Why I am Not a Conservative
1. At a time when most movements that are thought to be progressive advocate further encroachments on individual liberty, those who cherish freedom are likely to expend their energies in opposition. In this they find themselves much of the time on the same side as those who habitually resist change. In matters of current politics today they generally have little choice but to support the conservative parties. But, though the position I have tried to define is also often described as “conservative,” it is very different from that to which this name has been traditionally attached. There is danger in the confused condition which brings the defenders of liberty and the true conservatives together in common opposition to developments which threaten their different ideals equally. It is therefore important to distinguish clearly the position taken here from that which has long been known—perhaps more appropriately—as conservatism.
Conservatism proper is a legitimate, probably necessary, and certainly widespread attitude of opposition to drastic change. It has, since the French Revolution, for a century and a half played an important role in European politics. Until the rise of socialism its opposite was liberalism. There is nothing corresponding to this conflict in the history of the United States, because what in Europe was called “liberalism” was here the common tradition on which the American polity had been built: thus the defender of the American tradition was a liberal in the European sense. This already existing confusion was made worse by the recent attempt to transplant to America the European type of conservatism, which, being alien to the American tradition, has acquired a somewhat odd character. And some time before this, American radicals and socialists began calling themselves “liberals.” I will nevertheless continue for the moment to describe as liberal the position which I hold and which I believe differs as much from true conservatism as from socialism. Let me say at once, however, that I do so with increasing misgivings, and I shall later have to consider what would be the appropriate name for the party of liberty. The reason for this is not only that the term “liberal” in the United States is the cause of constant misunderstandings today, but also that in Europe the predominant type of rationalistic liberalism has long been one of the pacemakers of socialism.
Let me now state what seems to me the decisive objection to any conservatism which deserves to be called such. It is that by its very nature it cannot offer an alternative to the direction in which we are moving. It may succeed by its resistance to current tendencies in slowing down undesirable developments, but, since it does not indicate another direction, it cannot prevent their continuance. It has, for this reason, invariably been the fate of conservatism to be dragged along a path not of its own choosing. The tug of war between conservatives and progressives can only affect the speed, not the direction, of contemporary developments. But, though there is need for a “brake on the vehicle of progress,” I personally cannot be content with simply helping to apply the brake. What the liberal must ask, first of all, is not how fast or how far we should move, but where we should move. In fact, he differs much more from the collectivist radical of today than does the conservative. While the last generally holds merely a mild and moderate version of the prejudices of his time, the liberal today must more positively oppose some of the basic conceptions which most conservatives share with the socialists.
2. The picture generally given of the relative position of the three parties does more to obscure than to elucidate their true relations. They are usually represented as different positions on a line, with the socialists on the left, the conservatives on the right, and the liberals somewhere in the middle. Nothing could be more misleading. If we want a diagram, it would be more appropriate to arrange them in a triangle with the conservatives occupying one corner, with the socialists pulling toward the second and the liberals toward the third. But, as the socialists have for a long time been able to pull harder, the conservatives have tended to follow the socialist rather than the liberal direction and have adopted at appropriate intervals of time those ideas made respectable by radical propaganda. It has been regularly the conservatives who have compromised with socialism and stolen its thunder. Advocates of the Middle Way with no goal of their own, conservatives have been guided by the belief that the truth must lie somewhere between the extremes—with the result that they have shifted their position every time a more extreme movement appeared on either wing.
The position which can be rightly described as conservative at any time depends, therefore, on the direction of existing tendencies. Since the development during the last decades has been generally in a socialist direction, it may seem that both conservatives and liberals have been mainly intent on retarding that movement. But the main point about liberalism is that it wants to go elsewhere, not to stand still. Though today the contrary impression may sometimes be caused by the fact that there was a time when liberalism was more widely accepted and some of its objectives closer to being achieved, it has never been a backward-looking doctrine. There has never been a time when liberal ideals were fully realized and when liberalism did not look forward to further improvement of institutions. Liberalism is not averse to evolution and change; and where spontaneous change has been smothered by government control, it wants a great deal of change of policy. So far as much of current governmental action is concerned, there is in the present world very little reason for the liberal to wish to preserve things as they are. It would seem to the liberal, indeed, that what is most urgently needed in most parts of the world is a thorough sweeping-away of the obstacles to free growth. This difference between liberalism and conservatism must not be obscured by the fact that in the United States it is still possible to defend individual liberty by defending long-established institutions. To the liberal they are valuable not mainly because they are long established or because they are American but because they correspond to the ideals which he cherishes.
3. Before I consider the main points on which the liberal attitude is sharply opposed to the conservative one, I ought to stress that there is much that the liberal might with advantage have learned from the work of some conservative thinkers. To their loving and reverential study of the value of grown institutions we owe (at least outside the field of economics) some profound insights which are real contributions to our understanding of a free society. However reactionary in politics such figures as Coleridge, Bonald, De Maistre, Justus Möser, or Donoso Cortès may have been, they did show an understanding of the meaning of spontaneously grown institutions such as language, law, morals, and conventions that anticipated modern scientific approaches and from which the liberals might have profited. But the admiration of the conservatives for free growth generally applies only to the past. They typically lack the courage to welcome the same undesigned change from which new tools of human endeavors will emerge.
This brings me to the first point on which the conservative and the liberal dispositions differ radically. As has often been acknowledged by conservative writers, one of the fundamental traits of the conservative attitude is a fear of change, a timid distrust of the new as such, while the liberal position is based on courage and confidence, on a preparedness to let change run its course even if we cannot predict where it will lead. There would not be much to object to if the conservatives merely disliked too rapid change in institutions and public policy; here the case for caution and slow process is indeed strong. But the conservatives are inclined to use the powers of government to prevent change or to limit its rate to whatever appeals to the more timid mind. In looking forward, they lack the faith in the spontaneous forces of adjustment which makes the liberal accept changes without apprehension, even though he does not know how the necessary adaptations will be brought about. It is, indeed, part of the liberal attitude to assume that, especially in the economic field, the self-regulating forces of the market will somehow bring about the required adjustments to new conditions, although no one can foretell how they will do this in a particular instance. There is perhaps no single factor contributing so much to people’s frequent reluctance to let the market work as their inability to conceive how some necessary balance, between demand and supply, between exports and imports, or the like, will be brought about without deliberate control. The conservative feels safe and content only if he is assured that some higher wisdom watches and supervises change, only if he knows that some authority is charged with keeping the change “orderly.”
This fear of trusting uncontrolled social forces is closely related to two other characteristics of conservatism: its fondness for authority and its lack of understanding of economic forces. Since it distrusts both abstract theories and general principles, it neither understands those spontaneous forces on which a policy of freedom relies nor possesses a basis for formulating principles of policy. Order appears to the conservatives as the result of the continuous attention of authority, which, for this purpose, must be allowed to do what is required by the particular circumstances and not be tied to rigid rule. A commitment to principles presupposes an understanding of the general forces by which the efforts of society are co-ordinated, but it is such a theory of society and especially of the economic mechanism that conservatism conspicuously lacks. So unproductive has conservatism been in producing a general conception of how a social order is maintained that its modern votaries, in trying to construct a theoretical foundation, invariably find themselves appealing almost exclusively to authors who regarded themselves as liberal. Macaulay, Tocqueville, Lord Acton, and Lecky certainly considered themselves liberals, and with justice; and even Edmund Burke remained an Old Whig to the end and would have shuddered at the thought of being regarded as a Tory.
Let me return, however, to the main point, which is the characteristic complacency of the conservative toward the action of established authority and his prime concern that this authority be not weakened rather than that its power be kept within bounds. This is difficult to reconcile with the preservation of liberty. In general, it can probably be said that the conservative does not object to coercion or arbitrary power so long as it is used for what he regards as the right purposes. He believes that if government is in the hands of decent men, it ought not to be too much restricted by rigid rules. Since he is essentially opportunist and lacks principles, his main hope must be that the wise and the good will rule—not merely by example, as we all must wish, but by authority given to them and enforced by them. Like the socialist, he is less concerned with the problem of how the powers of government should be limited than with that of who wields them; and, like the socialist, he regards himself as entitled to force the value he holds on other people.
When I say that the conservative lacks principles, I do not mean to suggest that he lacks moral conviction. The typical conservative is indeed usually a man of very strong moral convictions. What I mean is that he has no political principles which enable him to work with people whose moral values differ from his own for a political order in which both can obey their convictions. It is the recognition of such principles that permits the coexistence of different sets of values that makes it possible to build a peaceful society with a minimum of force. The acceptance of such principles means that we agree to tolerate much that we dislike. There are many values of the conservative which appeal to me more than those of the socialists; yet for a liberal the importance he personally attaches to specific goals is no sufficient justification for forcing others to serve them. I have little doubt that some of my conservative friends will be shocked by what they will regard as “concessions” to modern views that I have made in Part III of this book. But, though I may dislike some of the measures concerned as much as they do and might vote against them, I know of no general principles to which I could appeal to persuade those of a different view that those measures are not permissible in the general kind of society which we both desire. To live and work successfully with others requires more than faithfulness to one’s concrete aims. It requires an intellectual commitment to a type of order in which, even on issues which to one are fundamental, others are allowed to pursue different ends.
It is for this reason that to the liberal neither moral nor religious ideals are proper objects of coercion, while both conservatives and socialists recognize no such limits. I sometimes feel that the most conspicuous attribute of liberalism that distinguishes it as much from conservatism as from socialism is the view that moral beliefs concerning matters of conduct which do not directly interfere with the protected sphere of other persons do not justify coercion. This may also explain why it seems to be so much easier for the repentant socialist to find a new spiritual home in the conservative fold than in the liberal.
In the last resort, the conservative position rests on the belief that in any society there are recognizably superior persons whose inherited standards and values and position ought to be protected and who should have a greater influence on public affairs than others. The liberal, of course, does not deny that there are some superior people—he is not an egalitarian—but he denies that anyone has authority to decide who these superior people are. While the conservative inclines to defend a particular established hierarchy and wishes authority to protect the status of those whom he values, the liberal feels that no respect for established values can justify the resort to privilege or monopoly or any other coercive power of the state in order to shelter such people against the forces of economic change. Though he is fully aware of the important role that cultural and intellectual elites have played in the evolution of civilization, he also believes that these elites have to prove themselves by their capacity to maintain their position under the same rules that apply to all others.
Closely connected with this is the usual attitude of the conservative to democracy. I have made it clear earlier that I do not regard majority rule as an end but merely as a means, or perhaps even as the least evil of those forms of government from which we have to choose. But I believe that the conservatives deceive themselves when they blame the evils of our time on democracy. The chief evil is unlimited government, and nobody is qualified to wield unlimited power. The powers which modern democracy possesses would be even more intolerable in the hands of some small elite.
Admittedly, it was only when power came into the hands of the majority that further limitation of the power of government was thought unnecessary. In this sense democracy and unlimited government are connected. But it is not democracy but unlimited government that is objectionable, and I do not see why the people should not learn to limit the scope of majority rule as well as that of any other form of government. At any rate, the advantages of democracy as a method of peaceful change and of political education seem to be so great compared with those of any other system that I can have no sympathy with the anti-democratic strain of conservatism. It is not who governs but what government is entitled to do that seems to me the essential problem.
That the conservative opposition to too much government control is not a matter of principle but is concerned with the particular aims of government is clearly shown in the economic sphere. Conservatives usually oppose collectivist and directivist measures in the industrial field, and here the liberal will often find allies in them. But at the same time conservatives are usually protectionists and have frequently supported socialist measures in agriculture. Indeed, though the restrictions which exist today in industry and commerce are mainly the result of socialist views, the equally important restrictions in agriculture were usually introduced by conservatives at an even earlier date. And in their efforts to discredit free enterprise many conservative leaders have vied with the socialists.
4. I have already referred to the differences between conservatism and liberalism in the purely intellectual field, but I must return to them because the characteristic conservative attitude here not only is a serious weakness of conservatism but tends to harm any cause which allies itself with it. Conservatives feel instinctively that it is new ideas more than anything else that cause change. But, from its point of view rightly, conservatism fears new ideas because it has no distinctive principles of its own to oppose to them; and, by its distrust of theory and its lack of imagination concerning anything except that which experience has already proved, it deprives itself of the weapons needed in the struggle of ideas. Unlike liberalism with its fundamental belief in the long-range power of ideas, conservatism is bound by the stock of ideas inherited at a given time. And since it does not really believe in the power of argument, its last resort is generally a claim to superior wisdom, based on some self-arrogated superior quality.
This difference shows itself most clearly in the different attitudes of the two traditions to the advance of knowledge. Though the liberal certainly does not regard all change as progress, he does regard the advance of knowledge as one of the chief aims of human effort and expects from it the gradual solution of such problems and difficulties as we can hope to solve. Without preferring the new merely because it is new, the liberal is aware that it is of the essence of human achievement that it produces something new; and he is prepared to come to terms with new knowledge, whether he likes its immediate effects or not.
Personally, I find that the most objectionable feature of the conservative attitude is its propensity to reject well-substantiated new knowledge because it dislikes some of the consequences which seem to follow from it—or, to put it bluntly, its obscurantism. I will not deny that scientists as much as others are given to fads and fashions and that we have much reason to be cautious in accepting the conclusions that they draw from their latest theories. But the reasons for our reluctance must themselves be rational and must be kept separate from our regret that the new theories upset our cherished beliefs. I can have little patience with those who oppose, for instance, the theory of evolution or what are called “mechanistic” explanations of the phenomena of life simply because of certain moral consequences which at first seem to follow from these theories, and still less with those who regard it as irreverent or impious to ask certain questions at all. By refusing to face the facts, the conservative only weakens his own position. Frequently the conclusions which rationalist presumption draws from new scientific insights do not at all follow from them. But only by actively taking part in the elaboration of the consequences of new discoveries do we learn whether or not they fit into our world picture and, if so, how. Should our moral beliefs really prove to be dependent on factual assumptions shown to be incorrect, it would be hardly moral to defend them by refusing to acknowledge facts.
Connected with the conservative distrust of the new and the strange is its hostility to internationalism and its proneness to a strident nationalism. Here is another source of its weakness in the struggle of ideas. It cannot alter the fact that the ideas which are changing our civilization respect no boundaries. But refusal to acquaint one’s self with new ideas merely deprives one of the power of effectively countering them when necessary. The growth of ideas is an international process, and only those who fully take part in the discussion will be able to exercise a significant influence. It is no real argument to say that an idea is un-American, un-British, or un-German, nor is a mistaken or vicious ideal better for having been conceived by one of our compatriots.
A great deal more might be said about the close connection between conservatism and nationalism, but I shall not dwell on this point because it may be felt that my personal position makes me unable to sympathize with any form of nationalism. I will merely add that it is this nationalistic bias which frequently provides the bridge from conservatism to collectivism: to think in terms of “our” industry or resource is only a short step away from demanding that these national assets be directed in the national interest. But in this respect the Continental liberalism which derives from the French Revolution is little better than conservatism. I need hardly say that nationalism of this sort is something very different from patriotism and that an aversion to nationalism is fully compatible with a deep attachment to national traditions. But the fact that I prefer and feel reverence for some of the traditions of my society need not be the cause of hostility to what is strange and different. Only at first does it seem paradoxical that the anti-internationalism of the conservative is so frequently associated with imperialism. But the more a person dislikes the strange and thinks his own ways superior, the more he tends to regard it as his mission to “civilize” others—not by the voluntary and unhampered intercourse which the liberal favors, but by bringing them the blessings of efficient government. It is significant that here again we frequently find the conservatives joining hands with the socialists against the liberals—not only in England, where the Webbs and their Fabians were outspoken imperialists, or in Germany, where state socialism and colonial expansionism went together and found the support of the same group of “socialists of the chair,” but also in the United States, where even at the time of the first Roosevelt it could be observed: “the Jingo and the Social Reformer have gotten together and have formed a political party, which threatened to capture the Government and use it for their program of Caesaristic paternalism, a danger which appears now to have been averted only by the other parties having themselves adopted this programme in a somewhat milder degree and form.”
5. There is one respect, however, in which there is justification for saying that the liberal occupies a position midway between the socialist and the conservative: he is as far from the crude rationalism of the socialist, who wants to reconstruct all social institutions according to a pattern prescribed by his individual reason, as from the mysticism to which the conservative so frequently has to resort. What I have described as the liberal position shares with conservatism a distrust of reason to the extent that the liberal is very much aware that we do not know all the answers and that he is not sure that the answers he has are certainly the right ones or even that we can find all the answers. He also does not disdain to seek assistance from whatever non-rational institutions or habits have proved their worth. The liberal differs from the conservative in his willingness to face this ignorance and to admit how little we know, without claiming the authority of supernatural sources of knowledge where his reason fails him. It has to be admitted that in some respects the liberal is fundamentally a skeptic—but it seems to require a certain degree of diffidence to let others seek their happiness in their own fashion and to adhere consistently to that tolerance which is an essential characteristic of liberalism.
There is no reason why this need mean an absence of religious belief on the part of the liberal. Unlike the rationalism of the French Revolution, true liberalism has no quarrel with religion, and I can only deplore the militant and essentially illiberal antireligionism which animated so much of nineteenth-century Continental liberalism. That this is not essential to liberalism is clearly shown by its English ancestors, the Old Whigs, who, if anything, were much too closely allied with a particular religious belief. What distinguishes the liberal from the conservative here is that, however profound his own spiritual beliefs, he will never regard himself as entitled to impose them on others and that for him the spiritual and the temporal are different spheres which ought not to be confused.
6. What I have said should suffice to explain why I do not regard myself as a conservative. Many people will feel, however, that the position which emerges is hardly what they used to call “liberal.” I must, therefore, now face the question of whether this name is today the appropriate name for the party of liberty. I have already indicated that, though I have all my life described myself as a liberal, I have done so more recently with increasing misgivings—not only because in the United States this term constantly gives rise to misunderstanding, but also because I have become more and more aware of the great gulf that exists between my position and the rationalistic Continental liberalism or even the English liberalism of the utilitarians.
If liberalism still meant what it meant to an English historian who in 1827 could speak of the revolution of 1688 as “the triumph of those principles which, in the language of the present day, are denominated liberal or constitutional” or if one could still, with Lord Acton, speak of Burke, Macaulay, and Gladstone as the three greatest liberals, or if one could still, with Harold Laski, regard Tocqueville and Lord Acton as “the essential liberals of the nineteenth century,” I should indeed be only too proud to describe myself by that name. But, much as I am tempted to call their liberalism true liberalism, I must recognize that the majority of Continental liberals stood for ideas to which these men were strongly opposed, and that they were led more by a desire to impose upon the world a preconceived rational pattern than to provide opportunity for free growth. The same is largely true of what has called itself Liberalism in England at least since the time of Lloyd George.
It is thus necessary to recognize that what I have called “liberalism” has little to do with any political movement that goes under that name today. It is also questionable whether the historical associations which that name carries today are conducive to the success of any movement. Whether in these circumstances one ought to make an effort to rescue the term from what one feels is its misuse is a question on which opinions may well differ. I myself feel more and more that to use it without long explanations causes too much confusion and that as a label it has become more of a ballast than a source of strength.
In the United States, where it has become almost impossible to use “liberal” in the sense in which I have used it, the term “libertarian” has been used instead. It may be the answer; but for my part I find it singularly unattractive. For my taste it carries too much the flavor of a manufactured term and of a substitute. What I should want is a word which describes the party of life, the party that favors free growth and spontaneous evolution. But I have racked my brain unsuccessfully to find a descriptive term which commends itself.
7. We should remember, however, that when the ideals which I have been trying to restate first began to spread through the Western world, the party which represented them had a generally recognized name. It was the ideals of the English Whigs that inspired what later came to be known as the liberal movement in the whole of Europe and that provided the conceptions that the American colonists carried with them and which guided them in their struggle for independence and in the establishment of their constitution. Indeed, until the character of this tradition was altered by the accretions due to the French Revolution, with its totalitarian democracy and socialist leanings, “Whig’’ was the name by which the party of liberty was generally known.
The name died in the country of its birth partly because for a time the principles for which it stood were no longer distinctive of a particular party, and partly because the men who bore the name did not remain true to those principles. The Whig parties of the nineteenth century, in both Britain and the United States, finally brought discredit to the name among the radicals. But it is still true that, since liberalism took the place of Whiggism only after the movement for liberty had absorbed the crude and militant rationalism of the French Revolution, and since our task must largely be to free that tradition from the overrationalistic, nationalistic, and socialistic influences which have intruded into it, Whiggism is historically the correct name for the ideas in which I believe. The more I learn about the evolution of ideas, the more I have become aware that I am simply an unrepentant Old Whig—with the stress on the “old.”
To confess one’s self an Old Whig does not mean, of course, that one wants to go back to where we were at the end of the seventeenth century. It has been one of the purposes of this book to show that the doctrines then first stated continued to grow and develop until about seventy or eighty years ago, even though they were no longer the chief aim of a distinct party. We have since learned much that should enable us to restate them in a more satisfactory and effective form. But, though they require restatement in the light of our present knowledge, the basic principles are still those of the Old Whigs. True, the later history of the party that bore that name has made some historians doubt where there was a distinct body of Whig principles; but I can but agree with Lord Acton that, though some of “the patriarchs of the doctrine were the most infamous of men, the notion of a higher law above municipal codes, with which Whiggism began, is the supreme achievement of Englishmen and their bequest to the nation”—and, we may add, to the world. It is the doctrine which is at the basis of the common tradition of the Anglo-Saxon countries. It is the doctrine from which Continental liberalism took what is valuable in it. It is the doctrine on which the American system of government is based. In its pure form it is represented in the United States, not by the radicalism of Jefferson, nor by the conservatism of Hamilton or even of John Adams, but by the ideas of James Madison, the “father of the Constitution.”
I do not know whether to revive that old name is practical politics. That to the mass of people, both in the Anglo-Saxon world and elsewhere, it is today probably a term without definite associations is perhaps more an advantage than a drawback. To those familiar with the history of ideas it is probably the only name that quite expresses what the tradition means. That, both for the genuine conservative and still more for the many socialists turned conservative, Whiggism is the name for their pet aversion shows a sound instinct on their part. It has been the name for the only set of ideals that has consistently opposed all arbitrary power.
8. It may well be asked whether the name really matters so much. In a country like the United States, which on the whole still has free institutions and where, therefore, the defense of the existing is often a defense of freedom, it might not make so much difference if the defenders of freedom call themselves conservatives, although even here the association with the conservatives by disposition will often be embarrassing. Even when men approve of the same arrangements, it must be asked whether they approve of them because they exist or because they are desirable in themselves. The common resistance to the collectivist tide should not be allowed to obscure the fact that the belief in integral freedom is based on an essentially forward-looking attitude and not on any nostalgic longing for the past or a romantic admiration for what has been.
The need for a clear distinction is absolutely imperative, however, where, as is true in many parts of Europe, the conservatives have already accepted a large part of the collectivist creed—a creed that has governed policy for so long that many of its institutions have come to be accepted as a matter of course and have become a source of pride to “conservative” parties who created them. Here the believer in freedom cannot but conflict with the conservative and take an essentially radical position, directed against popular prejudices, entrenched positions, and firmly established privileges. Follies and abuses are no better for having long been established principles of policy.
Though quieta non movere may at times be a wise maxim for the statesman, it cannot satisfy the political philosopher. He may wish policy to proceed gingerly and not before public opinion is prepared to support it, but he cannot accept arrangements merely because current opinion sanctions them. In a world where the chief need is once more, as it was at the beginning of the nineteenth century, to free the process of spontaneous growth from the obstacles and encumbrances that human folly has erected, his hopes must rest on persuading and gaining the support of those who by disposition are “progressives,” those who, though they may now be seeking change in the wrong direction, are at least willing to examine critically the existing and to change it wherever necessary.
I hope I have not misled the reader by occasionally speaking of “party” when I was thinking of groups of men defending a set of intellectual and moral principles. Party politics of any one country has not been the concern of this book. The question of how the principles I have tried to reconstruct by piecing together the broken fragments of a tradition can be translated into a program with mass appeal, the political philosopher must leave to “that insidious and crafty animal, vulgarly called a statesman or politician, whose councils are directed by the momentary fluctuations of affairs.” The task of the political philosopher can only be to influence public opinion, not to organize people for action. He will do so effectively only if he is not concerned with what is now politically possible but consistently defends the “general principles which are always the same.” In this sense I doubt whether there can be such a thing as a conservative political philosophy. Conservatism may often be a useful practical maxim, but it does not give us any guiding principles which can influence long-range developments.
