Many think that in the cases recorded we have but the symptoms of well-known diseases, which, from their exceptionally painful character, involving loss of reason, involuntary or convulsive motions, and other abnormal phenomena, the imaginative and unscientific Easterns attributed, as the easiest mode of accounting for them, to a foreign power taking possession of the body and mind of the man. They say there is no occasion whatever to resort to an explanation involving an agency of which we know nothing from any experience of our own; that, as our Lord did not come to rectify men's psychological or physiological theories, he adopted the mode of speech common amongst them, but cast out the evil spirits simply by healing the diseases attributed to their influences. There seems to me nothing unchristian in this interpretation. All diseases that trouble humanity may well be regarded as inroads of the evil powers upon the palaces and temples of God, where only the Holy Spirit has a right to dwell; and to cast out such, is a marvel altogether as great as to expel the intruding forces to which the Jews attributed some of them. Certainly also our Lord must have used multitudes of human expressions which did not more than adumbrate his own knowledge. And yet I cannot admit that the solution meets all the appearances of the difficulty. I say _appearances_, because I could not be dogmatic here if I would. I know too little, understand too little, to dare give such an opinion as possesses even the authority of personal conviction. All I have to say on the subject must therefore come to little. Perhaps if the marvellous, as such, were to me more difficult of belief, anything I might have to say on the side of it would have greater weight. But to me the marvellous is not therefore incredible, always provided that in itself the marvellous thing appears worthy. I have no difficulty in receiving the old Jewish belief concerning possession; and I think it better explains the phenomena recorded than the growing modern opinion; while the action of matter upon mind may well be regarded as involving greater mystery than the action of one spiritual nature upon another. That a man should rave in madness because some little cell or two in the grey matter of his brain is out of order, is surely no more within the compass of man's understanding than the supposition that an evil spirit, getting close to the fountain of a man's physical life, should disturb all the goings on of that life, even to the production of the most appalling moral phenomena. In either case it is not the man himself who originates the resulting actions, but an external power operating on the man.
