If we ask ourselves what is the matter with Aristotle's argument, we find that he has begun by erecting a great barrier between himself and the facts. When he had said that those who are slaves are by nature intended to be slaves, he at one stroke excluded the fatal question whether those particular men who happened to be slaves were the particular men intended by nature to be slaves. For that question would have tainted each case of slavery with doubt. And since the fact of being a slave was not evidence that a man was destined to be one, no certain test would have remained. Aristotle, therefore, excluded entirely that destructive doubt. Those who are slaves are intended to be slaves. Each slave holder was to look upon his chattels as natural slaves. When his eye had been trained to see them that way, he was to note as confirmation of their servile character the fact that they performed servile work, that they were competent to do servile work, and that they had the muscles to do servile work.

This is the perfect stereotype. Its hallmark is that it precedes the use of reason; is a form of perception, imposes a certain character on the data of our senses before the data reach the intelligence. The stereotype is like the lavender window-panes on Beacon Street, like the door-keeper at a costume ball who judges whether the guest has an appropriate masquerade. There is nothing so obdurate to education or to criticism as the stereotype. It stamps itself upon the evidence in the very act of securing the evidence. That is why the accounts of returning travellers are often an interesting tale of what the traveller carried abroad with him on his trip. If he carried chiefly his appetite, a zeal for tiled bathrooms, a conviction that the Pullman car is the acme of human comfort, and a belief that it is proper to tip waiters, taxicab drivers, and barbers, but under no circumstances station agents and ushers, then his Odyssey will be replete with good meals and bad meals, bathing adventures, compartment-train escapades, and voracious demands for money. Or if he is a more serious soul he may while on tour have found himself at celebrated spots. Having touched base, and cast one furtive glance at the monument, he buried his head in Baedeker, read every word through, and moved on to the next celebrated spot; and thus returned with a compact and orderly impression of Europe, rated one star, or two.

In some measure, stimuli from the outside, especially when they are printed or spoken words, evoke some part of a system of stereotypes, so that the actual sensation and the preconception occupy consciousness at the same time. The two are blended, much as if we looked at red through blue glasses and saw green. If what we are looking at corresponds successfully with what we anticipated, the stereotype is reinforced for the future, as it is in a man who knows in advance that the Japanese are cunning and has the bad luck to run across two dishonest Japanese.

If the experience contradicts the stereotype, one of two things happens. If the man is no longer plastic, or if some powerful interest makes it highly inconvenient to rearrange his stereotypes, he pooh- poohs the contradiction as an exception that proves the rule, discredits the witness, finds a flaw somewhere, and manages to forget it. But if he is still curious and open-minded, the novelty is taken into the picture, and allowed to modify it. Sometimes, if the incident is striking enough, and if he has felt a general discomfort with his established scheme, he may be shaken to such an extent as to distrust all accepted ways of looking at life, and to expect that normally a thing will not be what it is generally supposed to be. In the extreme case, especially if he is literary, he may develop a passion for inverting the moral canon by making Judas, Benedict Arnold, or Caesar Borgia the hero of his tale.

The role played by the stereotype can be seen in the German tales about Belgian snipers. Those tales curiously enough were first refuted by an organization of German Catholic priests known as Pax. [Footnote: Fernand van Langenhove, The Growth of a Legend. The author is a Belgian sociologist.] The existence of atrocity stories is itself not remarkable, nor that the German people gladly believed them. But it is remarkable that a great conservative body of patriotic Germans should have set out as early as August 16, 1914, to contradict a collection of slanders on the enemy, even though such slanders were of the utmost value in soothing the troubled conscience of their fellow countrymen. Why should the Jesuit order in particular have set out to destroy a fiction so important to the fighting morale of Germany?

I quote from M. van Langenhove's account:

"Hardly had the German armies entered Belgium when strange rumors began to circulate. They spread from place to place, they were reproduced by the press, and they soon permeated the whole of Germany. It was said that the Belgian people, instigated by the clergy, had intervened perfidiously in the hostilities; had attacked by surprise isolated detachments; had indicated to the enemy the positions occupied by the troops; that old men, and even children, had been guilty of horrible atrocities upon wounded and defenseless German soldiers, tearing out their eyes and cutting off fingers, nose or ears; that the priests from their pulpits had exhorted the people to commit these crimes, promising them as a reward the kingdom of heaven, and had even taken the lead in this barbarity.

"Public credulity accepted these stories. The highest powers in the state welcomed them without hesitation and endorsed them with their authority…

"In this way public opinion in Germany was disturbed and a lively indignation manifested itself, directed especially against the priests who were held responsible for the barbarities attributed to the Belgians… By a natural diversion the anger to which they were a prey was directed by the Germans against the Catholic clergy generally. Protestants allowed the old religious hatred to be relighted in their minds and delivered themselves to attacks against Catholics. A new Kulturkampf was let loose.
