"You are probably not aware," he said, "of the remarkable strides that have been made by our medical scientists in Meccania during the last fifty years. The pathological side of psychology has received great attention, with the consequence that our specialists are able to detect mental disease in cases where it would not be suspected by less skilled doctors. I believe I am right in saying that our experts detected the disease now widely recognised as _Znednettlapseiwz_ (Chronic tendency to Dissent) long before it was known in other countries that such a characteristic was in any way connected with brain disease. The microbe has been fully described in the twenty-seventh volume of the _Report of the Special Medical Board_. The first clue to the existence of this disease was discovered during the great war, or perhaps a little later. A number of people persisted in putting forward views concerning the origin of the war, which were totally at variance with the official, and even the Imperial, explanatory statements made for the enlightenment of the public. At the time, it was regarded as just mental perversity. But what led to the discovery was that, after ten, and even fifteen years in some cases, notwithstanding every natural inducement to desist from such perversity, these people deliberately and persistently maintained the objectivity of their hallucinations. Experiments were made; they were under close observation for some years, and at length Doctor Sikofantis-Sangwin produced his theory and confidently predicted that the bacillus would be found in a few years. From that time the path was clear. The disease was most rife some forty years ago, soon after the beginning of Prince Mechow's premiership; but since then it has almost disappeared. You see it is not hereditary, and the normal conditions of Meccanian life are very unfavourable to its development. But coming back to your point, although no doubt this is what has given rise to the calumny that the Special Medical Board uses its powers as an Inquisition, there is not a vestige of truth in the charge. Each case--and the cases are becoming very rare indeed--is investigated on strictly psycho-physiological lines. The patients in all cases are isolated, and placed under observation for some months before any pronouncement is made." "Your explanation is as usual most illuminating," I replied, "and the patience with which you deal with my questions emboldens me to put to you some further difficulties that have been puzzling me." "Proceed," replied Lickrod encouragingly.
