner. Yet these individuals can reason in a perfectly rational manner on any subject which is not concerned with their conviction or confinement. They are as a rule intellectually bright and keen, and fail to show any evidence of emotional deterioration. On the contrary, their emotions are of such fine and sensitive nature that incidents which an ordinary individual would overlook entirely, offend them to a marked degree, and are reacted to by them in a very decisive manner. Indeed, one frequently asks himself whether their persecutory ideas deserve to be endowed with the value of actual delusions. I fully agree with Sturrock[12] when he says: "If I refuse to allow a prisoner full scope because he has lifted a knife from the table with which to attack the charge warder, I do not call it a delusion of persecution if he spends the night threatening to murder me because I do not give him justice." One must remember that this is in a measure the normal attitude of the captive towards the captor, and can be seen in a more or less pronounced degree among criminals enjoying a short respite from the law. The essential point here is not the so-called psychosis, but the soil which made the development possible. Not all prisoners, by far, react in this manner to the prison environment. It is only those degenerative individuals who have shown this well-marked paranoic trend all their lifetime, who furnish these cases. As a general rule these conditions are seen in habitual offenders whose entire life has been a round of conflicts with everything they come in contact, and who, outside of prison, figure chiefly in the saloon and gambling house brawls.
