While a collector of Japanese prints was showing me his treasures we discussed Oriental psychology.

There is no doubt of it. If I am to make these hasty pages, even in a small way, a "mirror of the Passing World," I must grapple with psychology.

Psychology met me at every turn. Bellboys and Pullman porters who understood the psychology of the travelling public knew that a few ineffective passes with a whiskbroom would make us part with our small change. Restaurant waiters who were masters of psychology knew that showing an interest in the food they served and asking if it was entirely suited to our taste made tips imperative—no matter what our convictions and good resolutions on the subject might be.

There is no doubt of it. "Psychology" is now the master word of the world, and as mankind has at all times groaned under the tyranny of words and phrases the matter must be looked into. We have the historic example of "divine right" which tyrannized over the world for many centuries. But let us deal with those words that have influenced our own lives. First we were made to step lively (itself a modern phrase of much potency) by "the strenuous life." Then by a natural reaction we tried to recuperate with "the simple life" and "the rest cure." After that we had a period when "efficiency" hurried the joy out of life. Then came "propagandas" that were designed to enslave the world to all kinds of far-reaching schemes. Now we are up to the neck in "psychology."

The above instances are recorded merely to show the need of dealing with the question if I am to be right up to the minute. And I know practically nothing about it. Why, oh, why, didn't I read Le Bon more carefully, instead of treating his huge volumes as a new and amusing kind of fiction? Still I can remember a little.

The laws governing mob-psychology have been crystallized in the formula, "affirmation, repetition, authority, contagion." Affirm a thing strongly enough, repeat it often enough, have it thundered forth with authority, and finally a contagion of conviction will sweep the multitude. It might be shown that every leader and master of men from Moses to Lloyd George was a master of mob-psychology—for it is a curious fact that history always lends itself to interpretation by the theory that is popular at any given time. And contemporary life also invariably lends itself to the same treatment. Let us take a humble instance.

The successful promotion of a patent medicine follows exactly the best methods of mob-psychology.

The merits of the nostrum are affirmed strongly in advertisements of all kinds from the daily press to the bill-boards and scenic monstrosities. These affirmations are repeated everywhere and at all times. Then we have authoritative testimonials showing the before and after conditions of men and women eminent in all walks of life. Presently a swift contagion sweeps the crowd and we all begin taking "Pale Pills for Peculiar People" or "Dope Drops for Disgruntled Digestions." And the shrewd promoter of the nostrum acquires a great fortune, goes into society, and, if he lives in a country where titles prevail, buys a title by one of the many devious methods of securing such honors.

Certainly it is clear that humanity is at present prostrate before those who are masters of mob-psychology, either through learning or by instinct.
