Freedom of thought and freedom of speech stand to each other as the two halves of a pair of scissors. Without freedom of speech freedom of thought is robbed of the better part of its utility, even if its existence is not threatened. The one reacts on the other. As thought provides the material for speech, so, in turn, it deteriorates when it is denied expression. Speech is, in fact, one of the great factors in human progress. It is that which enables one generation to hand on to another the discoveries made, the inventions produced, the thoughts achieved, and so gives a degree of fixity to the progress attained. For progress, while expressed through the individual, is achieved by the race. Individually, the man of to-day is not strikingly superior in form or capacity to the man of five or ten thousand years ago. But he knows more, can achieve more, and is in that sense stronger than was his ancestors. He is the heir of the ages, not as a figure of speech, but as the most sober of facts. He inherits what previous generations have acquired; the schoolboy of to-day starts with a capital of inherited knowledge that would have been an outfit for a philosopher a few thousand years ago.

It is this that makes speech of so great importance to the fact of progress. Without speech, written or verbal, it would be impossible to conserve the products of human achievement. Each generation would have to start where its predecessor commenced, and it would finish at about the same point. It would be the fable of Sisyphus illustrated in the passing of each generation of human beings.

But speech implies communication. There is not very much pleasure in speaking to oneself. Even the man who apologised for the practice on the ground that he liked to address a sensible assembly would soon grow tired of so restricted an audience. The function of speech is to transmit ideas, and it follows, therefore, that every embargo on the free exchange of ideas, every obstacle to complete freedom of speech, is a direct threat to the well-being of civilisation. As Milton could say that a good book "is the precious life-blood of a master spirit, embalmed and treasured up to a life beyond life," and that "he who destroys a good book kills reason itself," so we may say that he who strikes at freedom of thought and speech is aiming a blow at the very heart of human betterment.

In theory, the truth of what has been said would be readily admitted, but in practice it has met, and still meets, with a vigorous opposition. Governments have exhausted their powers to prevent freedom of intercourse between peoples, and every Church and chapel has used its best endeavours to the same end. Even to-day, when all are ready to pay lip-homage to freedom of thought, the obstacles in the way of a genuine freedom are still very great. Under the best possible conditions there will probably always be some coercion of opinion, if only of that unconscious kind which society as a whole exerts upon its individual members. But to this we have to add the coercion that is consciously exerted to secure the formation of particular opinions, and which has the dual effect of inducing dissimulation in some and impotency in others. Quite ignorantly parents commence the work when they force upon children their own views of religion and inculcate an exaggerated respect for authority. They create an initial bias that is in only too many cases fatal to real independence of thought. Social pressure continues what a mistaken early training has commenced. When opinions are made the test of "good form," and one's social standing partly determined by the kind of opinions that one holds, there is developed on the one side hypocrisy, and on the other, because certain opinions are banned, thought in general is unhealthily freed from the sobering influence of enlightened criticism.[11]

To-day the legal prohibition of religious dissent is practically ineffective, and is certainly far less demoralizing than the pressure that is exerted socially and unofficially. In all probability this has always been the case. For legal persecution must be open. Part of its purpose is publicity, and that in itself is apt to rouse hostility. Against open, legal persecution a man will make a stand, or if he gives way to the force arrayed against him may do so with no feeling of personal degradation. But the conformity that is secured by a threat of social boycott, the freedom of speech that is prevented by choking the avenues of intellectual intercourse, is far more deadly in its consequences, and far more demoralizing in its influence on character. To give way, as thousands do, not to the open application of force, which carries no greater personal reflection than does the soldier's surrender to superior numbers, but to the dread of financial loss, to the fear of losing a social status, that one may inwardly despise even while in the act of securing it, or from fear of offending those whom we may feel are not worthy of our respect, these are the things that cannot be done without eating into one's sense of self-respect, and inflicting upon one's character an irreparable injury.

On this matter more will be said later. For the present I am concerned with the sense in which we are using the word "Freethought." Fortunately, little time need be wasted in discussing the once popular retort to the Freethinker that if the principle of determinism be accepted "free" thought is impossible. It is surprising that such an argument should ever have secured a vogue, and is only now interesting as an indication of the mentality of the defender of orthodox religion. Certainly no one who properly understands the meaning of the word would use such an argument. At best it is taking a word from sociology, a sphere in which the meaning is quite clear and intelligible, and applying it in the region of physical science where it has not, and is not intended to have, any meaning at all. In physical science a thing is what it does, and the business of science is to note the doings of forces and masses, their actions and reactions, and express them in terms of natural "law." From the point of view of physical science a thing is neither free nor unfree, and to discuss natural happenings in terms of freedom or bondage is equal to discussing smell in terms of sight or colour in terms of smell. But applied in a legitimate way the word "free" is not only justifiable, it is indispensible. The confusion arises when we take a word from a department in which its meaning is quite clear and apply it in a region where it has no application whatever.

Applied to opinion "Free" has the same origin and the same application as the expressions "a free man," or a "free State," or "a free people." Taking either of these expressions it is plain that they could have originated only in a state of affairs where some people are "free," and some are living in a state of bondage or restraint. There is no need to trace the history of this since so much is implied in the word itself. A free State is one in which those belonging to it determine their own laws without being coerced by an outside power. A free man is one who is permitted to act as his own nature prompts. The word "free" implies nothing as to the nature of moral or mental causation, that is a question of a wholly different order. The free man exists over against the one who is not free, the free State over against one that is held in some degree of subjection to another State. There is no other meaning to the word, and that meaning is quite clear and definite.

Now Freethought has a precisely similar significance. It says nothing as to the nature of thought, the origin of thought, or the laws of thought. With none of these questions is it vitally concerned. It simply asserts that there are conditions under which thought is not "free," that is, where it is coerced to a foregone conclusion, and that these conditions are fatal to thought in its higher and more valuable aspects. Freethought is that form of thinking that proceeds along lines of its own determining, rather than along lines that are laid down by authority. In actual practice it is immediately concerned with the expression of opinion rather than with its formation, since no authority can prevent the formation of opinion in any mind that is at all independent in its movements and forms opinions on the basis of observed facts and adequate reasoning. But its chief and primary significance lies in its repudiation of the right of authority to say what form the expression of opinion shall take. And it is also clear that such a term as "Freethought" could only have come into general use and prominence in a society in which the free circulation of opinion was more or less impeded.

It thus becomes specially significant that, merely as a matter of history, the first active manifestation of Freethought should have occurred in connection with a revolt against religious teaching and authority. This was no accident, but was rather a case of necessity. For, in the first place, there is no other subject in which pure authority plays so large a part as it does in religion. All churches and all priesthoods, ancient and modern, fall back upon the principle of pure authority as a final method of enforcing their hold upon the people. That, it may be noted in passing, is one of the chief reasons why in all ages governments have found religion one of the most serviceable agencies in maintaining their sway. Secondly, there seems to have been from the very earliest times a radically different frame of mind in the approach to secular and religious matters. So far as one can see there appears to be, even in primitive societies, no very strong opposition to the free discussion of matters that are of a purely secular nature. Questions of ways and means concerning these are freely debated among savage tribes, and in all discussion differences of opinion must be taken for granted. It is when we approach religious subjects that a difference is seen. Here the main concern is to determine the will of the gods, and all reasoning is thus out of place, if not a positive danger. The only thing is to discover "God's will," and when we have his, or his will given in "sacred" books the embargo on free thinking is complete. This feature continues to the end. We do not even to-day discuss religious matters in the same open spirit in which secular matters are debated. There is a bated breath, a timidity of criticism in discussing religious subjects that does not appear when we are discussing secular topics. With the thoroughly religious man it is solely a question of what God wishes him to do. In religion this affords the only latitude for discussion, and even that disappears largely when the will of God is placed before the people in the shape of "revealed" writings. Fortunately for the world "inspired" writings have never been so clearly penned as to leave no room for doubt as to what they actually meant. Clarity of meaning has never been one of the qualities of divine authorship.

In this connection it is significant that the first form of democratic government of which we have any clear record should have been in freethinking, sceptical Greece. Equally notable is it that in both Rome and Greece the measure of mental toleration was greater than it has ever been in other countries before or since. In Rome to the very end of the Pagan domination there existed no legislation against opinions, as such. The holders of certain opinions might find themselves in uncomfortable positions now and then, but action against them had to rest on some ground other than that which was afterwards known as heresy. There existed no law in the Roman Empire against freedom of opinion, and those who are familiar with Mr. H. C. Lea's classic, History of the Inquisition, will recall his account of the various tactics adopted by the Christian Church to introduce measures that would accustom the public mind to legislation which should establish the principle of persecution for opinion.[12] In the end the Church succeeded in effecting this, and its success was registered in the almost unbelievable degradation of the human intellect which was exhibited in the Christian world for centuries. So complete was this demoralization that more than a thousand years later we find men announcing as a most daring principle a demand for freedom of discussion which in old Greece and Rome was never officially questioned. Christianity not merely killed freedom wherever it established itself, but it came very near killing even the memory of it.

It was, therefore, inevitable that in the western world Freethought should come into prominence in relation to the Christian religion and its claims. In the Christian Church there existed an organization which not alone worked with the avowed intention of determining what men should think, but finally proceeded to what was, perhaps, the logical conclusion, to say what they should not think. No greater tyranny than the Christian Church has ever existed. And this applies, not to the Roman Church alone, but to every Church within the limit of its opportunities. In the name and in the interests of religion the Christian Church took some of the worst passions of men and consecrated them. The killing of heretics became one of the most solemn duties and it was urged upon secular rulers as such. The greatest instrument of oppression ever formed, the Inquisition, was fashioned for no other purpose than to root out opinions that were obnoxious to the Church. It would have been bad enough had the attempts of the Church to control opinion been limited to religion. But that was not the case. It aimed at taking under its control all sorts of teaching on all sorts of subjects. Nothing would have surprised an inhabitant of ancient Rome more, could he have revisited the earth some dozen centuries after the establishment of Christianity, than to have found men being punished for criticising doctrines that were in his day openly laughed at. And nothing could have given an ancient Athenian greater cause for wonder than to have found men being imprisoned and burned for teaching cosmical theories that were being debated in the schools of Athens two thousand years before. Well might they have wondered what had happened to the world, and well might they have come to the conclusion that it had been overtaken by an attack of universal insanity. And the explanation would not have been so very wide of the truth.

In this matter of suppression of freedom of thinking there was little to choose between the Churches. Each aimed at controlling the thought of mankind, each was equally intolerant of any variation from the set line, and each employed the same weapon of coercion so far as circumstances permitted. At most the Protestant Churches substituted a dead book for a living Church, and in the end it may be questioned, when all allowance is made for the changed circumstances in which Protestantism operated, whether the rule of the new Church was not more disastrous than the older one. It had certainly less excuse for its intolerance. The Roman Catholic Church might urge that it never claimed to stand for freedom of opinion, and whatever its sins it was so far free from the offence of hypocrisy. But the Protestant Churches could set up no such plea; they professed to stand on freedom of conscience. And they thus added the quality of inconsistency and hypocrisy to an offence that was already grave enough in itself. But whatever opinion one may have on that point, it is certain that in practice the Protestant leaders were as opposed to freedom of thought as were the Roman Catholics. And Protestant bigotry left a mark on European history that deserves special recognition. For the first time it made the profession of Christianity a definite part of the law of the secular State.[13] Hitherto there had been no law in any of the European States which made a profession of Christianity necessary. There had been plenty of persecutions of non-Christians, and the consequences of a rejection of Christianity, if one lived in a Christian State, were serious enough. But when the secular State punished the heretic it was a manifestation of good will towards the Church and not the expression of a legal enactment. It was the direct influence of the Church on the State. Church and State were legally distinct during the mediÆval period, however closely they may have been allied in practice. With the arrival of Protestantism and the backing of the reformed religion given by certain of the Princes, the machinery of intolerance, so to speak, was taken over by the State and became one of its functions. It became as much the duty of the secular officials to extirpate heresy, to secure uniformity of religious belief as it was to the interest of the Church to see that it was destroyed. Up to that time it was the aim of the Church to make the State one of its departments. It had never legally succeeded in doing this, but it was not for the Roman Church to sink to the subordinate position of becoming a department of the State. It was left for Protestantism to make the Church a branch of the State and to give religious bigotry the full sanction of secular law. Neither with Catholic nor Protestant could there be, therefore, any relaxation in the opposition offered to independent thinking. That still remained the cardinal offence to the religious mind. In the name of religion Protestants opposed the physics of Newton as bitterly as Catholics opposed the physics of Galileo. The geology of Hutton and Lyell, the chemistry of Boyle and Dalton, the biology of Von Baer, Lamarck and Darwin, with almost any other branch of science that one cares to select, tell the same tale. And when the desire for reform took a social turn there was the same influence to be fought. For while the Roman Catholic laid the chief insistence on obedience to the Church, the Protestant laid as strong insistence on obedience to the State, and made disobedience to its orders a matter of almost religious revolt. The whole force of religion was thus used to induce contentment with the existing order, instead of to the creation of an intelligent discontent which would lead to continuous improvement. In view of these circumstances it is not surprising that the word "Freethought" should have lost in actual use its more general significance of a denial of the place of mere authority in matters of opinion, and have acquired a more definite and precise connotation. It could not, of course, lose its general meaning, but it gained a special application and became properly associated with a definitely anti-theological attitude. The growth in this direction was gradual but inevitable. When the term first came into general use, about the end of the seventeenth century, it was mainly used with reference to those deists who were then attacking Christianity. In that sense it continued to be used for some time. But as Deism lost ground, thanks partly to the Christian attack, the clear and logical issue between Theism and Atheism became apparent, with the result that the definite anti-religious character of "Freethought" became firmly established. And to-day it is mere affectation or timidity to pretend that the word has any other vital significance. To say that a man is a Freethinker is to give, to ninety-nine people out of a hundred, the impression that he is anti-religious. And in this direction the popular sense of the word discloses what has been its important historic function. Historically, the chief stronghold of mere authority has been religion. In science and in sociology, as well as in connection with supernaturalism proper, every movement in the direction of the free exercise of the intellect has met with the unceasing opposition of religion. That has always been at once the symbol and the instrument of oppression. To attack religion has been to attack the enemy in his capital. All else has been matter of outpost skirmishing.

I have apparently gone a long way round to get at the meaning of the word "Freethought," but it was necessary. For it is of very little use, in the case of an important word that has stood and stands for the name of a movement, to go to a dictionary, or to appeal to etymology. The latter has often a mere antiquarian interest, and the former merely registers current meanings, it does not make them. The use of a word must ultimately be determined by the ideas it conveys to those who hear it. And from what has been said the meaning of this particular word should be fairly clear. While standing historically for a reasoned protest against the imposition of opinion by authority, and, negatively, against such artificial conditions as prevent the free circulation of opinion, it to-day stands actually for a definitely anti-religious mental attitude. And this is what one would naturally expect. Protests, after all, are protests against something in the concrete, even though they may embody the affirmation of an abstract principle. And nowadays the principle of pure authority has so few defenders that it would be sheer waste of time, unless the protest embodied a definite attitude with regard to specific questions. We may, then, put it that to us "Freethought" stands for a reasoned and definite opposition to all forms of supernaturalism, it claims the right to subject all religious beliefs to the test of reason, and further claims that when so tested they break down hopelessly. It is from this point of view that these pages are written, and the warranty for so defining it should be apparent from what has been said in this and the preceding chapter.
