Let us put it, then, that Jeanne d’Arc’s was an advanced case of the mental and bodily constitution exemplified by the relatively small proportion of people, the sane seers of visual hallucinations and hearers of unreal voices. Her thoughts--let us say the thoughts of the deepest region of her being--presented themselves in visual forms, taking the shapes of favourite saints--familiar to her in works of sacred art--attended by an hallucinatory brightness of light [‘a photism’), and apparently uttering words of advice which was in conflict with Jeanne’s great natural shrewdness and strong sense of duty to her parents. ‘She MUST go into France,’ and for two or three years she pleaded her ignorance and incompetence. She declined to go. She COULD resist her voices. In prison at Beaurevoir, they forbade her to leap from the tower. But her natural impatience and hopefulness prevailed, and she leaped. ‘I would rather trust my soul to God than my body to the English.’ This she confessed to as sinful, though not, she hoped, of the nature of deadly sin. Her inmost and her superficial nature were in conflict. It is now desirable to give, as briefly as possible, Jeanne’s own account of the nature of her experiences, as recorded in the book of her trial at Rouen, with other secondhand accounts, offered on oath, at her trial of Rehabilitation, by witnesses to whom she had spoken on the subject. She was always reticent on the theme. The period when Jeanne supposed herself to see her first visions was physiologically critical. She was either between thirteen and fourteen, or between twelve and thirteen. M. Simeon Luce, in his ‘Jeanne d’Arc a Domremy,’ held that she was of the more advanced age, and his date (1425) fitted in with some public events, which, in his opinion, were probably the occasions of the experiences. Pere Ayroles prefers the earlier period (1424) when the aforesaid public events had not yet occurred. After examining the evidence on both sides, I am disposed to think, or rather I am certain, that Pere Ayroles is in the right. In either case Jeanne was at a critical age, when, as I understand, female children are occasionally subject to illusions. Speaking then as a non-scientific student, I submit that on the side of ordinary causes for the visions and voices we have: 1. The period in Jeanne’s life when they began. 2. Her habits of fasting and prayer. 3. Her intense patriotic enthusiasm, which may, for all that we know, have been her mood before the voices announced to her the mission. Let us then examine the evidence as to the origin and nature of the alleged phenomena.
