The encouragement of recognized lines of special thought is by no means sufficient. It is equally important that we have the utmost freedom of proposal and discussion for projects originating in unforeseen and unaccredited quarters. The specialist, whether lawyer, economist, biologist, business man, minister, socialist, anarchist, or what-not, is, after all, likely to be an expression of what has already been worked out, an organ of the institution, not confronting the new situation in the naïve and unbiased manner which may give value to the views of people of inferior training.

And, moreover, fruitful originality may come quite as much from urgent contact with the situation as from more general knowledge. Workmen in the shop have suggested innumerable improvements which the designer in his office would never have thought of; and practicable ideas of economic and social betterment originate largely with those who have most reason to feel the wrong of the actual condition of things. At any rate their point of view is essential to the formulation of a good plan, and should have every facility to impress itself upon the general process of thought.

The question of free speech is surrounded by a kind of illusion, as a result of which we think of it as a matter that was important in the past, and still is, perhaps, in other circles of society, but is not so in our own environment. We are confident, if we think of the matter at all, that we are not interfering with free speech, nor are any of those other liberal-minded people our friends and associates.

But this is what people have always believed. We know how humane and broad-minded the Emperor Marcus Aurelius was, and also how he regretted the turbulence of the Christians and the severity he felt compelled to use toward them—the same occurrences which have come down to us in the Christian tradition as martyrdoms. Torquemada, of the Spanish Inquisition, was a humane and liberal-minded man in his own view and that of his associates, and so were the burners of witches, the German officials in Belgium, and indeed nearly all of those we look upon as persecutors.

The plain truth is that we are all engaged with more or less energy in endeavoring to force upon others those modes of thought and behavior which we, as a result of our habit and environment, have come to look upon as decent and necessary. This is all that Torquemada did, and we, as I say, are doing no less. The main difference is that we have become more humane in our methods of suppression, and even somewhat aware, vaguely and intermittently, of the illusion of which I speak, so that we are inclined to admit, especially in matters remote from ourselves, the importance of insisting upon freedom of speech.

It is indeed a matter for eternal vigilance and courage, not only in resisting the unconscious encroachments of others but in keeping our own minds open and tolerant. The question is a very real one in American universities, where ideas that shock prevalent habits of thought can hardly be advocated without resisting social and academic pressure, and, perhaps, endangering one’s position, or advancement that might otherwise be expected. This was true thirty or forty years ago as regards the doctrine of evolution; it was true quite recently as regards socialism; it is true now of other social and economic heresies, such as birth-control, pacifism, or what-not, that in time may become entirely respectable.

The need of tolerance has been greatly increased by the rise of a social system which aims to be intelligent, recognizes change as rational, and seeks to guide it by discussion. Under an older régime, as in the Middle Ages, the prevalent doctrine was that there could be but one right way of thinking and that others must be suppressed. And in a society not organized for discussion there was more truth in this than the modern reader of history is apt to admit. A thousand years ago freedom of religious teaching, for example, would probably have resulted in doctrinal and moral anarchy. Innumerable conflicting sects would have sprung up, and there was no general organization of thought vigorous enough to keep them within limits or maintain a voluntary unity. In this, as in many other fields, we can dispense with a compulsory discipline because we have developed one which is spontaneous: formerly, if there was to be a moral whole it had to be authoritative. Even now this is more or less true of unenlightened populations, and it is only along with a campaign for enlightenment that we can safely demand freedom of speech.

It is essential to the intelligent conduct of society that radical groups, however small and unpopular, should develop and express their views. Their proposals do good by forcing the discussion of principles and so leading to an illumination otherwise impossible. The large and moderate parties have a conforming tendency and usually differ but little in principles, if indeed they are conscious of these at all. But the radical programme is a challenge to thought, and can hardly fail to be educative. For some time past the Socialists have been of the utmost service in this way, and round their searching theories of human betterment discussion has largely centred. I have often been impressed by their value as a factor in clarifying the minds of college students. Such theories are like the occupation of an advanced post by a detachment of an army: they push forward the line of battle even if the position occupied does not, in the long run, prove tenable. We easily overlook the fact that an honest project is seldom wholly wrong, and that even if it is there may be profit in discussing it.

The value of partial isolation as a factor in social intelligence is not often recognized in a democracy, where, under the sway of the brotherhood idea, we commonly assume that we cannot see too much of one another. But if we are to have a rich organization of thought, including many types of men, each good of its kind, we must have a corresponding diversity of environments in which these types of men may get their nurture. The culture of individuality, the need of which we are beginning to recognize, cannot go far except as we also foster distinctive groups. We need many kinds of family, of school, of church, of community, of occupational and culture associations, each with a tradition and spirit of its own.

There is much to be said in favor of our schools and universities entering heartily into the lives of the communities that surround them; but if the communities are of a spirit hostile or indifferent to culture they may, and partly do, submerge the latter in their own barbarism. The democratization of higher traditions must be on a plane of militant leadership, not of concession, or it is pernicious. Better a real culture, though in monasteries, than a general vulgarization.
