If wandering is the liberation from every given point in space, and thus the conceptional opposite to fixation at such a point, the sociological form of the "stranger" presents the unity, as it were, of these two characteristics. This phenomenon too, however, reveals that spatial relations are only the condition, on the one hand, and the symbol, on the other, of human relations. The stranger is thus being discussed here, not in the sense often touched upon in the past, as the wanderer who comes today and goes tomorrow, but rather as the person who comes today and stays to morrow. He is, so to speak, the potential wanderer: although he has not moved on, he has not quite overcome the freedom of coming and going. He is fixed within a particular spatial group, or within a group whose boundaries are similar to spatial boundaries. But his position in this group is determined, essentially, by the fact that he has not belonged to it from the beginning, that he imports qualities into it, which do not and cannot stem from the group itself.
The unity of nearness and remoteness involved in every human relation is organized, in the phenomenon of the stranger, in a way which may be most briefly formulated by saying that in the relationship to him, distance means that he, who is close by, is far, and strangeness means that he, who also is far, is actually near. For, to be a stranger is naturally a very positive relation; it is a specific form of interaction. The inhabitants of Sirius are not really strangers to us, at least not in any social logically relevant sense: they do not exist for us at all; they are beyond far and near. The stranger, like the poor and like sundry "inner enemies," is an element of the group itself. His position as a full-fledged member involves both being outside it and confronting it. The following statements, which are by no means intended as exhaustive, indicate how elements which increase distance and repel, in the relations of and with the stranger produce a pattern of coordination and consistent interaction.
Throughout the history of economics the stranger everywhere appears as the trader, or the trader as stranger. As long as economy is essentially self-sufficient, or products are exchanged within a spatially narrow group, it needs no middleman: a trader is only required for products that originate outside the group. Insofar as members do not leave the circle in order to buy these necessities--in which case they are the "strange" merchants in that outside territory--the trader must be a stranger, since nobody else has a chance to make a living.
This position of the stranger stands out more sharply if he settles down in the place of his activity, instead of leaving it again: in innumerable cases even this is possible only if he can live by intermediate trade. Once an economy is somehow closed the land is divided up, and handicrafts are established that satisfy the demand for them, the trader, too, can find his existence. For in trade, which alone makes possible unlimited combinations, intelligence always finds expansions and new territories, an achievement which is very difficult to attain for the original producer with his lesser mobility and his dependence upon a circle of customers that can be increased only slowly. Trade can always absorb more people than primary production; it is, therefore, the sphere indicated for the stranger, who intrudes as a supernumerary, so to speak, into a group in which the economic positions are actually occupied--the classical example is the history of European Jews. The stranger is by nature no "owner of soil"--soil not only in the physical, but also in the figurative sense of a life-substance which is fixed, if not in a point in space, at least in an ideal point of the social environment. Although in more intimate relations, he may develop all kinds of charm and significance, as long as he is considered a stranger in the eyes of the other, he is not an "owner of soil." Restriction to intermediary trade, and often (as though sublimated from it) to pure finance, gives him the specific character of mobility. If mobility takes place within a closed group, it embodies that synthesis of nearness and distance which constitutes the formal position of the stranger. For, the fundamentally mobile person comes in contact, at one time or another, with every individual, but is not organically connected, through established ties of kinship, locality, and occupation, with any single one.
Another expression of this constellation lies in the objectivity of the stranger. He is not radically committed to the unique ingredients and peculiar tendencies of the group, and therefore approaches them with the specific attitude of "objectivity." But objectivity does not simply involve passivity and detachment; it is a particular structure composed of distance and nearness, indifference and involvement. I refer to the discussion (in the chapter on "Superordination and Subordination" ) of the dominating positions of the person who is a stranger in the group; its most typical instance was the practice of those Italian cities to call their judges from the outside, because no native was free from entanglement in family and party interests.
With the objectivity of the stranger is connected, also, the phenomenon touched upon above,  although it is chiefly (but not exclusively) true of the stranger who moves on. This is the fact that he often receives the most surprising openness--confidences which sometimes have the character of a confessional and which would be carefully withheld from a more closely related person. Objectivity is by no means non-participation (which is altogether outside both subjective and objective interaction), but a positive and specific kind of participation--just as the objectivity of a theoretical observation does not refer to the mind as a passive tabula rasa on which things inscribe their qualities, but on the contrary, to its full activity that operates according to its own laws, and to the elimination, thereby, of accidental dislocations and emphases, whose individual and subjective differences would produce different pictures of the same object.
Objectivity may also be defined as freedom: the objective individual is bound by no commitments which could prejudice his perception, understanding, and evaluation of the given. The freedom, however, which allows the stranger to experience and treat even his close relationships as though from a bird's-eye view, contains many dangerous possibilities. In uprisings of all sorts, the party attacked has claimed, from the beginning of things, that provocation has come from the outside, through emissaries and instigators. Insofar as this is true, it is an exaggeration of the specific role of the stranger: he is freer practically and theoretically; he surveys conditions with less prejudice; his criteria for them are more general and more objective ideals; he is not tied down in his action by habit, piety, and precedent. 
Finally, the proportion of nearness and remoteness which gives the stranger the character of objectivity, also finds practical expression in the more abstract nature of the relation to him. That is, with the stranger one has only certain more general qualities in common, whereas the relation to more organically connected persons is based on the commonness of specific differences from merely general features. In fact, all somehow personal relations follow this scheme in various patterns. They are determined not only by the circumstance that certain common features exist among the individuals, along with individual differences, which either influence the relationship or remain outside of it. For, the common features themselves are basically determined in their effect upon the relation by the question whether they exist only between the participants in this particular relationship, and thus are quite general in regard to this relation, but are specific and incomparable in regard to everything outside of it--or whether the participants feel that these features are common to them because they are common to a group, a type, or mankind in general. In the case of the second alternative, the effectiveness of the common features becomes diluted in proportion to the size of the group composed of members who are similar in this sense. Although the commonness functions as their unifying basis, it does not make these particular persons interdependent on one another, because it could as easily connect everyone of them with all kinds of individuals other than the members of his group. This too, evidently, is a way in which a relationship includes both nearness and distance at the same time: to the extent to which the common features are general, they add, to the warmth of the relation founded on them, an element of coolness, a feeling of the contingency of precisely this relation--the connecting forces have lost their specific and centripetal character.
In the relation to the stranger, it seems to me, this constellation has an extraordinary and basic preponderance over the individual elements that are exclusive with the particular relationship. The stranger is close to us, insofar as we feel between him and ourselves common features of a national, social, occupational, or generally human, nature. He is far from us, insofar as these common features extend beyond him or us, and connect us only because they connect a great many people.
A trace of strangeness in this sense easily enters even the most intimate relationships. In the stage of first passion, erotic relations strongly reject any thought of generalization: the lovers think that there has never been a love like theirs; that nothing can be compared either to the person loved or to the feelings for that person. An estrangement--whether as cause or as consequence it is difficult to decide usually comes at the moment when this feeling of uniqueness vanishes from the relationship. A certain skepticism in regard to its value, in itself and for them, attaches to the very thought that in their relation, after all, they carry out only a generally human destiny; that they experience an experience that has occurred a thousand times before; that, had they not accidentally met their particular partner, they would have found the same significance in another person.
Something of this feeling is probably not absent in any relation, however close, because what is common to two is never common to them alone, but is subsumed under a general idea which includes much else besides, many possibilities of commonness. No matter how little these possibilities become real and how often we forget them, here and there, nevertheless, they thrust themselves between us like shadows, like a mist which escapes every word noted, but which must coagulate into a solid bodily form before it can be called jealousy. In some cases, perhaps the more general, at least the more unsurmountable, strangeness is not due to different and ununderstandable matters. It is rather caused by the fact that similarity, harmony, and nearness are accompanied by the feeling that they are not really the unique property of this particular relationship: they are something more general, something which potentially prevails between the partners and an indeterminate number of others, and therefore gives the relation, which alone was realized, no inner and exclusive necessity.
On the other hand, there is a kind of "strangeness" that rejects the very commonness based on something more general which embraces the parties. The relation of the Greeks to the Barbarians is perhaps typical here, as are all cases in which it is precisely general attributes, felt to be specifically and purely human, that are disallowed to the other. But "stranger," here, has no positive meaning; the relation to him is a non-relation; he is not what is relevant here, a member of the group itself.
As a group member, rather, he is near and far at the same time, as is characteristic of relations founded only on generally human commonness. But between nearness and distance, there arises a specific tension when the consciousness that only the quite general is common, stresses that which is not common. In the case of the person who is a stranger to the country, the city, the race, etc., however, this non-common element is once more nothing individual, but merely the strangeness of origin, which is or could be common to many strangers. For this reason, strangers are not really conceived as individuals, but as strangers of a particular type: the element of distance is no less general in regard to them than the element of nearness.
This form is the basis of such a special case, for instance, as the tax levied in Frankfort and elsewhere upon medieval Jews. Whereas the Beede [tax] paid by the Christian citizen changed with the changes of his fortune, it was fixed once for all for every single Jew. This fixity rested on the fact that the Jew had his social position as a Jew, not as the individual bearer of certain objective contents. Every other citizen was the owner of a particular amount of property, and his tax followed its fluctuations. But the Jew as a taxpayer was, in the first place, a Jew, and thus his tax situation had an invariable element. This same position appears most strongly, of course, once even these individual characterizations (limited though they were by rigid invariance) are omitted, and all strangers pay an altogether equal head-tax.
In spite of being inorganically appended to it, the stranger is yet an organic member of the group. Its uniform life includes the specific conditions of this element. Only we do not know how to designate the peculiar unity of this position other than by saying that it is composed of certain measures of nearness and distance. Although some quantities of them characterize all relationships, a special proportion and reciprocal tension produce the particular, formal relation to the "stranger."

10. But where the attacked make the assertion falsely, they do so from the tendency of those in higher position to exculpate inferiors, who, up to the rebellion, have been in a consistently close relation with them. For, by creating the fiction that the rebels were not really guilty, but only instigated, and that the rebellion did not really start with them, they exonerate themselves, inasmuch as they altogether deny all real grounds for the uprising.
