Our problem arises from the fact that aggressive attitudes on the part of states—or of such earlier organizational structures as history may record—can be explained, directly and unequivocally, only in part by the real and concrete interests of the people. Examples will best illustrate what we mean. When two tribes come into conflict over essential salt deposits or hunting grounds; or when a state, hemmed in on all sides by customs and communication barriers, resorts to aggression in order to gain access to the sea, we have a case in which aggression is explained by interests. It is true that there are many methodological difficulties in speaking of the interests of a people as such. Here, however, reference to “concrete” interests explains everything that would seem to stand in need of explanation. A concrete interest need not be economic in character. When a state resorts to aggression in order to unite its citizens politically, as was the case with Piedmont in 1848 and 1859, this likewise betokens a real, concrete interest, explaining its conduct. The interest, moreover, need not necessarily extend to the entire population of the state. When a planter aristocracy prevails upon its government to seize some foreign base of operations for the slave trade, this too is explained by a real, concrete interest. The interest that actually explains a warlike act need not, finally, be openly admitted—or of the kind that can be openly admitted; it need not, to use our own term, be an avowed interest. Such cases nevertheless come under the present heading, if the concrete interests of a sufficiently powerful class are accessible to scientific consideration. There are, on the other hand, certain cases that do not belong here, such as that of a group of people who contrive to have a declaration of war issued because they gain financially from the waging of war, or because they need a war as a diversion from domestic political difficulties. Here there is no concrete interest, in the sense that applies to the aforementioned cases. True, there must be some concrete interest. There must be a reason for the declaration of war. But that reason is not the cause. The true cause, of course, must also lie in an interest. But that interest is not in the concrete war aims. It is not a question of the advantages offered by the attainment of those aims, but of an interest in the waging of war as such. The questions that then arise are how the people came to acquire such a generally belligerent disposition and why they happened to choose this particular occasion for war. Thus mere reference to a concrete interest is satisfactory under only three conditions: In the first place, such a concrete interest must be present, in the sense that has now been made clear—an interest which the observer can grasp as such, of course taking into account the social structure, mentality, and situation of the people in question. In the second place, the conduct of the state which is under study must be calculated to promote this interest, with the sum total of predictable sacrifices and risks in some proportion to the anticipated gains. In the third place, it must be possible to prove that this interest, whether avowed or not, is actually the political driving force behind the action.
In the individual case it may often become difficult to establish whether these conditions obtain. The fabric of social interests is so closely woven that scarcely ever can there be any action on the part of a state that is not in keeping with the concrete interest of someone, an interest to which that action can be reduced without manifest absurdity. To this must be added the belief, inculcated into the people, especially in the present age, that concrete interests of the people dictate the behavior of the state and that concrete advantages for all classes are to be expected. Government policies are always officially justified in this way, and often, without the slightest doubt, in perfect good faith. Finally, current fallacies, especially of an economic character, may serve to create the semblance of an adequate, concrete interest in the mind of the people—and occasionally even in the mind of the scientific observer, especially the historian. In such cases the true background is laid bare only by inquiry into the manner in which the people came to their belief. But the individual case does not concern us. We are concerned only with the fact, which is beyond doubt, that the three above-mentioned conditions are frequently not fulfilled. Whenever such is the case, a problem arises. And among the problems of this nature is the problem of imperialism.
No one calls it imperialism when a state, no matter how brutally and vigorously, pursues concrete interests of its own; and when it can be expected to abandon its aggressive attitude as soon as it has attained what it was after. The word “imperialism” has been abused as a slogan to the point where it threatens to lose all meaning, but up to this point our definition is quite in keeping with common usage, even in the press. For whenever the word imperialism is used, there is always the implication—whether sincere or not—of an aggressiveness, the true reasons for which do not lie in the aims which are temporarily being pursued; of an aggressiveness that is only kindled anew by each success; of an aggressiveness for its own sake, as reflected in such terms as “hegemony,” “world dominion,” and so forth. And history, in truth, shows us nations and classes—most nations furnish an example at some time or other—that seek expansion for the sake of expanding, war for the sake of fighting, victory for the sake of winning, dominion for the sake of ruling. This determination cannot be explained by any of the pretexts that bring it into action, by any of the aims for which it seems to be struggling at the time. It confronts us, independent of all concrete purpose or occasion, as an enduring disposition, seizing upon one opportunity as eagerly as the next. It shines through all the arguments put forward on behalf of present aims. It values conquest not so much on account of the immediate advantages—advantages that more often than not are more than dubious, or that are heedlessly cast away with the same frequency—as because it is conquest, success, action. Here the theory of concrete interest in our sense fails. What needs to be explained is how the will to victory itself came into being.
Expansion for its own sake always requires, among other things, concrete objects if it is to reach the action stage and maintain itself, but this does not constitute its meaning. Such expansion is in a sense its own “object,” and the truth is that it has no adequate object beyond itself. Let us therefore, in the absence of a better term, call it “objectless.” It follows for that very reason that, just as such expansion cannot be explained by concrete interest, so too it is never satisfied by the fulfillment of a concrete interest, as would be the case if fulfillment were the motive, and the struggle for it merely a necessary evil—a counterargument, in fact. Hence the tendency of such expansion to transcend all bounds and tangible limits, to the point of utter exhaustion. This, then, is our definition: imperialism is the objectless disposition on the part of a state to unlimited forcible expansion.
Now it may be possible, in the final analysis, to give an “economic explanation” for this phenomenon, to end up with economic factors. Two different points present themselves in this connection: First, an attempt can be made, following the basic idea of the economic interpretation of history, to derive imperialist tendencies from the economic-structural influences that shape life in general and from the relations of production. I should like to emphasize that I do not doubt in the least that this powerful instrument of analysis will stand up here in the same sense that it has with other, similar phenomena—if only it is kept in mind that customary modes of political thought and feeling in a given age can never be mere “reflexes” of, or counterparts to, the production situation of that age. Because of the persistence of such habits, they will always, to a considerable degree, be dominated by the production context of past ages. Again, the attempt may be made to reduce imperialist phenomena to economic class interests of the age in question. This is precisely what neo-Marxist theory does. Briefly, it views imperialism simply as the reflex of the interests of the capitalist upper stratum, at a given stage of capitalist development. Beyond doubt this is by far the most serious contribution toward a solution of our problem. Certainly there is much truth in it. We shall deal with this theory later. But let us emphasize even here that it does not, of logical necessity, follow from the economic interpretation of history. It may be discarded without coming into conflict with that interpretation; indeed, without even departing from its premises. It is the treatment of this factor that constitutes the contribution of the present inquiry into the sociology of the Zeitgeist.1
Our method of investigation is simple: we propose to analyze the birth and life of imperialism by means of historical examples which I regard as typical. A common basic trait emerges in every case, making a single sociological problem of imperialism in all ages, though there are substantial differences among the individual cases. Hence the plural, “imperialisms,” in the title.
