The Idea of Congruence
Stated very briefly, the first proposition of the theory I would suggest is that a government will tend to be stable if its authority pattern is congruent with the other authority patterns of the society of which it is a part . The crucial term in this proposition is of course "congruence," and it needs to be defined, particularly since, as used here, the term is not at all self-explanatory.
Authority patterns are congruent, in the first place (but only in the first place), if they are identical (that is to say, since we are dealing not with an abstract geometric universe but real life, if they very closely resemble each other). An example of congruence in this sense is furnished by the authority patterns in British government and British political parties, at any rate if we accept the standard analyses of the latter by Beer and McKenzie.[8] Both patterns consist of a curious and very similar mixture of democratic, authoritarian, and, so to speak, constitutional elements; this despite the fact that British government can be traced back to the eras of medieval constitutionalism and royal absolutism, while political parties are, in almost every respect, creatures of a much later period, the era of the mandate; and this also despite the fact that the formal constitution of the Labour party makes it seem very different from both the Conservative party and the British governmental structure.[9] In both government and parties, the idea of the mandate is formalized and paid considerably more than lip service, in one case in the House of Commons, in the other in the Annual Conferences. In both cases, however, the leaders actually enjoy long tenure in office and a great deal of autonomy, even though the autonomy of the Conservative Leader rests on formal rules and that of the Labour Leader "merely" on actual practice; in both cases, moreover, the idea of the mandate is contravened by the fact that the leaders are widely expected to govern, in the sense of taking personal policy initiatives and sometimes even acting contrary to opinion in the rank and file. In both cases, too, this autonomy of leadership is mitigated by the expectation—on the part, incidentally, of both elites and masses—that authority will be exercised "constitutionally"; that is to say, that it will be exercised, if not in conformity with written documents, then at least within a framework of widely accepted and well-understood limits and rules, including, for example, the rule that authority inheres always in a collective structure, whether this structure is provided for in a formal constitution, as in the Labour party, or not, as in the Conservative party and the governmental machinery. In addition to these absolutely fundamental resemblances, there are also many less basic, although no less striking, similarities between
British government and parties. For example, both Parliament and the parliamentary organizations of the parties have largely an advisory and exhortatory role in decision-making processes; in both Parliament and the party conferences, the leaders are given certain traditional privileges in debates (they speak longer, for example, and more frequently); in both government and parties, bureaucracy plays an indispensable but subordinate and unusually self-effacing role, even in this age of massive government and massive parties; and, of course, government and party leaders entirely coincide, a fact that the Weimar parties show to be by no means inevitable in a parliamentary system.
The essential patterns of cabinet government, and the essential attitudes on which it is based, thus all have their counterparts in the major British parties. In fact, it has been argued, cogently I think, that cabinet government on the British model compels a certain correspondence between party structure and governmental structure, certainly while a party is in power, and therefore also perhaps while it is in opposition and presumably aspiring to power. Cabinet government could not otherwise work at all on a party basis; hence the anxieties of many English citizens when the Labour party strays, as it infrequently does, from the model of the cabinet system and acts as if it really believed in its formal constitution. But this argument should not be taken to mean that British parties cannot help but have a structure similar to that of British government. "Compel" does not in this case mean "cause." The argument means merely that British government can work smoothly only if such a congruence of governmental and party structures exists, not that things could not actually be otherwise. There are plenty of parliamentary systems in which the same logic holds, but few in which the same congruence can be found.
The most extreme and plainest form of congruence, then, is identity. Mixing metaphors, we might speak in this case of isomorphic authority patterns. But identity cannot exhaust the meaning of congruence when applied to social phenomena, for it is difficult even to imagine a society in which all authority patterns closely resemble each other. Certainly such a state of affairs is impossible in a democracy. Some social relations simply cannot be conducted in a democratic manner, or can be so conducted only with the gravest dysfunctional consequences. Take, for example, those social units which link different generations—families and schools. An infant cannot be cared for democratically, or a child brought up and schooled democratically. Families and schools can be permissive, but this is merely to say that they can be authoritarian in a lax and lenient manner. Families and schools can also carry on a certain amount of democratic pretense, and indeed more than pretense, and when they do so on a large scale, that fact is not without significance; but by and large they cannot carry such simulation and imitation of democracy to very great lengths, if they
are not to produce warped and ineffectual human beings. One of the most basic and indispensable functions in any social system, the socialization function, must therefore always be to some extent out of tune with democratic patterns and potentially at odds with them. The same point applies, almost as obviously, to certain relations among adults. We have every reason to think that economic organizations cannot be organized in a truly democratic manner, at any rate not without consequences that no one wants; and we certainly know that capitalist economic organization and even certain kinds of public ownership (like the nationalization in Britain of industries absolutely vital to the health of the whole economy) militate against a democratization of economic relations. The case of military organizations is even plainer in this regard, and the case of public bureaucracy just as clear. Again, there can be some simulation and imitation of democracy in firms, or public offices, or military units, but only within rather narrow limits. Precisely those social relations in which most individuals are engaged most of the time—family life, schools, and jobs (most kinds of jobs)—are the least capable of being democratically organized. To expect all authority relations in a democracy to be identical would therefore be unreasonable, and we could probably demonstrate the same thing, in other ways, for other kinds of governmental structures. In any complex society, but above all in democracies, we must expect some heterogeneity in authority patterns, even if we deal only with fundamental patterns and not circumstantial details.
In that case, however, one can still speak meaningfully of a congruence of authority patterns if the patterns have a certain "fit" with one another—if they dovetail with, or support, the governmental pattern, however indirectly. One way in which they can do this is by the partial imitation of the governmental authority patterns in other social structures. Democratic (or other) pretenses, if taken seriously and carried far, may have important consequences for the operation of the governmental structure, even though they are pretenses. Furthermore, structures like economic or military organizations may, in some cases, willingly incur certain functional disadvantages for the sake of acting out norms associated with governments in their substantive decision-making processes. For instance, capitalistic economic organizations, which play a great deal at democracy and permit certain deviations from the logic of the double-entry ledger in order actually to carry on certain democratic practices, may be said to be more congruent with democratic government than those that stick closely, both in ritual and process, to the economically most rational practices.
In view of this, we might be tempted to say that authority patterns are congruent if they have, not everything, but something in common. But if the equation of congruence with identity makes demands that are too great, its equation with mere resemblance, however slight, does not demand
enough. On the first basis, we shall almost never find a society in which authority patterns are really congruent; on the second, we shall assuredly not find any in which authority patterns are incongruent. However, by congruence I do not mean any resemblance at all among authority patterns. Where authority relations are not all highly similar, the term refers rather to a particular pattern of resemblance among them, one that makes stringent requirements, but not requirements impossible to fulfill—a pattern of graduated resemblances , so to speak.
To grasp the concept of graduated resemblances, one must think of societies as being composed of segments that are more or less distant from government. Governments themselves are adult structures, and for this reason families, for example, are more "vertically" distant from them, in terms of age levels, than schools, and schools more distant from them than purely adult structures. In the same way, adult structures may be "horizontally" segmented, so that some appear close to, others distant from, government. Parties, for example, ordinarily are situated closer to government than pressure groups; among pressure groups certain types may be particularly closely involved in government or parties; and all pressure groups are located more closely to government than nonpolitical organizations. These are very rough breakdowns; in some concrete cases, moreover, it may be difficult to make unambiguous distinctions, and the same social structures will not always fall into the same positions in every society. But none of this affects the definition: that social authority patterns are congruent, either if they are very similar, or if similarity to the governmental pattern increases significantly as one approaches the governmental segment itself.
On the basis of these explications of the term "congruence," we can now restate the first proposition of the theory. Government will be stable , (1) if social authority patterns are identical with the governmental pattern , or (2) if they constitute a graduated pattern in a proper segmentation of society , or (3) if a high degree of resemblance exists in patterns adjacent to government and one finds throughout the more distant segments a marked departure from functionally appropriate patterns for the sake of imitating the governmental pattern or extensive imitation of the governmental pattern in ritual practices . Conditions (2) and (3) are both, of course, looser and less demanding versions of condition (1); all refer to a basic need for considerable resemblance in authority patterns if government is to be stable, particularly in those segments of society which impinge directly on government. Condition (3) may be regarded, in this way, as the minimum required for governmental stability (and the minimum meaning of congruence), but perhaps the most that can be realized in relation to some particular pattern of government. By the same token, governments will be unstable (and the authority patterns of a society incongruent) if the governmental authority pattern is isolated (that

is, substantially different) from those of other social segments, or if a very abrupt change in authority pattern occurs in any adjacent segments of society, or if several different authority patterns exist in social strata furnishing a large proportion of the political elite (in the sense of active political participants). In the last case, congruence with the authority patterns of a particular part of the elite—say, a particular social class—may be quite possible, but congruence with the overall authority patterns of a society is logically out of the question.
