Direct observation of man reveals at once the fact that a very considerable proportion of his beliefs are non-rational to a degree which is immediately obvious without any special examination, and with {36} no special resources other than common knowledge. If we examine the mental furniture of the average man, we shall find it made up of a vast number of judgments of a very precise kind upon subjects of very great variety, complexity, and difficulty. He will have fairly settled views upon the origin and nature of the universe, and upon what he will probably call its meaning; he will have conclusions as to what is to happen to him at death and after, as to what is and what should be the basis of conduct. He will know how the country should be governed, and why it is going to the dogs, why this piece of legislation is good and that bad. He will have strong views upon military and naval strategy, the principles of taxation, the use of alcohol and vaccination, the treatment of influenza, the prevention of hydrophobia, upon municipal trading, the teaching of Greek, upon what is permissible in art, satisfactory in literature, and hopeful in science.

The bulk of such opinions must necessarily be without rational basis, since many of them are concerned with problems admitted by the expert to be still unsolved, while as to the rest it is clear that the training and experience of no average man can qualify him to have any opinion upon them at all. The rational method adequately used would have told him that on the great majority of these questions there could be for him but one attitude—that of suspended judgment.

In view of the considerations that have been discussed above, this wholesale acceptance of non-rational belief must be looked upon as normal. The mechanism by which it is effected demands some examination, since it cannot be denied that the facts conflict noticeably with popularly current views as to the part taken by reason in the formation of opinion.

It is clear at the outset that these beliefs are invariably regarded by the holder as rational, and {37} defended as such, while the position of one who holds contrary views is held to be obviously unreasonable. The religious man accuses the atheist of being shallow and irrational, and is met by a similar reply; to the Conservative, the amazing thing about the Liberal is his incapacity to see reason and accept the only possible solution of public problems. Examination reveals the fact that the differences are not due to the commission of the mere mechanical fallacies of logic, since these are easily avoided, even by the politician, and since there is no reason to suppose that one party in such controversies is less logical than the other. The difference is due rather to the fundamental assumptions of the antagonists being hostile, and these assumptions are derived from herd suggestion; to the Liberal, certain basal conceptions have acquired the quality of instinctive truth, have become “a priori syntheses,” because of the accumulated suggestions to which he has been exposed, and a similar explanation applies to the atheist, the Christian, and the Conservative. Each, it is important to remember, finds in consequence the rationality of his position flawless, and is quite incapable of detecting in it the fallacies which are obvious to his opponent, to whom that particular series of assumptions has not been rendered acceptable by herd suggestion.

To continue further the analysis of non-rational opinion, it should be observed that the mind rarely leaves uncriticized the assumptions which are forced on it by herd suggestion, the tendency being for it to find more or less elaborately rationalized justifications of them. This is in accordance with the enormously exaggerated weight which is always ascribed to reason in the formation of opinion and conduct, as is very well seen, for example, in the explanation of the existence of altruism as being due to man seeing that it “pays.” {38}

It is of cardinal importance to recognize that in this process of the rationalization of instinctive belief, it is the belief which is the primary thing, while the explanation, although masquerading as the cause of the belief, as the chain of rational evidence on which the belief is founded, is entirely secondary, and but for the belief would never have been thought of. Such rationalizations are often, in the case of intelligent people, of extreme ingenuity, and may be very misleading unless the true instinctive basis of the given opinion or action is thoroughly understood.

This mechanism enables the English lady, who, to escape the stigma of having normal feet, subjects them to a formidable degree of lateral compression, to be aware of no logical inconsequence when she subscribes to missions to teach the Chinese lady how absurd it is to compress her feet longitudinally; it enables the European lady who wears rings in her ears to smile at the barbarism of the coloured lady who wears her rings in her nose; it enables the Englishman who is amused by the African chieftain’s regard for the top hat as an essential piece of the furniture of state to ignore the identity of his own behaviour when he goes to church beneath the same tremendous ensign.

The objectivist finds himself compelled to regard these and similar correspondences between the behaviour of civilized and barbarous man as no mere interesting coincidences, but as phenomena actually and in the grossest way identical, but such an attitude is possible only when the mechanism is understood by which rationalization of these customs is effected.

The process of rationalization which has just been illustrated by some of its simpler varieties is best seen on the largest scale, and in the most elaborate form, in the pseudosciences of political economy and ethics. Both of these are occupied in deriving {39} from eternal principles justifications for masses of non-rational belief which are assumed to be permanent merely because they exist. Hence the notorious acrobatic feats of both in the face of any considerable variation in herd belief.

It would seem that the obstacles to rational thought which have been pointed out in the foregoing discussion have received much less attention than should have been directed towards them. To maintain an attitude of mind which could be called scientific in any complete sense, it is of cardinal importance to recognize that belief of affirmations sanctioned by the herd is a normal mechanism of the human mind, and goes on however much such affirmations may be opposed by evidence, that reason cannot enforce belief against herd suggestion, and finally that totally false opinions may appear to the holder of them to possess all the characters of rationally verifiable truth, and may be justified by secondary processes of rationalization which it may be impossible directly to combat by argument.
