"Ecstasy, as we see in cases of acute mental disease, is probably always connected with sexual excitement, if not with sexual depravity. The same association is seen in less extreme cases, and one of the commonest features in the conversation of acutely maniacal women is the intermingling of erotic and religious ideas."[94] This opinion is fully endorsed by Sir Francis Galton:-- "It has been noticed that among the morbid organic conditions which accompany the show of excessive piety and religious rapture in the insane, none are so frequent as disorders of the sexual organisation. Conversely, the frenzies of religious revivals have not infrequently ended in gross profligacy. The encouragement of celibacy by the fervent leaders of most creeds, utilises in an unconscious way the morbid connection between an over-restraint of the sexual desires and impulses towards extreme devotion."[95] Dr. Auguste Forel, the eminent German specialist, points out that-- "When we study the religious sentiment profoundly, especially in the Christian religion, and Catholicism in particular, we find at each step its astonishing connection with eroticism. We find it in the exalted adoration of holy women, such as Mary Magdalene, Marie de Bethany, for Jesus, in the holy legends, in the worship of the Virgin Mary in the Middle Ages, and especially in art. The ecstatic Madonnas in our art galleries cast their fervent regards on Jesus or on the heavens. The expression in Murillo's 'Immaculate Conception' may be interpreted by the highest voluptuous exaltation of love as well as by holy transfiguration. The 'saints' of Correggio regard the Virgin with an amorous ardour which may be celestial, but appears in reality extremely terrestrial and human."[96] Another German authority remarks:-- "I venture to express my conviction that we should rarely err if, in a case of religious melancholy, we assumed the sexual apparatus to be implicated."[97] Dr. Bevan Lewis points out how frequently religious exaltation occurs with women at puberty, and religious melancholia at the period of sexual decline. And Dr. Charles Mercier puts the interchangeability of sexual and religious feelings in the following passage:--
