"In New South Wales," says Westermarck, "the first-born of every lubra used to be eaten by the tribe 'as part of a religious ceremony.' In the realm of Khai-muh, in China, according to a native account, it was customary to kill and devour the eldest son alive. Among certain tribes in British Columbia the first child is often sacrificed to the sun. The Indians of Florida, according to Le Moyne de Morgues, sacrificed the first-born son to the chief....'"[4]

There are pages and pages of such instances.

There is nothing analogous to these practices among ourselves. When the first-born in Florida was told that his king and country needed him, this was a mere mistake, and with us mistakes of this kind do not occur. But it is interesting to inquire how these superstitions died out, in such cases, for example, as that of Khai-muh, where foreign compulsion is improbable. We may surmise that some parents, under the selfish influence of parental affection, were led to doubt whether the sun would really be angry if the eldest child were allowed to live. Such rationalism would be regarded as very dangerous, since it was calculated to damage the harvest. For generations the opinion would be cherished in secret by a handful of cranks, who would not be able to act upon it. At last, by concealment or flight, a few parents would save their children from the sacrifice. Such parents would be regarded as lacking all public spirit, and as willing to endanger the community for their private pleasure. But gradually it would appear that the state remained intact, and the crops were no worse than in former years. Then, by a fiction, a child would be deemed to have been sacrificed if it was solemnly dedicated to agriculture or some other work of national importance chosen by the chief. It would be many generations before the child would be allowed to choose its own occupation after it had grown old enough to know its own tastes and capacities. And during all those generations, children would be reminded that only an act of grace had allowed them to live at all, and would exist under the shadow of a purely imaginary duty to the state.

The position of those parents who first disbelieved in the utility of infant sacrifice illustrates all the difficulties which arise in connection with the adjustment of individual freedom to public control. The authorities, believing the sacrifice necessary for the good of the community, were bound to insist upon it; the parents, believing it useless, were equally bound to do everything in their power toward saving the child. How ought both parties to act in such a case?

The duty of the skeptical parent is plain: to save the child by any possible means, to preach the uselessness of the sacrifice in season and out of season, and to endure patiently whatever penalty the law may indict for evasion. But the duty of the authorities is far less clear. So long as they remain firmly persuaded that the universal sacrifice of the first-born is indispensable, they are bound to persecute those who seek to undermine this belief. But they will, if they are conscientious, very carefully examine the arguments of opponents, and be willing in advance to admit that these arguments may be sound. They will carefully search their own hearts to see whether hatred of children or pleasure in cruelty has anything to do with their belief. They will remember that in the past history of Khai-muh there are innumerable instances of beliefs, now known to be false, on account of which those who disagreed with the prevalent view were put to death. Finally they will reflect that, though errors which are traditional are often wide-spread, new beliefs seldom win acceptance unless they are nearer to the truth than what they replace; and they will conclude that a new belief is probably either an advance, or so unlikely to become common as to be innocuous. All these considerations will make them hesitate before they resort to punishment.

II

The study of past times and uncivilized races makes it clear beyond question that the customary beliefs of tribes or nations are almost invariably false. It is difficult to divest ourselves completely of the customary beliefs of our own age and nation, but it is not very difficult to achieve a certain degree of doubt in regard to them. The Inquisitor who burnt men at the stake was acting with true humanity if all his beliefs were correct; but if they were in error at any point, he was inflicting a wholly unnecessary cruelty. A good working maxim in such matters is this: Do not trust customary beliefs so far as to perform actions which must be disastrous unless the beliefs in question are wholly true. The world would be utterly bad, in the opinion of the average Englishman, unless he could say "Britannia rules the waves"; in the opinion of the average German, unless he could say "Deutschland über alles." For the sake of these beliefs, they are willing to destroy European civilization. If the beliefs should happen to be false, their action is regrettable.

One fact which emerges from these considerations is that no obstacle should be placed in the way of thought and its expression, nor yet in the way of statements of fact. This was formerly common ground among liberal thinkers, though it was never quite realized in the practice of civilized countries. But it has recently become, throughout Europe, a dangerous paradox, on account of which men suffer imprisonment or starvation. For this reason it has again become worth stating. The grounds for it are so evident that I should be ashamed to repeat them if they were not universally ignored. But in the actual world it is very necessary to repeat them.

To attain complete truth is not given to mortals, but to advance toward it by successive steps is not impossible. On any matter of general interest, there is usually, in any given community at any given time, a received opinion, which is accepted as a matter of course by all who give no special thought to the matter. Any questioning of the received opinion rouses hostility, for a number of reasons.
