Hudson, Law of Psychic Phenomena, 129—“The hypnotic subject cannot be controlled so far as to make him do what he knows to be wrong, unless he himself voluntarily assents.” A. S. Hart: “Unless one is willing to be hypnotized, no one can put him under the influence. The more intelligent one is, the more susceptible. Hypnotism requires the subject to do two-thirds of the work, while the instructor does only one-third—that of telling the subject what to do. It is not an inherent influence, nor a gift, but can be learned by any one who can read. It is impossible to compel a person to do wrong while under the influence, for the subject retains a consciousness of the difference between right and wrong.” Höffding, Outlines of Psychology, 330-335—“Some persons have the power of intentionally calling up hallucinations; but it often happens to them as to Goethe’s Zauberlehrling, or apprentice-magician, that the phantoms gain power over them and will not be again dispersed. Goethe’s Fischer—‘Half she drew him down and half he sank’—repeats the duality in the second term; for to sink is to let one’s self sink.” Manton, the Puritan: “A stranger cannot call off a dog from the flock, but the Shepherd can do so with a word; so the Lord can easily rebuke Satan when he finds him most violent.” Spurgeon, the modern Puritan, remarks on the above: “O Lord, when I am worried by my great enemy, call him off, I pray thee! Let me hear a voice saying: ‘_Jehovah rebuke thee, O Satan; even Jehovah that hath chosen Jerusalem rebuke thee!_’ (_Zech. 3:2)_. By thine election of me, rebuke him, I pray thee, and deliver me from ‘_the power of the dog_’! (_Ps. 22:20)_.” Secondly,—their power is limited, both in time and in extent, by the permissive will of God. Evil spirits are neither omnipotent, omniscient, nor omnipresent. We are to attribute disease and natural calamity to their agency, only when this is matter of special revelation. Opposed to God as evil spirits are, God compels them to serve his purposes. Their power for harm lasts but for a season, and ultimate judgment and punishment will vindicate God’s permission of their evil agency. _1 Cor. 10:13_—“_God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation make also the way of escape, that you may be able to endure it_”; _Jude 6_—“_angels which kept not their own beginning, but left their proper habitation, he hath kept in everlasting bonds under darkness unto the judgment of the great day._”
