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.
