The memory that an oath or vow has been made will nerve one to abstinences and efforts otherwise impossible; witness the "pledge" in the history of the temperance movement. A mere promise to his sweetheart will clean up a youth's life all over—at any rate for time. For such effects an educated susceptibility is required. The idea of one's "honor," for example, unlocks energy only in those of us who have had the education of a "gentleman," so called.

That delightful being, Prince Pueckler-Muskau, writes to his wife from England that he has invented "a sort of artificial resolution respecting things that are difficult of performance. My device," he continues, "is this: I give my word of honor most solemnly to myself to do or to leave undone this or that. I am of course extremely cautious in the use of this expedient, but when once the word is given, even though I afterwards think I have been precipitate or mistaken, I hold it to be perfectly irrevocable, whatever inconveniences I foresee likely to result. If I were capable of breaking my word after such mature consideration, I should lose all respect for myself,—and what man of sense would not prefer death to such an alternative? . . . When the mysterious formula is pronounced, no alteration in my own view, nothing short of physical impossibilities, must, for the welfare of my soul, alter my will. . . . I find something very satisfactory in the thought that man has the power of framing such props and weapons out of the most trivial materials, indeed out of nothing, merely by the force of his will, which thereby truly deserves the name of omnipotent." [3]

Conversions, whether they be political, scientific, philosophic, or religious, form another way in which bound energies are let loose. They unify us, and put a stop to ancient mental interferences. The result is freedom, and often a great enlargement of power. A belief that thus settles upon an individual always acts as a challenge to his will. But, for the particular challenge to operate, he must be the right challeng_ee_. In religious conversions we have so fine an adjustment that the idea may be in the mind of the challengee for years before it exerts effects; and why it should do so then is often so far from obvious that the event is taken for a miracle of grace, and not a natural occurrence. Whatever it is, it may be a highwater mark of energy, in which "noes," once impossible, are easy, and in which a new range of "yeses" gains the right of way.

We are just now witnessing a very copious unlocking of energies by ideas in the persons of those converts to "New Thought," "Christian Science," "Metaphysical Healing," or other forms of spiritual philosophy, who are so numerous among us to-day. The ideas here are healthy-minded and optimistic; and it is quite obvious that a wave of religious activity, analogous in some respects to the spread of early Christianity, Buddhism, and Mohammedanism, is passing over our American world. The common feature of these optimistic faiths is that they all tend to the suppression of what Mr. Horace Fletcher calls "fearthought." Fearthought he defines as the "self-suggestion of inferiority"; so that one may say that these systems all operate by the suggestion of power. And the power, small or great, comes in various shapes to the individual,—power, as he will tell you, not to "mind" things that used to vex him, power to concentrate his mind, good cheer, good temper—in short, to put it mildly, a firmer, more elastic moral tone.

The most genuinely saintly person I have ever known is a friend of mine now suffering from cancer of the breast—I hope that she may pardon my citing her here as an example of what ideas can do. Her ideas have kept her a practically well woman for months after she should have given up and gone to bed. They have annulled all pain and weakness and given her a cheerful active life, unusually beneficent to others to whom she has afforded help. Her doctors, acquiescing in results they could not understand, have had the good sense to let her go her own way.

How far the mind-cure movement is destined to extend its influence, or what intellectual modifications it may yet undergo, no one can foretell. It is essentially a religious movement, and to academically nurtured minds its utterances are tasteless and often grotesque enough. It also incurs the natural enmity of medical politicians, and of the whole trades-union wing of that profession. But no unprejudiced observer can fail to recognize its importance as a social phenomenon to-day, and the higher medical minds are already trying to interpret it fairly, and make its power available for their own therapeutic ends.

Dr. Thomas Hyslop, of the great West Riding Asylum in England, said last year to the British Medical Association that the best sleep-producing agent which his practice had revealed to him, was prayer. I say this, he added (I am sorry here that I must quote from memory), purely as a medical man. The exercise of prayer, in those who habitually exert it, must be regarded by us doctors as the most adequate and normal of all the pacifiers of the mind and calmers of the nerves.

But in few of us are functions not tied up by the exercise of other functions. Relatively few medical men and scientific men, I fancy, can pray. Few can carry on any living commerce with "God." Yet many of us are well aware of how much freer and abler our lives would be, were such important forms of energizing not sealed up by the critical atmosphere in which we have been reared. There are in every one potential forms of activity that actually are shunted out from use. Part of the imperfect vitality under which we labor can thus be easily explained. One part of our mind dams up—even damns up!—the other parts.

Conscience makes cowards of us all. Social conventions prevent us from telling the truth after the fashion of the heroes and heroines of Bernard Shaw. We all know persons who are models of excellence, but who belong to the extreme philistine type of mind. So deadly is their intellectual respectability that we can't converse about certain subjects at all, can't let our minds play over them, can't even mention them in their presence. I have numbered among my dearest friends persons thus inhibited intellectually, with whom I would gladly have been able to talk freely about certain interests of mine, certain authors, say, as Bernard Shaw, Chesterton, Edward Carpenter, H. G. Wells, but it would n't do, it made them too uncomfortable, they would n't play, I had to be silent. An intellect thus tied down by literality and decorum makes on one the same sort of an impression that an able-bodied man would who should habituate himself to do his work with only one of his fingers, locking up the rest of his organism and leaving it unused.

I trust that by this time I have said enough to convince the reader both of the truth and of the importance of my thesis. The two questions, first, that of the possible extent of our powers; and, second, that of the various avenues of approach to them, the various keys for unlocking them in diverse individuals, dominate the whole problem of individual and national education. We need a topography of the limits of human power, similar to the chart which oculists use of the field of human vision. We need also a study of the various types of human being with reference to the different ways in which their energy-reserves may be appealed to and set loose. Biographies and individual experiences of every kind may be drawn upon for evidence here.[4]
