Martin is the puppet of hallucinations. Therefore his affection approaches insanity in certain characteristics. "It is for this reason," adds Royer-Collard, "that M. Pinel and myself did not hesitate at first sight to regard this affection as a particular kind of insanity, and it is probable that any other physician would have thought as we do on this point. But if Martin's affection approaches insanity in some particulars, it also differs from it in important and basic respects..." What were they? "In the case of ordinary mental patients, the hallucination of the senses is almost always led up to and brought on by causes which have acted strongly upon their imagination, or disturbed more or less the exercise of their intellectual faculties; it never manifests itself without a special concentration of efforts of the attention or the imagination upon a single idea or upon a particular series of ideas, at least in the period which immediately precedes the vision." Now, in Martin's case, there is nothing like this. He has religious visions, although he had a mind little inclined to the mystic and was even a rather lukewarm Christian. His visions relate to politics, yet he was a stranger to the passions of his fellow citizens and did not read the newspapers. Among ordinary insane, visions are always accompanied by a certain ecstatic exaltation which gives the seer the attitude of the inspired, of the prophet, and never permit him to relate his visions with calmness and tranquillity. Now Martin remains constantly the same. He confides his visions only to his superiors, he appears more annoyed than glorified by them, he relates them with simplicity; he is not turned for one instant from his habitual occupations. Singular coincidences justified certain of the prophecies of Martin: "If it is necessary to make use of the testimony of the officer of gendarmes who accompanied him, Martin announced to him in the morning the visit which M. Pinel was to make in the afternoon, without there being any way in which he could learn of this.... We are equally assured that he had actually written to his brother under date of March 12, to warn him that the authorities were going to have information collected in his neighborhood, in regard to the persons with whom he habitually associated there, while the letter by which these inquiries were ordered was not written until the sixteenth of the same month...." Pinel and Royer-Collard willingly admit that there exist "incontestable occurrences of previsions and presentiments which were later realized by the event." But what appears not less certain "is that these occurrences are met with only in the case of persons who enjoy all their faculties and never among the mentally afflicted. This is a side of our nature which remains inexplicable to us even to this day and which will probably long escape our researches." Finally, Martin is distinguished by his excellent health from other hallucinate insane, who are always
