This Greek word signifies “emotion of the bowels, internal agitation.” Was the word invented by the Greeks to express the vibrations experienced by the nerves, the dilation and shrinking of the intestines, the violent contractions of the heart, the precipitous course of those fiery spirits which mount from the viscera to the brain whenever we are strongly and vividly affected?

Or was the term “enthusiasm,” after painful affection of the bowels, first applied to the contortions of the Pythia, who, on the Delphian tripod, admitted the inspiration of Apollo in a place apparently intended for the receptacle of body rather than of spirit?

What do we understand by enthusiasm? How many shades are there in our affections! Approbation, sensibility, emotion, distress, impulse, passion, transport, insanity, rage, fury. Such are the stages through which the miserable soul of man is liable to pass.

A geometrician attends at the representation of an affecting tragedy. He merely remarks that it is a judicious, well-written performance. A young man who sits next to him is so interested by the performance that he makes no remark at all; a lady sheds tears over it; another young man is so transported by the exhibition that to his great misfortune he goes home determined to compose a tragedy himself. He has caught the disease of enthusiasm.

The centurion or military tribune who considers war simply as a profession by which he is to make his fortune, goes to battle coolly, like a tiler ascending the roof of a house. C?sar wept at seeing the statue of Alexander.

Ovid speaks of love only like one who understood it. Sappho expressed the genuine enthusiasm of the passion, and if it be true that she sacrificed her life to it, her enthusiasm must have advanced to madness.

The spirit of party tends astonishingly to excite enthusiasm; there is no faction that has not its “energumens,” its devoted and possessed partisans. An animated speaker who employs gesture in his addresses, has in his eyes, his voice, his movements. a subtle poison which passes with an arrow’s speed into the ears and hearts of his partial hearers. It was on this ground that Queen Elizabeth forbade any one to preach, during six months, without an express licence under her sign manual, that the peace of her kingdom might be undisturbed.

St. Ignatius, who possessed very warm and susceptible feelings, read the lives of the fathers of the desert after being deeply read in romances. He becomes, in consequence, actuated by a double enthusiasm. He constitutes himself knight to the Virgin Mary, he performed the vigil of arms; he is eager to fight for his lady patroness; he is favored with visions; the virgin appears and recommends to him her son, and she enjoins him to give no other name to his society than that of the “Society of Jesus.”

Ignatius communicates his enthusiasm to another Spaniard of the name of Xavier. Xavier hastens away to the Indies, of the language of which he is utterly ignorant, thence to Japan, without knowing a word of Japanese. That, however, is of no consequence; the flame of his enthusiasm catches the imagination of some young Jesuits, who, at length, make themselves masters of that language. These disciples, after Xavier’s death, entertain not the shadow of a doubt that he performed more miracles than ever the apostles did, and that he resuscitated seven or eight persons at the very least. In short, so epidemic and powerful becomes the enthusiasm that they form in Japan what they denominate a Christendom (une Chrétienté). This Christendom ends in a civil war, in which a hundred thousand persons are slaughtered: the enthusiasm then is at its highest point, fanaticism; and fanaticism has become madness.

The young fakir who fixes his eye on the tip of his nose when saying his prayers, gradually kindles in devotional ardor until he at length believes that if he burdens himself with chains of fifty pounds weight the Supreme Being will be obliged and grateful to him. He goes to sleep with an imagination totally absorbed by Brahma, and is sure to have a sight of him in a dream. Occasionally even in the intermediate state between sleeping and waking, sparks radiate from his eyes; he beholds Brahma resplendent with light; he falls into ecstasies, and the disease frequently becomes incurable.............
